A Number Of Suggestions To Help Select A Cordless Surround Sound Set
Some Secrets To Help Choose A Wireless Surround Sound System
Lately more and more wireless surround sound transmitter products have emerged which promise to bring the ultimate freedom of sending music throughout the home. We will take a look at various products and technologies to find out in how far these products are useful for whole-house audio uses and what to look out for when buying a wireless system.
Infrared is limited to line of sight because the audio signal is broadcast as lightwaves and as a result devices using this technology, such as infrared wireless surround sound products, are restricted to a single room.
RF wireless audio devices send the audio signal via radio waves. These radio wave signals can easily go through walls. The signal is broadcast either by utilizing FM transmission or digital transmission. FM transmission is economical but rather prone to hiss, audio distortion and susceptible to interference. Products using digital wireless audio transmission, such as Amphony audio transmitter products, employ a digital protocol in which the audio is converted to a digital signal before transmission. This method guarantees that the audio quality is completely preserved. Some transmitters utilize some type 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 highest fidelity.
Products which use digital wireless audio transmission employ a digital protocol. Such devices include transmitters from Amphony. In this protocol, before transmission the audio signal is converted to digital data. This conversion and transmission in the digital domain will make sure that the original audio quality is maintained. 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 extent.
Powerline products utilize the power mains as a medium to send the audio. These products usually provide excellent range. However, they face trouble if there are a number of separate mains circuits in the home. In this case the signal will have problems crossing between these circuits. Also, these products build in a delay of several seconds to safeguard against transmission errors during power surges and spikes which prevents their use in applications where the audio from wireless speakers has to be in sync with other non-wireless speakers or video.
Now we'll give you some tips for shopping for a wireless system: Select a system that supports numerous 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 products have some sort of error correction built in which will help guard against dropouts in case of strong wireless interference. Select a digital RF transmitter to maintain the original audio quality, ideally one with an audio latency of less than 10 ms in case of video or other time-sensitive applications.
Now we'll give you some tips for shopping for a wireless system: Choose a system that supports numerous 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 every receiver. Picking a product with some form of error correction will help mitigate against strong RF interference. Such interference can be brought on by 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.
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, select 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. Make sure 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. Choose a system that offers 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. 5.8 GHz wireless products typically have less problems with interference from other wireless transmitters than devices operating at 900 MHz or 2.4 GHz.
