7.1CH Decoder DA32VB User Manual

  • Model: DA32VB

  • Outline dimension: 115x90(mm)

 

   Feature
  • Four digital inputs and one analog input, users can extend analog input on your own.
  • 7.1 analog audio input, built-in third-order low-pass filter amplifier circuit.
  • Adopt CS4926 series audio DSP, CS8415 96KHz digital receiver, 96 KHz/24bit ADC and DAC.
  • Support Dolby digital, Dolby pro-logic, DTS, and so on, with many kinds of listening modes and sound field effect playbacks.
  • Built-in analog input mute, when there is no analog signal, the muting process will automatically go on without stop, and there is no need to connect detection circuit outside.
  • Digital and analog ground wires are independent, which lowers the requirement of motherboard PCB LAYOUT and gets better performance.
  • Provide mute control signal output and directly use hardware to mute.
  • STL212 MCU can upgrade directly program online. Users can get new program on Internet when necessary, which provides convenience for debugging and maintenance.
  • 17 universal output ports, it is okay to use built-in CPU to complete whole machine functions.
  • Use I2C slave interface to connect user host, and it is okay to use existing I2C interface without adding additional interface.
  • I2C interface can be used with another I2C device in parallel. DA32VB is the same as many I2C devices such as 24C01 and so on, and it’s easy for users to do secondary development.
  • I2C communication has TNT interrupt output port, user host can read corresponding data when TNT changes, which reduces the holding time of user host communication.
  • Built-in 60 bytes memory space, its function is the same as 24C01, and there is no need for users to use memory chips such as 24C01, 93C46, and so on any more.
  • Provide software development kit SDK source code, it is convenient for users to do secondary development.
