Various Tips To Help Choose A Wireless Surround Sound Package
Recently more and more wireless surround sound transmitter devices have appeared which promise to bring the ultimate freedom of sending music throughout the house. We will check if these latest products are suitable for whole-house audio. Also, we will give important tips for selecting a wireless audio system. Getting audio from your living room to your bed room can be quite a challenge especially in homes which are not wired for audio. The following technologies are used by devices solving this problem: infrared, RF, wireless LAN and powerline.
Getting audio from your living room to your bedroom can be quite a problem in particular in houses which are not wired for audio. The following technologies are used by devices solving this problem: infrared, RF, wireless LAN and powerline.
RF wireless audio products send the audio signal via radio waves. These radio wave signals can without difficulty go through walls. The signal is sent either by using FM transmission or digital transmission. FM transmission is economical but rather prone to hiss, audio distortion and susceptible to interference. 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. This method guarantees that the audio quality is entirely preserved. Some transmitters utilize 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 highest 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 using WLAN will introduce some amount of delay to the signal. Also, some products require to buy separate wireless LAN modules that are plugged into each audio receiver.
Products using wireless LAN are useful when streaming audio from a PC. Their disadvantage is that they typically have some fairly high latency, i.e. the signal will be delayed by some amount since wireless LAN was not particularly designed for real-time audio streaming. WLAN receivers typically require buying a separate LAN card to be plugged into every receiver.
Here are some tips for picking 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 begin adding receivers in several rooms of your house. Some devices have some type of error correction built in which will help guard against dropouts in case of strong wireless interference. Select a digital RF audio transmitter to ensure that the audio quality is preserved. Make sure the audio latency is smaller 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. Make sure that you can purchase individual receivers later on as you expand your system. Verify 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 music signal from clipping inside the transmitter audio converter. This will guarantee optimum dynamic range regardless of the signal level of your equipment.
For high amplifier power efficiency and greatest sound quality, check that the amplified receiver has a built-in low-distortion digital amplifier. Make sure the receivers can drive speakers with your preferred Ohm rating. Selecting a product where the wireless receivers have a small footprint and easy mounting options will help in the course of the installation. 5.8 GHz wireless products typically have less trouble with interference from other wireless transmitters than devices working at 900 MHz or 2.4 GHz.
