How do I plug my electric guitar into home theater system?
The best way is to have a mixer with a mic input. That way you can adjust the input level and it will output a line level (100mV) signal that can be run to an audio input.
If you don’t have a mixer, one workaround is to use a cassette tape deck with a 1/4-inch mic input. You run the guitar cord to the mic input and run an audio cable from the Playback output for that channel to an audio input on the receiver. Then you press Record and adjust the level of the guitar with the mic input adjustment.
However, you must either have a cassette in the deck and recording when you’re playing, or you have to fool the deck into thinking there’s a cassette in it to be able to actuate the recording circuits and get an output.
When you insert a cassette into a tape deck, small tabs on the spine of the cassette cover small square holes. These push against a lever up in the tape compartment that allows you to record over the tape. If the tabs are popped out, this prevents the tape from being recorded on (if you don’t want to accidentally record over a cassette, you pop out the tabs).
You can usually just stick your finger up into the tape compartment and push the lever in to make the deck think there’s a tape in there. You can then just push Record and then release the lever. The deck should continue in the Record mode indefinitely, since there is no tape in it. If this doesn’t work, you’ll just have to have a cassette in there actually recording while you play.
One other thing I used to do is have the output of a CD player or something run to the line input of the other channel. I would then play along with songs on the CD, using the mic input control as a mixer, so the volume of my guitar on one channel mixes well with the CD music on the other channel. This is basically how I taught myself to play the guitar.
