Digital Audio Processor 8 In 8 Out

  • Highly integrated, integrating a variety of traditional Analog audio processing equipment in a Digital audio processor;
  • High-performance 32-bit floating-point DSP processor, all-digital processing, fast response to Acoustic Feedback Cancellation, Acoustic Echo Cancellation, Adaptive Noise Cancellation and other core algorithms;
  • High-performance A/D, D/A converter, 24bit/48KHz sampling frequency, high-quality Analog → Digital, Digital → Analog conversion;
  • 8 Analog input channels and 8 Analog output channels, very small distortion and ultra-low background noise;
  • Rich interface expansion;
  • Humanization, graphical, intuitive and easy-to-operate control software interface;
  • Comprehensive matrix mixing functions;
  • Scene storage is different from the Analog equipment is one of the most practical and significant features, can store 100 complete scenes, all the scenes can be exported to an external storage device for storage backup, so that the later call at any time.
