Architect and Engineer Specifications
The mixer/amplifier shall control and mix up to four input signals and
deliver an audio output of 50 Watts into 4Ω, 25V, and 70.7V. The
amplifier output shall be transformer isolated with a frequency response
50Hz – 15kHz (-3dB) with less than 0.5% THD at rated output. It shall
be capable of operation at 120VAC 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 600Ω. 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 10kΩ. The
mixer/amplifier shall also include a summed stereo 3.5mm input. The
level for this device shall be controlled at the device and the level shall
only be affected by the Master Level control. The mixer/amplifier shall
include one Zone 2 output, a transformer isolated 600Ω output with a
maximum level of 1.0VRMS. The mixer/amplifier Zone 2 output shall
be assignable from Input 2 or Input 3 via the rear panel dipswitch. The
Zone 2 output shall have one rear panel mounted rotary level control.
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,
Input 3, and/or Input 4 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
mixer/amplifier shall have a Power Amp input for use with an external
signal processor. The mixer/amplifier shall include the Push Here
Diagnostic system test circuitry. This test will allow for automatic testing
of the connected speaker lines for wiring and impedance errors. The
mixer/amplifier shall include Phoenix connectors for both Remote Level
Control and Remote Input Selection which can be activated using the
rear panel DIP switches. The Remote Input Selection circuitry shall work
with Atlas Sound wall plate WPD-RISRL and allow Inputs 2, 3, and 4 to
be remotely connected, selected, and adjusted from the wall plate. The
AA50PHD front panel shall include Inputs 1, 2, and 3 level controls as
well as a Master Level control adjustment. System Signal, Peak, Limit,
and Power LEDs shall also be incorporated. The mixer/amplifier rear
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.
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. Front
panel finish and material shall be black ABS resin and case finish (and
material) shall be black painted sheet steel.
