GENERAL DESCRIPTION

The Atlas Sound AA35 is a 3 input channel mixer amplifier designed for distributed
business paging and background music (BGM) systems, small to medium speech privacy
systems, and in applications where music on hold (MOH) plus paging is required.

With (1) microphone input and (2) stereo line inputs, the AA35 will accommodate a variety
of input sources including paging microphones, CD players, and digital music receivers. A
dip switch selectable matrix allows the creation of a Zone 2 mix from any or all of the input
sources for music or messaging on hold applications. 25V, 70.7V, and 8 Ohm outputs are
provided.

The output power of 35 Watts will match nicely with Atlas Sound FAP, SM, SD, and GD
series loudspeakers. In fact, in an 11’ ceiling application, the AA35 will provide power for
up to 117 SD72W loudspeakers tapped at .25 Watts each while providing upwards of 84dB
in the direct sound field at ear height!

ARCHITECT AND ENGINEER SPECIFICATIONS

The mixer/amplifier shall control and mix up to three input signals
and deliver an audio output of 35W into 8 Ohm, 25V, and 70V.
The amplifier output shall be transformer isolated with a frequency
response 50Hz to 20kHz (-3dB) with less than 0.5% THD at rated
output. The output regulation shall be less than 2dB, no load to full
load. It shall be capable of operation from a 110/120 VAC 50/60Hz
line. The mixer/amplifier shall be convection cooled. The amplifier
shall have thermal and short circuit protection.

The mixer/amplifier shall have a switch- selectable MIC/TEL balanced
input to accept either low impedance microphone or Tel/Line Level
signals with -60/-10dBv sensitivity. The MIC/TEL input shall include a
Phoenix (Euro Block) type connector. The MIC/TEL input impedance
shall be 600 Ohms. The MIC/TEL input shall include an auto mute
(VOX Mute) sensitivity control for Input 1. The MUTE SENSE control
will allow threshold adjustment of mute activation. The mixer/amplifier
shall include two stereo summing auxiliary inputs, unbalanced,

-10dBv, with dual-RCA jacks. The Auxiliary input impedance shall
each be 10k Ohms. The mixer/amplifier shall include two Zone
2 outputs, a 1W at 8 Ohms output and transformer isolated 600
Ohm output with a maximum level of 1.5VRMS. The mixer/amplifier
Zone 2 output shall be assignable from any of the 3 inputs via the
rear panel dipswitch. The Zone 2 output shall have one rear panel
mounted rotary level control for both outputs. The mixer/amplifier
shall incorporate rear panel terminals via Phoenix connector for the
REMOTE MUTE function, controlled by an external switch closure. A
rear panel dipswitch shall allow assignment of Input 2 and/or Input 3
to respond to the mute function activation. The Mute assignment shall
not affect the Zone 2 output.

The mixer/amplifier shall have a Pre-Out RCA unbalanced output.
The Pre Out shall be POST Tone and the Low Cut Filter. The mixer/
amplifier shall have a Power Amp input for use with an external
signal processor. The mixer/amplifier shall have a Line A and B RCA
unbalanced output. The Line outputs are POST tone controls, Low

Cut Filter and Power Amp In. Both the Line and Pre Outputs shall be
calibrated to 0dBv and equals 1 VRMS out. The mixer/amplifier shall
have a 400Hz 6dB per octave low cut filter. The filter can be defeated
via the dipswitch located on the rear panel. When engaged the Bass
Tone control is bypassed.

The AA35 front panel shall include Inputs 1, 2, and 3 volume controls.
System Signal, Peak and Power LEDs shall also be incorporated. The
mixer/amplifier front panel shall also include Bass and Treble tone
controls (100Hz and 10kHz, ±10dB). The tone controls shall not affect
the Zone 2 output. The mixer/amplifier front panel shall include an AC
Mains power switch.

A rear panel AC receptacle (un-switched) shall be included for
connection of external equipment.

Dimensions (W x H x D) shall be 8.27” x 3.66” x 10.87” (210mm x
276mm x 93mm) with feet or 3.48” (88.4mm) H without feet. Net
weight shall be 10.2lbs. (4.64kg). Front panel finish and material
shall be black ABS resin and case finish (and material) shall be black
powder coated sheet steel.

The mixer/amplifier shall be Atlas Sound Model AA35.

The optional rack-mount bracket kit shall be an Atlas Sound
AARMK2-5.

The optional input transformer shall be an Atlas Sound AAIT-600.

The optional level control security covers shall be an Atlas Sound
AAVCC-5.
