On my K7BT, I do not hear a relay inside when turning the unit on or switching inputs, but I am used to audio equipment having relays inside that I can hear. I am guessing relays provide a better internal connection (audio path) than some sort of digital/transistor switch.This is normal operation. What you are hearing is the relay switch for your particular input being "engaged/activated".
