Various Tricks To Help Select A Cordless Surround Sound Set
The latest series of wireless surround sound transmitter devices claims streaming of music throughout the home without limits. We will look at different products and technologies to find out in how far these devices are useful for whole-house audio uses and what to look out for when purchasing a wireless system.
Infrared wireless audio devices are limited to line-of-sight applications, i.e. only work within a single room since the signal is sent as infrared light which can't go through walls. This technology is frequently found in wireless speaker kit products.
Infrared is restricted to line of sight because the audio signal is broadcast as lightwaves and therefore products using this technology, such as infrared wireless surround sound products, are restricted to a single room. RF wireless products will broadcast the signal as RF waves. These waves can without problems go through walls. RF wireless audio devices either make use of FM transmission or digital audio transmission. FM transmission is inexpensive but rather prone to static, audio distortion and susceptible to interference.
WLAN products are useful for broadcasting audio from a PC. However, wireless LAN was never designed for real-time audio streaming. As a consequence, products utilizing WLAN will introduce some amount of delay to the signal. WLAN receivers often do not have built-in network access. As a result, such products frequently require purchasing separate LAN cards. These cards are then plugged into every receiver.

As a result, products using WLAN will introduce some amount of delay to the signal. WLAN receivers usually require purchasing a separate LAN card to be plugged into each receiver.
Powerline products use the power mains to distribute music and offer great range but run into trouble if there are individual mains circuits in the home in terms of crossing between circuits. Another problem facing powerline products are strong power surges and spikes. Such surges can cause dropouts in the audio due to errors in the transmission. To safeguard against these errors, powerline products typically build a delay of several seconds into the transmission.
Here are some guidelines for picking the perfect wireless audio system: Try to find a system that can run several wireless receivers from a single transmitter. Ideally an unlimited number of receivers should be supported. That way you don't need to purchase extra transmitters when you begin adding receivers in several rooms of your home. Picking a product with some sort of error correction will help mitigate against strong RF interference. Such interference can be brought on by other wireless transmitters. Choose a digital RF audio transmitter to make sure that the audio quality is preserved. Make sure the audio latency is less than 10 ms if you have a real-time application such as video.
Ensure that the amplified wireless receivers have built-in digital amplifiers with low distortion figures. This will keep the receiver cool due to high amplifier power efficiency and provide optimum sound quality. Choose a system which provides receivers that can drive speakers with the desired Ohm rating. Make sure the receivers have a small form factor and are easily mountable. This will help during the installation. 5.8 GHz wireless products usually have less problems with interference from other wireless transmitters than devices operating at 900 MHz or 2.4 GHz.
