A Few Guidelines To Help Decide On A Wireless Surround Sound Set The newest range of wireless surround sound transmitter products claims streaming of music throughout the house without limits. We will take a look at the most popular technologies for wireless audio and give some guidelines for picking the best wireless audio product.
Running music in your home can be a intimidating chore. A lot of buildings are not wired for multi-room audio and getting the music from your living room to your bedroom can be quite a problem. The following technologies are utilized by products solving this problem: infrared, RF, wireless LAN and powerline.
Infrared products send the audio as lightwaves. Light cannot go through walls. Consequently devices utilizing infrared, such as wireless surround sound kits, are limited to a single room.
RF wireless products broadcast the audio as RF waves - either by using FM transmission or digital transmission - and can consequently easily transmit through walls. The least expensive option is FM transmission. Products using 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 quite susceptible to interference from other wireless transmitters.
Products utilizing digital wireless audio transmission, such as Amphony audio transmitter products, utilize a digital protocol in which the audio is converted to a digital signal before transmission. This method ensures that the audio quality is fully preserved. Some transmitters use some sort of audio compression, such as Bluetooth transmitters, which will degrade the audio to some degree. Transmitters which send the audio data uncompressed will achieve the highest fidelity.
WLAN products are useful for broadcasting audio from a PC. However, wireless LAN was never designed for real-time audio streaming. As a result, products using WLAN will introduce some amount of delay to the signal. WLAN receivers ordinarily require buying a separate LAN card to be plugged into every receiver.
Powerline products broadcast the audio by means of the power mains and provide large range. They run into problems in houses where there are separate mains circuits in terms of being able to cross over into another circuit. 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 typically build a delay of several seconds into the transmission. Now we'll give you some suggestions for shopping for a wireless system: Select a system that supports multiple wireless receivers if you plan to stream audio to a number of rooms so that you don't have to purchase a separate transmitter for each receiver. Choosing a product with some form of error correction will help mitigate against strong RF interference. Such interference can be brought on by other wireless transmitters. Select a digital RF audio transmitter to make sure that the audio quality is preserved. Make sure the audio latency is smaller than 10 ms if you have a real-time application such as video.
Here are some suggestions 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 house. Some products have some type of error correction built in which will help guard against dropouts in case of strong wireless interference. Pick a digital RF audio transmitter to ensure 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 require, e.g. speaker inputs, RCA inputs etc. Make sure that you can buy individual receivers later on as you expand your system. Verify that you can get receivers with speaker outputs for connecting regular loudspeakers as well as receivers with line-level RCA outputs. Select a transmitter that can regulate the audio volume of the input stage. This will give you the versatility to connect the transmitter to any type of equipment with different signal levels. Otherwise the audio may get clipped inside the transmitter converter stage or the dynamic range is not fully used. Make sure that the system provides amplified receivers with a digital amplifier to guarantee high power efficiency. This will help keep the receiver cool during operation. Also, make sure the amplifier offers low audio distortion. This is vital for good sound quality. Verify that the amplified receiver can drive speakers with the preferred Ohm rating and that it is small and easily mountable for easy installation. 5.8 GHz wireless devices usually have less problems with interference from other wireless transmitters than products operating at 900 MHz or 2.4 GHz.
