The CMX DSP-4120 is a professional 4 Channel Class-D Power Amplifier delivering 4 × 120W RMS output, designed for advanced public address (PA) systems and professional networked audio installations. Featuring Digital Signal Processing (DSP), Dante audio networking, and GPIO control, it delivers outstanding sound quality, efficient power performance, and flexible multi-channel audio distribution.

Supporting both 100V constant-voltage and 8 Ohm low-impedance speaker systems, the DSP-4120 is compatible with a wide range of commercial speaker configurations. The built-in DSP provides advanced audio processing, including equalization, crossover management, limiting, and system optimization for superior sound performance. Dante networking enables low-latency, high-quality digital audio transmission over standard Ethernet infrastructure, while the integrated GPIO interface allows seamless integration with external control and automation systems.

Housed in a compact 1U rack-mount chassis, the DSP-4120 is ideal for conference centers, hotels, educational institutions, hospitals, shopping malls, office buildings, airports, stadiums, and other commercial environments requiring reliable multi-channel audio amplification.
