Introduction
Description
The PM-3180 is a three-channel amplifier designed for multi-room applica-
tions. It consists of three independent amplifiers, rated at 20, 60 and 100
watts and a programmable interface that lets you selectively assign priority
levels to inputs and custom configure amplifier features. As inputs become
active or inactive they are automatically switched onto or off of the amp
channel. The result is unprecedented versatility and maximum usability.
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. Outputs are provided for 4- and 8-ohm loads as
well as 25V and 70V distributed systems. Provisions for connecting exter-
nal signal processing equipment is also provided for each amplifier channel.
Application Example
Here is an application example for a typical restaurant/bar establish-
ment with: 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 priorities
descending as shown. The dining area has completely different audio
needs where certain audio sources (like the paging mic and juke box) are
inhibited from use in that area while the CDand radio are permitted to play.
Likewise for the waiting area where the required inputs are assigned and
prioritized for that area.

This Quick Start section is intended to assist you in getting the PM-3180 up
and running quickly so that you can become familiar with it.
Important:When locating the amplifier, be sure to leave at
least 2 inches of space on the right side of the unit to allow for
fan exhaust. Do not place any objects directly on top of the
unit. Leave at least 2 inches of space above the unit to assure
proper ventilation.
Install Control Panel
The amplifier is shipped with the control panel disassembled from the ampli-
fier chassis. You have the option of attaching the control panel to the ampli-
fier front panel or mounting it in a convenient location and connecting it to
the amplifier using the 25-foot cable included.
Warning:Use only the cable supplied. Use of any other cable
may damage the unit.
To attach the control panel to the amplifier chassis, position the panel as
shown. Line up the tabs on the con-
trol panel with the slots on the chas-
sis. Push in on the grooved areas
on each side of the plastic panel
and push the control panel onto the
chassis to engage the locking tabs.
To mount the control panel in a
remote location:
1. Install two wall anchors 4-inch-
es apart and level in the desired location. The screws should
protrude 1/2”.
2. BE SURE THAT POWER IS OFF WHEN YOU INSTALL OR REMOVE
THE CONTROL PANEL. Plug one end of the 25-foot remote cable into
the jack on the bottom right corner of the control panel. Plug the other
end into the jack labeled REMOTE on the rear panel of the amplifier.

Quick Start
Basic Operation
This section will show you how to:
• Apply power to the amplifier
• Understand the Control Panel (See page 12 for full description)
• Select which amplifier 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 Amplifier
To apply power, press the button labeled POWERon the control panel or
on the wireless infrared remote controller.
Understanding the Control Panel
The PM-3180 consists of 3 amps but only one control panel. Therefore, you
must select the amplifier channel that the panel will affect. Once the amplifi-
er is powered, a number of indicators will light and the alphanumeric panel
will display status information.
The illuminated AMP1
indicator means that AMP
1 is the “current” amplifier
(the amp that the front
panel controls will now
effect), AUX A is the cur-
rent active input and VOL
is the current active con-
trol function. AUTOindi-
cates that the amp inputs
will auto switch. The
pointer segment shows
the approximate volume level.
To Select an Amplifier
To make another amplifier the current amplifier (under effect by the control
panel), press the desired button (AMP 2, AMP 3); its indicator will illuminate.
Once an AMP is selected, the user can adjust the VOL, BASSor TREB
control for the selected AMP. 7

5003-01.QXD 8/14/00 4:46 PM Page 11

Quick Start
To Control Volume
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
assigned to that amp to play louder when they become active.
Likewise for bass and treble.
Be sure VOL is the current control. To make
VOLthe current control, press the VOLbut-
ton. Its indicator will light brightly and the
volume level is displayed on the LEDpointer.
Press the arrow buttons on either side of the
pointer (left to decrease, right to increase).
The display shows A1(the active amp chan-
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 (VOLremains the current control and
can be adjusted at any time simply by press-
ing 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 cur-
rent active amplifier (A1) and a 1-digit level
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 ampli-
fier display will again show the current input
and VOL will again become the current func-
tion.

Quick Start
To Select a Specific Input
The amplifier is normally set to monitor input activity and, based on the
default or installer-created priority table, automatically switches the proper
input for each channel. You can override the priority switching feature of
any amp 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 SELINPUT.
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 is selected, the AUTO LEDwill flicker
(90% on/10% off) to indicate that one of the other amp channels
is under manual control.
To identify which amplifier is under manual control
Press each amplifier button until the AUTO indicator and input indicator
(AUX A, B, etc.) flash together.
To Return to Auto Switching
Find the amplifier that is under manual control. The AUTOindicator and
input indicator will flash together.
Press the AUTO button. The current input (based on priority) will appear on
the display. Its indicator will light steady as will the AUTOindicator. This
sets only the current amplifier into the auto-switch mode. Any other ampli-
fiers that have manually selected inputs will need to be returned to auto-
switch mode using the same procedure described above.
Note:The amplifier must be in AUTO mode before another
manual input can be selected.

5003-01.QXD 8/14/00 4:46 PM Page 13

Quick Start
Aux Input Trim Adjustment
By adjusting the Trim controls as follows, inputs with different signal levels
are set approximately equal within the amplifier.
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 and false trigger-
ing 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.
3.Press the AUTO button and manually select one of the Aux inputs (Start
with AuxA).
4. Raise the volume of Amp 3/Aux A to 25 (this can be done without a
load, if desired).
5. Rotate the Aux AInput Trim control while watching the Amp 3 output
level meter. Adjust the trim control so that the right most red LED is
briefly flashing onlyon 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.
Important Operational Notes
• Condenser microphones must first be configured through the Program
Mode in order to turn on the phantom power supply.
• When a microphone becomes active (through Vox or contact closure),
the current Aux input will be muted to a preset level. No input switch-
ing is allowed when the Aux mute is active.

Wiring Information
Outputs
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-Ωor 4-Ωloads. The
70V, 25V and 8-Ωoutputs are
transformer-coupled. The 4-Ω
output is directly connected to
the amplifier output. The 4-Ω
output provides a wider fre-
quency response with better
bass reproduction and lower
distortion.
To connect an 8-Ω, 25V or 70
load, attach one lead to the
COMterminal 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.
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
GNDand COM.
To connect a 4-Ωload, first
remove the shorting clip
between the two screw termi-
nals marked LINK. Connect
one lead of the 4-Ωload to the
4-Ωterminal and the other lead
to the GNDterminal.
