Overview

40W Mini Amplifier with 70/100 V Line Input

The MA40F 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 MA40F is a mini amplifier providing 40 W Output at 4 ohms (low impedance). It is fitted with a paging microphone input with access contacts, a useful 70 / 100 V line input option, a further two line inputs and a facility port input option allowing connection of the LM-2 wall input module and the Cloud BT-1F Bluetooth Audio Wireless input module.

The MA40F is powered via a 12 - 24 V power supply and offers music mute functionality to allow simple connection to fire alarm and other interfaces which makes it highly flexible and suitable for use in themed/visitor attractions including use in bus / tram / river tour guide systems.
