Product Overview

The Biamp Commercial MA120 is a 120-watt mixing amplifier with an intuitive front and rear panel. A prominent, illuminated volume control sits at the forefront, while the mic volume control is smaller and recessed. This Class-D mixing power amplifier supports 4-ohm and 70V/100V outputs and offers balanced mic inputs alongside four mono line, mono-summed inputs.

Product Description

The MA120 delivers a single channel of 120 watts of continuous power and provides four priority levels for audio routing. A 24V priority output overrides local volume controls, and a dedicated emergency input with a mute-all switch supports notification scenarios. It includes a paging mic input with contact closure and chime, two mic/line level inputs with 48V phantom power, and four stereo inputs. The amplifier features fanless operation, an internal universal power supply, an auto standby mode, and 2RU rack mounting.
