Hello I have built a diy enclosure and put a 2 channel amp and smps inside and I would like to have 2 inputs. The main input will be a pair of RCA jacks but I would also like to be able to switch to a Bluetooth module when needed. Is there a way I can switch the inputs and also switch the power on to the Bluetooth module at the same time? The BT is powered by it's own 110v to 5v power supply so can be switched via mains power or 5vdc.
