2.8 4-Channel Configuration

Two dual-mono EVMs can be interconnected using J75 and J76 headers, mounting one EVM on top of another. This enables the evaluation of a total of 4 audio channels.

When 2 EVMs are interconnected, the following jumper configuration must be considered:

  • Short jumper J51 on one of the EVMs, this jumper is open by default.
  • Open jumpers J19 and J20 on both EVMs, these jumpers are shorted by default.

In addition to the jumper configurations, make sure each amplifier is set for a different I2C address using S2 and S3 on each EVM.
