Various Secrets To Help Choose A Cordless Surround Sound Set The latest series of wireless surround sound transmitter products promises streaming of music throughout the house without limits. We will take a look at the most common technologies for wireless audio and give some guidelines for picking the best wireless audio product.
Running audio in your home can be a intimidating undertaking. Numerous 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 several technologies solving this problem. These include infrared wireless, RF wireless, wireless LAN (WLAN) and powerline.
Infrared products broadcast the audio as lightwaves. Light can't go through walls. For that reason products utilizing infrared, such as wireless surround sound kits, are limited to a single room.
Infrared products send the audio as lightwaves. Light can't go through walls. For that reason devices using infrared, such as wireless surround sound kits, are restricted to a single room. RF wireless music devices broadcast the audio signal via radio waves. These radio wave signals can without difficulty go through walls. The signal is broadcast either by using FM transmission or digital transmission. FM transmission is inexpensive but rather prone to static, audio distortion and susceptible to interference.
Products using digital wireless audio transmission, such as Amphony audio transmitter products, make use of a digital protocol in which the audio is converted to a digital signal prior to transmission. Some wireless audio transmitters will utilize audio compression, such as Bluetooth transmitters which will reduce the audio quality to some extent. Digital wireless audio transmitters which broadcast the audio uncompressed provide the highest audio fidelity.
Powerline devices utilize the power mains to distribute music and provide great range but run into trouble if there are individual mains circuits in the home in terms of crossing between circuits. Another challenge facing 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 generally build a delay of several seconds into the transmission.
Here are some hints for picking a wireless audio system: If you plan to stream audio into several rooms of your house, be certain to go for a system that allows 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 devices have some sort of error correction built in which will help guard against dropouts in case of strong wireless interference. Digital RF audio transmitters will be able to preserve the original audio quality. If you have time-critical applications where sync of the audio is important then you should get a transmitter with a low audio latency. An audio latency of smaller than 10 ms would be suitable for most scenarios.
Make sure the wireless transmitter offers the audio inputs you need. You may need amplified speaker inputs, RCA audio inputs etc. Make sure that you can purchase additional 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. 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.
For high amplifier power efficiency and best sound quality, check that the amplified receiver has a built-in low-distortion digital amplifier. Select a system which provides 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. Devices 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.
