A Number Of Tips To Help Choose A Wireless Surround Sound Package
The newest series of wireless surround sound transmitter products claims streaming of music throughout the home without limits. We will check if these latest products are suitable for whole-house audio. Also, we will give crucial tips for selecting a wireless audio system. If your residence is not wired for audio then you face quite a problem when you want to get your music from your living room to your bed room. Often the audio source cannot be moved. Running speaker wires between rooms will be costly and for that reason a lot of people are searching for alternatives. There are a number of technologies solving this problem. These include infrared wireless, RF wireless, wireless LAN (WLAN) and powerline.
Infrared is restricted to line of sight because the audio signal is sent as lightwaves and as a result products utilizing this technology, such as infrared wireless surround sound products, are restricted to a single room.
RF wireless music products broadcast the music 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 option is FM transmission. Products using FM transmission, however, have a series of drawbacks. These include degradation of the audio quality due to noise or hiss and audio distortion. In addition, FM transmitter products are also fairly prone to interference from other wireless transmitters. Products which use digital wireless audio transmission employ a digital protocol. Such products include transmitters from Amphony. In this protocol, before transmission the audio signal is converted to digital data. This method guarantees that the audio quality is completely preserved. Some transmitters utilize some type of audio compression, such as Bluetooth transmitters, which will degrade the audio to some degree. Transmitters which broadcast the audio data uncompressed will achieve the highest fidelity.
Digital wireless audio transmitter devices, such as products from Amphony, utilize a digital protocol. The audio is first converted to digital data before being transmitted. This conversion and transmission in the digital domain will make sure that the original audio quality is maintained. However, this is only the case of the data is sent uncompressed. Some wireless audio transmitters will apply some sort of audio compression. Such products include Bluetooth audio transmitters. Audio compression will degrade the quality of the audio to some extent.
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. WLAN receivers usually require buying a separate LAN card to be plugged into every receiver.
Powerline products use the power mains as a medium to send the music. These products usually provide excellent range. On the other hand, they face problems if there are a number of separate mains circuits in the house. In this case the signal will have difficulty crossing between these circuits. Another problem confronting 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 generally build a delay of several seconds into the transmission. Here are some suggestions for choosing 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 purchase extra transmitters when you start adding receivers in several rooms of your house. Selecting a product with some sort of error correction will help mitigate against strong RF interference. Such interference can be caused by other wireless transmitters. Choose a digital RF audio transmitter to make sure that the audio quality is maintained. Make sure the audio latency is smaller than 10 ms if you have a real-time application such as video.
Pick a transmitter that has all the audio inputs you need, such as speaker inputs, line-level RCA inputs etc. Get a wireless system where you can purchase additional receivers later on. You should confirm that you can get receivers for all the different applications you have. Such receivers may include amplified receivers for passive speakers or line-level receivers for active speakers. If you go with a digital audio transmitter, choose one with an input audio level control knob to prevent the music signal from clipping inside the transmitter audio converter. This will guarantee optimum dynamic range regardless of the signal level of your equipment.
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 provide optimum sound quality. Choose a system that 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 installation. Products using the less crowded 5.8 GHz frequency band will commonly have less problems with wireless interference than 900 MHz or 2.4 GHz products.
