DDA23

DSPPA DDA23 - network digital amplifier with DSP, 2x450W@4Ω, 2x300W@8Ω, 1x900W@8Ω, 1x900W@100V, 1x612.5W@70V

DSPPA DDA23 is a professional, multifunctional network amplifier with advanced DSP processing, designed for demanding fixed installations in commercial, educational, and public spaces. The device offers a power of 2x450W at 4Ω, 2x300W at 8Ω, while in bridge mode 900W at 8Ω, 900W at 100V, and 612.5W at 70V.

The built-in DSP engine allows real-time configuration of functions such as compressor, limiter, noise gate, PEQ correction, matrix mixer, delay, and FIR filters (4/8x1024 taps). The optional Dante input (4 channels) enables audio signal and control data transmission over a single RJ45 cable.

Control is done via a color IPS LCD display, MConsole software, and through USB, TCP/IP, RS232, RS485, and GPIO interfaces. The amplifier supports stereo, bridge, mono modes, and any matrix configuration. Input sensitivity can be adjusted (0 dBu / 6 dBu) from the screen or software.
