ACM120P

120W Power Amplifier

Description

The ACM120P is a 120 watt power amplifier with outputs for 4 and 8 ohms, 70 and 100 volt

line. It may be desk or rack mounted. The ACM120P features a flat screwdriver accessible gain

control on the rear panel. This amplifier features a status LED.

Inputs and Outputs

The ACM120P features a balanced line level XLR input with a parallel output to feed additional

power amplifiers. The unit has industry standard 3 pin XLR microphone sockets. The ACM120P

features 100 volt, 70 volt, 8 and 4 ohm isolated transformer outputs via a rear panel barrier strip.

Protection

Internal current limiting protects the amplifier from both overload and overdrive conditions.

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 ACM120P features generous heatsinking.

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.

ARCHITECTURAL AND ENGINEERING SPECIFICATIONS

The 120 watt power amplifier shall be designed to run 100 and 70 volt line audio systems. The unit shall

also feature a 4 and 8 ohm output. The amplifier may be desk or rack mounted.

The amplifier must be capable of delivering 120 watts into an 80 ohm inductive load with less than 0.5%

distortion measured at 1kHz and with system hum and noise of -80dB or better. Internal current limit-

ing shall protect the amplifier from both overload and overdrive conditions.

The amplifier shall be an Australian Monitor Installation Series model ACM120P.
