Audiophile USB Driver & Software Installation

The Audiophile USB system includes a “Software Drivers CD” for

Windows and Macintosh, containing all Windows and Macintosh drivers

(including ASIO drivers), and Audiophile USB Control Panel software. To

install on your system, please follow these steps:

Windows Installation

An “Installer” program is provided for Windows operating systems. The

Audiophile USB Installer greatly simplifies the work that the Windows

New Hardware Wizard has to do, and helps to ensure a trouble-free and

simplified installation.

You may also notice that a “Windows Driver Signing” dialog box will pop

up a few times during the installation, and you will be asked to press

“Continue Anyway.” This dialog box indicates that this is a relatively new

product. While we are going through the driver certification procedure

with Microsoft, we assure you that your Audiophile USB drivers are of the

highest quality, and will cause no problems in your system.

1. Insert the Drivers CD into your CD ROM drive. Locate and open the

Audiophile USB folder. Double click on the Audiophile USB Installer

program in that folder.

2. As the Installer loads the Audiophile USB drivers, a “Windows Driver

Signing” (XP and 2000 Users only) dialog box may pop up a few times

during the installation. Click,“Continue Anyway.”

3. When asked to switch “On” your Audiophile USB, do so.This will bring

up theWindows New HardwareWizard. Click “Next” at each prompt,

and the Hardware Wizard should automatically recognize all of the

Audiophile Drivers.

NOTE: Windows 98SE users will need their Microsoft Windows 98SE

CD-ROM here.

the CD drive and respond by clicking “Yes”. The system will restart and

your Audiophile USB is ready for play.

Macintosh OS 9 Installation

NOTE: To use the Audiophile USB on Mac OS 9, you must also install

Opcode’s OMS. This should be done BEFORE running the Audiophile

USB’s Installer program. By installing OMS first, the Installer program

will then be able to place the OMS driver in the proper folder.Then,

after running the Installer, you will need to configure OMS. See the

section,“OMS Configuration,” for more information on installing and

configuring OMS.

1. Insert the Drivers CD into your CD ROM drive. Locate and open the

Audiophile USB folder.Open the folder for your current Macintosh OS,

and double click on the Installer program in that folder.

2. As the Installer loads the Audiophile USB drivers, you will be asked if

you wish to place a shortcut to the Audiophile USB Control Panel on

your desktop.This is your choice,but it’s probably a good idea to choose

this option.You can always trash the shortcut if you find it unnecessary.

3. After you run the Installer, you may switch “On” your Audiophile USB.

Your Audiophile USB is now ready for action.

OMS Configuration

To configure the Audiophile USB for MIDI on Mac OS 9.x, you will need to

have Opcode’s OMS (Open Music System) installed first. OMS is a “MIDI

Manager” program, and it is necessary to install this in order to run all OS

9 music programs that have a MIDI engine, i.e., programs that use MIDI.

You need to install OMS before you run the Audiophile USB’s driver

Installer program. OMS is provided on the Drivers CD that came with the

unit, and is located in the “OS 9” folder, or it can be downloaded from the

M-Audio Website’s “Drivers” page. Opening the OMS 2.3.8 folder and

double-clicking on the“Install OMS 2.3.8” program will install OMS in your

system. Restart your computer, and continue with the driver installation

(see previous section).

To configure your Audiophile USB MIDI in OMS, go to the Control Panel

or Chooser under the Apple Menu, and make sure AppleTalk is turned off

“Hardware Installation”.

Verifying Windows Driver Installation

Windows displays the Audiophile USB driver status in the Device Manager

page of the System Properties dialog box.The Device Manager page can be

opened by right-clicking on“My Computer,” either from the Start menu or

your desktop (depending on your operating system), and selecting

“Properties” from the list. Select“Hardware,” then“Device Manager.”With

the Device Manager displayed, click on the “+” next to “Sound, video and

game controllers” to open a list of devices, the Audiophile USB being a

device of that nature.You will also see an entry for the Audiophile USB

under “Universal serial bus controllers.” Below is an example view of the

Device Manager.

This example shows the M-Audio Audiophile USB entries in the Windows

Device Manager device list.The Audiophile USB is properly installed with

no conflicts. If you do not see your M-Audio Audiophile USB in your

Device Manager in this fashion,please jump ahead to the“Troubleshooting”

section of this manual.

Verifying Control Panel Installation, PC/Macintosh

On the PC: Once the Audiophile USB is properly installed, an “M-Audio

Audiophile USB” icon will be displayed in yourWindows Control Panel,which

can be accessed from the Start menu.By double-clicking on that icon,you will

launch theAudiophile USB Control Panel software.Once theAudiophile USB

Control Panel software has been opened,you will see the various controls for

enabling inputs and outputs and for setting other parameters.

With the control panel open, you will see in the lower left hand corner a

checkbox that states, “Place Audiophile icon in the task bar.” You may

create a shortcut on your Windows taskbar by clicking on this checkbox.

Upon closing the control panel, the M-Audio logo will appear in your

taskbar. Double-clicking this icon will then open the Audiophile USB

Control Panel. Unchecking the control panel checkbox will remove the

M-Audio logo from the taskbar upon closing the control panel. Note that

the M-Audio logo will only appear on the taskbar when the Audiophile is

attached and powered “On.”

On Macintosh: During the driver installation, a dialog box will ask you if

you wish to place a shortcut to the control panel on your desktop.Clicking

this checkbox will, upon completion of the driver software installation,

place a shortcut to the Audiophile USB Control Panel on your computer’s

desktop.The control panel program itself will install to your system’s hard

drive. In OS 9, the Audiophile USB Control Panel will be placed in the

Control Panel folder, which allows it to be accessed from the Apple

Control Panel drop-down list. In OS X, the control panel is installed into

the System Preferences folder.

If you choose not to place a shortcut icon on your desktop during the

installation process, you may create an alias by highlighting the Audiophile

USB Control Panel on the hard drive and pressing the Command Key+M.

The alias may then be dragged to the desktop.The control panel can be

launched from any of the above locations. Once the Audiophile USB

Control Panel software has been opened, you will see the various controls

for enabling inputs and outputs and for setting other parameters.

NOTE: When using a music software program that is ASIO capable,

launch the Audiophile USB Control Panel software from within that

program. If you need to change the master clock settings, for

instance (in other words, change from the Audiophile’s internal clock

to an external clock by selecting “S/PDIF In” from the control panel),

it is desirable to launch the music program first, and then the

Audiophile USB Control Panel from the program’s “launch” or

“control panel” button. Without the music program open however, it

is okay to open the Audiophile USB Control Panel from your desktop

or other location.

The Audiophile USB Control Panel

Certain audio settings are made in the USB Audiophile Control Panel, and

are important to the way the Audiophile performs.You may never need to

change them for your particular purposes,but it’s good to know how these

settings affect what you do and how they interact.

When the Audiophile USB driver and control panel software are first

installed, a “default” setting is created that will work for you in most

circumstances.The analog inputs are active, as well as the analog outputs

and the S/PDIF output. The S/PDIF Input is left unchecked. The “16-bit”

radio button is selected, but can be switched to 24-bit if you wish to

record at that bit depth from your music program. The Audiophile is

capable of recording at sample rates up to and including 48000Hz.

You should only check the S/PDIF Input port if you are recording audio

from the S/PDIF Input, or otherwise wish to synchronize to an external

sampling clock. Continue reading this section for more information on

making selections in the Audiophile USB Control Panel.

Active Channels & Sample Depth: Activation of the Analog and

S/PDIF inputs and outputs is done with a set of four check boxes.Two radio

buttons allow selection between sample bit depths of 16-bit or 24-bit.

These settings will interact with each other, either expanding or limiting

your Active Ports, Sample Depth, and/or Maximum Sample Rate settings.

Using the full USB bandwidth will allow for 4x4 audio streams at 16 bits

with a sampling rate of 48kHz or below.A higher bit depth or sampling rate

will demand a trade-off from your system, which can be achieved by

disabling your Active Ports.

On the right side of the control panel there are two columns labeled

“Active Channels” (Analog and S/PDIF inputs and outputs) and “Sample

Depth” (16-bit and 24-bit). Choosing the 24-bit setting will allow your

music program to record at any bit depth up to 24-bit, depending on the

variety of selections within that program.

With any combination of three stereo pair “Active Ports” enabled, the

Audiophile USB is capable of 48kHz or 44.1kHz (or lower) sampling rates at

either 24- or 16-bits.When you uncheck and deactivate any one of theActive

Ports, the 24-bit option will become available. If you select the 24-bit radio

button, and then activate all four Active Ports, the control panel will

automatically switch back to the 16-bit setting and gray out the 24-bit option.

NOTE: Please exit any audio applications running before switching

between bit depths.

The Audiophile USB will perform at 96kHz sampling rate with any one of

the stereo pairs enabled, and with the 24-bit Sample Depth selected.This

is most useful if your CD/DVD player is capable of playing “audiophile”

96kHz recordings.TheAudiophile USB will not operate at 96kHz when the

control panel is set to 16-bits.In the example below,Output 1&2 is enabled

and 24-bit Sample Depth is selected, with the Maximum sample rate

showing 96kHz.

Download from Www.Somanuals.com. All Manuals Search And Download.

If you activate both sets of input and output channels, you will notice that

the 24-bit setting in the Sample Depth column is grayed out and the

“Maximum sample rate” is shown as 48000 Hz.

NOTE: Whenever S/PDIF Input is selected as an Active Port, the

Audiophile is expecting a digital signal at that port and to lock to

the sample rate of that signal. When S/PDIF Input is selected and

there is no signal present at the S/PDIF Input port, or the S/PDIF

signal is not recognized or invalid, the Audiophile USB will not

operate properly. Most likely, you will hear audio from the

Audiophile, but it will be running at an odd sample rate and sound

like it is playing at the wrong speed.

DD/DTS Pass-Thru: Just below the Sample Depth column, you will see

a checkbox labeled,“DD/DTS Pass-Thru.” If you are using a Software DVD

player and wish to send encoded multi-channel audio such as Dolby Digital

or DTS to the Audiophile USB’s S/PDIF output port, then check this box.

If you are only sending stereo audio (standard PCM—not encoded

surround) to the S/PDIF output port during normal operation, then leave

this box unchecked.

If you have this box checked, you can still send stereo digital audio to the

S/PDIF port without any problems. However, you will notice that when the

DD/DTS Pass-Thru box is checked, ONLY the S/PDIF port is active in the

Active Ports column. Unchecking the DD/DTS Pass-Thru box will restore

the port selection to the previous configuration.

Latency: Driver “Latency” can be selected from a range of values shown

in a drop-down list located just below the “Maximum Sample Rate.” The

default setting when the Audiophile is first installed is “Very High.” Because

slower computer systems require larger sample buffers to avoid dropouts

in the audio stream, a higher latency value is often necessary.

How low you will able to set the Latency will depend on several factors,

such as your system’s performance and the performance of the music

program itself.To test your system for lower Latency, try the “very low”

setting first (as shown in the previous screenshot), and if your system

stutters or performance falters,try the next higher setting until the system

performance stabilizes.Once you are satisfied with any of the control panel

settings, click OK to close the Audiophile USB Control Panel.

Version Numbers: The lower left corner the Audiophile USB Control

Panel page displays the ASIO Driver Version, USB Driver Version, and the

Firmware Version numbers currently in use.This is useful when checking

for driver updates on the M-Audio website, or in the event that you need

to call tech support and give them your system information.

Windows Sound System and the Audiophile USB

Windows may be set up to use the Audiophile as its default audio device,

allowing system sounds to be played through the Audiophile. This also

enables you to use the Audiophile with the sound applets included with

Windows.To set this up, go to Control Panel | Sounds and Audio Devices

(or, “Multimedia” in Windows 98). In the Audio Properties page, set the

Playback and Recording devices to the Audiophile USB input and output

devices of your choice.

Windows may also use the Audiophile USB as its default MIDI device.This

allows the Audiophile USB to be used with the MIDI applications included

with Windows. To set this up, go to Control Panel | Sounds and Audio

Devices | Audio. (Or, go to Control Panel | Multimedia | MIDI in Windows

98.) Set the Audiophile MIDI driver as the defaultWindows MIDI driver by

clicking on the “Out USB Audiophile” entry in the drop-down list, then

selecting “OK” or “Apply”.

Macintosh Sound Manager and the Audiophile USB

The Macintosh Sound Manager will allow you to select theAudiophile USB

as the system’s audio input and output device. Open the Apple menu and

select “Sound” from the Control Panels list. Then choose Audiophile as

both input and output driver. However, you may also leave the Sound

control panel set to “Built-in” if you wish to use the Audiophile only with

your music program and use the internal audio for system sounds.

Audiophile USB Inputs & Outputs

TheAudiophile USB Digital Recording Interface’s analog inputs and outputs

are compatible with a variety of audio products.The Audiophile USB has

both female RCA and female 1/4” TS (tip-sleeve) input jacks, and female

RCA output jacks. These jacks allow connection to unbalanced (typically

consumer or semi-pro) line level equipment.

Only one pair of analog inputs can be used at any given time.When a 1/4”

TS plug is connected to the 1/4” line inputs, the corresponding RCA input

jack is defeated. If you have RCA cables connected to the Audiophile and

then connect 1/4” plugs to the 1/4” jacks, the Audiophile will then get its

signal from the 1/4” line inputs.

NOTE: In order to preserve its high dynamic range and minimize

distortion, the Audiophile USB does not have microphone

preamplifiers built into it. Therefore, directly connecting a

microphone is not recommended.Instead,pass the microphone signal

through a microphone pre-amp (such as the M-Audio TAMPA™,

DMP3™, or Audio Buddy™), and then connect the pre-amp output

to the input of the Audiophile USB. Some additional cable and/or

cable adaptors may also be needed to ensure proper connectivity.

The Audiophile USB also has digital inputs and outputs in S/PDIF format.

These are available on RCA connectors,as stereo pairs.These jacks receive

or transmit a digital audio stream that is independent of the analog audio

streams. However, because of the bandwidth limits of USB there can be a

tradeoff between the number of inputs and outputs that are active and the

sampling rate and bit depth of the audio being processed.Also, you should

ONLY activate the S/PDIF Input if you are connecting an active digital audio

device to this input.This is detailed in the previous section,“TheAudiophile

USB Control Panel.”

Also detailed in the previous section is the use of the S/PDIF Output for

sending encoded surround sound signals. Checking the “DD/DTS

Pass-Thru” box in the Audiophile USB Control Panel will allow you send

Dolby Digital,Dolby Surround,DTS,or any encoded surround sound signal

to the S/PDIF Output of the Audiophile USB.You can connect this output

to a home theater system, or any device that will decode this signal. Using

most DVD players, select the “S/PDIF” option in the DVD players audio

setup page, and your computer becomes a high-end home theater player

in conjunction with the Audiophile USB.

Audiophile USB with Your Music Software

Once the Audiophile USB hardware and software drivers are properly

installed, the Audiophile is ready for use with your music application

software. Some software applications may require you to highlight or

enable the Audiophile USB drivers within the program in order to use the

Audiophile, while others may have a utility that analyzes or profiles the

audio devices in your system and enables the drivers.Your software should

have an audio device driver setup page. If you have problems locating it,

consult your software’s documentation.

The Audiophile drivers include MME and WDM drivers for Windows,ASIO

drivers for both Windows and Mac, and Sound Manager drivers for Mac.

WDM drivers are a more modern driver architecture forWindows operating

systems Me, 2000, and XP, but only certain programs like Cakewalk’s “Sonar”

will take advantage of them. Other Windows programs will automatically

access and use the MME drivers.WDM drivers, similar to ASIO, will give you

low latency monitoring through the application (check your application’s

documentation for information regarding input monitoring).

If yourWindows or Macintosh program is ASIO compliant, like Steinberg’s

“Cubase” or Emagic’s“Logic,” then the program’s audio device driver setup

page will allow you to select the USBAudiophileASIO driver.This selection

is advised, and described more fully later in this section.

Windows MME and WDM Audio Input Devices: Within the setup

page of your software application(s), the names of the Audiophile USB

audio input devices will be:

“M-Audio USB Audiophile Line”, and

“M-Audio USB Audiophile SPDIF”.

The “M-Audio USB Audiophile Line” device allows recording a stereo

stream directly from the analog Left and Right Input pair, while the

“M-Audio USB Audiophile S/PDIF” device allows you to record a stereo

stream directly from the S/PDIF Input.

Note that the input devices are stereo.Your application software may

break these down further to “left” and “right” mono devices.Therefore

you may see them as “Left M-Audio USB Audiophile Line” and “Right

M-Audio USB Audiophile Line,”or“Left M-Audio USB Audiophile S/PDIF”

and “Right M-Audio USB Audiophile S/PDIF” from within your recording

software. If your application allows for recording stereo tracks, you will

also be able to select “Stereo M-Audio USB Audiophile Line” and

“Stereo M-Audio USB Audiophile S/PDIF.”

Windows MME and WDM Audio Output Devices: Within your

software application(s), the names of the Audiophile USB audio output

devices are:

“M-Audio USB Audiophile Line”, and

“M-Audio USB Audiophile SPDIF “

Most application software will handle the outputs as stereo pairs but allow

you to pan audio left or right within the pair.Therefore, to send a mono

output to the Audiophile’s Left Output (for example), choose “M-Audio

USB Audiophile Line” and pan that track hard left.To send a mono output

to the Audiophile’s Right Output, choose “M-Audio USB Audiophile Line”

and pan that track hard right.

ASIO Input and Output Devices: If your music program is ASIO

compliant, you may use the “USB Audiophile ASIO” driver with your

Audiophile USB.Open your music program and go to the audio setup page.

The “USB Audiophile ASIO” driver will show up in the program’s ASIO

Driver list, allowing you to select it at this time if it is not already selected

by default.

If you are using an ASIO compliant music program, we suggest that you

enable and use theAudiophile’sASIO drivers.ASIO gives you the advantage

of being able to monitor your source through the program, similar to

monitoring the record inputs of a tape machine. ASIO input devices will

appear as:

“M-Audio USB Audiophile Line Left”,

“M-Audio USB Audiophile Line Right”,

“M-Audio USB Audiophile SPDIF Left”, and

“M-Audio USB Audiophile SPDIF Right”.

ASIO Output devices will appear as these stereo pairs, which you will be

able to pan left and right from within your music program:

“M-Audio USB Audiophile Line”, and

“M-Audio USB Audiophile SPDIF”.

Once the Audiophile USB ASIO driver is selected in your music program’s

audio setup page, you will find a button that allows you to launch the ASIO

device’s control panel. Clicking this button will now launch the Audiophile

USB Control Panel, allowing you to view theAudiophile USB audio settings.

Audiophile USB MIDI Setup

The Audiophile’s MIDI input and output ports may be connected to

external MIDI devices.The following diagram shows connection to a MIDI

keyboard instrument,which is also being used as a sound module.The MIDI

output of theAudiophile USB may be used with just a sound module, while

the MIDI input may alternately be used to receive MIDI time code for

synchronization purposes.

1. Connect the MIDI out port of your controller keyboard to the

Audiophile’s MIDI In port using a standard MIDI cable.

2. Connect theAudiophile’s MIDI Out port to the MIDI in of your keyboard

instrument (or a sound module), also using a standard MIDI cable.

3. Connect the audio outputs of the keyboard to either a mixer, sound

system, or the audio inputs of the Audiophile USB.

The Audiophile USB MIDI drivers, once enabled in your software’s MIDI

Setup, will appear as a MIDI source and a MIDI port within that program’s

track configuration windows. The MIDI input driver is named “In

Audiophile USB”, and the MIDI output driver is named “Out Audiophile

USB”. Some software applications allow you to redefine/rename these

devices per supplied or manually entered instrument definitions.

Troubleshooting

Problem: No sound output.

Possible Cause 1:TheAudiophile USB hardware or software device drivers are not

properly installed.See the installation sections of this manual for further information.

Possible Cause 2:There is a resource conflict between your computer’s USB

controller and another device in your computer (PC only). Check the Device

Manager for your USB controller’s IRQ against those of the other installed devices.

If necessary, change the settings for the one or more of the devices (refer to your

computer or motherboard manual).

Possible Cause 3:Your application software has not been properly configured to

use theAudiophile USB as its audio output device.

Possible Cause 4: Improper connections of the audio accessories.Verify that the

Audiophile USB analog audio outputs are properly connected to a digital mix deck

or external mixer/amplifier, or the S/PDIF Out is connected to an external digital

audio device capable of receiving S/PDIF.

• Problem: I’m trying to record digital audio through the S/PDIF input but I don’t

hear any output.

• Possible Cause:The settings in theAudiophile Control Panel may be incorrect.

Double check that you have S/PDIF Input enabled and that your settings don’t

exceed the bandwidth limitations of USB. Remember that the more inputs and

outputs you have enabled, the lower the allowable sampling rate and bit depth.

Problem:The DeviceVolume control inWindows’ Sounds and Audio Devices (or

other software such as MUSICMATCH Jukebox) is grayed out and does not function.

Possible Cause: Audiophile USB does not make its volume control parameter

available to the host computer’s operating system. Use the Head Phone Level and

Output Level knobs on the front panel of yourAudiophile to adjust volume.

• Problem: No visual activity onAudio Input volume (VU) meters of user software.

• Possible Cause 1:TheAudiophile USB input devices are not properly selected

in the user’s application software.

• Possible Cause 2: Improper connections to audio accessories.

Download from Www.Somanuals.com. All Manuals Search And Download.

Problem: Repetitious Sound.

Possible Cause: An IRQ resource conflict with the USB controller and

another device (PC only). Often this will result in a small segment of sound

(0.5 to 1 second) repeating itself over and over, sometimes completely

locking up the computer. See the general troubleshooting suggestions at

the beginning of this section.

• Problem: I’m getting some pops and clicks in my audio recording.

• Possible Cause 1: Input levels are too “hot,” causing clipping or input

distortion. Make sure you have the proper signal levels coming from your

source audio device, and lower the output if necessary.The incoming levels

may be easily viewed from the Audiophile USB Control Panel peak meters.

• Possible Cause 2: Your application software may not have the proper

audio buffer sizes set. Each software application handles this differently, but

typically there is somewhere in the software’s setup to set the size of the

playback and recording buffers used by the application. Some applications

also require you to run a calibration (sometimes called“profiling”) the first

time you use the software with a new audio interface. For instance, if the

clicks are present when using Cakewalk SONAR,then try to run SONAR's

Wave Profiler.

• Possible Cause 3: Some accelerated graphics cards use excessive

amounts of system bandwidth, preventing the recording buffer of an audio

interface from keeping up with demand. This can cause clicks in the

recording. Reducing or turning off the graphics card’s graphics acceleration

feature often resolves this problem. In Windows, the level of graphics

acceleration is accessed from Start | Settings | Control Panel | System |

Performance | Graphics.

Problem: My software application keeps telling me “sample rate not

supported” or some similar message.

Possible Cause:This would most likely occur if you were trying to select

96000Hz as a sample rate, and the Maximum Sample Rate available from

the Audiophile USB Control Panel is 48000. Open the control panel, and

uncheck the Active Port boxes until you have only one port selected for

either input or output.

Problem: I am playing AC-3 or surround sound data from a software

application on my computer, sending the data from Audiophile USB S/PDIF

Out to my home theater’s AC-3 decoder. However, the decoder does not

recognize the signal and therefore refuses to put out any audio.

Possible Cause:There is a bit within the S/PDIF digital audio stream that

defines the S/PDIF content as audio or non-audio. Most AC-3 surround

sound decoders expect this setting to be non-audio and will otherwise

reject the information. Go to the S/PDIF page of the Audiophile USB

Control Panel, select Consumer and Advanced Settings, and then select

“DD/DTS Pass-Thru.”

• Problem: I have Windows 98SE and I want to install the Audiophile USB,

why do I need the original operating system CD-ROM to install your drivers?

• Answer: Windows 98SE does not have the system files to support USB

Audio installed as part of the core installation. Instead these files must be

added.The necessary files are located on theWindows 98SE CD. If you do

not have your original Windows 98SE CD, contact Microsoft Technical

about how to acquire the files for USB Audio support in Windows 98SE.
