London Power 3 channels amplifier project
#12
Hi Vostre

Your figure shows conceptually what the 7211 does, but it looks like a DPDT and needs a jumper on the back to have this functionality - otherwise it defaults to the pick-up selector function.

Also, because the relays have two states, you have to decide on what the default state selects channel-wise, i.e.e, no relays on = clean, but could just as easily be over-drive. It depends also on what aesthetic you want for the switch positions, which are in a fixed order mechanically, but you can assign the result as "increasing gain" or whatever, if that is clear?
