Description

The MA40E is a mini amplifier providing 2 x 20W Stereo Output at 4Ω (low impedance). It is fitted with an Ethernet and RS232 interface, two line inputs and a facility port input option allowing connection of the LM-2 wall input module and the new Cloud 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 MA40E is powered via a 12-24V power supply and offers music mute functionality to allow simple connection to fire alarm and other interfaces and provides a great bridge between centralised and de-centralised solutions.
