How to Connect a Microphone to a Home Reciever so Sound Comes Through the Speakers

You can use the "audio in" jacks on your home theater receiver for a wide range of audio experiments. Plug in your MP3 player to listen to music in surround sound. Set up your friend's video game console for an all night gaming marathon. You can even create a faux karaoke bar or backyard PA system with a simple microphone. Some home theater systems may require an adapter for the microphone.

Step

Locate the audio inputs on your home receiver. Most receivers have inputs on the front and back. Usually, the front has a 1/4 inch or 1/8 inch stereo input, a headphone jack. If available, use this jack. Otherwise, locate the most easily accessible RCA (red, yellow, white) input.

Step

Identify the plug on your microphone. Most home-grade microphones have a 1/8 inch plug, similar to what you would see on headphones, or a 1/4 inch plug, a fatter version of the 1/8 inch plug.

Step

Count the stripes on the plug. A plug with two black stripes is stereo (left and right channels). One black stripes denotes mono (one channel).

Step

Determine your adapter needs and purchase the necessary adapter at a local electronics or music store. If the microphone's plug has two stripes and is the same size as the receiver's jack, you don't need any adapters. Plug the microphone into the receiver's audio inputs directly or using the adapter and continue.

Step

Adjust the input selector on your receiver. Usually, the front headphone jack plays over the "Aux" channel. If you're uncertain, slowly move through the selections and speak into the microphone before moving to the next channel. When you hear sound over the speakers, you've found the right channel.
