ARCHITECTURAL AND ENGINEERING SPECIFICATIONS
The mixer amplifier shall have six universal inputs, each with a balanced microphone with XLR female
socket, and dual RCA line/auxiliary sockets. Auxiliary inputs 1 - 5 shall have a sensitivity of 40 while input
6 shall have a sensitivity of 200mV to accommodate a CD or other high level input.
The master section shall include one master volume control, two EQ controls, one with 12dB of boost
and cut at 100Hz and the other with 9dB of boost and cut at 10kHz. A power on/off switch with blue
“on“ LED and an LED display Vu graduated from +21dB to -3dB shall form part of this section. The
amplifier chassis shall be solidly constructed, suitable for rack mounting in a standard 19” width rack
without the need for additional rack mounting accessories.
Speaker outputs will be transformer isolated and comprise, 100 volts, 70 volt, & 8 ohms. The amplifier
must be capable of delivering 120 watts RMS at 100 volts into an 80 ohm inductive load from mains or
24V DC, with less than 0.5% distortion at 1kHz and with system hum and noise of less than -72dB.
The amplifier shall be an Australian Monitor Installation Series model SA120.
