ARCHITECTURAL AND ENGINEERING SPECIFICATIONS
The 250 watt power amplifier shall be designed to run 100 volt line audio systems. The unit shall also
features a four ohm output. The amplifier may be desk or rack mounted.
The unit shall feature high temperature protection with front panel indication. An in built auto temper-
ature sensing fan shall cool the unit when required and automatically turn off again once the amplifier
is running at the correct temperature. The amplifier must be capable of delivering 250 watts into a forty
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 AMIS250P.
