ARCHITECTURAL AND ENGINEERING SPECIFICATIONS
The mixer amplifier shall have six universal inputs each comprising of a balanced microphone with XLR
female sockets and an auxiliary input using dual RCA sockets. A balanced XLR output to drive addi-
tional power amplifiers shall also be provided.
The amplifier master section shall include one master gain control, three EQ controls, one with 12dB of
cut and boost at 100Hz, one with 12dB cut and boost at 600Hz and the other with 9dB of cut and boost
at 10kHz. Speaker outputs shall be transformer isolated at 100 volt, 70 volt and 4 ohms. The amplifier
must be capable of delivering 250 watts RMS into a 40 inductive ohm load, with less than 0.5% distor-
tion measured at 1kHz and with system hum and noise less than -74dB.
The amplifier shall be an Australian Monitor Installation Series model ACM250.
