ARCHITECTURAL AND ENGINEERING SPECIFICATIONS
The mixer amplifier shall have four universal input channels, each comprising of a balanced microphone input
with XLR female sockets and an auxiliary input using dual RCA sockets. The 70 volt line speaker outputs should
be able to be switched via a six position selector with ”all call“. A balanced XLR output to drive additional
power amplifiers shall also be provided.
The amplifier master section shall include one master gain control, two EQ controls, one with 12dB of cut and
boost at 100Hz and the other with 9dB of cut and boost and 10kHz speaker outputs shall be transformer iso-
lated at 70 volt, 4 & 8 ohms. The amplifier must be capable of delivering 120 watts RMS into an 40 inductive
ohm load, with less than 0.5% distortion measured at 1kHz and with system hum and noise less than -74dB.
The amplifier shall be an Australian Monitor Installation Series model AMIS120.
