Description
The DCM120 is a high performance 120 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 DCM120 features a transformer balanced line level XLR input with a parallel output to
feed additional amplifiers. The DCM120 provides 100 volt, 70 volt and 4 & 8 ohm speaker out-
puts 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 DCM120 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 DCM120 features 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 DCM120
features generous heatsinking and fan cooling. The fan will only switch on if the operating tem-
perature 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 DCM120 can operate from both AC and 24V DC and includes a built-in trickle charge
circuit.
