Various Helpful Hints To Help Pick A Cordless Surround Sound Package
The newest series of wireless surround sound transmitter devices promises streaming of music throughout the home without limits. We will take a look at the most widespread technologies for wireless audio and give some suggestions for picking the best wireless audio product.
Running music in your home can be a daunting job. 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 problem. Devices which solve this challenge are usually based on the following technologies: infrared wireless, RF wireless, wireless LAN or powerline.
RF wireless products will broadcast the signal as RF waves. These waves can easily go through walls. RF wireless audio devices either use FM transmission or digital audio transmission. FM transmission is economical but quite prone to hiss, audio distortion and susceptible to interference. Digital wireless audio transmitter devices, such as products from Amphony, utilize a digital protocol. The audio is first converted to digital data before being broadcast. This conversion and transmission in the digital domain will make sure that the original audio quality is preserved. However, this is only the case of the data is sent uncompressed. Some wireless audio transmitters will apply some sort of audio compression. Such products include Bluetooth audio transmitters. Audio compression will degrade the quality of the audio to some degree.
Digital wireless audio transmitter products, such as products from Amphony, make use of a digital protocol. The audio is first converted to digital data before being broadcast. Some wireless audio transmitters will employ audio compression, such as Bluetooth transmitters which will decrease the audio quality to some degree. Digital wireless audio transmitters which send the audio uncompressed provide the highest audio fidelity.
WLAN products are useful for broadcasting audio from a PC. However, wireless LAN was never designed for real-time audio streaming. As a consequence, products utilizing 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 every audio receiver.
Powerline products send the audio by means of the power mains and provide great range. They run into problems in homes where there are individual mains circuits in terms of being able to cross over into another circuit. Powerline products have another problem in the form of power surges and spikes which can cause transmission errors. To prevent audio dropouts, these products will usually have an audio latency of several seconds as a safeguard. Now we'll give you some recommendations for shopping for a wireless system: Choose 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. Some devices 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 ensure that the audio quality is preserved. Make sure the audio delay is less than 10 ms if you have a real-time application such as video.
Here are some recommendations for selecting the optimum 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 buy extra transmitters when you start adding receivers in different rooms of your house. Products with some type of error correction will be more resistant against radio interference from other wireless transmitters. Pick a digital RF audio transmitter to ensure that the audio quality is maintained. Make sure the audio latency is smaller than 10 ms if you have a real-time application such as video.
Make sure the wireless transmitter offers the audio inputs you require. You may need amplified speaker inputs, RCA audio inputs etc. Get a wireless system where you can purchase additional receivers later on. You should verify that you can get receivers for all the different applications you have. Such receivers may include amplified receivers for passive speakers or line-level receivers for active speakers. 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 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 used. Check that the system offers 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 provides low audio distortion. This is crucial for good sound quality. Check that the amplified receiver can drive speakers with the desired Ohm rating and that it is small and easily mountable for simple set up. Devices which operate in the 5.8 GHz frequency band will have less trouble with wireless interference than products using the crowded 900 MHz or 2.4 GHz frequency band.
