Overview

80W Mini Amplifier

The MA80 is a very compact mono amplifier designed for integration into installed audio and AV systems where de-centralisation of system components is advantageous. It is intended as an “installand-forget” component, and is small enough to be fitted into a wall or ceiling void, or in any convenient location adjacent to a projector, flat screen display or loudspeakers, for example. A simple set of controls and configuration options makes it easy to integrate into any audio system. It is highly suitable for use with in-store digital signage, gallery and museum exhibits and fixed or mobile tour guide systems.

The MA80 provides 80W Mono Output at 4Ω (low impedance). 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.

ENERGY STAR ® Tested & Certified providing extensive power saving and energy consumption saving features such as Auto Power Down (APD) and rapid waking.

The MA80 is powered internally via 100-240V SMPS. There is an optional 20mm Flexible Conduit Kit available (CA947034) for fire protection.
