How To Convert Your Speakers Into Wireless SpeakersRunning speaker cable through your home for setting up speakers can be a hassle. As an alternative to running long cables, several companies are offering solutions that can turn your speakers into wireless speakers. In this review I will glance at a few of those products.
The first type of products are audio transmitters. These kits usually include a transmitter base that connects to an audio source such a CD player, PC sound card or MP3 player via cable. The signal is then converted to wireless and streamed to a remote wireless receiver. The receiver will output the audio to a power amplifier. These transmitters differ in range depending on the wireless technology. Bluetooth transmitters use this well established wireless protocol. However, Bluetooth transmitters have a fairly low range. Transmitters using a proprietary protocol have much better range. One common shortfall of these products is the fact that they need an external power amp to drive a speaker.
The second group of products is called "wireless speaker kit" or "wireless surround sound kit". These products are available on the web at http://www.amphony.com/products/wireless-surround-sound.htm as well as several HiFi retailers. These kits differ from audio transmitter products in that the wireless receiver unit includes a power amplifier and can directly drive a speaker.
