DS458/DS356/DS254 Network DSP audio processor


  • Build-in Digisyn-Link network audio model. Support AES 67 standard with 4 inputs and 4 outputs, a maximum of 16 signal outputs in one channel. Delay memory could be set with 1ms, 2ms, 4ms.
  • High-performance AD/DA DAC chip and high-speed processing DSP chip.
  • Delay IS for each input and IS for each output.
  • Input 7-band PEQ and Output 7-band PEQ.
  • Accessibility Design (Digital lock, Copy, Routing, etc.)
  • Support USB/RS485 communication. This could be applied to different environments
