The DCM500 is a high performance 500 watt power amplifier designed to meet the needs of the most demanding sound reinforcement installations and applications. The amplifier is designed to operate from both AC mains power as well as 24 volts DC.

Inputs and Outputs

The DCM500 features a transformer balanced line level XLR input with a parallel output to feed additional power amplifiers. The DCM500 provides 100 volt, 70 volt and 4 ohm speakers outputs via a rear panel barrier strip.

Controls and Metering

The front panel consists of a mains power switch and a recessed, screwdriver adjustable input attenuation control. The front panel of the DCM500 includes a back-lit LED display indicating power, high temperature, LED VU meter and mains fail indication. The mains fail indicator will only operate in the event of a mains power failure and when the amplifier is connected to a 24V DC power supply.

Protection

The DCM500 features a slow start function as well as overload and overdrive protection. Should the amplifier be overdriven, a current limiter will protect the unit, and in a worst case scenario the amplifier will shut down until the problem is resolved. Once the problem is fixed (shorted speaker line, or overdriven input), the amplifier will automatically reset and continue operation. The amplifier also features a built-in compressor/limiter designed to smooth out any peaks in input signal. The DCM500 features generous heatsinking and fan cooling. The fan will only switch on if the operating temperature exceeds a factory preset level. Australian Monitor Installation Series amplifiers feature a protection network that provides greater stability and performance. Our amplifiers are recognised worldwide for their reliability and this is due to the extensive levels of current limiting which protect the amplifiers from both overload and overdrive conditions.

Other Features

The DCM500 can operate from both AC and 24V DC and includes a built-in trickle charge circuit.
