Description

The MA80 is a compact Mini Amplifier providing 80W Mono Output at 4Ω (low impedance). Designed for integration into commercial audio installations and AV systems where de-centralisation of the system component is an advantage. It is intended as an “install and forget” component and is small enough to be fitted into a wall or ceiling void, or directly adjacent to a projector, flat screen or loudspeaker.

Fitted with a Microphone Input with EQ and input gain adjustment, a further two line inputs, an RL-1 remote wall plate connection, music mute connection and dip switch settings providing Line 1 priority and mic priority switching in addition to switching on/off of the RL-1 functionality.

The MA80 is powered internally via 100-240V SMPS.

There is an optional 20mm Flexible Conduit Kit available (Warepart: CA947034) for fire protection.
