Surround sound speakers can be liberated from speaker cables to eliminate clutter and increase placement options by connecting an audio receiver and transmitter kit to the system. A radio transmitter wired to the audio-video receiver's speaker terminals sends the signal to a receiver attached to each surround sound speaker, eliminating long wire runs across the room. Speakers can be quickly moved outdoors, to a patio or another room, depending on the transmission strength of the wireless equipment.
Cut two short lengths of wire, about six inches, for each speaker that will be converted to wireless. Strip 1/2 inch of plastic insulation from the two wires on each end.
Attach the two wires to the two red and black terminals on the rear of each surround sound speaker. Some terminals have levers that raise on springs to reveal the wire connector holes underneath. Other terminals twist counter-clockwise to expose the bare-metal post underneath for wrapping the wire.
Connect the two wires on the other end to the terminals on the receiver unit, matching the wire from the speaker's positive (red) terminal to the positive terminal on the receiver. Adjust the antenna on the receiver by rotating upright.
Attach another short length of speaker wire to the output terminals for the surround sound speaker on the back of the AV receiver. Match the wires on the other end to the terminals on the wireless speaker transmitter that comes in the kit, connecting positive to positive and negative to negative. Adjust the antenna on the transmitter.
Place the left surround sound speaker and connected receiver on the left side of the room. The receiver will be labelled "L" or "Left" on the back panel. Set the right surround speaker on the right side of the room.
Plug in the electrical cords for the transmitter and wireless speaker receivers. Operate the home theatre AV receiver normally.
Many wireless speaker kits come with a transmitter with two sets of terminals for a pair of surround sound speakers and two receivers for connecting a pair of speakers. Use additional kits to expand the wireless system.
Prevent a speaker-damaging power surge by connecting all audio wires before plugging the receivers and transmitters into the electricity.
