Several Tricks To Help Pick A Wireless Surround Sound Kit
The latest series of wireless surround sound transmitter devices claims streaming of music throughout the home without limits. We will research if these newest devices are suitable for whole-house audio. Also, we will give vital suggestions for choosing a wireless music system. Getting audio from your living room to your bedroom can be quite a problem particularly in buildings which are not wired for audio. There are several technologies solving this problem. These include infrared wireless, RF wireless, wireless LAN (WLAN) and powerline.
Infrared wireless audio devices are restricted to line-of-sight applications, i.e. only operate within a single room because the signal is broadcast as infrared light which can't penetrate walls. This technology is often found in wireless speaker kit products.
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 offer 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 devices, such as products from Amphony, use a digital protocol. The audio is first converted to digital data before being transmitted. This method guarantees that the audio quality is entirely maintained. Some transmitters use some sort of audio compression, such as Bluetooth transmitters, which will degrade the audio to some extent. Transmitters which send the audio data uncompressed will achieve the highest fidelity.
Digital wireless audio transmitter products, such as products from Amphony, use a digital protocol. The audio is first converted to digital data before being transmitted. This method guarantees that the audio quality is entirely preserved. Some transmitters utilize some form of audio compression, such as Bluetooth transmitters, which will degrade the audio to some extent. Transmitters which send the audio data uncompressed will attain the maximum fidelity.
Powerline products send the audio by means of the power mains and provide great range. They run into problems in homes where there are separate mains circuits in terms of being able to cross over into another circuit. Powerline products have another problem in the form of power surges and spikes which can cause transmission errors. To avoid audio dropouts, these products will normally have an audio latency of several seconds as a safeguard.
Here are some suggestions for selecting a wireless audio system: If you plan to stream audio into numerous rooms of your home, be sure to select a system that permits streaming to several receivers at the same time. That way you don't have to buy a separate transmitter for each receiver that you are streaming to. Some products have some form of error correction built in which will help guard against dropouts in case of strong wireless interference. Pick a digital RF transmitter to maintain the original audio quality, preferably one with an audio latency of less than 10 ms in case of video or other time-sensitive applications.
Select a transmitter that has all of the audio inputs you require, e.g. speaker inputs, RCA inputs etc. Choose a system where you can add receivers later on which offer all of the required outputs, e.g. amplified speaker outputs, RCA outputs etc. Since you may want to connect the transmitter to several sources, you should select a transmitter that can be adjusted to different signal volume levels to prevent clipping of the audio signal inside the transmitter converter stage.
Make sure 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 maximum sound quality. Pick 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. Devices utilizing the less crowded 5.8 GHz frequency band will generally have less trouble with wireless interference than 900 MHz or 2.4 GHz products.
