Various Helpful Hints To Help Pick A Cordless Surround Sound Package The newest range of wireless surround sound transmitter products claims streaming of music throughout the home without limits. We will investigate if these newest devices are suitable for whole-house audio. Also, we will give vital suggestions for selecting a wireless music system.
Getting audio from your living room to your bed room can be quite a challenge in particular in houses which are not wired for audio. Devices which solve this problem are commonly based on the following technologies: infrared wireless, RF wireless, wireless LAN or powerline.
Getting audio from your living room to your bed room can be quite a problem particularly in buildings which are not wired for audio. The following technologies are used by devices solving this problem: infrared, RF, wireless LAN and powerline.
RF wireless products broadcast the music as RF waves - either by utilizing FM transmission or digital transmission - and can therefore without difficulty transmit through walls. 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, use 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 use some type of audio compression, such as Bluetooth transmitters, which will degrade the audio to some extent. Transmitters which broadcast the audio data uncompressed will achieve the maximum fidelity.
Wireless LAN (WLAN) products are useful when streaming from a PC but will add some amount of latency or delay to the signal because wireless LAN was not originally designed for real-time audio streaming. Also, a number of products require to purchase separate wireless LAN modules that are plugged into every audio receiver.
Powerline products broadcast the audio via the power mains and provide great range. They run into trouble in houses where there are separate mains circuits in terms of being able to cross over into another circuit. 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 loudspeakers has to be in sync with other non-wireless speakers or video.
Here are some guidelines for selecting the perfect 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 different rooms of your house. Products with some form of error correction will be more immune against radio interference from 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 crucial then you should get a transmitter with a low audio latency. An audio latency of smaller than 10 ms would be appropriate for most scenarios.
Choose a transmitter that has all the audio inputs you need, such as speaker inputs, line-level RCA inputs etc. Make sure that you can purchase separate 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. Since you may want to connect the transmitter to several sources, you should select a transmitter that can be adjusted to different signal volume levels to prevent clipping of the audio signal inside the transmitter converter stage.

Ensure 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, pick one with an input audio level control knob to prevent the music signal from clipping inside the transmitter audio converter. This will ensure optimum dynamic range regardless of the signal level of your equipment. Make sure that the system provides 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 vital for good sound quality. Select 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 installation. 5.8 GHz wireless devices typically have less trouble with interference from other wireless transmitters than devices operating at 900 MHz or 2.4 GHz.
