AMIS120P, 120 Watt Power Amplifier

Product Description

The AMIS120P 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 25v/70v line speaker systems. The amplifier can be
mounted in a standard 19” equipment rack (rack ears supplied) or it can be mounted on a shelf or table. The
AMIS120P features a line level input (with parallel output) and is normally used with mixers, mixer
amplifiers or other power amplifiers. The AMIS120P also features 24 volt DC operation.

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. This switch will not switch DC power on or off in DC
operation. In DC operation mode, the amplifier is always on and the blue power LED will always be
illuminated.

‘On’ LED

The blue “On” LED above the power switch will illuminate when the amplifier is connected to mains
power and is switched on, or when the amplifier is connected to DC power.

Signal LED

The green “Signal” LED located next to the ‘On’ LED indicates that the AMIS120P is receiving audio
signal via its line level input. The signal LED is a simple way 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 AMIS120P 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 AMIS120P 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.

Rear Panel Features

AC Power Inlet

The 3 pin IEC power inlet is located at the bottom left of the rear panel and accepts a standard mains power
lead fitted with an IEC connector.
