MATRIX-232 Controller - 1250 Points, 32 Devices ABB

Product Description MATRIX-232

MATRIX-232 is a professional audio matrix processor and amplifier, designed to meet the needs of transmitting and coordinating audio signals in large-scale public address systems. The device allows flexible routing between 32 inputs and outputs, integrating a high-performance DSP processor to balance, mix, and optimize audio quality for each zone.

The system also supports multiple remote control interfaces, easily integrating into audio management platforms or smart buildings. MATRIX-232 is especially suitable for applications such as shopping malls, factories, urban areas, airports, or high-rise office buildings - where stable, clear and easy-to-control sound is required.
