Introduction
Description
The ProMatrix products are designed for sound reinforcement/distribution in
multi-room applications. The PM-3180 consists of three independent ampli-
fiers, rated at 20, 60 and 100 watts. The PM-3000 is a three channel pre-
amplifier unit designed to offer the flexibility for applications with power
requirements that exceed the limits of the PM-3180. Both units have a pro-
grammable interface that lets you selectively assign priority levels to inputs
and custom configure features. As inputs become active or inactive they
are automatically switched onto or off of the channel.
Four Aux inputs and two Mic inputs lets you connect to a wide variety of
program sources. One of the Mic inputs can be set to accept input from a
telephone paging interface. The PM-3180 has outputs for 4- and 8-ohm
loads as well as 25V and 70V distributed systems, and includes provisions
to connect external signal processing equipment. The PM-3000 provides
both balanced and unbalanced line level output for each channel.
Here is an application example for a typical restaurant/bar establish-
ment using the PM-3180 amplifier: The 20-watt amp channel plays to the
entrance area/waiting room, the 60-watt amp channel to the dining area,
and the 100-watt amp channel to the bar/lounge. The area served by each
amp channel hears program material according to the priority level for the
inputs assigned to the amp channel. This example is illustrated below:

1 = Highest Priority, 6 = Lowest Priority, — = Input not assigned to amp.
The lounge audio sources and microphones are prioritized as shown, with
the Mics having the highest priorities and the music source with descending
priorities. The dining area has completely different audio needs where cer-
tain audio sources (like the paging mic and juke box) are inhibited from use
in that area while the CD and radio are permitted to play. Likewise for the
waiting area where the inputs are assigned and prioritized for that area.

Quick Start
Basic Operation
This section will show you how to:
• Apply power to the unit
• Understand the Control Panel (See page 12 for full description)
• Select which channel the control panel affects
• Change volume
• Change Bass and Treble response
• Manually select an input or allow priority-based switching
• Adjust Aux Input Trim Controls
To Apply Power to the Unit
Important Note: For PM-3000, make sure any power amplifiers con-
nected to the unit are off when the unit is first plugged in.
Connect the AC supply cord to the unit and plug it into an outlet (the unit
will turn on and display the software part number for 2 seconds and then
the unit will shut down). To apply power, press the button labeled POWER
on the control panel or on the wireless infrared remote controller.
Understanding the Control Panel
The ProMatrix unit consists of 3
channels but only one control
AUXA
panel. Therefore, you must select
the channel that the panel will
effect. Once the unit is powered,
a number of indicators will light
and the alphanumeric panel will
display status information.
The illuminated AMP 1 indicator
means that it is the “current”
amp/channel — the one that the front panel controls will now effect. AUX A
is the current active input and VOL is the current active control function.
AUTO indicates that the inputs will auto switch. The pointer LED segment
(between the large arrow keys) shows the approximate volume level.
To Select an Amp or Preamplifier Channel
To make another amp/channel current (under effect by the control panel),
press the desired button (AMP 2, AMP 3); its indicator will illuminate.
Once selected, the user can adjust the VOL, BASS or TREB control for the
selected amp/channel.

Quick Start
To Control Volume
Note: Changing any of the volume, bass or treble levels will
effect all inputs associated with that amp/channel channel.
Turning up the volume for the current amp/channel will cause
other inputs assigned to that amp/channel to play louder when
they become active. Likewise for bass and treble.
Be sure VOL is the current control (this is the
normal default function). If BASS or TREB are
lit, press the VOL button. Its indicator will light
brightly and the volume level is displayed on the
LED pointer.
Press the arrow buttons on either side of the
pointer (left to decrease, right to increase).
The display shows A1 (the active amp/chan-
A1/VOL-10
nel), VOL, and a 2-digit volume level number
(00-25). The number (and pointer) changes
in response to the arrow buttons.
After 5 seconds of no adjustment, the control
panel display will again show the current
input (VOL remains the current control and can
be adjusted at any time simply by pressing an
arrow key).
To Control Bass or Treble.
Select the desired function by pressing the
BASS or TREB button – its indicator lights.
The display shows BASS (or TREB), the current
active amp/channel (A1) and a 1-digit level
A1/bass 0
number (-7 to+7). The pointer shows the
approximate level.
Press the arrow buttons on either side of the
pointer. The number on the display changes
in response to the arrow buttons.
After 5 seconds of no adjustment, the amplifier
display will again show the current input and
VOL will again become the current function.

Quick Start
To Select a Specific Input
The ProMatrix unit is normally set to monitor input activity and, based on the
default or installer-created priority table, automatically switches the proper
input for each amp/channel. You can override the priority switching feature
of any amp/channel to select a specific input to be on continuously.
1. Press the AUTO button. Its indicator
LED will flash. and the alphanumeric
display will show SEL INPUT.
2. Press the desired input selector but-
ton (MIC A/B, AUX A/B/C/D). The
selected input will appear on the dis-
play and its indicator will flash (50%
on/50% off) in sync with the AUTO
indicator.
Note: If a different amp/channel is selected, the AUTO LED will
flicker (90% on/10% off) to indicate that one or more of the
other amp/channels is under manual control.
To identify which amplifier is under manual control
Press each AMP button until the AUTO indicator and input indicator (AUX
A, B, etc.) flash together.
To Return to Auto Switching
Find the amp/channel that is under manual control.
Press the AUTO button once. The current input (based on priority) will
appear on the display. Its indicator will light steady as will the AUTO indica-
tor (unless another channel is in manual mode, in which case the indicator
will flicker). This sets only the current amp/channel into the auto-switch
mode. Any other amp/channels that have manually selected inputs will
need to be returned to auto-switch mode using the same procedure
described above.
Note: The amp/channel must be in AUTO mode before another
manual input can be selected.

Quick Start
Aux Input Trim Adjustment
By adjusting the Trim controls as follows, inputs with different signal levels
are set approximately equal within the ProMatrix unit.
Important: You must properly set the Aux Input Trim Controls.
Improperly adjusted trims can result in high distortion levels,
poor volume balance between different inputs or false triggering
of inputs.
To adjust trims, follow the procedure below:
1. Make sure the various input sources are attached and operating at their
normal output levels.
2. Select Amp 3 as the current amp/channel.
3. Press the AUTO button and manually select one of the Aux inputs (Start
with Aux A).
4. Raise the volume of Amp 3/Aux A to 25 (this can be done without a
load, if desired).
5. Rotate the Aux A Input Trim control while watching the Amp 3 output
level meter. Adjust the trim control so that the red LED is briefly flash-
ing only on loud music peaks.
6. Repeat steps 3, 4, and 5 for the other Aux inputs. Since the inputs are
common to all three amplifier channels, the trims only need be set for
one of the amp channels.
7. For PM-3000, you must also set each of the external amplifiers volume
controls for the maximum sound level desired while the PM-3000 vol-
ume is set to 25.
Important Operational Notes
• Phantom power is turned on from the factory. To turn it off, see the
Programming Section, starting on page 22.
• When a microphone becomes active (through Vox or contact closure),
the current Aux input will be muted to a preset level. No Aux input
switching is allowed when the Aux mute is active.

Wiring Information
Outputs For PM-3180 Amplifier
Each amplifier channel has its own output terminal strip on the rear panel.
Each terminal strip can handle a different type of speaker load. All amps
can handle 70V & 25V distrib-
uted or 8-Ω or 4-Ω loads. The
70V, 25V and 8-Ω outputs are
transformer-coupled. The 4-Ω
output is directly connected to
the amplifier output. The 4-Ω
output provides a wider fre-
8-Ω Load
quency response with better
bass reproduction and lower
distortion.
To connect an 8-Ω, 25V or 70
load, attach one lead to the
COM terminal and the other to
the terminal corresponding to
the output desired. Ensure
that the shorting clip connects
COM and GND and that the
shorting clip for the LINK is
installed.
25V or 70V
Load
The transformer-coupled out-
puts (70V, 25V, 8-Ω) can be
made to float by disconnecting
the shorting clip between GND
and COM. This may be desir-
able in certain situations where
a balanced output is needed.
In general, it is best to keep the
shorting clip installed between
GND and COM.
To connect a 4-Ω load, first
remove the shorting clip
between the two screw termi-
nals marked LINK. Connect
one lead of the 4-Ω load to the
4-Ω terminal and the other lead
to the GND terminal.

User Operation
The ProMatrix Control Panel
The control panel is the interface between the user and the unit functions.
Since there are three channels (amp or preamp) and only one control panel,
the ProMatrix uses selector buttons, indicators and an alphanumeric display
to provide control of the overall functions. The information below will famil-
iarize you with the operation of the control panel.
The control panel typically shows the following information:
• The currently active amp/channel — the one that is currently under con-
trol panel control — by means of an indicator lamp.
• The currently active input — shown on the alphanumeric display and
indicator lamp.
• Input selection status — either automatic or manual selection
• The currently active control — VOL, BASS or TREB — which can be
adjusted by pressing the arrow buttons.
If the arrow keys are not touched for 5 seconds, the unit defaults to the
VOL control; you have to first select BASS or TREB to use these con-
trols.
When the ProMatrix is in User Mode, the user can perform the following
functions
• Apply power
• Select a channel
• Adjust volume and tone for all inputs on the selected amp/channel
• Manually select an input
To Apply Power to the ProMatrix Unit
To apply power, press the button labeled POWER on the control panel. or
on the wireless infrared remote controller.
To Select an Amp/Channel
In order to change the volume or tone for an amplifier channel, the
amp/channel must first be selected. To select, press the desired AMP but-
ton (AMP 1, AMP 2 or AMP 3). Its indicator will illuminate brightly. The cur-
rent input for that amp will appear on the alphanumeric display panel.
Once an AMP is selected, the user can adjust the VOL, BASS or TREB
control to the selected AMP.

User Operation
To Control Volume, Bass or Treble
Note: Changing any of the volume, bass or treble levels will effect all
inputs associated with that amplifier channel. Turning up the volume
for the current amplifier will cause other inputs to play louder when
they become active. Likewise for bass and treble.
1. To control volume, bass, or treble you must first select the desired con-
trol (VOL, BASS, TREB so that its indicator LED lights. The LED point-
er will light to indicate the approximate level setting.
2. Press the arrow buttons on either side of the pointer. The display will
show (assuming Amp 1 is the selected amplifier):
For Volume: A1/VOL-XX, where XX is a 2-digit number from 00 to 25, cor-
responding to the volume level.
For Treble: A1/TREB X, where X is a digit from -7 to +7, corresponding to
the amount of cut or boost.
For Bass: A1/BASS X, where X is a digit from -7 to +7, corresponding to
the amount of cut or boost.
3
After 5 seconds of no adjustment, the alphanumeric display will return
to the previous display and show only the current input.
Note: The volume and tone controls for a particular amplifier can be
programmed so that they do not respond to the control panel (or
infrared remote) buttons. If this programming has been performed, the
word INHIBITED will appear on the alphanumeric display when the controls
are pressed.
Note: The volume of the ProMatrix is affected by three constraints: 1)
the preset level, 2) volume changes made by the user and 3) the vol-
ume limits if set. The case may occur where the user raises the vol-
ume level to the limit set for the current input. If the input then
changes, the volume level and limit for the new input may allow further
increase of the volume. If the original input once again becomes
active, it will still be held at the limit for the second input. Now, if the
user lowers the volume of this input, the levels of all the other inputs
will change to reestablish the differences set by programming. In so
doing, all other non-active inputs may change by more than the
amount

User Operation
the current input was lowered by. This is because the levels set by the user are
temporary and the ProMatrix always strives to maintain volume differences set by
the preset programming. Typically, this will only occur when the inputs or limits are
set vastly different for the inputs assigned to an amp channel. The same applies to
the tone controls where the amp tries to maintain the EQ differences.
To Select a Specific Input
The amplifier monitors active inputs and, based on the default or installer-
created priority table, automatically switches the proper input for each chan-
nel. You can override the priority switching feature to select a specific input.
1. Press the AUTO button. Its indicator LED will flash and SEL INPUT
appears on the display panel.
2. Press the desired input selector button (MIC A/B, AUX A/B/C/D). The
AUTO LED and selected input LED will flash to indicate that auto-
switching is off for this channel.
Note: You must return to auto-switching before manually selecting
another input.
Note: If one amp is manually selected but the current amp is in Auto-
switch mode, the AUTO indicator will flicker to indicate that another
channel is under manual control. When the manually selected amp is
again made current, both the AUTO and selected input LEDs will flash.
To Return to Auto Switching
Make the amplifier under manual control the current amp by pressing the
appropriate AMP button.
Press the AUTO button. The current input (based on priority) will appear on
the display and its indicator LED will light. The AUTO LED will light steady.
Important Operational Notes
When a microphone becomes active (through Vox or contact closure), the current
Aux input will be muted to a preset (Aux Mute function) level. No input switching is
allowed when the Aux mute is active.
When a higher priority input becomes active, ProMatrix changes to that input. If that
input goes silent for more that approx. 16 seconds, the unit will fade in the next
lower priority active input. (Mics in VOX mode take aprox. 4 seconds to switch back.
In contact closure mode, the switchback is immediate.) One exception is the AUX D
input which allows aprox 30 seconds of silence before switching back. This extra
delay is provided for equipment, such Juke boxes that may have a considerable
delay between music selections. If the extra delay is needed, simply give AUX D
the desired priority level for the source connected to it. If the extra delay is not
needed, leave AUX D as the lowest priority level or remove it from the priority list if it
is not needed.

Assignment
The ASSIGNMENT function lets you assign a priority levels to each amplifi-
er-input combination. This function lets you create a variety of configura-
tion schemes and obtain maximum versatility to meet application needs.
The factory default priority levels are listed below:
Input
MIC A
MIC B
AUX A
AUX B
AUX C
AUX D
Factory Priority Level
1
2
3
4
5
6
1 = highest priority
6 = lowest priority
Note: Mic A and Mic B can only be assigned priority 1 or 2; Aux inputs
can only be assigned priority 3, 4, 5, or 6. Therefore, mics will always
have higher priority than Aux inputs. AUXD takes approx. 30 sec to
switch to lower priority input (all other Aux inputs take approx. 16 sec-
onds, Mics take approx. 5 seconds).
1. Enter programming mode and press ENT when the function title ASSIGN-
MENT appears on the display.
2. When the function is entered, the A1 /
A1/AUXA 3
AUX A (Amp 1 and Aux A) amp-input
combination is always shown, along
with that combination’s current priori-
ty assignment number (3). To select
another combination, use the AMP
buttons and Input buttons. The new
combination appears on the display
with its associated priority level.
3. A priority level can only be assigned when it is not in use by
another input. To eliminate an input priority so that it is available for
use by another, select the amp-input combination that has the desired
priority number. Press NEXT or BACK until a dash (—) appears and
then press ENT. This disconnects that input from the amp so that its
priority level is available for use with the other input.
4. Now you can select the desired amp-input combination and then press
the NEXT or BACK buttons to increment through available priority levels
(for Mics, 1 & 2; for Aux inputs, 3, 4, 5 or 6).

5. Select a level and press ENT to save the selection (PROG LED will
blink when selection has been entered).
Important: You must press ENT after every change you make
in order to save the new setting. This is true for all program-
ming procedures.
6. Repeat Step 3, 4 and 5 to assign any other inputs to the amplifier chan-
nel. Note that priority level numbers become unavailable from the selec-
tion list as they are assigned to a particular input.
Note: Priority levels do not need to be assigned consecutively.
For example, an installer could assign only 2 inputs to an ampli-
fier channel and give one the highest priority (1) and the other
the lowest (6). If the priority 1 input went inactive, the amplifier
would switch to the input with the next lowest priority (6). At
least one input source must be assigned to each amp channel
for proper operation.
7. Once you have finished assigning priorities for one amplifier, you can
press a different AMP button and proceed to program inputs for this
amplifier channel.
8. To exit the function, press EXIT. The display will again show ASSIGNMENT.
9. Press the NEXT or BACK buttons to scroll through the function menu or
press EXIT to return to users mode.

Volume Limit
This function sets the maximum volume level that a user can select for an
amp/channel-input combination.
Warning: The Volume Limit function will cause the amp-
input combination in the PM-3180 to play at the maximum
limit (default value is 25, full volume). This will normally be
quite loud. Be careful that people are not next to speakers
and that the power rating of the speakers is high enough to
handle full amplifier power. Since the PM-3000 can only
control the maximum input signal to an amplifier, the VOL
limits are only valid if the external power amplifier volume
is not changed.

Testing & Troubleshooting
Testing
Assignment
Test: Remove all audio sources from Aux inputs. Connect an active audio
source to the lowest priority input for the current amp/channel. Move the
active source through the inputs in the order of priority that was previously
set.
Result: The input source should immediately change as the audio source
is moved between inputs. If the unit delays in switching between aux
inputs then the priority schedule is set differently than expected. Reorder
the priorities using ASSIGNMENT.
Input Activity
Test: Set all audio sources so that they are active. Manually select each
input (see page 9) and check that the source plays through the amp.
Result: This checks that all used inputs are active. If certain inputs do not
play during normal operation, they may not have been assigned to an amp
channel. Reassign the input using ASSIGNMENT.
Amp Links - Internal (PM-3180 Only)
Test: Disconnect external audio processing equipment connections.
Result: No output from amps until external equipment is reconnected.
Preset Parameters
Test: Turn unit off and on. Manually select each input assigned for each
amp and check VOL, BASS and TREB settings by pushing the function but-
tons.
Result: VOL, BASS and TREBLE setting shown in display for the current
amp/channel-input combination should be what was expected. If not, enter
PRESET (see page 28) and correct settings.
Aux Mute
Test: Make one of the Aux inputs active by turning on only its source.
Select an amp and manually select a mic input. Repeat this for all
Aux/Mic/Amp combinations of interest.
Result: The active Aux input will play through the amp at the volume set by
the AUX MUTE function (see page 33). The level balance between the mic
and the muted Aux input can also be checked this way.

Testing & Troubleshooting
Vol Limit
Test: Manually select an Aux or Mic input. Press and hold the right arrow
button until the display stops incrementing.
Result: The display stops incrementing at the volume limit for the particular
input and amp combination (see page 30). Turn the Promatrix power off
and then on to return volume levels to their initial preset levels.
Troubleshooting
Display shows COM ERROR or a series of 0, +, X
• Unplug the unit, wait 5 seconds then restore power.
• Display communication problem. Look for bent, broken or dirty pins on
display panel rear connector.
• Display cable broken or bent or dirty contacts in jacks.
False triggering of non-active higher priority inputs
• Aux signal is overloading the input (see above).
• Overloaded amplifier outputs. Check that the correct output tap is
used. Recheck speaker power settings and connections.
No output from an amp (PM-3180 Only)
• Assuming that power is on, volume is turned up and input is active —
check that the shorting clip across LINK on the amplifier output termi-
nal strip is in place (except 4-ohm operation).
• Check that the shorting clip is in place between COM and GND and
that the speaker load returns to one of these. If the shorting clip is
removed, make sure the speaker load returns to the correct terminal
(see page 14).
• Check that the internal audio processing links are set to IN (see page
34).
Pop when microphone is turned on
• If the microphone is not a condenser type, be sure that phantom power
is turned off for that input.
• Some pop noise can be caused by the mechanical switching of the
mic’s on/off switch.
Mic always active
• Microphone input precedence set to N.C. (see page 26).
• Hum and noise on mic line. Check mic wiring.
• Mic manually selected (see page 9).

Testing & Troubleshooting
Mic never active
• Check that the type of precedence setting is correct for the application
(See page 26).
• If mic is a condenser type, check that phantom power is applied to mic
input (see page 27)
• Check that mic is assigned to the amp in question (see page 24).
• If Mic B is the problem, check that it is not set for Tel operation (see
page 27).
Mic distorted
• Reduce volume until output is not distorted.
• Check if ALC for that mic is turned on (see page 27).
Tel input distorted
• Make sure no DC voltage is connected to the Tel input.
• Check that Mic B is set for Tel operation (see page 27).
Aux always active
• Check if Aux is manually selected.
• Check for high levels of hum and noise from source.
Aux never active
• Check if Aux is assigned to amp in question (see page 24).
• No or very low audio signal present at aux input in question.
Music cuts in late
• Trim pad set incorrectly (see page 10).
• Energy content of music very low.
No control over volume or tone
• Check that the correct amp is selected (see page 7).
• If INHIBIT appears on the display when arrow buttons are pushed, the
function has been programmed not to respond. (see page 32).
Forgot password
• Reset password (see page 35).
