1. Power Switch
This push on/push off switch applies power to the AA120M.

2. Power LED
This LED illuminates when the power switch is turned on.

3. Peak LED
The PEAK LED will illuminate when the AA120M is in a clipping condition, caused by excessively high

input levels or a GAIN control is turned up too high. An occasional fl ash is OK.

4. Signal LED
This LED will assist you in setting gain structure into the amp. With a source connected to the amp and
playing, turn up the channel gain control until this LED just starts to fl ash. Once all the sources
connected are playing, the SIGNAL LED may be on solid. This condition is normal.

5. Master Gain Control
The MASTER GAIN CONTROL will raise or lower all the input channels together. A good starting point
for setting gain structure is to set MASTER GAIN CONTROL at the 12:00 position, and then adjust
the individual channels one at a time.

6. Input 1-6 Controls
The gain for input channels 1-6 are controlled by these rotary controls. The MASTER GAIN CONTROL
must be turned up in addition to the input controls for audio to be present at the speaker terminals.

7. Bass Control
Normally set at the 12:00 position, rotating clockwise will increase (boost) bass frequencies by
10dB at 100Hz. Rotating counter-clockwise from the 12:00 position will decrease (cut) bass frequencies
by 10dB at 100Hz

8. Treble Control
Normally set at the 12:00 position, rotating clockwise will increase (boost) treble frequencies by 10dB at
10kHz. Rotating counter-clockwise from the 12:00 position will decrease (cut) treble frequencies by
10dB at 10kHz.

9. Dipswitch 1-10
Understanding the functionality of the dipswitches is key to getting the most out of the AA120M.
Whether a switch is in the "Up" or "Down" position is critical to the function of the amplifi er. Note:
Mispositioning any of these switches may cause harm to the speakers or amplifi er. We recommended
powering off the amplifi er prior to making any switch selections. Pay close attention to the assignment
chart and manual for proper settings.

Dipswitch 1- LOW CUT – When in the "ON" position, frequencies below 400Hz are attenuated
at the rate of 6dB per octave. Note: The rotary bass control is bypassed when the LOW CUT fi lter
is engaged. We suggest that when paging horns are connected to the AA120M, engage the LOW
CUT fi lter to prevent the horns from operating below their cutoff frequency. When "OFF", the
amplifi er operates full bandwidth.

Dipswitch 2- VCA – When set to the "Master" position, the VCA control port acts as a system
remote volume control, adjusting all the input channels up or down simultaneously. When set to
the "Input 5" position, the VCA remote control port affects only the level of INPUT 5.

Dipswitch 3- PHANTOM – When set to the "OFF" position, PHANTOM POWER is turned off
on INPUTS 1-4. When set to the "ON" position, PHANTOM POWER (24VDC) is available on
INPUTS 1-4.

Dipswitch 4- Relay ACT - When set to the "CC" position, the internal relay is triggered by
contact closure (see page 32). When set to the "VOX" position, the internal relay is triggered by
audio signals at INPUTS 1-4 and INPUT 6, depending upon their rear panel switch setting.

11. Input 1 Trim
This variable control adjusts the sensitivity of INPUT 1. When the dipswitch is set to "Mic" it allows fine
tuning of the input gain structure to the AA120M. There is 20dB of variable gain available. This feature
is PRE channel level control.

12. Mute Sens For Vox Mute Bus
This control adjusts how sensitive the mute send circuitry on INPUT 1, 2, 3, 4, or 6 reacts. Setting the
control fully counter-clockwise will lower the sensitivity, and a higher amplitude signal will be required
at INPUT 1, 2, 3, 4, or 6 to trigger the mute send circuits. Fully clockwise will raise the sensitivity of the
mute circuits, where a lower amplitude signal will trigger a mute send. Careful calibration of this

control may be required to fully utilize the mute circuits’ capabilities.

13. Mute Send On/Off
Set to the "On" position, and audio is present at INPUT 1, a mute command will be sent to the VOX
Mute bus, thereby muting any channels set to "MUTE RCV". When set to the "Off" position, no Mute
commands will be sent.

14. Inputs 2, 3, and 4
Balanced mic or line level signals connect to the (+) (–) and (G) terminals. Refer to the chart above
"Multi Function Dipswitch" for the proper setting for mic or line level operation. If you are connecting
an unbalanced line level input, tie (short) the (G) and (–) terminals together.

15. Input 5
INPUT 5 consists of stereo summing RCA jacks. These are suitable for connection to the output of
CD/DVD players. Note: INPUT 5 has factory installed mute features, please refer to Section 17 VOX
Mute Swith and Section 18 Remote Mute for details.

16. Input Trim Controls, Channels 2, 3, and 4
This variable control adjusts the MIC sensitivity of INPUT 2, 3, and 4 allows fine-tuning of the input
gain structure to the AA120M. There is 20dB of variable gain available. This feature is PRE channel
level control.

17. VOX Mute Switch For Channels 2, 3, 4, and 6
Each 3-position switch sets the VOX mute status individually for Inputs 2, 3, 4, and 6. Note: All VOX

Mute settings are over ridden when the internal Remote Mute jumpers are installed and the
contacts are connected together. Input 5 is shipped with an internal VOX Mute jumper installed and

will be muted when any channel is set to Mute Send and signal is present at the corresponding input.

SEND - Sends a (VOX) Mute command when audio is present at the input to other channels set to
(VOX) Mute RCV (Receive).
OFF - Bypasses the (VOX) Mute Send and RCV (Receive) functions.
RCV (VOX Receive) - Inputs will be Muted when other Input Channels are set to to the (VOX) Mute
Send position and audio is present at the corresponding input.

18. Zone 2 And Zone 3 Level Controls
These rotary controls will vary the signal level at the Zone 2 and Zone 3 output terminals. Fully
counter-clockwise (0) is off, fully clockwise (10) is the maximum output level. Both Zone 2 and 3 level
controls are PRE channel level controls for Inputs 1, 2, 3, 4, 5, and 6. Note: Zone 2 and 3 level
controls function identically to their corresponding inputs. See number 28 for more details.

19. Input 6 Module Slot
The Module Slot accepts optional industry standard input modules from Atlas and other vendors.
Contact Atlas Sound for a full list of module types.

20. Tape Out
Line level mono signals are available at this jack for connection to recording devices. The signal
available here is PRE tone control and low cut filter and comes from the internal mix bus.

21. Line Out
The LINE OUT connector is useful for providing unbalanced line level signal to another amplifier or
other external devices. Prior to using this feature one must understand where the internal signal pick
up point is so you can decide if it is correct for your application. We suggest you refer to the block
diagram of the AA120M to have a complete understanding of the signal flow.

Note the following conditions for LINE OUT
A. Pre Low Cut Filter
B. Post Tone Controls (meaning the settings for the Bass and Treble controls affect this signals output).
Note: Refer to "Low Cut Filter Switch for complete understanding of the LCF feature."
C. Post Amp In (meaning any signal that is inserted into the Pre AMP In jack will be present at the Line
Out).

22. Pre Out
The PRE OUT connector has Post tone control signals available to drive another power amp or
external audio devices. Use in conjunction with the AMP IN connector, an effects loop can be created
by connecting the PRE OUT jack to a device such as an equalizer then back out to the AMP IN
connector. See the connection diagram in the setup section of this manual.

23. Pwr In
The AMP IN connector is useful for converting the AA120M into a slave amp. When a line level signal
is connected to this input, the internal connection between the preamp and internal power amp is
broken. Audio signals applied to this connector are post tone control and pre master control.

24. Bridge In/Out
Certain installations have the need to combine one or more mixers together. These mixers may be in
different rooms of an install but have the need to share a page or music throughout the installation.
These terminals provide a way to send and receive balanced line level signals from the internal mix
bus of the AA120M. The "BRIDGE IN/OUT" feature is PRE Tone Controls and Low Cut Filter. The
Bridge In/Out feature allows you to send and receive a balanced signal. This is important for allowing
longer distances between the mixers. Note: This function should only be done with other Atlas Sound
mixers that have this feature. The Send and Receive signals are combined through the same
terminals. To activate this feature see Bridge Sel below.

25. Bridge Sel
The "Bridge Select (Sel)" terminals are the access point to activate the "Bridge In/Out" feature. To
activate the feature connect the two points together via an external contact closure. These two points
must be connected to send or receive any signal. By connecting the Bridge In/Out terminals of two
AA120M, a simple room combining system can be accomplished. If using a remote switch and closing
it, the "Bridge Select (Sel)" will combine the amps as one, opening the switch will separate the two
amps. Note: If combining 3 or 4 mixers together the output level will have to be adjusted before and
after Bridge Sel terminals are connected (shorted) together. We suggest utilizing the Remote Level
control when using this feature.

26. VCA
Remote location of the level control can be accomplished via the VCA control port. You can control
the overall level (Master) or just Input 5. This selection is made via Dipswitch position #2. Connect the
two leads from the optional remote volume control to these terminals. This remote level control is
POST Master and Input 5 Level Controls. Set the system's maximum levels using the amplifier level
controls and then use the remote VCA potentiometer as an attenuator from the maximum levels set.
See the VCA setup section for instructions on wiring up the potentiometer.

27. Remote Mute (Priority Mute)
The Remote Mute feature allows you to have priority mute over Inputs 2-6. It is useful when certain
channels need to be muted from a remote location. When shorting (connecting) the Remote Mute
terminals together, (G) and (M), the internally assigned channels will be muted and will override
the VOX Mute settings. Note: Input 1 cannot be VOX or Remote Muted at anytime. Input 5 is the only
channel shipped with a factory installed Remote Mute jumper. See the PCB diagram on page 23 for
Remote Mute jumper assignments.

28. Zone 2 And Zone 3 Mute Assign (Special Internal Feature)
Each input has a mute assignment function. Inputs 2-6 can be set to receive or send a mute
command. Each input also has individual Zone 2 and 3 level controls. There may be applications that
require different mute options with Zone 2 and 3 outputs. You may want a certain input muted but not
necessarily the corresponding Zone outputs.

Internally, there are jumpers to select each input's zone outputs to be PRE or POST input mute
assignment. The AA120M Zone 2 and 3 outputs are shipped with the following assignments:

Inputs 2, 3, and 4 are POST input mute assignment.
Inputs 5 and 6 are set to be PRE input mute assignment.

Example: Input 5 will commonly have a CD player inserted into to it for background and/or MOH.
The CD’s signal is fed to the amplifier output for background music and the same signal from the CD is
routed to a telephone systems MOH input via Zone 2 or 3 output. When Input 1 receives a page you
may want the CD to be muted for the background music but not the telephone's MOH. For this to
work, the internal Zone 2 or 3 jumpers for Input 5 need to be assigned to PRE Mute. See the PCB
diagram on page 23 for pin assignments.

29. Zone 3 Out
MUSIC ON HOLD port, also known as MOH. The Zone 3 signal is taken PRE Input gain.

30. Zone 2 Out
The 8Ω 1W Zone 2 output can drive an external 8Ω speaker, and is taken PRE Input gain.

QUICK START EXAMPLES

Example 1 - System Paging, BGM, and MOH with Emergency Page Override

When a page signal is received from INPUT 2 and the RMT MUTE terminals are shorted, the page will be
the only audio heard in the main system because BGM will be muted. If an emergency page comes into
INPUT 1, all inputs will be muted except for the emergency page. Note: Zone 3 MOH output will not be
muted or affected by either page scenario.

• Connect a paging mic to INPUT 1. This will be the priority emergency page over ride mic input.
Note: The INPUT 1 Trim and Sens will need to be adjusted after all the settings and connections
have been set.

• Connect a paging mic with a switch to INPUT 2.

• Connect the switch wires from the mic connected to INPUT 2 to the "RMT MUTE" terminals. Note:
The polarity on the switch to the terminals does not matter.

• Set Dipswitch 9 and 10 to the "MIC" position.

• Set INPUT 1 to Mute Send.

• Set INPUT 2 to Mute RCV.

• Connect a BGM player to INPUT 5. Note: The input gain of this channel may need to be changed for
proper level balance. Dipswitch 6 allows you to select between a 100mV or 300mV input sensitivity.

• Connect Zone 3 output to the MOH input on your telephone system. Adjust Input 5's Zone 3 output
level as needed.

Example 2 - Priority Attenuator Override Application with Message Repeater and BGM

This application makes use of the internal relay and 24VDC in conjunction with Atlas Sound optional "PA"
override volume controls. A typical scenario would be for a Fire Station, where the background music
is turned down by the wall volume controls in the evening. A page is received on INPUT 1 and the VOX
mute triggers the AA120M relay sending 24VDC to the attenuator engaging the internal override relay and
allowing the page to come through alerting the sleeping firemen. A message repeater is connected for
caller on hold playback. Note: Remote BGM level control can also be accomplished via the VCA control
for INPUT 5.

• Connect a mic to INPUT 1. Note: The INPUT 1 Trim and Sens will need to be adjusted after all the
settings and connections have been set.

• Set Dipswitch 10 to the "MIC" position.

• Set INPUT 1 to Mute Send.

• Connect the telephone message repeater to INPUT 2.

• Set INPUT 2 to Mute OFF. Turn down INPUT 2 volume control so no audio will be present at the
speaker terminal.

• Connect Zone 3 to the Telephone PBX MOH port. Adjust INPUT 2 Zone 3 Level as needed.

• Connect a BGM player to INPUT 5. Note: The input gain of this channel may need to be change for
proper level balance. Dipswitch 6 allows you to select between a 100mV or 300mV input sensitivity.

• Connect the external level controls to the 70V speaker output.

OWNER'S MANUAL

Example 3 - Optional Plug-In Module Application

The AA120M incorporates a module port that supports a variety of system options. For this example, a
plug-in chime module is used to announce a request for building entry. The chime sound would only go
to one speaker located over a security guard's area. In addition to the chime module, there is paging,
background music, and message on hold connected.

• Connect the customer's PBX page port to INPUT 1. Note: The INPUT 1 Trim and Sens will need
to be adjusted after all the settings and connections have been set.

• Set Dipswitch 10 to the "LINE" position.

• Set INPUT 1 to Mute Send.

• Connect the telephone message repeater to INPUT 2.

• Set INPUT 2 to Mute OFF. Turn down INPUT 2 volume control so no audio will be present at the
speaker terminal.

• Connect Zone 3 to the Telephone PBX MOH port. Adjust INPUT 2 Zone 3 Level as needed.

• Connect a BGM player to INPUT 5. Note: The input gain of this channel may need to be changed for
proper level balance. Dipswitch 6 allows you to select between a 100mV or 300mV input sensitivity.

• Install Chime Module to Input 6. Connect contact closure. Make sure front panel input level control is
turned down.

• Adjust INPUT 6 Zone 2 Level as needed.

• Connect the Chime Speaker to Zone 2 output terminals.

AA120M MIXER AMPLIFIER

OWNER'S MANUAL

Example 4 - Remote Level Control

Utilizing the optional plug-in modules and the Atlas Sound wall mounted VCA attenuators, we can produce
a conference room or hotel ballroom PA system with both remote Master and remote Background Music
(BGM) volume controls. Inputs 1-4 are wired to the microphone wall plates in the room and the BGM
comes from a CD player or Satellite radio receiver.

• Connect the mics to INPUTS 1-4. Note: The INPUT 1 Trim and Sens will need to be adjusted after
all the settings and connections have been set. Dipswitch 3 (Phantom power) has been turned on
for condenser type microphones.

• Dipswitches 7-10 have been set to "Mic".

• One wall mount volume control (Atlas Sound p/n AAVCC-10K) has been connected to the terminals
marked "VCA" and Dipswitch 2 is set for Master.

• Optional plug-in module, Atlas p/n AS-ML, has been inserted into the rear module slot, and the BGM
source has been plugged into the module’s line level inputs. Adjust the module’s trim control as
needed. The AS-ML is a mic or line input module with VCA capabilities.

• Another volume control (AAVCC-10K) has been wired into the VCA terminals on the MODULE. This
control will vary the BGM ONLY.

AA120M MIXER AMPLIFIER

Example 5 - Hotel Room Combining Using Two AA120Ms

This example utilizes the combining feature of the Atlas AA120M mixer amplifiers. The drawing on the
following page shows the equipment connections for two hotel ballrooms, separated by a moveable air
wall. They hotel needs to be able to have the audio system operate has one large unit (air wall open)
or two discreet systems (air wall closed). As indicated in the example, a BGM CD player is shared
between the two AA120Ms, via a "Y" cable, connected to input 5 of each mixer amp. The Bridge terminals
of both amplifiers are connected together, through a DPST switch that makes (combines) or breaks
(separates) the Bridge connections between the amplifiers. When the switch is closed, any audio signal
into either amp will be present at both amplifier's speaker outputs. A volume control and DPST switch
(see drawing for clarity) controls the room audio level and turns the music on or off in each room. For
emergency evacuation purposes, a signal from the hotel's fire alarm system is connected to channel 1
of both amplifiers, with both channel's mute sensitivity adjusted as needed. To mute all audio when the
emergency signal is present, all other channels are set for Mute receive.
