A Number Of Secrets To Help Select A Wireless Surround Sound Set
Getting audio from your living room to your bedroom can be quite a problem in particular in homes which are not wired for audio. The following technologies are used by products solving this problem: infrared, RF, wireless LAN and powerline.
Infrared is limited to line of sight because the audio signal is broadcast as lightwaves and for that reason devices utilizing this technology, such as infrared wireless surround sound products, are limited to a single room.
RF wireless products send the music as RF waves - either by using FM transmission or digital transmission - and can as a result easily transmit through walls. FM transmitters are the cheapest option. They offer decent range but the audio signal is prone to audio distortion and static and is very susceptible to interference from other wireless transmitters.
Products utilizing wireless LAN are practical when streaming audio from a PC. Their drawback is that they generally have some fairly high latency, i.e. the signal will be delayed by some amount since wireless LAN was not particularly designed for real-time audio streaming. Also, some products require to buy separate wireless LAN modules that are plugged into each audio receiver.
WLAN products are practical 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 frequently do not have built-in network access. As a result, such devices frequently require buying separate LAN cards. These cards are then plugged into every receiver.
Powerline products use the power mains to distribute music and offer large range but run into trouble if there are individual mains circuits in the home in terms of crossing between circuits. Another challenge facing powerline products are strong power surges and spikes. Such surges can bring about dropouts in the audio due to errors in the transmission. To safeguard against these errors, powerline products normally build a delay of several seconds into the transmission. Here are some tips for picking a wireless audio system: If you plan to stream audio into numerous rooms of your house, be certain to go for a system that permits streaming to several receivers at the same time. That way you don't have to purchase a separate transmitter for each receiver that you are streaming to. Products with some type of error correction will be more immune against radio interference from other wireless transmitters. Pick a digital RF audio transmitter to ensure that the audio quality is maintained. Make sure the audio latency is less than 10 ms if you have a real-time application such as video.
Select a transmitter that has all of the audio inputs you require, e.g. speaker inputs, RCA inputs etc. Get a wireless system where you can purchase additional receivers later on. You should confirm that you can get receivers for all the different applications you have. Such receivers may include amplified receivers for passive speakers or line-level receivers for active speakers. Given that you may want to connect the transmitter to several sources, you should pick a transmitter that can be adjusted to different signal volume levels to prevent clipping of the audio signal inside the transmitter converter stage.
For high amplifier power efficiency and best sound quality, verify that the amplified receiver has a built-in low-distortion digital amplifier. Choose a system that provides receivers that can drive speakers with the preferred Ohm rating. Make sure the receivers have a small form factor and are easily mountable. This will help during the installation. Devices using the less crowded 5.8 GHz frequency band will normally have less problems with wireless interference than 900 MHz or 2.4 GHz devices.
