Several Secrets To Help Select A Wireless Surround Sound System
A Number Of Guidelines To Help Decide On A Cordless Surround Sound Product
The newest range of wireless surround sound transmitter devices promises streaming of music throughout the home without limits. We will check if these latest devices are suitable for whole-house audio. Also, we will give vital suggestions for choosing a wireless music system.
Infrared products send the audio as lightwaves. Light cannot penetrate walls. As a result products utilizing 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 problems go through walls. The signal is broadcast either by using FM transmission or digital transmission. FM transmission is inexpensive but rather prone to noise, 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 method ensures that the audio quality is entirely maintained. Some transmitters use some form of audio compression, such as Bluetooth transmitters, which will degrade the audio to some degree. Transmitters which send the audio data uncompressed will achieve the maximum fidelity.
Products which utilize digital wireless audio transmission utilize a digital protocol. Such products include transmitters from Amphony. In this protocol, before transmission the audio signal is converted to digital data. Some wireless audio transmitters will use audio compression, such as Bluetooth transmitters which will lower the audio quality to some degree. Digital wireless audio transmitters which send the audio uncompressed offer the highest audio fidelity.
Products using wireless LAN are useful when streaming audio from a PC. Their drawback is that they generally 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 frequently do not have built-in network access. As a result, such devices frequently require buying separate LAN cards. These cards are then plugged into every receiver.
Powerline products broadcast the audio via the power mains and provide great range. They run into trouble in homes where there are separate mains circuits in terms of being able to cross over into another circuit. Powerline products have another challenge in the form of power surges and spikes which can cause transmission errors. To avoid 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 buy a separate transmitter for every receiver. Products with some form of error correction will be more resistant against radio interference from other wireless transmitters. Choose a digital RF transmitter to preserve the original audio quality, ideally one with an audio latency of less than 10 ms in case of video or other time-sensitive applications.
For high amplifier power efficiency and greatest 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. Picking a product where the wireless receivers have a small footprint and easy mounting options will help during the installation. 5.8 GHz wireless devices normally have less trouble with interference from other wireless transmitters than devices working at 900 MHz or 2.4 GHz.
