2.1 Setup

Software Control Mode

  1. Connect speakers to TAS5827EVM.
  2. Connect a PSU to the TAS5827EVM and turn on the power.
  3. Plug in a USB cable from the PC to the TAS5827EVM. The USB READY LED (Blue) is also illuminated.
  4. If an optical source is used, then he blue SPDIF LOCK LED is illuminated.
  5. Make sure jumpers configuration are correct with the appropriate mode:

    J11SCL/HW_SEL1OUT1-2 or 2-3 as needed

  6. Initialize the TAS5827 device using PPC3 to begin playing audio and testing the different features.

Hardware Control Mode

  1. Connect speakers to TAS5827EVM.
  2. Make sure jumpers configuration are correct with the appropriate mode: See Table 3-1 and Table 3-2.
  3. Configure S2 to SPDIF input source.
  4. Note, that in Hardware Control mode or some configurations, the appropriate resistors needs to be modified on the EVM.
  5. Connect a PSU to the TAS5827EVM and turn on the power.
  6. If an optical source is used, the blue SPDIF LOCK LED is illuminated.
