Overview

80W Mini Amplifier with Ethernet Interface and DSP

The MA80E 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 MA80E provides 80W Mono Output at 4Ω (low impedance) and features an Ethernet Web Browser and RS232 control interface. It is fitted with a Microphone input with EQ and input gain adjustment, two line inputs and Facility Port input allowing connection of the LM-2 Input Module Wall Plates and the BT-1F Bluetooth Audio Wireless Input Module.

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

The MA80E is powered internally via 100-240V SMPS. There is an optional 20mm Flexible Conduit Kit available (CA947034) for fire protection.
