ARCHITECTURAL AND ENGINEERING SPECIFICATIONS
The power amplifier shall be of high quality, suitable for the most demanding PA installations and appli-
cations. The unit shall have a frequency response of no less than 50Hz - 15kHz (±3dB). Distortion at
1kHz shall not exceed 0.5%. The Signal to Noise ratio shall be -82dB or greater. The amplifier shall have
two transformer balanced XLR inputs, one of which can be used to feed additional power amplifiers.
The amplifier shall be capable of delivering 500 watts RMS into 100 & 70 volt or 4 ohm loads. Speaker
connection shall be via a rear panel barrier strip.
The unit shall operate from both AC mains power or from a 24V DC battery supply. The amplifier shall
include a built-in trickle charge circuit. The amplifier shall feature overload and overdrive protection and
shall also include cooling fans, which should only be active if the operating temperature exceeds a fac-
tory preset level.
The unit shall be packaged in a rugged 2 RU metal chassis suitable for desk or rack mounting.
The power amplifier shall be an Australian Monitor Installation Series model DCM500.
