Listen to streaming audio and Internet downloads through your home stereo system with Jensen's Matrix wireless Internet audio transmitter. Use this transmitter to listen to digital audio files (including MP3, WAV, and VQF formats) with superior sound quality and control. The Matrix's 900 MHz signal travels through walls and floors to deliver quality stereo sound virtually anywhere in your home with a range of up to 150 feet.
This kit contains the wireless transmitter and receiver, two AC adapters, and a stereo Y adapter. To install, just hook the transmitter and receiver up to their respective AC adapters and plug them into wall outlets. Use the stereo Y adapter to link your computer sound card's speaker output and the transmitter. Use the tuners to fine-tune the transmitter and receiver for optimum sound, then sit back and listen.
The manufacturer notes that both the transmitter and receiver do not have on/off switches, so you may want to unplug them if not in use for a long period of time. This product comes with a one-year limited warranty.
