Hi,
I've just connected a Tinysine Bluetooth Receiver via RCA to one of the inputs on the back of my NAD 32 stereo amp. Now whenever I change inputs on the amp my speakers pop once. If I take the power out of the BT the amp changes input as normal. I tried powering the BT from a USB port in my laptop and then from a normal wall wart (5v, 1amp).
Is this a ground loop or something else? Any suggestions on troubleshooting most welcome!
