DDA43

DSPPA DDA43 - network digital amplifier with DSP, 4x450W@4Ω, 4x300W@8Ω, 2x900W@8Ω, 2x900W@100V, 2x612.5W@70V

DSPPA DDA43 is a four-channel Class D IP digital amplifier with advanced DSP processing, designed for professional AV installations in commercial, educational, religious, and public facilities. The device offers power of 4x450W at 4Ω, 4x300W at 8Ω, and in bridge mode 2x900W at 8Ω, 2x900W at 100V, as well as 2x612.5W at 70V.

The built-in DSP processor allows for the configuration of functions such as noise gate, matrix mixer, PEQ (15 on input, 10 on output), crossover (Butterworth, Bessel, Linkwitz-Riley), delay, compressor, and limiter. Control is done via a 2" IPS LCD color display, MConsole software, and through USB, TCP/IP, RS232, RS485, and GPIO interfaces.

The amplifier supports stereo, bridge, mono, and matrix modes. The input sensitivity can be adjusted (0 dBu / 6 dBu) from the screen or software. DDA43 allows for remote monitoring of operating parameters such as temperature, voltage, current, and device status.
