Some Helpful Hints To Help Select A Wireless Surround Sound Product
Running music in your home can be a intimidating chore. Many homes are not wired for multi-room audio and getting the music from your living room to your bed room can be quite a challenge. There are a number of technologies solving this problem. These include infrared wireless, RF wireless, wireless LAN (WLAN) and powerline.
Infrared is limited to line of sight because the audio signal is sent as lightwaves and consequently devices utilizing 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 problems go through walls. RF wireless audio devices either utilize FM transmission or digital audio transmission. FM transmission is cheap but quite prone to noise, audio distortion and susceptible to interference.
WLAN products are convenient 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. Also, a number of products require to buy separate wireless LAN modules that are plugged into each audio receiver.
Powerline products send the audio via the power mains and offer great range. They run into trouble in homes where there are individual 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 commonly build a delay of several seconds into the transmission.
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. Another challenge confronting powerline products are strong power surges and spikes. Such surges can bring about dropouts in the audio due to errors in the transmission. To safeguard against these errors, powerline products usually build a delay of several seconds into the transmission. Now we'll give you some recommendations for shopping for a wireless system: Select a system that supports numerous wireless receivers if you plan to stream audio to several rooms so that you don't have to buy a separate transmitter for every receiver. Some products have some sort of error correction built in which will help guard against dropouts in case of strong wireless interference. Pick a digital RF audio transmitter to guarantee that the audio quality is maintained. Make sure the audio delay is smaller than 10 ms if you have a real-time application such as video.
Select a transmitter that has all the audio inputs you need, such as speaker inputs, line-level 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 avoid the music signal from clipping inside the transmitter audio converter. This will guarantee optimum dynamic range regardless of the signal level of your equipment.
For high amplifier power efficiency and best sound quality, verify that the amplified receiver has a built-in low-distortion digital amplifier. Make sure the receivers can drive speakers with your desired Ohm rating. Choosing a product where the wireless receivers have a small footprint and easy mounting options will help during the installation. Products which function in the 5.8 GHz frequency band will have less trouble with wireless interference than devices utilizing the crowded 900 MHz or 2.4 GHz frequency band.
