Karaoke machines with audio outputs can be connected to a home theater surround sound system for amplifying the vocalist and accompanying music. A standard set of RCA-type stereo cables with 1/4-inch plugs on each end can be used to connect the karaoke machine to the surround sound receiver in less than a minute. Although the audio will be heard on all speakers connected to the system, it will not be reproduced in multi-channel surround sound unless the source audio for the karaoke machine, such as a CD, was recorded that way.
Insert the red and white plugs on one end of the stereo cables into the audio OUT jacks on the karaoke machine, using the white plug for left audio and the red plug for the right. Some machines feature a set of audio outputs on the front panel; others are equipped with jacks on the back.
Connect the plugs on the other end of the stereo cables to any available set of stereo input jacks on the back of the surround sound receiver, such as an extra set of jacks for a tape deck or an auxiliary (AUX) input.
Plug in and turn on the karaoke machine and surround sound receiver.
Turn the selector knob on the surround sound receiver to the set of jacks that connect it to the karaoke machine.
Disconnect the components from the electricity while hooking up the audio cables.
