Various Suggestions To Help Choose A Cordless Surround Sound Set The newest range of wireless surround sound transmitter devices claims streaming of music throughout the home without limits. We will check if these latest products are suitable for whole-house audio. Also, we will give vital guidelines for selecting a wireless audio system.

The newest series of wireless surround sound transmitter devices claims streaming of music throughout the house without limits. We will examine if these newest devices are suitable for whole-house audio. Also, we will give crucial guidelines for selecting a wireless music system.

Infrared wireless audio devices are limited to line-of-sight applications, i.e. only function within a single room since the signal is broadcast as infrared light which can't penetrate walls. This technology is often found in wireless speaker kit products.

RF wireless products send the music as RF waves - either by using FM transmission or digital transmission - and can as a result without problems transmit through walls. FM transmission is economical but quite prone to static, audio distortion and susceptible to interference. Digital wireless audio transmitter products, such as products from Amphony, utilize a digital protocol. The audio is first converted to digital data before being broadcast. Some wireless audio transmitters will utilize audio compression, such as Bluetooth transmitters which will reduce the audio quality to some degree. Digital wireless audio transmitters which broadcast the audio uncompressed provide the highest audio fidelity.

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 prior to transmission. This method guarantees that the audio quality is completely preserved. Some transmitters employ some type of audio compression, such as Bluetooth transmitters, which will degrade the audio to some degree. Transmitters which broadcast the audio data uncompressed will attain the maximum fidelity.

WLAN products are convenient 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. WLAN receivers usually require purchasing a separate LAN card to be plugged into each receiver.

Powerline devices employ the power mains to distribute audio and offer large range but run into trouble if there are separate mains circuits in the house in terms of crossing between circuits. Powerline products have another problem in the form of power surges and spikes which can cause transmission errors. To avoid audio dropouts, these products will commonly have an audio latency of several seconds as a safeguard. Here are some recommendations 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 start adding receivers in different rooms of your home. Some devices have some form of error correction built in which will help guard against dropouts in case of strong wireless interference. 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 less than 10 ms would be appropriate for most scenarios.

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. Given that you may want to connect the transmitter to several sources, you should choose 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 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 crucial for good sound quality. Check that the amplified receiver is able to drive speakers with the desired Ohm rating and that it is small and easily mountable for easy installation. Devices utilizing the less crowded 5.8 GHz frequency band will typically have less trouble with wireless interference than 900 MHz or 2.4 GHz products.
