OMNITRONIC MTC-3204DSP 4-Channel Power Amplifier with DSP, 4 x 800 W at 4 Ohm, Class D, 1U Rack Mount 10452431

Delivering a formidable 4 x 800 W RMS at 4 ohms from a 1U chassis, the OMNITRONIC MTC-3204DSP redefines power density for professional sound reinforcement. This four-channel Class D amplifier integrates a high-resolution 24-bit DSP engine, enabling precise system tuning without external processors. Ideal for touring racks, fixed installations, and multi-zone audio systems, it combines raw output with advanced loudspeaker management in a single, space-efficient unit.

Overview

The MTC-3204DSP is engineered for demanding live sound and installation environments. Each of its four channels delivers 800 W RMS at 4 ohms or 450 W RMS at 8 ohms, with bridge mode offering a massive 1600 W RMS per channel pair at 8 ohms. The integrated DSP operates at 96 kHz with 24-bit AD/DA conversion, providing crossover, parametric EQ, delay, limiter, gain, and phase controls. A USB port allows connection to a PC for deep editing via software, while the front panel offers essential status LEDs. Inputs are balanced XLR, and outputs use Neutrik Speakon-compatible connectors for reliable, high-current connections.
