inDESIGN BMA 120 – 100V Mixer Amplifier (120W)

The inDESIGN BMA 120 is a dependable, commercial-grade mixer amplifier designed for retail, hospitality, education, offices, and industrial audio installations. Built for clarity, reliability, and easy integration, it delivers 120W of output power with the flexibility of 4 Mic/Line inputs, selectable 4–8 Ω low-impedance output, or 70V/100V constant-voltage speaker lines.

Input 1 includes a priority mute (VOX) so paging announcements can automatically override all other inputs—ideal for venues needing clear communication and background music control. A pre-amp out / power-amp in link is provided, allowing simple connection to an external equaliser or booster amplifier for system expansion.

As part of the inDESIGN Install Series, the BMA 120 offers excellent performance, reliability, and value for fixed installations.
