500W AC/DC Power Amplifier
DCM500
Description
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.
