The CMX DST-2120, DST-2240, DST-2350 and DST-2500 2-Channel DSP Power Amplifiers are designed for professional PA and commercial audio projects that need reliable amplification with precise loudspeaker management. They are suitable for auditoriums, conference halls, hotels, educational institutions, houses of worship and other Bangladesh installations where installers need flexible speaker outputs and advanced DSP control from a compact rack-mounted amplifier.

The series provides output capacities from 2×120W up to 2×500W, depending on the model, and supports 100V, 4Ω and 8Ω speaker systems. Mono, free-matrix, stereo and bridge operating modes provide flexibility for different system configurations.

Built-in DSP gives installers control over PEQ, crossover, delay, limiter, gain, high-pass and low-cut filtering. With 31 input PEQs, 10 output PEQs and 30 DSP presets, the amplifier can be optimized for different loudspeaker and room requirements. A front-panel USB Type-C port and RS232 control support convenient configuration and system management.

The 320×240 IPS LCD display, professional protection circuitry and optional Dante or AES67 network modules make this CMX series a practical solution for modern commercial and professional sound installations.
