Various Recommendations To Help Select A Wireless Surround Sound Kit
The newest series of wireless surround sound transmitter products claims streaming of music throughout the home without limits. We will take a look at the most widespread technologies for wireless audio and give some advice for selecting the best wireless audio product.
Infrared is limited to line of sight since the audio signal is sent as lightwaves and therefore products utilizing this technology, such as infrared wireless surround sound products, are limited to a single room.
RF wireless products broadcast the audio as RF waves - either by utilizing FM transmission or digital transmission - and can as a result without problems transmit through walls. FM transmitters are the cheapest option. They provide good range but the music signal is prone to audio distortion and hiss and is very susceptible to interference from other wireless transmitters.
Digital wireless audio transmitter products, such as products from Amphony, utilize a digital protocol. The audio is first converted to digital data before being broadcast. Some wireless audio transmitters will utilize audio compression, such as Bluetooth transmitters which will lower the audio quality to some extent. Digital wireless audio transmitters which send the audio uncompressed offer the highest audio fidelity.
Wireless LAN (WLAN) products are useful when streaming from a PC but will add some amount of latency or delay to the signal because wireless LAN was not originally designed for real-time audio streaming. WLAN receivers usually require buying a separate LAN card to be plugged into each receiver.
Powerline products utilize the power mains to distribute music and offer great range but run into trouble if there are separate 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 usually build a delay of several seconds into the transmission.
Here are some pointers for selecting 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 additional transmitters when you begin adding receivers in different rooms of your home. Some products have some sort of error correction built in which will help guard against dropouts in case of strong wireless interference. Digital RF audio transmitters will be able to maintain the original audio quality. If you have time-critical applications where sync of the audio is important then you should get a transmitter with a low audio latency. An audio latency of less than 10 ms would be suitable for most scenarios.
For high amplifier power efficiency and greatest sound quality, confirm that the amplified receiver has a built-in low-distortion digital amplifier. Choose a system which offers 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 set up. Devices which function in the 5.8 GHz frequency band will have less trouble with wireless interference than devices using the crowded 900 MHz or 2.4 GHz frequency band.
