Zapco ST-6X DSP III アンプ 6チャンネル Class AB 8チャンネルDSP搭載 6x100W

The signal delay feature was exactly what I needed to align my rear fill speakers with the fronts. Clean, clear output at 100 watts per channel with zero distortion so far.

Having the DSP on each channel lets me dial in the sound for my mids and subs separately, and the class AB power stays clean even when I push the gain. Running 6x100w with the built-in crossovers made my bi-amp setup dead simple.

The phase control and signal delay options let me fix my rear stage timing perfectly, and 6x100w is plenty for my mids and tweets. Took an afternoon to tune, but the DSP software makes it pretty straightforward once you get the hang of it.
