Main feature
DSP4X8 is an advanced 4 input 8 output digital audio signal processor. It uses the most suitable high-performance parts to achieve the best audio results with the lowest distortion and noise. DSP4X8 uses a 40-bit floating point DSP processor as the central processing, greatly improving the dynamic range of signal processing, many times higher than the 24 bit design quality. This design is also the most advanced audio processor design available today. DSP48 has a friendly, easy to use user interface. It provides maximum control and flexibility in input/output signal control. The DSP4X8 can be connected to the RS232 interface of the computer through the included software and can provide a central control code.
