Several Tips To Help Decide On A Wireless Surround Sound Package Lately more and more wireless surround sound transmitter products have appeared which claim to bring the ultimate freedom of broadcasting music throughout the house. We will look at different products and technologies to find out in how far these products are practical for whole-house audio uses and what to look out for when purchasing a wireless system.
The newest range of wireless surround sound transmitter devices promises streaming of music throughout the home without limits. We will take a look at the most common technologies for wireless audio and give some suggestions for picking the best wireless audio product. Getting audio from your living room to your bedroom can be quite a challenge especially in buildings which are not wired for audio. There are several technologies solving this problem. These include infrared wireless, RF wireless, wireless LAN (WLAN) and powerline.
Running audio in your home can be a intimidating undertaking. 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.
RF wireless products will send the signal as RF waves. These waves can easily go through walls. RF wireless audio products either use FM transmission or digital audio transmission. FM transmission is inexpensive but rather prone to noise, audio distortion and susceptible to interference. Products which use digital wireless audio transmission utilize a digital protocol. Such devices include transmitters from Amphony. In this protocol, prior to transmission the audio signal is converted to digital data. Some wireless audio transmitters will utilize audio compression, such as Bluetooth transmitters which will lower the audio quality to some extent. Digital wireless audio transmitters which send the audio uncompressed provide the highest audio fidelity.
Digital wireless audio transmitter products, such as products from Amphony, utilize a digital protocol. The audio is first converted to digital data before being broadcast. This method guarantees that the audio quality is entirely preserved. Some transmitters employ some type of audio compression, such as Bluetooth transmitters, which will degrade the audio to some degree. Transmitters which broadcast the audio data uncompressed will attain the maximum fidelity.
WLAN products are practical for broadcasting audio from a PC. However, wireless LAN was never designed for real-time audio streaming. As a result, products utilizing WLAN will introduce some amount of delay to the signal. Also, a number of products require to purchase separate wireless LAN modules that are plugged into each audio receiver.
Now we'll give you some pointers for shopping for a wireless system: Go for a system that supports numerous wireless receivers if you plan to stream audio to several rooms so that you don't have to purchase a separate transmitter for every receiver. Selecting a product with some type of error correction will help mitigate against strong RF interference. Such interference can be brought on by other wireless transmitters. 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 less than 10 ms would be suitable for most scenarios.
Choose a transmitter that has all the audio inputs you require, such as speaker inputs, line-level RCA inputs etc. Choose a system where you can add receivers later on which offer all of the required outputs, e.g. amplified speaker outputs, RCA outputs etc. Pick a transmitter that can adjust the audio volume of the input stage. This will give you the versatility to connect the transmitter to any kind of equipment with different signal levels. Otherwise the audio may get clipped inside the transmitter converter stage or the dynamic range is not fully utilized.
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 separate receivers later on as you expand your system. Check 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 avoid the audio signal from clipping inside the transmitter audio converter. This will guarantee optimum dynamic range regardless of the signal level of your equipment. Verify that the amplified wireless receivers have built-in digital amplifiers with low distortion figures. This will keep the receiver cool due to high amplifier power efficiency and offer maximum sound quality. Pick a system which provides 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 work in the 5.8 GHz frequency band will have less problems with wireless interference than devices utilizing the crowded 900 MHz or 2.4 GHz frequency band.
