Re: U3S Output #u3s

Phil Crockford

Yes I have done it. It involves a board with relays driven from the B0 - B5 outputs on the U3S board. Each relay controls the amount of Bias on the PA transistor via a potentiometer, one for each of the outputs.
It works well. If you want diagram and notes let me know.

No doubt there are other ways of doing it but this was done with what i has in my box.
