Biamp MA30 30W 1-Channel Mixing Amplifier

The MA30 is a compact, half-rack 30-watt single-channel mixing amplifier built for installations that require dependable performance in a small form factor. Front-panel microphone and volume controls make operation straightforward, while Class D amplifier technology ensures efficient, clean audio output. Its design provides immediate visual feedback and user-friendly operation, making it ideal for both experienced and casual operators.

With four levels of audio routing priority, the MA30 includes a dedicated emergency input with mute-all function, a paging mic with contact closure and chime, one mic/line input with 48V phantom power, and two stereo line inputs. Fanless cooling, auto-standby mode, and a universal power supply support long-term reliability and energy efficiency. Compact yet powerful, the MA30 is well-suited for paging, announcements, and background music in environments such as offices, retail shops, hospitality spaces, and classrooms.
