Product Description
The ACM120P is a 120 watt single channel power amplifier designed for commercial installations. It can be used for
either low impedance (4 or 8 ohm) or 70v/100v line speaker systems. The amplifier can be mounted in a standard 19”
equipment rack (rack ears supplied) or it can be used on a shelf or table. The ACM120P features a line level input (with
parallel output) and is normally used with mixers, mixer amplifiers or other power amplifiers.
ACM120P, 120 Watt Power Amplifier
Front Panel Features
Power Switch
The black rocker switch on the right hand side of the front panel is used to switch the amplifier on and off. The ‘up’
position is on. When the amplifier is connected to an appropriate AC power source and is switched on, the blue power
LED will illuminate.
On LED
The blue “On” LED above the power switch will illuminate when the amplifier is connected to mains power and is
switched on.
Signal LED
The green “Signal” LED located next to the On LED indicates that the ACM120P is receiving audio signal via its line level
input. The signal LED is a simple method to trouble-shoot installations especially in multi amplifier projects. At a glance
the signal LED will indicate that audio is reaching the amplifier.
Rack Mounting
The ACM120P is supplied with rack ears attached to allow mounting within a standard 19” equipment rack. As is the
case with almost all audio products, adequate ventilation and air flow is required. When installing multiple ACM120P
power amplifiers within the one rack, it is recommended that at least one rack unit of ventilation space is left between
every two amplifiers.
For table or shelf mounting, the rack ears can be removed using a screwdriver. Once the rack ears are removed, please
reinstall the screws.
