3000W Peak 2-Channel Power Amplifier Board

This 2-channel power amplifier board supplies the amplification stage for a custom pro audio or DJ build. It puts out 250W RMS per channel into 8 ohms, 400W RMS per channel into 4 ohms, and 800W RMS bridged into 8 ohms, with peak output of 1000W per channel at 8 ohms, 1500W per channel at 4 ohms, and 3000W bridged. That range covers a pair of passive full-range tops in a small room through to a single high-demand subwoofer cabinet running bridged.

Frequency response spans 20Hz to 20kHz within +/- 0.5dB, so low-end material stays defined and highs stay clean across the audible band. Distortion measures under 0.03% and the signal-to-noise ratio exceeds 102dB, which keeps the noise floor low during quiet passages and between tracks. Inputs accept balanced sources at 20K ohms and unbalanced sources at 10K ohms, so the board drops into a mixer, crossover, or DSP output without an impedance mismatch.

The board measures 10 x 8 x 3.54 inches and weighs 2.19 lb, leaving room to mount it in a rack chassis, a powered speaker cabinet, or a custom amp enclosure. It runs on 120V, 50-60Hz power.

This is a bare board built for DIY work. Wiring, heat management, and enclosure work are up to you, which makes it a fit for techs repowering an existing cabinet, integrators assembling a fixed-install rack, or anyone building a DJ amp from parts. If you are not experienced with audio amplifier wiring and high-voltage work, have a professional handle the install.
