Basing on the high efficient, high power, and stable switching power supply of the Class D amplifiers, Gisen add DSP into these amps to make them better.
So far we have 2 kinds of DSP, one is with big touch-screen DSP, and the other is with DSP made in German.
With big touch-screen DSP is the DSP series, while with German DSP is the K-DSP and M-DSP series.
