DSP48

Digital Signal Processors

DSP48, an advanced Digital audio signal processor with four input and eight output, adopts the most suitable devices of high performance to ensure the best effect,the lowest distortion and noise. DSP48 adopts floating - point DSP processor with 40 bits as central processing unit whose design quality is many times higher than that of 24 bits improving greatly the dynamic range of signal processing, it is also the highest design in current audio processor. DSP48 has friendly and easy - to - use user interface, providing maximum control and flexibility to Input and Output signal control. DSP48 can provide the central control code and connect computer's RS232 interface through accessary software.

FEATURES

  • Four input channels of signals, eight output channels of signals.
  • 40 bits floating - point DSP chip.
  • 96K sampling rate 24 bits high speed A/D D/A transform.
  • 1Hz frequency accurate positioning.
  • Each input channel allocating 31 segments GEQ.
  • Each input and output channel allocating eight Parametric Equalizer (PEQ), all of which are +15dB gain and -30dB attenuation, Q value form 0.01 to 2.50.
  • Super quality of audio signal processing.
  • The CPU kenel program can upgrade continuously.
  • Each input channel and output channel have the mute switch (with lamp display).
