Hello,
  Can I swich audio input or output on relay attenuator? It is possible choose between RCA input and onboard input from Piano or Boss DAC? And similarly for output - RCA output and onboard output to Volt Amp. Thanks

Hi,

    Can I swich audio input or output on relay attenuator?

Can you provide more details on above query.

     Now the setup is working with onboard connectors (From DAC to Attenuator and From Attenuator to Volt Amp). There is no switching between the RCA connectors and onboard connectors. If you go with RCA connectors(Input & Output) of attenuator, then you have to make the attenuator as the stand alone. but in this case you have to connect some control gpio’s from the Piano or BOSS DAC through external cabling or wiring. And the same way you have to connect the RCA output to VOLT AMP.

With Regards

Thank you for your reply. Now I see, I can't connect Boss DAC and CD Player via RCA to relay attenuator at same time. Do you think about make another audio HAT for Raspberry Pi whitch can switch audio input from DAC and AUX RCA?
