DDA43D

DSPPA DDA43D - network digital amplifier with DSP and Dante, 4x450W@4Ω, 4x300W@8Ω, 2x900W@8Ω, 2x900W@100V, 2x612.5W@70V

The DSPPA DDA43D is a four-channel Class D digital amplifier with full IP network support, advanced DSP processing, and a 4-channel Dante input. The device offers power of 4x450W at 4Ω, 4x300W at 8Ω, and in bridge mode: 2x900W at 8Ω, 2x900W at 100V, and 2x612.5W at 70V. It also supports constant voltage outputs of 70V/100V (900W @ 10Ω), making it an ideal solution for modern AV installations in commercial, educational, and public facilities.

The built-in DSP processor allows 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 / 6 dBu) from the screen or software. The DDA43D allows remote monitoring of operating parameters such as temperature, voltage, current, and device status.
