Overview

70/100V 80W Mini Amplifier with Facility Port

The MA80FT 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 MA80FT provides 80W Mono Output at either 4Ω (low impedance) or 70/100v line which is switchable via rear Dip switches. It is fitted with a paging Microphone input with access contacts, a useful 70/100v line input a futher 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 MA80 is powered internally via 100-240V SMPS. There is an optional 20mm Flexible Conduit Kit available (CA947034) for fire protection.
