Unfortunately, it's not that easy.
Apparently it's a completely seperate module.
I have pushed and pushed to have RCA outs instead, but unfortunately, for the current target market they decided that having built in power was a better option.
Because of the way the G4 is manufacturered, they will have to make a completely seperate run to include RCA outs instead of built in power.
We are considering ordering a handful of these, but will have to test on one first to make sure the audio is routed accordingly.
I do not have any ETA on when or if this will actually happen. All I can do is continue to let them know my stance on it.
