Welcome to Omnia.ONE!
I wish to offer my sincere gratitude on behalf of our company and welcome you to Omnia.ONE!
This manual was assembled by a dedicated team of specialists who were instrumental in the development
of our newest product, Omnia.ONE. This is our next step in the never-ending quest to build the best signal
processor in the world. Considerably more powerful than what its small package implies, Omnia.ONE
possesses new hardware and algorithm capabilities that even exceed its predecessors. It is also the first
audio processor to incorporate LiveWire connectivity, enabling linear audio over dedicated networks. It’s
the hottest ‘interconnect’ technology in the professional audio industry today.
Broadcasters require a lot of flexibility in an audio processor because transmission systems exist in many
different forms. The processor you choose must have the tools to meet those needs. Special firmware inside
Omnia.ONE allows it to meet the challenges of FM, AM, HD Radio, DAB, DRM, Multicasting,
Podcasting, Netcasting, Satcasting, and any other form of ‘casting’ you can think of. There’s plenty of
power inside its little 1U frame, so don’t let the size fool you!
It was 1986, in the engineering shop at Z-100, (WHTZ-FM) New York City where our first product was
born - The Vigilante FM Limiter. Twenty-one years later and with an incredibly talented team of designers
behind it, we offer you the newest baby in our ever-growing family, Omnia.ONE!
Speaking of the team, I wish to offer a sincere and heart-felt thank you to: Rob Dye, Bill Mohat, Ed
Zmuginsky, Mark Manolio, Ted Alexander, David Jablonski, Scott Stiefel, Sean Overberger, Betty Ferrell,
Steve Kiffmeyer, Denny Sanders, Marty Sacks, Mike Dosch, Kirk Harnack, Mike Uhl, Jim “Clemenza”
Armstrong, Marc Johnson, Ken Skok and a host of others (as you can see, it’s not just “Frank” anymore!).
It’s a great team of people who always maintain one goal in their minds…keep raising the bar!
Steve Church, my partner in crime and founder of Telos, first introduced DSP technology to broadcasting
in 1985. Our team of DSP gurus is the finest in the audio industry. Our own specialized DSP ingenuity has
been tremendously beneficial to Omnia’s development.
You have in your possession an incredible audio processor. Also, you have the full support of our entire
organization standing behind the product. If you have feedback, or even a new idea, we’re here to listen!
Customers, like you, offer us valuable feedback. After all, it’s feedback like yours that helped us introduce
the original Omnia.fm, and then take the industry by storm. Our quest today, just as it has been all along, is
to continue to be the audio processing brand leader.
To borrow a phrase from my old stomping grounds, Z-100 in New York City, Omnia went from worst to
first in the minds and ears of radio broadcasters. We are honored, equally humbled to say the least, and
grateful to you, our customers, for helping us make that happen! Omnia processors have been installed by
tens of thousands of broadcasters throughout the world, and I am overwhelmed when I look at the list of
our end-users. So, it’s to you, our loyal customers and friends, that I say Thank You!
To Great Sounding Audio…the World over!

Sensus® Technology: Audio Processingx3
Overview
Until now, digital signal processing has been a more precise numeric implementation of well-known
analog methods. Even relatively recently designed digital audio processors couldn’t veer too far
from the comparatively simplistic concepts that analog dynamics processing had utilized… until
now!
Extremely high power DSP chips have become available and at relatively low cost, and they make it
possible to build smarter and more complex processing algorithms that were too difficult or
impossible (or too expensive) to do in the past.
Running on a platform of the latest high power DSP chips, the OmniaONE and our new Sensus®
technology takes digital dynamics processing into a completely new frontier. Instead of the two-
dimensional static processing architecture of the past, Sensus® enables the audio processor to
modify its own architecture in real time and in response to ever-changing program content.
Simply stated, Sensus® has the ability to “sense” what must be done to a signal in order to best tailor
it for the following codec. As program content changes, it “rearranges the algorithms” to accomplish
this goal. The uniqueness of the Sensus® technology makes it highly suitable not only for codec pre-
conditioning (or provisioning), but also for a range of other highly specialized signal processing
challenges. The following is a discussion of how Sensus® technology can be applied to a coded
audio environment.
Codec Provisioning
The codec is now a common denominator in the world of audio and broadcasting. Digital
broadcasting (HDTV, HD-RadioR, DAB, DRM), podcasting, webcasting, cellcasting, and
downloadable music files all employ a form of codec-based data compression in order to minimize
the bandwidth required to transmit data. The necessarily low bitrates utilized by these mediums
presents a tough challenge for any audio processor used prior to a codec.
Traditional dynamics processors were designed to fulfill the requirements of a medium where the
functions were generally static. That is, they were well suited to the rather simplistic peak control
OmniaONE Multicast - Use and Operation Manual – Version 0.90

and bandwidth limiting methods that were required for analog broadcasting, as well as for the signal
normalization techniques used in recording and mastering.
Audio codecs on the other hand are moving targets - each codec algorithm has its own set of
artifacts. So not only does the sonic quality vary depending on the algorithm and bitrate used, but
more importantly they vary in their ability to mask their own coding action. This is why we call it a
‘moving target’, and is why conventional audio processors fall short in a coded audio environment
and can actually make coding artifacts worse due to their inability to adapt appropriately to the
changing operation of the codec as the program content changes.
Prior art in audio dynamics processing could only address some of the challenges of provisioning
audio for coding. This hurdle existed because the codec adapts to the incoming program (so as to
generate the least amount of output data representing the input audio) causing the sonic artifacts
generated by the process to continually change. Unless the audio processor can predict these
changing characteristics of the codec, it can’t possibly create output audio that is perfectly tailored
for the coding process.
Conventional processors utilize rather simplistic high frequency limiters and fixed low pass filtering
that does not change with the program material. When these less intelligent processors feed a codec
the audio might sound acceptable one moment and offensive the next. Because they cannot “know”
what the codec will do next, the result is over-compensated, dull and lifeless audio… audio that still
contains objectionable codec-generated artifacts!
OmniaONE Multicast and HD® Radio
The advent of HD RadioR has introduced the capability to transmit multiple program streams, or
“Multicast”, within a single 96kbps digital broadcast data channel. To facilitate this, multicast relies
on the use of codecs with comparatively low bitrates. A broadcaster can choose to transmit a number
of multicast channels and select the bitrate for each one. However, the more multicast channels there
are, the lower the bitrate each channel must have in order for them to all fit within the total available
bandwidth.
In the very near future, many low bitrate multicast audio channels might exist. To achieve maximum
sound quality, the kind that attracts and holds listeners, those channels will need specialized
dynamics processing capable of creating great sound regardless of program content and bitrate.
They will need Sensus®.
OmniaONE Multicast was designed from the ground up for provisioning audio for codecs operating
at these low bitrates. With Sensus®, the innovative algorithm inside OmniaONE Multicast, it is now
possible to have consistently high audio quality with a minimum of codec-induced artifacts.
OmniaONE Multicast creates highly listenable audio lacking the dull, muffled, ‘swirley’ sound
usually associated with codecs operated at extremely low bitrates.

So… what’s so smart about Sensus®?
The fact is, Sensus® is smart. In real time it predicts program content that will be troublesome for
the codec, and by modifying it’s own algorithms can make appropriate changes to the program
material before it ever reaches the codec!1 The result is consistently high audio quality through a
codec-based system, even at very low (18kbps – 21kbps) bitrates.
The human voice is very difficult to code at low bitrates without quality and intelligibility suffering.
But OmniaONE Multicast with Sensus® can generate clean, smooth, crystal clear audio that’s
consistently great sounding no matter what the codec or bitrate is.
--- Important Note ---
1
It is extremely important to never directly audition the output of the OmniaONE Multicast for
audio quality without the audio being first routed through a codec!
Why?
The processed output of the OmniaONE Multicast has been ‘pre-corrected’ for the characteristics of
the following codec and because of this the audio may contain strange sounding artifacts that will
imitate the ‘inverse’ of what that codec will do. Because of this the audio exiting the OmniaONE
Multicast may be unpleasant to listen to and will certainly be inferior to that which will exit the
codec later on.
In other words, what you hear at the output of the OmniaONE Multicast will bear no relationship to
the audio quality that will be achieved after the audio has passed through the coding process!
Need a corollary to this?
It’s like trying to taste a pizza while still in the grocery store and staring at the raw ingredients that
haven’t been purchased yet.
Thank you for selecting the incredible OmniaONE Multicast Audio Processor. Your continued
patronage and support are appreciated.
Sincerely,
The Omnia Development Team

One each Male and Female XLR to StudioHUB® RJ45 adaptor cables.
AC Power Environment
The OmniaONE subsystem is a DSP-based microcomputer, and therefore requires reasonably clean AC power
environment just as any modern computer system does. And even though the OmniaONE power supply is equipped
with robust AC transient suppression, we recommend that external transient suppression and/or an Uninterruptible
Power Supply (UPS) be employed.
At transmitter sites there can be heavy transients on the power lines as well as significant surges introduced into the
power system by frequent lighting strikes. These are unwelcome power line events and can damage even the most
robust equipment. Therefore you should give the AC power environment and installation practices thorough
consideration before plugging in the OmniaONE (or any other microcomputer-based equipment).
A White Paper by one of our Support Engineers can be found on the Telos Systems website at the URL listed below.
It details proper grounding and contains links to some surge suppression products for both the power mains and the
often-neglected telephone, Ethernet and ISDN line connections that can (and do) conduct powerful surges into the
equipment.

Installation & Connections
Throughout this section reference is made to “software parameters.” These are part of the User Interface, which is
covered in detail in Chapter 2.
Rack Mounting
The OmniaONE requires one RU (1.75" [44.45 mm]) of rack space. Rack mount the unit using four rack screws. If
only two screws are going to be used, they should be in the bottom holes in the Omnia front panel. No other two-
screw mounting arrangement will prevent distortion of the front panel!
Adequate ventilation should be provided, and it is always good engineering practice to allow one blank rack space
immediately above and below the Omnia, especially if equipment generating significant heat is located below the
unit. You may install 1RU (1.75") vented or solid rack panels to fill these spaces.
The processor should be installed into a properly grounded 19" equipment rack. Refer to Chapter X, “OmniaONE
User Tips”, for additional considerations on where to physically locate your processor.
AC Power Connection
OmniaONE utilizes an un-switched EMI-filtered IEC power-entry module.
OmniaONE’s automatic voltage–sensing, high-efficiency switching power supply allows it to operate on AC mains
voltages from 100 to 240 VAC and from source frequencies of either 50 or 60 Hz.
In the USA, plug the provided IEC type AC power cord into the unit and then into a grounded AC outlet.
Outside of the USA you must use the appropriate power cord that complies with local electrical regulations.
After power is first applied to the OmniaONE, the LCD screen, the “in” and “out” LED’s and the rightmost
segments of the LED bargraph meters should light. After about 20 seconds the LCD screen should show
“OmniaONE Multicast” and at about 30 seconds the Main Menu should appear. Once the Main Menu appears the
unit is ready for use.

Analog Audio Inputs and Outputs
Balanced XLR-type connectors are used as input connectors for the analog audio. Both analog and digital input
sources may be connected simultaneously, however, only the input source that has been selected is active.
Analog/Digital/Livewire Input source selection is done through the “Source” software parameter setting in the
Input/Output / Input Menu.

A Note About Relative Phase:
If the relative phase of your installation (including the OmniaONE) differs from that of your existing system, your
announcers may feel that they sound “weird” in their headphones. If this occurs, then the relative phase of the
processor is 180 degrees from what your air talent is used to. To remedy this, you can either reverse the polarity of
both of the analog inputs or simply change the Invert setting to [Both] in the Input submenu of the Input/Output
menu.

AES/EBU Digital Input, AES/EBU External Sync Input, and AES/EBU Output
The digital AES/EBU (AES-3) inputs (IN and EXT. SYNC) use industry-familiar RJ-45 connectors and utilize the
StudioHUB+ wiring standard1. They accept any sampling rate between 32kHz and 96kHz. No user adjustment of the
sample rate is necessary on the AES-3 input as a high-quality digital sample rate converter is built in. Individual
channel gain and level setting for both analog and digital domains is done using the Input Gain software parameter
settings in the Input Menu. There is one AES-3 output on a standard RJ-45 connector that provides an output at
selectable sampling rates.
Note: The analog and digital outputs are active simultaneously.
For your convenience, a pair of XLR adaptor cables are supplied with the unit. The male XLR lead with the
GREEN shrink tubing is used for AES OUT. The male XLR lead with the RED shrink tubing is not used.
The female XLR lead with the GREEN shrink tubing is used for AES IN and the female XLR lead with the RED
shrink tubing is used for AES EXTERNAL SYNC IN.
Ethernet Connection
The RJ-45 10BaseT / 100BaseT Ethernet / Livewire I/O jack can be used simultaneously for both TCP/IP based
remote control of your OmniaONE and audio input/output to your existing Livewire network.
Please note that the Remote Control and Livewire functionality are not yet implemented in the current software but
will be available with a free downloadable software update. Please check the Omnia website for new software

RS-232 Modem Connection (DB-9F)
This DB9-female connector can be used to connect an external dialup modem for a bi-directional computer remote
control connection.1
NOTE: This connector is for a remote control external modem connection only. Please see Appendix B for
information on how to use a terminal program along with an internal RS-232 connector for troubleshooting
purposes.
RS-232 Modem Port
NOTE: You must use a standard straight-through serial cable and not a null modem cable when connecting the RS-
232 connector of the Omnia and the external modem. Typically this would be 9-pin to 25-pin cable. (External
modems traditionally have 25 pin connectors in "DCE" configuration. The OmniaONE has a 9 pin in "DTE"
configuration, so the standard 9-pin to 25-pin cable will work).
1 The setup and operation of the Omnia Remote Control application is covered in detail in Appendix C.
Please note that the Remote Control functionality is not yet implemented in the current software but will be

General Purpose Interface (GPI) (DB-9M)
This DB9-male connector serves as a four-input, optoisolated interface to the Omnia's internal trigger script
functions. Four of the pins are “trigger” inputs, four are “ground” and the remaining pin is +5V power. The trigger
inputs can be used to dynamically alter the OmniaONE’s operation in response to logic transitions on the interface
connection. Virtually any parameter of the Omnia can be controlled using the Trigger Scripts.
The Trigger Script Interface Editor is a standard component of the OmniaONE Remote Control application and is
covered in detail in Appendix C.
Please note that the Remote Control and Trigger Script functionality are not yet implemented in the current software
but will be available with a free downloadable software update. Please check the Omnia website for new software

Powering Up
Now you are ready to power up the OmniaONE for the first time.
Connect AC power to the unit using the appropriate supplied power cable for your location.
(There is no power switch!)
When the OmniaONE is first powered on, audio will appear at the analog audio outputs in approximately ten
seconds. The AES/EBU outputs also become usable at this time however full initialization of the AES/EBU ports is
not complete for several more seconds and a small audio glitch may be heard when the final sample rate converter
initialization is complete. Once the boot process is finished the following Main Menu will appear:

Chapter-2: Getting To Know Your OmniaONE
The OmniaONE User Interface
Now that your OmniaONE is rack-mounted, connected to a program audio source, and turned on, you’re ready to
learn how to operate it! This chapter covers the Front Panel User Interface, your window into the OmniaONE
processor.
A front panel jog-wheel with integral push switch, LED bargraph peak-reading level meters and a backlit LCD
display that is switchable between menu and AGC/Limiter metering screens make up the primary OmniaONE User
Interface. The front panel menu access may be password protected to prevent unauthorized tampering with
processing or presets.

Level Meters
Headphone Level Control
A standard ¼" TRS stereo headphone jack is located at the left side of the front panel and allows the processed
signal to be monitored. The Headphone volume level control is physically located to the right of the headphone jack.
The headphone amplifier itself is a high-headroom design and is driven by its own high quality D/A converter that is
independent of the analog XLR outputs. Therefore level changes in either output will not affect the other.
Level Meters & Processing Bargraphs
The top two of the three horizontal meters show digital sample-accurate peak representations of the left and right
channel input or output levels. Whether these bargraphs are displaying Input or Output levels is selectable from
within the Input/Output menu. A front panel indicator confirms which level view has been selected, Input or Output.
The bottom horizontal meter (marked “comp / aux”) is not currently used in the Multicast.

Audio I/O Level Display
Either input or output levels can be displayed. The highest LED illuminated indicates digital sample-accurate peak
signal levels. The meters are calibrated in decibels below full scale digital (0 dBFS), which is the absolute maximum
level in the digital domain.
Audio I/O Level Display
Processing Meter Display
In “Meter Display” Mode the vertical bargraphs show all of the processing activity of the AGC and Limiter sections
within the OmniaONE. If the menu is currently displayed on the OmniaONE’s LCD screen, press and hold the jog-
wheel for two seconds and the processing meter display should appear as shown below.
To return to the menu display mode simply click the jog wheel once. (See “Using the Jog Wheel” on the next Page)
Notes: For any meter, a change from a solid bar to a checkerboard pattern indicates a “gated” condition in that band.
The wideband AGC and four-band AGCs will recover to a resting gain setting which coincides with the
RTZ (Return To Zero) levels set for each band.
The bargraph for the final limiter (F) may not indicate any G/R, but it is operating. This is due to the very
fast peak timing that is employed, which may be occurring faster than the screen is updated.

Using the Jog Wheel
The main user control for the OmniaONE is the easy to use jog wheel with its integral push-switch. Using the
control is both intuitive and efficient, making it easy to navigate the menu structure of the OmniaONE. Processing
changes and system adjustments can be quickly made with ease without having to remember multiple controls, their
positions, and what they do in each menu. The behavior of the OmniaONE's menu system is consistent across pages
and is easy to learn. We believe that you will quickly become comfortable with how it works, and appreciate its
simplicity.
Clockwise rotation moves the highlighting in a menu downward and increases a value when editing parameters.
Counterclockwise rotation moves the highlighting in a menu upward and decreases a value when editing parameters.
Pressing inward on the jog-wheel activates the Enter, Return or Select button function as follows:
Pressing the jog-wheel inward once (also called “clicking”) selects the highlighted menu item or accepts the current
parameter value. Think of it as a vertical mouse button.
Pressing and holding the jog-wheel in for two seconds will switch the LCD screen to a display of the processing
meters so that the gain-reduction activity of the AGC and Limiter sections can be monitored.
Clicking once when the metering screen is displayed will return the display to the menu screen.

Main Menu
The OmniaONE menu system has been designed to be intuitive and simple to use. Most operating parameters are
found under one of the menu headings and sub-headings, allowing adjustments to be made quickly and with ease.
Rotating the jog-wheel sequentially highlights each menu item in turn.
When the jog wheel is pressed inward (clicked) while a menu item is highlighted it will open that item’s submenu.
Similar behavior occurs when selections are made within the various submenus.
To return to the previous level, rotate the jog wheel clockwise until <-Exit is highlighted and then press the jog
wheel inward. (Click) This will return you to the next highest level in the menu structure. NOTE: Some of the
longer menus have an <-Exit option at the top of the menu as well as at the bottom.
The OmniaONE Main Menu offers five selections:

User Interface Tutorial – Input Source Selection and Peak Level Setting
The following two exercises are a useful introduction to the user interface. Start from the Main Menu (as displayed
when the unit is first turned on).
The first exercise changes a parameter selection (the Input Source selection):
¾
¾
Rotate the jog-wheel to highlight Input/Output.
Click the jog-wheel (push on the wheel once until a click is felt and release) to bring up the Input/Output
menu.

The factory default selection for Input Source is Analog. To change the input selection to AES/EBU digital,
rotate the jog-wheel until [AES/EBU] is displayed and click. If you are using the analog inputs, rotate the
jog wheel to display [Analog] and click to reselect the analog inputs.
To return to the top level of the Main Menu, rotate the jog-wheel to highlight <-EXIT and click. Repeat
until the top level (Main Menu) is reached. NOTE: Many of the OmniaONE’s menus have an <-EXIT
selection at both the top and bottom of the menu.
The next exercise adjusts a parameter that uses a value (the analog master input level setting):
¾The Main Menu display should still be showing on the LCD screen. If not, click the jog-wheel to display it.
¾Highlight Input/Output and click.
¾Highlight Mtr Select, click, rotate the jog wheel until [Input] is displayed and click. This sets the first 2 LED
meters to monitor the Left and Right channel input levels.
¾Rotate the jog wheel clockwise to highlight Input and click.
¾Rotate the jog wheel to highlight Anlg Level and click the jog-wheel to select the control.
¾Rotate the jog-wheel CW to increase the input level. Rotate the jog-wheel CCW to decrease the input level.
This control adjusts both channels together in precise 0.5 dB steps. The gain in dB is shown to the right of the
“control.” Watch the Left and Right channel LED meters while adjusting per the following paragraph below.
Proper Setting of Input Levels
With normal program audio levels applied, a correct input level setting will result in peak indications on the L & R
LED meters achieving between –15 and –12 dBFS or a little higher. This gain setting corresponds to system
headroom of about 12 –15 dB. You may adjust the input level for more headroom if you wish (by lowering the
levels to increase headroom). Setting the input level for higher meter indications (less headroom) is strongly
discouraged unless there is another level-control device prior to the OmniaONE that will keep the input levels from
reaching the maximum digital level of 0 dBFS.
¾Once the desired level setting is reached, click the jog-wheel to accept that value. This returns the jog-wheel
to Select Mode.
¾You may highlight and click Right Trim to adjust its gain separately from the left channel if the input source
is not well balanced. In this mode the right channel gain can be adjusted over a range of plus and minus 3 dB
relative to the gain setting of the left channel.
¾To return to the top level of the Main Menu, rotate the jog-wheel to highlight <-Exit and click. Repeat until
the top level (Main Menu) is reached.
All of the OmniaONE’s software parameters are set in a similar fashion using the jog-wheel to scroll through menu
items. Clicking a highlighted item selects it; when that item is a control, the jog-wheel adjusts the value or level.
Clicking accepts the value or level and returns the jog-wheel to Select Mode.
Note: Altering any processing or gain parameter will instantly be reflected in a change in the OmniaONE’s output
characteristics because adjustments occur in real time. Therefore any adjustments you make will be instantly heard
as they occur.

Chapter-3: Getting The Sound You Want
In general, applications requiring audio processing prior to a codec don’t rely heavily on absolute loudness for their
overall success. Loudness is still important of course – you do want to be heard – but it is not the most important
thing. It has been well established that codecs generally do not like extremely processed audio applied to their inputs
because with very dense audio there are fewer opportunities to hide coding artifacts (these opportunities to hide
coding action are commonly referred to as codec entropy).
If you believe that you’re in a density war and you feel a need to react, we can provide some suggestions that should
help. Conversely, if you have the luxury to strive for increased sound quality, we’ve got suggestions for you too!
There will always be a subjective compromise whenever there is a desire to shift the processing priority from the
highest quality setting to those generating the highest loudness.
OmniaONE Multicast has been designed to minimize the trade-offs between quality and loudness, and we
recommend that before starting the process of cranking it up, try to determine beforehand what sonic characteristics
might be lacking.
In many cases it’s not just about increasing the drive to the limiters. Instead, it can be as non-intuitive as creating the
illusion of greater loudness by changing something simple – like a time constant. Sometimes the old adage of less is
more really applies!
Please give the following content some thought as it may assist you in developing an overall fine-tuning plan if you
feel changes beyond our factory presets are justified.
A Word About Density, Clarity, and Intelligibility
Processing for the coded audio world is quite a bit different than what is done for FM-Stereo and AM. There are two
significant differences, and both impact the overall sound of a coded transmission: First, there is no pre-emphasis
network in coded audio. Second, clipping should never be used for peak control.
In conventional broadcast applications the method of clipping that was used contributed substantially to the quality
vs. loudness tradeoff – it was a fairly simple two-way tug of war.
In the coded domain the tradeoff is much different - it becomes a three-way tug of war between quality, loudness,
and audible artifacts. Using the rules for conventional processing will cause trouble in a coded audio environment.
Why? Because Codecs complain. And they complain in the form of nasty and objectionable artifacts when harmonic
or intermodulation (IMD) distortion is presented to their input. In fact, dynamic peak limiters employing extremely
fast time constants (which generates a form of program-dependent IMD) can easily cause serious trouble for a
codec.
Quality Versus Density
The primary trade-off between quality and artifacts will be located within the processor’s limiter sections. With
increased depth of limiting, intermodulation distortion increases and the ‘fast’ activity of the limiters causes the
audio to sound “tight” or “squashed”. If limiting is taken to the extreme, the sound can be perceived as “pumping,”
“breathing,” “dense,” or “mushy.” It can even induce exaggerated “swish/swirl” artifacts from the codec.
Please remember that the core objective of the OmniaONE Multicast product is maximum intelligibility at low
bitrates and processing that creates heavy density can completely mask that effort. A codec provisioning processor is
in quite a different role than a conventional on-air processor. It is far more of a tool than a weapon.

The following sections are provided to assist you in designing the personality of your sound. As we said earlier,
there is no precise recipe for setting up audio processing because each application is different. However there are a
few basics that we can share with you that can help get you to where you want to go. Setting up processing for the
absolute best end product usually requires a concerted effort, some extended periods of critical listening, and making
a few intelligently chosen and subtle changes over time. It will be time and effort well spent, and all you need to
know up front is that you must:
¾
¾
¾
¾
Know your goals (have a plan).
Take your time.
Always adjust deliberately and methodically.
Listen critically before making more adjustments.
Increasing Density/Loudness
Try to resist the temptation to crank up the aggressive processing sections. They will definitely add loudness but
usually at the cost of quality and intelligibility. Many times, just building a bit more RMS energy in the AGC
sections will do the trick.
The following are some suggestions on where to begin to make changes. For best results you should try them in the
order we have listed below.
Increasing loudness can be accomplished in five ways:
1. Alter the following parameters in the AGC:
ƒ
ƒ
Increase the Drive to the AGC sections.
Increase the Release settings to make the bands operate faster.
2. Modify the Multiband Limiter sections:
ƒ
ƒ
Increase the Drive to the Limiter section.
Increase the Release settings to make the bands operate faster.
Note that slowing the Attack time by using a lower setting can help make things sound more natural
when faster Release times are used. But be careful not to allow too many fast transients through to the
final limiter section.
3. Set the Hold threshold in each band to a lower value.
4. A combination of all of the above (yes, it sounds crazy but it’s true)!
Always resist the temptation to make too many changes at once because it then becomes difficult to determine why,
or why not, an adjustment made the change you hear. It is better to make small adjustments to a small number of
controls at a time, and then listen to the result with a wide variety of program material. Once you have satisfactory
results in one area (like overall density) you can then move the focus to the next area that you feel needs more
tweaking.
Don’t be afraid to experiment with different styles of processing! Our presets are good starting points and are not
restricted to any particular format because of their name!

Some users prefer their processing to be perceptibly loud but very dynamic. While this may not result in the loudest
sound, it gives the illusion of competitive loudness while still retaining a lot of detail and clarity. To achieve this
sound you should target most adjustments to the Limiter sections, and avoid heavy use of the Final Limiter and fast
settings in the AGC sections. Using very fast attack and release times in the multi-band limiters - without pushing
them beyond 5dB or so of gain reduction - keeps IM distortion to a minimum and generates higher RMS levels. This
translates into higher perceived loudness.
On the other hand, using larger amounts of drive to the multi-band limiters, along with faster release times will
generate far more consistency and density. Increases in final limiting depth (more drive) will further add to this. The
end effect is that the audio is now consistently loud - at all times.
The drawback to this kind of sound is that when taken to extremes, the excessive density can cause listener fatigue
and add additional coding artifacts. While OmniaONE Multicast is designed to minimize listener fatigue, when
adjusted to do so it is capable of generating large amounts of density that could eventually lead to listener fatigue.
Adding More Detail—When Loudness Isn’t The Last Word
Now that we’ve “squished the grape,” lets look at what it takes to undo a signal that is being too heavily processed.
Basically, we’ll just be reversing the procedures listed above and in this order:
1. Reduce the Drive to the Final Limiter.
2. Back off on the influence of the Limiter stages:
• Reduce the amount of Drive.
• Lower the Release settings in each band to slow down recovery.
• Raise the threshold of the Hold function.
3. Ease up on the Wideband-AGC sections:
• Reduce the Drive to the Wideband-AGC.
• Lower the Release setting to cause it to operate slower.
Backing off the limiting sections first will allow the processing to still retain a level of loudness while restoring
punch and quality. Start with reducing the Final Limiter amount in 0.5 dB steps. It’s surprising how much detail can
be restored from such a small change. Generally, a change in the Final Limiter drive will have the most noticeable
effect on quality, but it will also affect the relative loudness level, too. You’ll need to find a “happy medium” that’s
right for your application.
Equalization (EQ) Changes
Tailoring the shape of the overall audio spectrum can be done in four different ways:
¾
Adjusting the Drive to the individual bands from within the XOver menu, which sets the input
levels to the multi-band AGC sections.
¾
¾
¾
Changing the relative amount of Drive to the multi-band limiters.
Adjusting one or more bands to have faster release times than the others.
Adjusting the settings within the final Mixer.
All four options will provide a noticeable change in EQ and each will have a different character. We suggest you use
the first two listed options before trying others. In each case the EQ change you make is followed by a dynamically
controlled stage, so the subsequent AGC or Limiter will counter any excessive EQ adjustments.
OmniaONE Multicast - Use and Operation Manual – Version 0.90
29
Download from Www.Somanuals.com. All Manuals Search And Download.
The last option, adjusting the Mixer, is designed to provide a final minor trim to the audio spectrum. Since this stage
is after all of the dynamic multi-band AGC and Peak Limiting, a radical change in level in the Mixer could result in
excessive look-ahead final limiting in that band’s frequency range. We suggest that any changes implemented here
be limited to about 0.5 dB to 0.7 dB of boost maximum. Alternately, a decrease in mix levels can be done in any
desired amount and without fear of final limiter overdrive.
Thunder Bass
OmniaONE Multicast has the power to shake the walls with low end! If your source material has it, OmniaONE
Multicast can expose that deep bass and do it with muscle! Tailoring Thunder Bass for more dominance is simple,
and is done by adjusting the following parameters and in the order listed:
1. Increase the amount of Bass boost in the Enhance section.
2. Increase the Drive to Low Frequency Limiter.
3. Increase the Release setting in the Low Frequency Limiter.
Just as in the section on ‘overdoing’ processing, again moderation is the key. If all of the above changes are made in
unison there is a possibility of severe low frequency buildup. This would unbalance the audio spectrum and produce
the illusion of “lost” presence and high frequencies.
Generally, an increase in the Bass boost alone will provide a sufficient enhancement to the low end. Bass
adjustments should typically be done after selecting the preset you wish to use and the low pass filter that is
appropriate for the codec to be used.
Adjusting processing for coded audio is different than conventional radio. While many of the dynamics functions are
the same, i.e. compression, limiting, EQ, etc, please consider that the audio processor is a tool to improve the
performance of the codec. This is especially true at lower bitrates. When making processing adjustments, try to
avoid building too much density in the presence and high frequency ranges. Density in this spectra cause codec
efficiency to become reduced and artifacts increased.
Even though Sensus® technology is applied downstream from the main processing and will improve system
performance, remember that the processor is a sum of its collective dynamics parts and the result will be based on
the cumulative effect of all of the settings. When adjustments are being made pay particular attention to program
content that segues from music to voice and back again. If everything is working properly the vocal quality should
not change due to the coding process. If this is noticed, try reducing the Sensus® function value by one adjustment
click and then reevaluate.

Chapter-4: Main Menu Selections
This section presents an overview of the five Main Menu items, (Preset:, Processing, Input/Output,
Administrative and Lock Front Panel) their submenus (if any), and details about each of the adjustable controls
within.
Preset
OmniaONE is equipped with a selection of factory presets that can be used to instantly configure the processing for
common applications. The currently loaded preset is displayed to the right of Preset: on the top line of the Main
Menu.
Highlighting Preset: and clicking the jog wheel (see Using the Jog Wheel on Pg. 24) will open the Preset menu.
Rotating the jog wheel will scroll through all of the factory presets as well as any user presets that have been stored
within the unit’s non-volatile memory. The currently loaded preset will appear with square brackets around it.
Clicking the jog wheel will load the displayed preset into the OmniaONE, instantly setting the various processing
parameters.
To exit the Preset menu without loading a preset, rotate the jog wheel clockwise until *cancel* is displayed and
click.
In the Multicast, there are two groups of factory presets, Music and Talk. Within each group, there are presets for
each of four bitrates commonly used by codecs following the OmniaONE: 24, 32, 48 and 64 kbps.
By starting with one of the factory presets (usually the one named closest to the primary programming and bitrate to
be used on the channel the OmniaONE Multicast is processing) and then altering it using the controls in the
Processing menu, you may change the sound of a preset and then save it with your changes as a user preset for
either immediate use or later recall.
By alternately loading different presets you may compare the sound between them.
Here in the Preset: menu, you may select and load presets to use, but not save, delete, or rename them. Those
operations may be accomplished from within the Processing menu.
Processing
Highlighting and clicking Processing from the main menu opens up the Processing submenu that contains these
options: Adjust Processing, Save Preset, Delete Preset, Rename Preset and <-Exit. This is where the sound of the
OmniaONE can be fine-tuned and customized. Once customized, this is also where your user presets are saved,
deleted and renamed. Each submenu in the Adjust Processing menu can be highlighted, clicked to open, and the
individual controls within can be adjusted to individual taste.
Since you cannot build a preset from scratch, a factory preset must be used as a starting point for creating your
“signature sound.” Each processor parameter may be adjusted to taste as required. Once the processing is adjusted,
the Save Preset function is used to store your changes as a new user preset to non-volatile internal memory.
Using the Delete Preset and Rename Preset options, existing user presets may be deleted from memory or renamed
as needed. The original factory presets can never be deleted or renamed.
We will discuss the Save, Delete, Rename and <-Exit options first before delving into the details of the Adjust
Processing menu.

Save Preset
This option saves any changes you have made to the currently running preset into the OmniaONE’s non-volatile
memory. Changes can be saved over an existing user preset (without renaming it) or as a new user preset with a new
name. You may not save a factory preset over itself with the same name and attempting this will generate the error
message: “Cannot overwrite factory preset. Save preset with new name.”
Presets can contain up to 10 characters.
To save your changes proceed as follows:
Highlight Save Preset and click. “Name” will be highlighted and the Name field will automatically display the
existing preset name. If you wish to overwrite this existing preset with your changes, just rotate the jog wheel
clockwise to highlight the Save button and click. Your changes will be saved to the existing preset.
If instead, you wish to save your changes as a new user preset with a different name, click the jog wheel while
“Name” is highlighted and the editing cursor will appear, highlighting the first character of the existing preset name.
This is “select” mode.
At this point you can scroll left and right through the text by rotating the jog wheel knob. Be careful not to scroll
clockwise past the blank space just after the last character of the preset name or “select” mode will be cancelled. If
this happens, simply rotate the knob counter-clockwise until “Name” is highlighted and click to re-enter “select”
mode.
When you reach the character you want to edit, click. This puts the cursor in “edit” mode. You can now change that
character by scrolling through the character list with the knob. When the desired character is found, click. This will
return the cursor to “select” mode and you can again turn the knob to select the next character to edit.
-To delete a character... Select the character to be deleted, click, choose the " < " symbol and click again to delete
that character. Characters can only be deleted one at a time.
-To insert a character between 2 existing characters... Select the character just after where the new character is to be
inserted, click, choose the " ^ " symbol and click again. The new character appears. Now rotate the knob to select the
desired character for it and click to accept. (Note that this inserts a new character before the one selected, and keeps
the originally selected character intact as what it was before choosing "^")
When you are finished, simply rotate the knob clockwise (with the cursor in “select” mode) until the Save button is
highlighted and click to save the preset. Your new user preset will now appear in the Preset: menu.
-To cancel at any time without saving… With the cursor in “select” mode, rotate the knob clockwise until Cancel is
highlighted and click.
Delete Preset
This option allows a preset to be deleted. You may never delete a factory preset. An error message will be generated
if you attempt to do so. You may delete the last preset that was loaded. The loaded settings, along with any
changes, will continue to “live on” as the current settings, but cannot be recalled again until they are saved.
To delete a user preset highlight Delete Preset and click. Rotate the jog wheel to display the preset to be deleted.
Click the jog wheel and that preset will be instantly deleted. Warning: There is no delete confirmation dialog!
If you wish to exit without deleting a preset, rotate the jog wheel clockwise until *cancel* is displayed in the preset
list and click.

Rename Preset
A preset in the list of stored user presets can be renamed at any time. Factory presets cannot be renamed.
To rename a user preset highlight Rename Preset and click. Rotate the jog wheel to display the preset to be
renamed and click.
Edit the preset name as described above in the Save Preset section.
To exit without renaming the preset, rotate the jog wheel until *cancel* is displayed and click.
<-Exit
Click on this option to return to the Main Menu.
Adjust Processing
This submenu allows changes to be made in any of the OmniaONE’s several dozen processing parameters. These
adjustments alter the sound and texture of the audio. Increasing any setting will lead to more aggressive processing.
For example, a higher drive setting adds more gain into the dynamics section, a higher attack or release setting
means a faster time constant, a higher gate threshold setting means more gating will occur, and a higher (farther to
the right on the control) setting for a filter means more filtering is occurring (so the lowest frequency settings for a
low pass filter are farthest to the right on the control).
Depending on the type of control adjusted and its range, the changes you make can affect the sound in subtle or
extreme ways. Our advice is to make a limited number of changes at a time, make those changes in small
increments, and then listen to the results for a period of time before making any further adjustments. Keep in mind
that should you get “lost” you can always go back to where you started by simply recalling the preset that you
started with. The factory presets cannot be overwritten.
<-Exit
Click on this option to return to the Processing submenu.
Pre-processing
HPF (High Pass Filter)
The high pass filter allows you to remove subsonic energy from the input audio prior to further
processing. In so doing, intermodulation distortion performance of the processor and the audio
path following it are improved, and processing resources are not wasted processing inaudible
sounds that have no acoustically relevant information.
Phase Rot (Phase Rotator)
The phase rotator improves waveform symmetry for program material that is highly asymmetrical
in nature. Examples of such programming are the human voice, and sources with non-sinusoidal
waveforms such as certain string and wind instruments, as well as certain sounds created by
electronic synthesizers. By removing waveform asymmetry from the input program material,
cleaner processing results because any limiting that occurs is able to work equally on both positive
and negative excursions of the audio waveform.
Wideband AGC
OmniaONE Multicast - Use and Operation Manual – Version 0.90
33
Download from Www.Somanuals.com. All Manuals Search And Download.
WB AGC (Bypass, Engage)
The wideband Automatic Gain Control (AGC) stage can be bypassed if desired, although more
consistency is achieved when this stage is used.
AGC Drv (AGC Drive)
This control adjusts the amount of drive to the wideband AGC stage. Increasing the drive causes
deeper compression to be achieved, and deeper compression allows quieter passages in the input
audio to be raised further than if lesser drive (and less compression) was used.
AGC Att (AGC Attack)
The attack control adjusts how fast the AGC responds to sudden increases in audio level, and
higher numbers equate to faster response times. Faster attack times reduce the transient nature of
the input audio, while slower attack times improve it. Extremely slow attack times must be used
with caution because allowances must be made in later stages to not overload them during the time
when the broadband AGC is adjusting the level downwards.
AGC Rls (AGC Release)
The release control adjusts how fast the AGC recovers from periods of more gain reduction
when the input audio levels fall. Faster release times (higher numbers) result in a more dense
sound. Even though the Omnia uses program controlled release algorithms, setting the control for
extremely fast release times can result in ‘pumping’.
Gt Thresh (Gate Threshold)
When the input audio falls below a certain level, the gain control action of the AGC stage is
“frozen” by the gate. The level at which this freeze, or hold takes place is controlled by the setting
of the Gate Threshold control. Higher numbers cause the gate to activate at higher audio levels. In
most applications this control should be adjusted to cause gating action to occur when the input
audio falls about 20dB below nominal. The action of gate also prevents noise rush up during
periods of no audio or during pauses in speech.
RTZ Speed (Return To Zero Speed)
RTZ stands for Return To Zero. What RTZ does is return the gain of the WB AGC section to an
internally determined amount of gain reduction in the absence of audio. RTZ speed controls how
fast this adjustment takes place – i.e., how long it takes the AGC to move to the target RTZ
platform level.

Enhancers
Deep Bass
Adds ‘girth’ to the audio by enhancing very low frequencies such as kick drum fundamentals or
very low bass notes that may be present in the input audio program.
Phat Bass
An Omnia exclusive, Phat Bass adds harmonic overtones to the lower bass frequencies. The
addition of these overtones causes small speakers to seem to produce bass response that they are

not actually capable of producing because the human brain equates the presence of low frequency
harmonics to the missing fundamentals that the small speaker is unable to reproduce. On systems
with larger speakers, the effect of Phat Bass becomes subtler because the extended frequency
response of those systems allows the fundamentals of the low notes to be heard, masking the
added harmonics contributed by Phat Bass. Be careful though, too much Phat Bass boost can lead
to excessive gain reduction in the lower AGC bands and may cause muddiness with certain
program material. A little goes a long way.

Xover (Crossover)
Low Drive
Adjusts the amount of gain reduction in the Low Band AGC. Higher numbers result in more drive
and because of the increased compression, a more consistent output from the band.
Mid Drive
Adjusts the amount of gain reduction in the Mid Band AGC. Higher numbers result in more drive
and because of the increased compression, a more consistent output from the band.
Pres Drive
Adjusts the amount of gain reduction in the Presence Band AGC. Higher numbers result in more
drive and because of the increased compression, a more consistent output from the band.
Hi Drive
Adjusts the amount of gain reduction in the High Band AGC. Higher numbers result in more drive
and because of the increased compression, a more consistent output from the band.
<-Exit
Click on this option to return to the Adjust Processing submenu.
Low Band AGC
Attack
The attack control adjusts how fast the AGC responds to sudden increases in audio level, and
higher numbers equate to faster response times. Faster attack times reduce the transient nature of
the input audio, while slower attack times improve it. Extremely slow attack times must be used
with caution because allowances must be made in later stages to not overload them during the time
when the broadband AGC is adjusting the level downwards. Likewise, extremely fast attack times
(especially when combined with very slow release times) can “punch holes” or overreact to the
band of audio being processed.
Release
OmniaONE Multicast - Use and Operation Manual – Version 0.90
35
Download from Www.Somanuals.com. All Manuals Search And Download.
The release control adjusts how fast the AGC recovers from periods of more gain reduction
when the input audio levels fall. Faster release times (higher numbers) result in a more dense
sound. Even though the Omnia uses program controlled release algorithms, setting the control for
extremely fast release times can result in ‘pumping’.
Gt Thresh (Gate Threshold)
When the input audio falls below a certain level, the gain control action of the AGC stage is
“frozen” by the gate. The level at which this freeze, or hold takes place is controlled by the setting
of the Gate Threshold control. Higher numbers cause the gate to activate at higher audio levels. In
most applications this control should be adjusted to cause gating action to occur when the input
audio falls about 20dB below nominal. The action of gate also prevents noise rush up during
periods of no audio or during pauses in speech.
RTZ Speed (Return To Zero Speed)
RTZ stands for Return To Zero. What RTZ does is return the gain of the AGC band to the selected
amount of gain reduction (See RTZ Level below) in the absence of audio. RTZ speed controls
how fast this adjustment takes place – i.e., how long it takes the AGC to move to the target RTZ
level.
RTZ Lvl (Return To Zero Level)
This control adjusts the gain level to be achieved by the AGC section during lapses in audio. The
primary purpose of RTZ is to prevent the AGC from increasing the gain unnecessarily during
lapses in audio, which would result in an increase in noise level.

Low Band Limiter
LFLim Drv (Low Frequency Limiter Drive)
Adjusts the drive level to the individual Limiter band. Used when you desire more or less density
in a specific band. These Limiter Drive controls can also be used as secondary dynamic EQ
controls after the Drive controls in the AGC Xover.
LFLim Att (Low Frequency Limiter Attack)
OmniaONE Multicast - Use and Operation Manual – Version 0.90
36
Download from Www.Somanuals.com. All Manuals Search And Download.
The attack control adjusts how fast the limiter responds to sudden increases in audio level, and
higher numbers equate to faster response times. Faster attack times reduce the transient nature of
the input audio, while slower attack times improve it. Extremely slow attack times must be used
with caution because allowances must be made in the following final limiter stage so as not to
overload it during the time when the limiter is adjusting the level downwards.
LFLim Rls (Low Frequency Limiter Release)
The release control adjusts how fast the limiter recovers from periods of more gain reduction
when the input audio levels fall. Faster release times (higher numbers) result in a more dense
sound. Even though the Omnia uses program controlled release algorithms, setting the control for
extremely fast release times can result in ‘pumping’ as well as extremely dense-sounding
(fatiguing) audio.
LFLim Hold (Low Frequency Limiter Hold Threshold)
During operation of the limiter, the algorithm is watching for very small decreases in audio level,
such as what occurs right after a sudden peak. When this occurs, the limiter release is temporarily
stopped. The result is a drastic reduction in intermodulation distortion and a more open sound,
even though the audio is still quite dense. The level at which the hold takes place is controlled by
the setting of the hold Thresh control. Higher numbers cause the hold to activate at higher audio
levels. The action of limiter hold also works in conjunction with the preceding AGC gates to
reduce noise rush up during periods of no audio or pauses in speech.

Sensus®
Sen Freq (Sensus® Frequency)
This sets the range where the SENSUS® function begins its magic. For example, a setting of
5kHz will program the SENSUS® algorithm to focus on frequencies of 5kHz and higher. You
should start with the 13kHz setting, and then select lower frequency settings until any coding
artifacts are tamed. There are 8 available adjustment frequencies between 13kHz and 1kHz.
Sen Level (Sensus® Level)
Sets the amount of codec conditioning to be applied to the audio. Increasing the setting adds more
SENSUS® control. Extreme settings -- those high enough to cause noticeable dulling of the
program material -- are unnecessary and will not further improve the audio quality through the
codec.
Ster Link (Stereo Link)
Under most operating modes, this can be set to Low or OFF. The link control allows dynamic
coupling of the stereo to mono ratio. When set to OFF, the Sensus® function will only affect
mono material, or signals that are common to the Left/Right channels under stereo conditions.
Higher settings of the link adjustment may offer assistance with low bitrates and an inefficient
codec.
NOTE: While the Sensus® Frequency and Sensus® Level controls are “algorithmically”
independent, from the standpoint of a codec they work in tandem to reduce coding artifacts
through a bit reduced system. Always start with the LPF (Low Pass Filter) (see Final Limit) set as
recommended by the table in that section. Then adjust Sensus® Frequency and Sensus® Level
controls until satisfactory results are achieved through the codec.

Final Limit
Drive
The Drive control controls the depth of final limiting. The amount of gain-reduction occurring in
the final limiter can be monitored on the Process metering bargraph screen. Note, however, that
this meter cannot show extremely fast action in the limiter, so your ear must be the final judge.
LPF Freq (Low Pass Filter Frequency)
This is a key control and is used for matching the audio bandwidth of the processed audio to the
bitrate of a following codec. Setting this control to the proper bandwidth for the codec’s settings
will ensure minimal side effects and aliasing distortion products from the codec process. The
available settings are: 4kHz, 6kHz, 8kHz, 10kHz, 13kHz, 16kHz and 22kHz. These are the
frequencies at which the low pass filter reaches a minimum of 100dB of attenuation.
One of the most important features that an audio processor for codec provisioning must have is a
high quality, low overshoot low pass filter after the final peak control stage. OmniaONE Multicast
offers this feature as a low pass output filter that can be set to one of seven stop band frequencies.
Each of the filters possess minimal passband ripple and are phase linear below cutoff. Response in
the filter stop bands is greater than -100dB.
The following chart recommends low pass filter settings that, in our experience, best complement
the AAC+SBR, MP3, and Windows Media (WMA) codecs. They were derived through thousands
of hours of critical listening and we feel they are very good starting points for achieving the best
overall sound although you may use other settings that you feel are more appropriate for your
particular codec application.

Always set the low pass filter frequency so that it is at or below half the sampling frequency of the encoder.
This must be done in order to comply with the Nyquist Theorem1. Doing so will achieve the highest perceived
audio quality.

1
The Nyquist Theorem states that the maximum frequency that may be applied to a sampled data system is one
half the sampling frequency. When signals beyond half the sampling frequency are present, aliasing occurs
which causes the appearance of an inverted spectral image of the audio spectrum to be “folded around” the
lower side of the sampling frequency (it is actually folded symmetrically around both upper and lower
sidebands of the sample frequency, however in professional audio applications only the lower sideband is
usually audible). When this occurs the original signals and the aliases are not separable by any means!

Input/Output
This submenu provides level adjustments for the audio inputs and the absolute peak operating level of the Analog,
AES-3 (AES/EBU) and Livewire outputs. Choices governing the selection of the input audio source (Analog, AES
Digital or Livewire) and signal mode (Stereo or Mono) are also found within these submenus.
These I/O settings are generally “set once and forget” parameters, usually adjusted during initial installation and
then left alone. These I/O settings are not saved with a processing preset but can be saved, loaded, deleted or
renamed as “I/O Configurations” using options available in this submenu.

<-Exit
Click on this option to return to the Input/Output submenu.
Input Src (Input Source)
Allows the selection of Analog or AES/EBU (digital) as the primary input source to the
OmniaONE.
Fover Time (Failover Time)
Failover Time is a feature that when set to a value other than zero (disabled) allows the
OmniaONE to automatically select another input source if the currently selected one fails.
Failover Time is the amount of time that will elapse after the failure of audio before the unit
makes the decision to switch to another input. For instance, if Failover Time is set for seven
seconds and the primary audio source fails, seven seconds later the unit will switch to the
secondary audio input. If, at any time, audio is restored on the primary input (for 1 second,
continuously), the unit will switch back to the primary audio input. It will remain with the
primary input unless another failure is detected.
Fover Src (Failover Source)
Failover Source selects which audio input: Analog or AES/EBU digital will serve as the secondary
audio input. Note that the audio input that is selected under Input Source (above) will always be
the Primary audio input. A source selected under Failover Source will always be the secondary
source.

Invert
Permits audio phase inversion to be performed in the following combinations:
[None] –
[Both] –
No Channel inversion is performed (factory default)
Both left and right channel phase is inverted.
“Both” is typically selected if it sounds “better” to an announcer (monitoring themselves in
headphones using the output of the processing) than “None”. One of the two settings should. The
goal is to make the relative phase of the headphone feed more in phase with the announcer’s own
bone conduction. Once set, this setting should remain the same for all announcers using the same
headphone feed.
[L]

–
–
Only the left channel phase is inverted.
Only the right channel phase is inverted.
These settings are present as a convenience to correct 180-degree stereo phase errors in the input
audio to the processor or in another device after the processor.
Mono Mode
Allows input signal routing to be reconfigured as follows:
[STEREO]
Factory default. Left and Right input channels are routed to the left and right inputs to the
DSP processing chain.
[Mono L]
Configures the DSP processing chain to have both the Left and Right internal channels
fed only from the Left Channel of the input source selected. Note that this selection is
active in all sources selected as Primary and Secondary (Failover) audio sources.
[Mono R]

Appendix B: Troubleshooting/Service/Warranty
Operational problems with the OmniaONE can sometimes be diagnosed using the RS-232 serial port located inside
the top cover of the unit (NOTE: This is not the rear panel “RS-232 MODEM” connector) and a common terminal
communications program. Detailed information about the Omnia's boot-up progress may be observed at this internal
RS-232 port, as well as viewing of any error messages that may be encountered. This chapter explains the various
boot up and error messages that may be encountered while troubleshooting the unit. We'll cover some basic
troubleshooting techniques for isolating possible OmniaONE problems in the field, and also how to obtain help or
repair service from Omnia.
To take complete advantage of this functionality, you only need a standard terminal program for DOS, Windows, or
other operating system. It must be configured for a default baud rate of 19200, no hardware handshaking, and using
a terminal emulation for VT100. At Omnia, we commonly use the Hyperterminal© program that ships with
Microsoft Windows©, but you can use whatever program you are familiar with. Please see the examples below for
how we've set up our connection:
Once these parameters have been entered and saved as a connection profile, they can be used to capture and display
(and print) the output of the OmniaONE’s RS-232 internal serial port during boot up.

Before attempting to make voltage measurements, be forewarned that the power supply heat sinks are connected to
the AC power line. Avoid these areas whenever the AC power cable is attached to the Omnia. Never attempt to
make measurements when the power supply's safety cover is removed.
When reinstalling the top cover, make certain that all thirty screws are replaced, and that they are tightened to a snug
fit. Operating the unit with its cover removed or without all of the retaining screws will void your warranty and may
compromise the ability of the Omnia to operate in high RF environments.
Narrowing down problems
When actually troubleshooting your OmniaONE, try to ascertain some preliminary information first before
embarking on an in-depth problem-solving mission. Take time to carefully consider whether your unit falls into any
of the following states:
1. The unit is totally dead. Is the power on? Is the line cord plugged into an outlet that has AC power? Is there an
audio input level? Is there an audio output level? Is there a power indication? Is the LCD screen blank, scrambled, or
not illuminated? Symptoms like these might indicate a power supply problem. If you wish to examine the power
supply, be aware that it is switching type, and therefore requires a load in order to start up and operate properly.
Voltages measured when the power supply is not connected to the Omnia motherboard may not be correct.
2. The unit has power, but there is no audio output although the processing bargraphs are working. The first
thing to verify is whether the front panel jog-wheel is operational. Verification of front panel operation helps narrow
down where the problem is. Look at the metering display. If there is input audio but no output audio indications, try
cycling the unit’s power. If that doesn’t bring the operation back to normal, then a hardware failure of some sort has
occurred. If you get output levels but have no output audio, verify that the outputs are connected correctly. An
analog output connected to a digital device, or a digital output connected to an analog device won’t pass audio!
Connect the appropriate test generator to the output cables to verify analog/digital audio is making it to the next
device.
The next condition to check is to see if the failure has caused the processing to cease. Using program material, check
to see if the processing bargraphs are operating. If they are, then it’s a good indication that the basic DSP structure is
sound and the system's host processor is working. At this point, it would be a good idea to see if the loss of audio is
confined to only one output port, e.g. the discrete left/right outputs or the AES/EBU output. Check the signal at each
of these locations. If the signal is dead at all three, then this points to a digital audio problem after the dynamic
processing DSP chips. If one of the output sections is not operating, then it can be localized to that specific section.
Note: The discrete left/right outputs are operated from their own specialized Digital to Analog converters.
Therefore, it's possible for one type of output to fail without affecting the other. Likewise, a failure in the AES/EBU
driver section could result in the digital output being dead, while the rest of the system is operational.
3. Unit will not boot.

Appendix C: Remote Control & Software
Update Procedure
Remote Control
Please note that the Remote Control and Trigger Script functionality are not yet implemented in the current software
but will be available with a free downloadable software update. Please check the Omnia website for new software
Trigger Scripts
Please note that the Remote Control and Trigger Script functionality are not yet implemented in the current software
but will be available with a free downloadable software update. Please check the Omnia website for new software
Software Update Procedure
Software updates for the OmniaONE are performed over an Ethernet connection using any standard Web Browser
and an update file downloaded from the Omnia website. The OmniaONE contains two software banks and the new
software is always uploaded to the inactive bank. This is a safeguard against loss of power or other interruption
during the update. In this event, the OmniaONE should still boot into the active bank containing the “old” software
(but it is best to avoid interruptions in any case).
To update the OmniaONE software proceed as follows:
1. Download the OmniaONE software update file (.oup) from the Omnia website at:
http://www.omniaaudio.com/support/updates.htm and save it to a convenient folder on your computer.
2. Make sure your OmniaONE’s Network Configuration settings have been entered appropriately for your
(Livewire) jack to your Ethernet network using a standard Cat.5 cable or directly to a computer using a
Cat.5 crossover cable.
3. Open your browser and connect to the OmniaONE by entering: http://xxx.xxx.x.xxx/ in the browser’s
address bar where the x’s in the example above are replaced with the OmniaONE’s IP address as entered in
Step 2. Once connected you should see the Login screen shown below. Enter the Password (Default is
“omnia” – all lower case) and click on the “Login” button. (Or simply press “Enter”)
4. The Main Menu should appear. Click on the “Firmware Update” option.
5. The “Confirm Firmware Update” screen should appear with the following warning:
OmniaONE Multicast - Use and Operation Manual – Version 0.90

Download from Www.Somanuals.com. All Manuals Search And Download.
“Performing an update requires the controls and meters for the audio processor to be stopped. On-air audio
will not be interrupted during the update. However, a reboot is required to activate the new software, and
this will interrupt the audio. At the end of the process, you will have the option to change the current boot
bank (to activate the new software) and reboot or to keep running the current software and reboot later. Do
you want to continue the update process?”
After reading the warning message click the “Continue” button and the “Update File” dialog should
appear.
6. Click the “Browse” button, locate the software update file downloaded and saved to your computer in Step
1 and click the “Update” button.
The file will now be uploaded to the OmniaONE and this may take up to 5 minutes. Monitoring of the
progress of the upload depends on the browser being used but once the file is successfully uploaded to the
OmniaONE the following screen should appear:
7. Click the Status Page link.
Click your browser’s “Refresh Page” button until the message “Update Successful” appears. (see below)
Once the “Update Successful” message appears, click your browser’s back button. (Behavior here depends
on the browser being used – some browsers may require clicking the back button twice and then logging
back in – the goal here is to return to the Configuration page)

8. If your back button worked, select the link: “Select New Software (Configuration Page)” If not, log back
into the Omnia (default password is “omnia” (all lower case) and from the Main Menu or the navigation
menu at the top of the screen, select “Configuration”.
9. A reboot is required to activate the new software, and this will interrupt the audio. You can now opt to
change the current bank, (to activate the new software) Apply and reboot or keep running the current
software and reboot later.
To activate the new version now:
From the “Select Software Bank:” section, select the Bank that contains the new software version and
click the “Apply” button. A new page should appear with the following options:
Software bank “x” selected. (Where “x” is the number of the software bank you just selected: 0 or 1)
Return to Configuration.
Reboot Processor.
To activate the selected bank now, click the Reboot Processor option. The processor will reboot and the
new software will be activated.
Once activated its version should show now as the “Running Software:” version.
To continue running the previous version, click Return to Configuration instead. When you are ready to
activate it return to the Configuration page and repeat Step 9.
10. You may now close your browser. The software update is complete.
