A Number Of Recommendations To Help Decide On A Wireless Surround Sound Set
The latest range of wireless surround sound transmitter devices claims streaming of music throughout the home without limits. We will investigate if these latest devices are suitable for whole-house audio. Also, we will give crucial guidelines for selecting a wireless audio system.
Infrared products send the audio as lightwaves. Light can't go through walls. For that reason products using infrared, such as wireless surround sound kits, 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 consequently easily transmit through walls. FM transmitters are the cheapest option. They provide decent range but the music signal is prone to audio distortion and static and is very susceptible to interference from other wireless transmitters. Digital wireless audio transmitter products, such as products from Amphony, use a digital protocol. The audio is first converted to digital data before being broadcast. This method ensures that the audio quality is fully preserved. Some transmitters utilize some type of audio compression, such as Bluetooth transmitters, which will degrade the audio to some degree. Transmitters which send the audio data uncompressed will attain the highest fidelity.
Products using wireless LAN are practical when streaming audio from a PC. Their disadvantage is that they normally have some fairly high latency, i.e. the signal will be delayed by some amount since wireless LAN was not specifically designed for real-time audio streaming. WLAN receivers typically require buying a separate LAN card to be plugged into each 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. Also, a number of products require to buy separate wireless LAN modules that are plugged into each audio receiver.
Here are some suggestions for selecting the optimum 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 buy extra transmitters when you begin adding receivers in different rooms of your house. Some devices have some sort of error correction built in which will help guard against dropouts in case of strong wireless interference. Select a digital RF audio transmitter to ensure that the audio quality is preserved. Make sure the audio delay is less than 10 ms if you have a real-time application such as video.
Make sure the wireless transmitter provides the audio inputs you require. You may need amplified speaker inputs, RCA audio inputs etc. Choose a system where you can add receivers later on which provide all of the necessary outputs, e.g. amplified speaker outputs, RCA outputs etc. If you go with a digital audio transmitter, choose one with an input audio level control knob to avoid the music signal from clipping inside the transmitter audio converter. This will ensure optimum dynamic range regardless of the signal level of your equipment.
Choose a transmitter that has all of the audio inputs you need, e.g. speaker inputs, RCA inputs etc. Make sure that you can buy additional receivers later on as you expand your system. Verify that you can get receivers with speaker outputs for connecting regular loudspeakers as well as receivers with line-level RCA outputs. Select a transmitter that can regulate the audio volume of the input stage. This will give you the versatility to connect the transmitter to any type of equipment with different signal levels. Otherwise the audio may get clipped inside the transmitter converter stage or the dynamic range is not fully utilized. Check that the amplified wireless receivers contain built-in digital amplifiers with low distortion figures. This will keep the receiver cool due to high amplifier power efficiency and offer optimum sound quality. Check that the amplified receiver is able to drive speakers with the preferred Ohm rating and that it is small and easily mountable for simple set up. 5.8 GHz wireless devices typically have less problems with interference from other wireless transmitters than devices operating at 900 MHz or 2.4 GHz.
