Some Recommendations To Help Select A Cordless Surround Sound System The newest range of wireless surround sound transmitter devices promises streaming of music throughout the home without limits. We will look at the most widespread technologies for wireless audio and give some tips for selecting the best wireless audio product.
A growing number of wireless surround sound transmitter devices claim the ultimate freedom in streaming audio all over the house. We will take a look at the most popular technologies for wireless audio and give some guidelines for choosing the best wireless audio product. Running audio in your home can be a daunting chore. Numerous houses 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 used by devices solving this problem: infrared, RF, wireless LAN and powerline.
Infrared is limited to line of sight since the audio signal is broadcast as lightwaves and for that reason devices using this technology, such as infrared wireless surround sound products, are limited to a single room.
RF wireless audio products 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. The least expensive option is FM transmission. Products utilizing FM transmission, on the other hand, 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 fairly prone to interference from other wireless transmitters.
Products using wireless LAN are useful when streaming audio from a PC. Their drawback is that they typically have some fairly high latency, i.e. the signal will be delayed by some amount since wireless LAN was not specifically designed for real-time audio streaming. WLAN receivers ordinarily require purchasing a separate LAN card to be plugged into each receiver.
Wireless LAN (WLAN) products are useful when streaming from a PC but will add some amount of latency or delay to the signal since wireless LAN was not originally designed for real-time audio streaming. WLAN receivers frequently do not have built-in network access. As a result, such products frequently require buying separate LAN cards. These cards are then plugged into each receiver.
Here are some suggestions for picking a wireless audio system: If you plan to stream audio into numerous rooms of your house, be sure to pick a system that allows streaming to several receivers at the same time. That way you don't have to purchase a separate transmitter for each receiver that you are streaming to. Products with some sort of error correction will be more resistant against radio interference from other wireless transmitters. Select a digital RF audio transmitter to guarantee that the audio quality is maintained. Make sure the audio latency 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. Pick a system where you can add receivers later on which offer all of the necessary 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 audio signal from clipping inside the transmitter audio converter. This will ensure 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. Verify that the amplified receiver is able to drive speakers with the desired Ohm rating and that it is small and easily mountable for easy installation. Products utilizing the less crowded 5.8 GHz frequency band will typically have less problems with wireless interference than 900 MHz or 2.4 GHz devices.
