2.9 4-Channel Configuration

Two dual-mono EVMs can be interconnected using J35 and J36 headers, mounting one EVM on top of another. This enables the evaluation of a total of four audio channels. When two EVMs are interconnected, the following jumper configuration must be considered:

  • Short jumper J42 on one of the EVMs, this jumper is open by default.

In addition to the jumper configurations, verify each amplifier is set for a different I2C address using S1 and S2 on each EVM.
