ARCHITECTURAL AND ENGINEERING SPECIFICATIONS
The four channel mixer amplifier shall have three universal input channels, accessible via a rear panel
barrier strip on each of the four amplifier modules. Each amplifier module shall allow remote VCA con-
trol of the master output. Phantom power selection on a per channel, per amplifier basis shall also be
included. A Vox triggered output shall also be available on an optional four tone generator card.
Each amplifier master section shall include one master VCA accessible gain control, two EQ controls,
one with 12dB of cut and boost at 100Hz and the other with 9dB of cut and boost at 10kHz. Speaker
outputs shall be transformer isolated at 100 volt, 70 volt & 8 ohms. The amplifiers must be capable of
delivering 60 watts RMS into a 160 ohm inductive load, with less than 0.5% distortion measured at
1 kHz and with system hum and noise of -74dB or better.
The amplifier shall be an Australian Monitor Installation Series model ACM604.
