The mixer/amplifier shall control and mix up to six input signals and
deliver an audio output of 240W into 8 Ohm, 25V, 70V, and 100V.
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 fan assist 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 -50/-10dBv sensitivity. The MIC / TEL input impedance
shall be 10k Ohms or 600 Ohms with optional input transformer. The
MIC/TEL input shall include an auto mute (VOX Mute) sensitivity
control. The MUTE SENSE control will allow threshold adjustment of
mute activation. The mixer/amplifier shall include 4 switch selectable
MIC/Line inputs. The MIC/Line input impedance shall each be 10k
ohms. The mixer/amplifier shall have defeatable global Phantom
power. The mixer/amplifier shall include a stereo summing auxiliary
input, unbalanced, -10dBv, with dual-RCA jacks. The Auxiliary input
impedance shall be 10k Ohms.
The mixer/amplifier shall include two Zone 2 outputs, a 1W at 8 Ohms
output and a transformer isolated 600 Ohm output with a maximum
level of 1.5V. The Zone 2 outputs shall be assigned to the auxiliary
input and has one rear panel rotary level control for both outputs.
The mixer/amplifier rear panel input and output interconnects shall
be via Phoenix and terminal connectors. The mixer/amplifier Mute
assignment for Inputs 2-6 is via a rear panel dipswitch. Input Mute
is accomplished via the REMOTE MUTE function, controlled by an
external switch closure or via Input 1 VOX. The Mute assignment shall
not affect the Zone 2 output.
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 mixer/
amplifier shall have a Tape-Out RCA unbalanced output. The Tape
-Out shall be Pre Tone and the Low Cut Filter The mixer/amplifier
shall have a Line A and B RCA unbalanced output. The Line outputs
are POST Master Level, tone controls, Low Cut Filter and Power Amp
In. The mixer/amplifier shall have a Pre-Out RCA unbalanced output.
The Pre Out shall be POST Tone, Low Cut Filter and Pre Master
Level. The mixer/amplifier shall have a Power Amp input for use with
an external signal processor. The Power Amp In shall be Pre Master
Level. Both the Line and Pre Outputs shall be calibrated to 0dBv and
equals 1V RMS out.
The mixer/amplifier shall incorporate a balanced Bridge input/output
allowing multiple amplifiers to be combined as one mixed bus. The
Bridge input shall be activated via an external switch closure. The
mixer amplifier shall incorporate VCA remote level control circuitry
for either Master or Auxiliary level via an optional external 10K
potentiometer.
The AA240 front panel shall include volume controls for Inputs 1-6
and one Master Level control. 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 (unswitched) shall be included for
connection of external equipment. Dimensions (W x H x D) shall be
16.54" (42.01cm) x 4.21" (10.7cm) x 14.06" (35.71cm). Net weight
shall be 27.85 lbs (12.63kg). 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 AA240.
The optional rack-mount bracket kit shall be an Atlas Sound
AARMK2-0.
The optional input one transformer shall be an Atlas Sound AAIT-600.
The optional level control security covers shall be an Atlas Sound
AAVCC-5.
The optional VCA 10k Ω level control shall be an Atlas Sound
AAVC-10K.
