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.

Balanced mic or line level signals connect to the (+), (—), and (G) terminals. Refer to the chart at the
top of the page for the following setting. Dipswitch number 10, labeled Input 1 must be set to the
proper position for mic or line level. If you are connecting an unbalanced line level input, tie (short)
the (G) and (—) terminals together. An optional Input Isolation Transformer is available if a ground
loop problem exists. See page 23 for installation. Contact Atlas Sound for more details on the Input
Isolation Transformer.

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.
