The best part of having a ProMatrix to manage
your facility’s audio is that you don’t have to operate it at all.
2 7
Bogen’s ProMatrix Model PM3180 is a three-channel
amplifier designed specifically to address the needs of
complicated sound installations. This product solves
multi-input, multi-zone application problems by providing
immense flexibility for audio control and distribution in
a single package.
The heart of the ProMatrix is an analog signal processor
and microprocessor which control audio level, equaliza-
tion, compression, input routing, and power amplification.
Through easy-to-understand setup menus, the ProMatrix
can be instructed to handle audio signals in ways that
would normally require banks of equipment and compli-
cated wiring schemes. It even includes a detachable
front panel for the ultimate installation flexibility.
Even though the ProMatrix solves complicated audio
installation problems, it is not complicated to use. It was
created with the understanding that non-technical
people will be the ones using the system long after the
installation is complete. Operation is simple and intuitive
because of its large, cleanly laid out control panel.
However, the best part of having a ProMatrix PM3180
amplifier to manage a facility’s audio is that you don’t
have to operate it at all.
The ProMatrix can be set to automatically switch input
sources and apply preset levels for volume, bass, and
treble as each prioritized input becomes active.
The ProMatrix uses a common set of inputs, but each
channel has independent control over input priorities,
volume, and EQ levels. For example, this ensures that
when someone in a facility’s bar area puts a dollar
in a jukebox, the music comes on loud and heavy
while the background music in the dining room stays
calm and quiet.
For the installer, the PM3180 is about as easy to install
as a home stereo. Simply plug in the audio input sources,
wire the speaker load to the amplifiers and the system is
up and running. The unit comes from the factory set so
that you’ll hear audio as soon as you press the power
button. Then simply enter the password-protected
programming mode and customize the system operation.
The programming mode gives you access to numerous
features that makes complicated installations a breeze.
adjust the level to the desired maximum. Different input
sources on the same amplifier can have different volume
limit settings.
In this application we will set limits only in the bar area. For
the background music and the CD player, the limits will be
set at half the maximum. For the jukebox and TV, the level
is set by ear to what the owner considers to be appropriate.
Two of the zones in this installation, the Waiting and Dining
Rooms, are not to be adjusted by the user after the
initial setup. To protect the system from tampering, the
INHIBIT feature can be used. The volume, bass, and treble
controls for each amplifier channel in the PM3180 can be
individually inhibited from operating. Either the volume or
bass and treble, or both can be inhibited from operating.
In this application we select AMP 1 and select ON for the
volume inhibit. Selecting ON means that the inhibit fea-
ture is on, indicating that the associated control buttons
don’t operate. We select the same setting for AMP 3.
The PM3180 is capable of muting an AUX input source to a
predetermined level while a page is in progress. Once the
page has finished the AUX input will fade back to its original
level. Setting the level to which the AUX input is suppressed
is accomplished by using the AUX MUTE menu function.
To set this feature you must select the amplifier and input
source combination to be adjusted. Also, for AUX mute
level setting, you must select a microphone input. The
PM3180 has the ability to mute an input source differently
depending on which microphone input is being used.
This ability is desirable in situations when one microphone
is to be used for emergency announcements and another
is for general paging. The PM3180 can be set to complete-
ly mute background music during emergency announce-
ments, but only partial muting on normal pages.
Once the amplifier/input/MIC combination has been
selected, it’s only a matter of using the volume control
buttons to adjust the AUX input mute level. The micro-
phone is live while making this adjustment so the volume
difference between the AUX input and microphone level
signals can be evaluated. The microphone volume during
this setup mode is the same as the PRESETS level and
can not be adjusted.
In this application we set the muting levels in the bar and
waiting area. The volume of the different input sources
are each set to be approximately 10 dB lower than the
microphone level.
The last step in this installation is to program the PM3180
to replace the default input display names with the name
of the input source. The LABELS menu is used to cus-
tomize the name of the 6 input sources. Names must be
no more than 10 characters (A to Z, 0 to 9, -, /, or “space”).
In this application we set the microphone input name to
PAGE, the CD player to CD CHANGER, the background music
service to BGM, the TV AUDIO and jukebox to JUKEBOX. You
scroll through a list of available characters to select one so
only a few buttons are used to edit the name.

To begin system configuration, enter the password to
begin programming mode. Once entered, you can scroll
through 10 different system configuration menus.
The first function to be configured is the microphone input.
The MICROPHONE menu allows the page activation
method to be selected (VOX triggered, N.O. or N.C. contact
closure). It also allows the Automatic Level Control and
Phantom Power for the input to be enabled or disabled. For
MIC B only, two different types of inputs (microphone or
600-ohm telephone) can also selected through this menu.
This application uses a push-to-talk condenser mic con-
nected to the MIC B input terminal strip. MIC B is config-
ured for normally opened contact closure activation, ALC
enabled, and Phantom Power enabled. MIC A is not used
so no changes are made to the factory settings.
The priorities of the different input sources are assigned
using the ASSIGNMENT menu function. For the auto-
switching ability of the ProMatrix to be of use to the sys-
tem, some order of priority must be given to the different
input sources. This will determine when one input over-
rides another. Because different zones have different
requirements, each amplifier can have different input pri-
ority assignments. The Coverage Zone Priority (on page 4)
defines the order of priority for the input sources for each
speaker zone. An amplifier and input combination can
also be assigned no priority, which effectively disconnects
that input from the specific amplifier channel.
One note on priority setting: Microphone inputs can only
be assigned the two highest priorities (1 or 2), AUX inputs
can be assigned the 4 remaining lower priorities (3 to 6).
So the PM3180 cannot be configured to allow an AUX
input to override a microphone input.
For this application the desired amp/input combinations
are given priorities that conform to the data in Coverage
Zone Priority (on page 4). All unspecified amp/input com-
binations are given no priority.
The PRESETS menu provides a means to set the turn on
levels for the volume, bass, and treble of the input sources
for each amplifier channel. It also allows different inputs
on the same amplifier channel to have different volumes.
For example, the background music in the bar area plays
at a low level until the higher priority jukebox comes on.
This source then overrides the background music and the
volume level increases significantly. When the jukebox fin-
ishes playing, background music returns, playing at its
original level. The bass and treble functions work in a sim-
ilar way and allow different equalization to be applied to
the different input sources. These settings are also made
through the PRESET function.
The adjustments are made while the PM3180 is playing
the input source through the particular amp being config-
ured. This makes it a simple matter to evaluate if the set-
ting is producing the desired results.
One thing to be aware of is how the preset levels react
when the user changes the volume, bass, or treble. When
the user makes a change, it effects all the assigned inputs
equally. Therefore increasing the level of the CD player by
3 volume steps will also make the jukebox 3 steps louder
when it becomes active. Bass and treble respond in a
similar fashion. In this way, the relative level differences
that were preset between inputs remain intact.
In this application the CD player and background music
feeds are set to play at the same low level on all amplifier
channels. However, in the bar area, the TV is to be some-
what louder than the CD and the jukebox is to be set at a
reasonable level for foreground music.
One of the requirements of this installation is to provide
the bartender limited control over the volume in the bar
area. This provision is made to ensure the volume levels
can never be made so high as to annoy the patrons.
Limiting output volume is accomplished using the VOL
LIMIT menu feature.
The amplifier and input source to be limited is selected.
The source will play at full volume when first selected
because the factory set limit is full volume. As a precau-
tion, because the input source can come on at full volume,
the level ramps up over 2 seconds to give anyone close to
a speaker time to react and protect their hearing. Now it’s
a simple matter of using the volume control buttons to

Variable AUX Muting
The ProMatrix can be set to provide partial muting of AUX
input signals during a page. The amount of muting applied to
an AUX signal can be different depending on which micro-
phone input is used to make the page. For example, MIC A –
which is used for emergency announcements – can fully mute
the AUX input level, while general paging MIC B is partially
muted. For additional flexibility, each AUX input can be set to
mute at a different level and they can be set differently for the
different amplifier channels.
Tampering Protection
Because the ProMatrix can operate without the need for user
intervention, it is sometimes desirable to inhibit the operation
of the volume and tone controls of the amplifier to
protect against tampering. Each amplifier channel can be
independently inhibited and the volume or tone controls can
be individually inhibited.
Labeling Inputs
The 10-character alphanumeric display on the control panel
can be programmed to show the “label” or name of the input
that is currently playing. The ProMatrix comes from the
factory with default labels; however, these labels can be
changed to ones that are more meaningful to the user, such
as the name of the actual input device – CD PLAYER, TV, etc.
Audio Process Links
The ProMatrix provides audio processing capabilities that can
satisfy most installations. However, audio processing links
are provided on the PM3180 for each amplifier channel so
that external signal processing devices can easily be added
into the system. The links are switched through software
commands so there are no slide switches to be tampered
with or metal clips to be lost.
AUX Trim Controls
Input trim controls are provided to accommodate a wide
range of auxiliary input signal levels (100mV to 2.5V).
Inputs/Outputs
The ProMatrix provides 2 MIC inputs, 4 AUX inputs, and 3
amplifier outputs. Power ratings are 100W, 60W and 20W.
Output impedances match 4-ohm, 8-ohm, 25V, and 70V
speaker systems. The 4-ohm output is a direct output from
the amp, all others are transformer-isolated.
Detachable Control Panel
In many applications it is desirable to mount audio equipment
in an out of the way place. However, this makes the operation
of equipment difficult or inconvenient. The ProMatrix solves this
problem by allowing its control panel to be removed and mounted
in a more convenient location. The unit comes with wall mount-
ing hardware and a 25 ft. data cord. An optional wall mount kit
is available which allows in-wall wiring at a greater distances.
Automatic Operation
Even though the ProMatrix was designed to be easy to operate,
its greatest benefit may be that it does not have to be operated
at all. The ProMatrix is capable of completely autonomous
audio system operation.
The ProMatrix can be set to switch inputs based on user
assigned priorities. Volume, bass, and treble adjustments
can be associated with each input. So when an input is
switched in, the operating level will change with it. Users still
have the ability to manually select an input which will defeat
automatic operation.
Reinstating automatic operation is as simple as a single but-
ton push. All three amplifier channels work independently of
each other so defeating automatic operation on one amp has
no effect on the others.
Auto Switching
During the initial set up of the ProMatrix, different inputs can
be assigned unique priorities. The ProMatrix continuously
monitors the audio activity on all inputs. When it detects
activity on an input with a higher priority than the current one,
it immediately switches to it. When activity in a higher priority
input stops for greater than 12 seconds, the next lowest
priority active input will fade back in. The 12-second delay
prevents the ProMatrix from switching during short pauses
between songs. The microphone inputs switch back after
3 seconds of silence or immediately when using a contact
closure to activate paging.
I/R Remote Control
The ProMatrix infrated remote control provides a convenient
wireless means of control. All functions of the front control
panel are accessible by the remote control. The receiving
sensor is located on the front of the main unit.
Simple Hookup
The ProMatrix is no more difficult to hook up than a typical
home stereo. Simply plug in input sources and then connect
the speakers. The ProMatrix eliminates the complicated
wiring between the various pieces of equipment normally
required in sophisticated audio installs.
Simple Operation
System operation is simple and intuitive. The ProMatrix was
designed from the start with the understanding that non-tech-
nical people may need to operate it. For this reason it was
given a large, easy-to-understand front panel and made to
operate like a home stereo.
Simple Setup
All configuration and set up adjustments are made through
easy to use function menus. Access to the menus are protected
by a password to protect against tampering.
Assignable Input Priorities
Because the needs of different speaker zones can differ
greatly, the ProMatrix provides a very flexible way of assigning
priorities to the input sources. The 6 inputs of the ProMatrix
are shared by all three channels but each channel can have
a completely different order of input priorities. The only
restriction on the order of priorities is that the microphone
inputs must always be higher than AUX inputs.
Presets
A group of default parameters for each amplifier in the
ProMatrix control the initial levels of volume, bass, and treble.
This feature allows different equalization to be applied to
each input source and different volume levels to be set for
different inputs on the same amplifier. In this way certain
inputs can be set to play at louder levels while others play
softly. Also the difference in volume levels is maintained as
the user raises and lowers the system volume.
Flexible Microphone Inputs
Both of the MIC inputs on the ProMatrix are low-impedance
balanced inputs. Phantom power and automatic level control
can be independently enabled for each input. The ProMatrix
accommodates 3 different methods of activating a page:
voice-activated (VOX), normally open, or normally-closed
contact closure. One MIC input can be selected to operate as
a 600-ohm transformer-balanced telephone paging input.
Volume Limiting
Many times it is desirable to allow the user the ability to
adjust volume levels. However this also allows the user the
freedom to push the level much louder than what may be
acceptable to other listeners. The ProMatrix allows a limit to
be placed on the volume level to which an amplifier channel
can be raised. Limits can be set differently for each amplifier
channel. For added flexibility, the inputs assigned to each
amplifier channel can be set to a different limit.
ProMatrix Features & Controls
Coverage Zone Priority
The following application example shows the ProMatrix in
a typical medium-size restaurant. The ProMatrix controls
a variety of input sources preprogrammed for the specific
listening environment.
The chart below shows the speaker zones and input
sources for this application. The Waiting and Dining Rooms
use the same input sources, however the Bar will also use
the TV audio and/or the jukebox. The plan is to use the CD
changer as the primary music source in the
Waiting and
Dining Rooms with the background music feed as a backup.
A push to talk microphone will be used to page into the
Bar and Waiting Area and will include variable music
muting. The TV and jukebox are used only in the Bar.
The jukebox is turned off whenever a special event is
on the TV.
The bartender is allowed some control over the volume in
the Bar, but a limit on the volume is necessary, and the
jukebox is to be set to play somewhat louder than the BGM
sources. The Waiting and Dining Room amps, once set,
are not to be adjusted.

ority assignments. The Coverage Zone Priority (on page 4)
defines the order of priority for the input sources for each
speaker zone. An amplifier and input combination can
also be assigned no priority, which effectively disconnects
that input from the specific amplifier channel.
One note on priority setting: Microphone inputs can only
be assigned the two highest priorities (1 or 2), AUX inputs
can be assigned the 4 remaining lower priorities (3 to 6).
So the PM3180 cannot be configured to allow an AUX
input to override a microphone input.
For this application the desired amp/input combinations
are given priorities that conform to the data in Coverage
Zone Priority (on page 4). All unspecified amp/input com-
binations are given no priority.
The PRESETS menu provides a means to set the turn on
levels for the volume, bass, and treble of the input sources
for each amplifier channel. It also allows different inputs
on the same amplifier channel to have different volumes.
For example, the background music in the bar area plays
at a low level until the higher priority jukebox comes on.
This source then overrides the background music and the
volume level increases significantly. When the jukebox fin-
ishes playing, background music returns, playing at its
original level. The bass and treble functions work in a sim-
ilar way and allow different equalization to be applied to
the different input sources. These settings are also made
through the PRESET function.
The adjustments are made while the PM3180 is playing
the input source through the particular amp being config-
ured. This makes it a simple matter to evaluate if the set-
ting is producing the desired results.
One thing to be aware of is how the preset levels react
when the user changes the volume, bass, or treble. When
the user makes a change, it effects all the assigned inputs
equally. Therefore increasing the level of the CD player by
3 volume steps will also make the jukebox 3 steps louder
when it becomes active. Bass and treble respond in a
similar fashion. In this way, the relative level differences
that were preset between inputs remain intact.
In this application the CD player and background music
feeds are set to play at the same low level on all amplifier
channels. However, in the bar area, the TV is to be some-
what louder than the CD and the jukebox is to be set at a
reasonable level for foreground music.
One of the requirements of this installation is to provide
the bartender limited control over the volume in the bar
area. This provision is made to ensure the volume levels
can never be made so high as to annoy the patrons.
Limiting output volume is accomplished using the VOL
LIMIT menu feature.
The amplifier and input source to be limited is selected.
The source will play at full volume when first selected
because the factory set limit is full volume. As a precau-
tion, because the input source can come on at full volume,
the level ramps up over 2 seconds to give anyone close to
a speaker time to react and protect their hearing. Now it’s
a simple matter of using the volume control buttons to

The best part of having a ProMatrix to manage
your facility’s audio is that you don’t have to operate it at all.

Bogen’s ProMatrix Model PM3180 is a three-channel
amplifier designed specifically to address the needs of
complicated sound installations. This product solves
multi-input, multi-zone application problems by providing
immense flexibility for audio control and distribution in
a single package.
The heart of the ProMatrix is an analog signal processor
and microprocessor which control audio level, equaliza-
tion, compression, input routing, and power amplification.
Through easy-to-understand setup menus, the ProMatrix
can be instructed to handle audio signals in ways that
would normally require banks of equipment and compli-
cated wiring schemes. It even includes a detachable
front panel for the ultimate installation flexibility.
Even though the ProMatrix solves complicated audio
installation problems, it is not complicated to use. It was
created with the understanding that non-technical
people will be the ones using the system long after the
installation is complete. Operation is simple and intuitive
because of its large, cleanly laid out control panel.
However, the best part of having a ProMatrix PM3180
amplifier to manage a facility’s audio is that you don’t
have to operate it at all.
The ProMatrix can be set to automatically switch input
sources and apply preset levels for volume, bass, and
treble as each prioritized input becomes active.
The ProMatrix uses a common set of inputs, but each
channel has independent control over input priorities,
volume, and EQ levels. For example, this ensures that
when someone in a facility’s bar area puts a dollar
in a jukebox, the music comes on loud and heavy
while the background music in the dining room stays
calm and quiet.
For the installer, the PM3180 is about as easy to install
as a home stereo. Simply plug in the audio input sources,
wire the speaker load to the amplifiers and the system is
up and running. The unit comes from the factory set so
that you’ll hear audio as soon as you press the power
button. Then simply enter the password-protected
programming mode and customize the system operation.
The programming mode gives you access to numerous
features that makes complicated installations a breeze.
adjust the level to the desired maximum. Different input
sources on the same amplifier can have different volume
limit settings.
In this application we will set limits only in the bar area. For
the background music and the CD player, the limits will be
set at half the maximum. For the jukebox and TV, the level
is set by ear to what the owner considers to be appropriate.
Two of the zones in this installation, the Waiting and Dining
Rooms, are not to be adjusted by the user after the
initial setup. To protect the system from tampering, the
INHIBIT feature can be used. The volume, bass, and treble
controls for each amplifier channel in the PM3180 can be
individually inhibited from operating. Either the volume or
bass and treble, or both can be inhibited from operating.
In this application we select AMP 1 and select ON for the
volume inhibit. Selecting ON means that the inhibit fea-
ture is on, indicating that the associated control buttons
don’t operate. We select the same setting for AMP 3.
The PM3180 is capable of muting an AUX input source to a
predetermined level while a page is in progress. Once the
page has finished the AUX input will fade back to its original
level. Setting the level to which the AUX input is suppressed
is accomplished by using the AUX MUTE menu function.
To set this feature you must select the amplifier and input
source combination to be adjusted. Also, for AUX mute
level setting, you must select a microphone input. The
PM3180 has the ability to mute an input source differently
depending on which microphone input is being used.
This ability is desirable in situations when one microphone
is to be used for emergency announcements and another
is for general paging. The PM3180 can be set to complete-
ly mute background music during emergency announce-
ments, but only partial muting on normal pages.
Once the amplifier/input/MIC combination has been
selected, it’s only a matter of using the volume control
buttons to adjust the AUX input mute level. The micro-
phone is live while making this adjustment so the volume
difference between the AUX input and microphone level
signals can be evaluated. The microphone volume during
this setup mode is the same as the PRESETS level and
can not be adjusted.
In this application we set the muting levels in the bar and
waiting area. The volume of the different input sources
are each set to be approximately 10 dB lower than the
microphone level.
The last step in this installation is to program the PM3180
to replace the default input display names with the name
of the input source. The LABELS menu is used to cus-
tomize the name of the 6 input sources. Names must be
no more than 10 characters (A to Z, 0 to 9, -, /, or “space”).
In this application we set the microphone input name to
PAGE, the CD player to CD CHANGER, the background music
service to BGM, the TV AUDIO and jukebox to JUKEBOX. You
scroll through a list of available characters to select one so
only a few buttons are used to edit the name.
