In the past, due to the lack of chips for the DSP module, Sinbosen's touch screen DSP series power amplifiers stopped production for a while. Now the modules are sufficient, and they are starting to sell again. The touch screen DSP is favored by customers for its simple touch screen operation and software operation. The article briefly introduces this DSP module.

Technical Features:

1. 4 single track input, 4 single track output, plus GPIO control.

2. 4 inch resistive touch screen.

3. 96KHz sampling frequency, 24bit A/D & D/A converter, 32 bit floating point DSP chip.

4. With professional PC software, real-time remote control by USB or RS485.

5. 4 channels input and output, output matrix model sets freely.

6. Output: Mute, 8 bands EQ, X-over, Input Source optional, Polarity,Delay, Limiter, Gain (Max Delay 1s; frequency point, slope size and slope form of X-Over adjustable; frequency point, gain and band width of EQ adjustable, with PEQ, Hi-Shelf and Lo-Shelf three optional models)
