Audio Adaptor + for Analog Discovery 2

[SaltMastering]

The Output side of the Analog Discovery Audio Adaptor I just got doesn’t appear to be working. I get signal at the connector of the AD2. Between W1 and downward pointing arrow ground and W2 and ground. With the Audio Adapter plugged into the connector the Output signal doesn’t make it to either of the output connectors on the Audio Adapter in both jumper positions.

I also have the BNC breakout board and everything works as expected with that. I think the Audio Adapter output section is not working.

Hi @SaltMastering,

You'll need to enable the power supplies for the Audio Adapter + outputs to work. Set both power supplies to have matching outputs greater than 1.5 V in magnitude and enable them so that the amplifier circuitry in the adapter is enabled. There is a bit more detail in the Reference Manual here: https://digilent.com/reference/add-ons/audio-adapter-plus/reference-manual#power.

Let me know if you have any questions.

Thanks,
