PowerLinx iPod accessory sends audio via your existing electrical wiring

Apple StorePowerLinx, Inc., a developer, manufacturer and seller of power line communication products, yesterday announced their 2007 New Product development plans. The four products scheduled to launch in the coming months include: Tune Dog, an iPod/MP3 accessory which will allow the user to send music wirelessly to any room in their home from an iPod, MP3 player or personal computer using only existing electrical wiring; Audio Everywhere, which allows a stereo to send audio through a home’s existing electrical wiring; The Rear Speaker Surround Sound Installation Kit, which allows a surround sound system to send audio to the rear speakers using existing electrical wiring and a new IP Netcam that uses a home’s electrical wiring as a “digital pipeline” to deliver streaming video from up to 6 individual cameras around your home or business using a PC.

“Consumer-based market research is a huge part of our product development process. We have a world class technology division, but that doesn’t mean anything unless we understand our consumer,” said PowerLinx CEO and Chairman Michael Tomlinson, in the press release. “These four new products take advantage of our company’s greatest strengths and we are excited about watching their launch into the marketplace.”

All four new products are targeted at the home and small business consumer. Tune Dog and Audio Everywhere focus on helping music and home entertainment enthusiaists enjoy the things they love even more. No matter where you store your music in your home, Tune Dog will let you send that music through the existing electical wiring in your house to speakers in other locations. Audio Everywhere is designed to enable stereo system users to effortlessly install an additional set of speakers anywhere in their home. The Rear Speaker Surround Sound Installation Kit allows home theatre users send an audio signal from a system to other points in a room without running additional, unsightly wiring. The new IP Netcam is a very cost effective way for a home or office to create a security solution, creating a video network using a single personal computer and the existing electrial wiring in a building.

“We’ve worked very hard over the past 18-months to develop the necessary manufacturing capacity to be successful in the large, fast growing home entertainment markets we are targeting,” added Tomlinson. “An added feature we’ve included in all our new products is that they have been engineered to operate on both domestic and international electrical systems. We see this as a huge advantage as we expand our distribution outside the United States to other potentially profitable markets.”

PowerLinx, Inc. develops, manufactures and markets products and applications that transmit voice, video, audio and data either individually or in any and all combinations over power lines, twisted-pair wires and coax in AC and DC power environments, on any and all power grids. The Company has also developed, manufactured, and marketed different kinds of underwater video cameras, lights and accessories for the marine, commercial and consumer retail markets as well as accident avoidance systems for small and large vehicles.

  1. From what I’ve heard, those gadgets you can get to make a LAN over your wiring are unbelievably flakey, so I wouldn’t be too confident as to this thing’s audio quality…

  2. Also there is a problem with noise interference on Macs from ground loop problems.

    So make sure to install a ground loop isolator as well as regular isolators on your Mac power cord and audio lines respectively if you use this product.

    Basically what a isolator does is make sure that signals only travel down a wire and not up.

    Of course Toslink users need not worry/ ” width=”19″ height=”19″ alt=”smile” style=”border:0;” />

  3. A friend of mine purchased something like that, except it was for extending your LAN through the electrical wiring, and I definitely agree with Tomo; it was so bad, that he ended up returning the product and going back to using wifi.
