Several Secrets To Help Select A Wireless Surround Sound Kit The latest series of wireless surround sound transmitter devices promises streaming of music throughout the house without limits. We will take a look at numerous products and technologies to find out in how far these products are practical for whole-house audio uses and what to look out for when buying a wireless system.
The latest series of wireless surround sound transmitter products claims streaming of music throughout the house without limits. We will take a look at the most common technologies for wireless audio and give some recommendations for choosing the best wireless audio product.
Infrared wireless audio products are restricted to line-of-sight applications, i.e. only operate within a single room since the signal is broadcast as infrared light which can't go through walls. This technology is often found in wireless speaker kit products.
Infrared products send the audio as lightwaves. Light can't penetrate walls. For that reason devices utilizing infrared, such as wireless surround sound kits, are restricted to a single room. RF wireless audio devices broadcast the audio signal via radio waves. These radio wave signals can without problems go through walls. The signal is sent either by using FM transmission or digital transmission. The least expensive choice is FM transmission. Products utilizing FM transmission, on the other hand, have a number of drawbacks. These include degradation of the audio quality due to static or hiss and audio distortion. In addition, FM transmitter products are also quite prone to interference from other wireless transmitters.
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 using 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.

Also, some products require to buy separate wireless LAN modules that are plugged into every audio receiver.
Powerline products send the audio via the power mains and offer large range. They run into trouble in homes where there are individual mains circuits in terms of being able to cross over into another circuit. Also, these products build in a delay of a number of seconds to safeguard against transmission errors during power surges and spikes which prevents their use in applications where the audio from wireless loudspeakers has to be in sync with other non-wireless speakers or video.
Select a transmitter that has all of the audio inputs you need, e.g. speaker inputs, RCA inputs etc. Choose a system where you can add receivers later on which provide all of the required outputs, e.g. amplified speaker outputs, RCA outputs etc. Given that 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 have 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. Select 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. Products which work in the 5.8 GHz frequency band will have less trouble with wireless interference than products using the crowded 900 MHz or 2.4 GHz frequency band.
