Description

The MA40 is a mini amplifier providing 40W Mono 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.

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

The MA40 is powered via 12-24V external power supply, offers negative earthing, making it extremely suitable for transport applications, digital signage applications and de-centralised solutions.
