Overview

40W Mini Amplifier

The MA40 is a very compact mono amplifiers designed for integration into audio and AV systems where de-centralised installation is advantageous. It is intended as “install-and-forget” components, and is small enough to be fitted into wall or ceiling voids or in any convenient location adjacent to projectors, flat screen displays or loudspeakers. A simple set of controls and configuration options makes it easy to integrate it 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 MA40 is a mini amplifier providing 40W output at 4Ω (low impedance). It is 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 MA40 is powered via 12-24V external power supply, making it extremely suitable for transport applications, digital signage applications and de-centralised solutions.
