How to Connect a Microphone to a Home Receiver so Sound Comes Through the Spreakers

The Moderately Priced Way ($90-$200)

Step 1:
Plug one of your two microphone cables into your microphone and the other end into the input on the microphone pre-amp. Keep the pre-amp switched "off" if there is a power switch.

Step 2:
RCA male to XLR female adapter Plug the other of your two cables into the output of the preamp and into the XLR-female side of your adapter.

Step 3:
RCA (red and white) inputs Plug the RCA male side of your adapter into any one of the audio inputs on the back of the receiver, while the receiver is turned OFF. The Audio inputs will be in pairs, and are red and white RCA connections--use the white (left or mono) connection. If you have a spare "Video" or "Aux," use it, otherwise you may have to disconnect a CD or cassette player temporarily and use its input. DO NOT use any input on your receiver labeled "phono," as this has its own amp and using it risks blowing out your speakers.

Step 4:
Turn the speakers AWAY from the person holding the microphone, or be sure they stand behind the speakers, otherwise you'll experience the pleasures of loud "feedback" firsthand.

Step 5:
Turn down the volume on the pre-amp and the receiver and then turn both units on.

Step 6:
Select the input you've plugged the microphone into (CD or Aux, for example) and turn up the volume on the receiver to a reasonable level. Then, speaking into the microphone, slowly turn up the volume on the microphone pre-amp until you hear your voice coming through the speakers at the level you want.

The audio inputs will be in pairs, and are red and white RCA connections--use the white (left or mono) connection. If you have a spare "Video" or "Aux," use it, otherwise you may have to disconnect a CD player or cassette player temporarily and use its input. Do not use any input on your receiver labeled "phono," as this has its own amp and using it risks blowing out your speakers.
