Various Guidelines To Help Pick A Wireless Surround Sound Product
Running audio in your house can be a daunting job. A lot of homes are not wired for multi-room audio and getting the music from your living room to your bed room can be quite a problem. The following technologies are used by products solving this problem: infrared, RF, wireless LAN and powerline.
Infrared wireless audio devices are restricted to line-of-sight applications, i.e. only work within a single room since the signal is sent as infrared light which cannot penetrate walls. This technology is frequently found in wireless speaker kit products.
Infrared is limited to line of sight since the audio signal is sent as lightwaves and therefore products using this technology, such as infrared wireless surround sound products, are limited to a single room. RF wireless products will broadcast the signal as RF waves. These waves can without difficulty go through walls. RF wireless audio devices either make use of FM transmission or digital audio transmission. The least expensive choice is FM transmission. Products utilizing FM transmission, however, have a number of drawbacks. These include degradation of the audio quality due to noise or hiss and audio distortion. In addition, FM transmitter products are also rather prone to interference from other wireless transmitters.
Digital wireless audio transmitter products, such as products from Amphony, make use of a digital protocol. The audio is first converted to digital data before being transmitted. This conversion and transmission in the digital domain will guarantee 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 type of audio compression. Such products include Bluetooth audio transmitters. Audio compression will degrade the quality of the audio to some degree.
Powerline devices utilize the power mains as a medium to send the audio. These products usually provide excellent range. However, they face trouble if there are several separate mains circuits in the home. In this case the signal will have problems crossing between these circuits. 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 commonly have an audio latency of several seconds as a safeguard.
Powerline products use the power mains to distribute audio and provide great range but run into trouble if there are separate mains circuits in the house in terms of crossing between circuits. Powerline products have another challenge in the form of power surges and spikes which can cause transmission errors. To avoid audio dropouts, these products will commonly have an audio latency of several seconds as a safeguard. Here are some tips for selecting a wireless audio system: If you plan to stream audio into several rooms of your house, be sure to select a system that permits streaming to multiple receivers at the same time. That way you don't have to buy a separate transmitter for every receiver that you are streaming to. Products with some type of error correction will be more resistant against radio interference from other wireless transmitters. Pick a digital RF audio transmitter to guarantee that the audio quality is maintained. Make sure the audio delay 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 need, e.g. speaker inputs, RCA inputs etc. Select a system where you can add receivers later on which provide all of the necessary outputs, e.g. amplified speaker outputs, RCA outputs etc. Because you may want to connect the transmitter to several sources, you should choose a transmitter that can be adjusted to different signal volume levels to prevent clipping of the audio signal inside the transmitter converter stage.
For high amplifier power efficiency and best sound quality, confirm that the amplified receiver has a built-in low-distortion digital amplifier. Select a system which offers 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. Devices which operate in the 5.8 GHz frequency band will have less problems with wireless interference than products utilizing the crowded 900 MHz or 2.4 GHz frequency band.
