Various Good Tips To Help Select A Wireless Surround Sound System
Recently more and more wireless surround sound transmitter devices have appeared which promise to deliver the ultimate freedom of broadcasting music throughout the house. We will look at the most widespread technologies for wireless audio and give some suggestions for picking the best wireless audio product.
Getting audio from your living room to your bed room can be quite a problem especially in buildings which are not wired for audio. Products which resolve this difficulty are mostly based on the following technologies: infrared wireless, RF wireless, wireless LAN or powerline.
Infrared wireless audio products are restricted to line-of-sight applications, i.e. only work within a single room since 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 will send the signal as RF waves. These waves can without problems go through walls. RF wireless audio products either make use of FM transmission or digital audio transmission. FM transmitters are the least expensive alternative. They provide good range but the music signal is prone to audio distortion and static and is extremely susceptible to interference from other wireless transmitters.
Products utilizing digital wireless audio transmission, such as Amphony audio transmitter products, use a digital protocol in which the audio is converted to a digital signal before transmission. Some wireless audio transmitters will employ audio compression, such as Bluetooth transmitters which will decrease the audio quality to some degree. Digital wireless audio transmitters which send the audio uncompressed provide the highest audio fidelity.
WLAN products are useful 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 typically require buying a separate LAN card to be plugged into every receiver.
Powerline devices use the power mains as a medium to send the audio. These products typically offer excellent range. On the other hand, they face problems if there are a number of separate mains circuits in the house. In this situation the signal will have problems crossing between these circuits. 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 speakers has to be in sync with other non-wireless speakers or video. Here are some tips for choosing 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. Products with some sort of error correction will be more immune against radio interference from other wireless transmitters. Pick a digital RF transmitter to preserve the original audio quality, preferably one with an audio latency of less than 10 ms in case of video or other time-sensitive applications.
Here are some recommendations for selecting a wireless audio system: If you plan to stream audio into numerous rooms of your house, be certain to select a system that permits streaming to multiple receivers at the same time. That way you don't have to purchase a separate transmitter for every 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. Select a digital RF audio transmitter to make sure 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.
Choose a transmitter that has all of the audio inputs you require, e.g. speaker inputs, RCA inputs etc. Pick a system where you can add receivers later on which offer all of the required outputs, e.g. amplified speaker outputs, RCA outputs etc. If you go with a digital audio transmitter, pick one with an input audio level control knob to prevent the audio signal from clipping inside the transmitter audio converter. This will guarantee optimum dynamic range regardless of the signal level of your equipment. Ensure 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. Choose a system which 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 set up. Products 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.
