“Is the "set up mic" slot where you can plug in an external microphone (primarily for karaoke use)? If not, does the AVR-S540BT accommodate an external microphone? I am assuming the "phones" slot is for audio output only. Thank you.”

• No, the microphone (included) input is used to calibrate the amplifier to the speakers and room characteristics. There is no other microphone input.

• It doesn't have a microphone function. The setup microphone is only for speaker setup and calibration.
