©2003 RadioShack Corporation. All Rights Reserved. RadioShack and RadioShack.com are trademarks used by RadioShack Corporation. OWNER’S MANUAL — Please read before using this equipment. www.radioshack.com SM This wireless transmitter and receiver system use the latest 5.8 GHz technology that travels through walls, floors, ceilings and other obstacles, delivering high quality sound for your home theater system’s rear surround speakers. Using this wireless system, you will experience movie theater quality sound in your own home using your current home theater surround system. We have designed this system for use with your surround sound home theater system to enhance the quality of the sound and balance coming from your speakers. You can now eliminate running long speaker wires through your rooms, while enhancing the sound coming from those speakers. How It Works The transmitter converts the audio signal from your audio source into a 5.8GHz radio frequency and transmits it to the receiver. The receiver will pick up the best signal from one of its two antennas and convert the signal back to its original form. Using a powerful amplifier, the signal is passed to your connected rear surround speakers. The result is an enhanced sound quality resulting in a theater quality surround sound experience. This system is compatible with most audio sources such as televisions, VCRs, stereo receivers/amplifiers, CD players, and personal stereos. This unit allows you to listen to wired speakers in any room in the house when a two-channel source is connected to the transmitter. The audio link system also tracks the volume setting of your audio source, so that when you increase or decrease the volume on the audio source, the link’s connected speakers respond accordingly. Some of this system’s other features include: • 6 user-adjustable channels • 2 diversity receiver antennas for optimal audio reception. • Adjustable speaker and line level input control • 256 option personal ID Code • Ideal for Dolby 5.1 Digital, Pro Logic II, DTS, SCAD and DVD Audio Systems • Provides digital transmission for superb audio clarity • Immunetointerferencefrommicrowave ovens and other popular 2.4GHz equipment • Signal range of 30 feet RECEIVER TRANSMITTER STANDBY / ON/OFF —Press to toggle between standby mode and power on. LED —Lights red when the transmitter is in power on mode, and turns green when in standby mode. POWER/PUSH OFF — Press to power the receiver on or off.
