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 100V line speaker out-
puts 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.
This unit shall offer remote master VCA control, 24V DC and mains power operation, and a vox trig-
gered relay output.
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 at 10kHz. Speaker outputs shall be
transformer isolated at 100V, 70V and 8 ohms. The amplifier must be capable of delivering 60 watts
RMS into an 160 ohm inductive 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 AMIS60.
