Several Tricks To Help Decide On A Wireless Surround Sound Package A growing number of wireless surround sound transmitter products promise the ultimate freedom in streaming audio all over the home. We will investigate if these latest products are suitable for whole-house audio. Also, we will give important guidelines for selecting a wireless audio system.
The newest series of wireless surround sound transmitter devices promises streaming of music throughout the house without limits. We will take a look at the most widespread technologies for wireless audio and give some tips for choosing the best wireless audio product.
Running audio in your house can be a intimidating undertaking. A lot of houses are not wired for multi-room audio and getting the music from your living room to your bed room can be quite a challenge. Products which solve this challenge are mostly based on the following technologies: infrared wireless, RF wireless, wireless LAN or powerline.
RF wireless products broadcast the audio as RF waves - either by utilizing FM transmission or digital transmission - and can therefore without difficulty transmit through walls. The least expensive option is FM transmission. Products utilizing FM transmission, on the other hand, have a series of drawbacks. These include degradation of the audio quality due to noise or hiss and audio distortion. In addition, FM transmitter products are also quite susceptible to interference from other wireless transmitters.
Products utilizing 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 conversion and transmission in the digital domain will make sure that the original audio quality is preserved. On the other hand, this is only the case of the data is sent uncompressed. Some wireless audio transmitters will apply some form of audio compression. Such products include Bluetooth audio transmitters. Audio compression will degrade the quality of the audio to some extent.
Powerline products send the audio by means of the power mains and offer large range. They run into trouble in houses where there are individual mains circuits in terms of being able to cross over into another circuit. Also, these products build in a delay of a number of 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 suggestions for shopping for a wireless system: Pick 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 purchase a separate transmitter for every receiver. Choosing 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 audio transmitter to ensure that the audio quality is preserved. Make sure the audio latency is less than 10 ms if you have a real-time application such as video.

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. 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. Choose a system where you can add receivers later on which offer all of the necessary outputs, e.g. amplified speaker outputs, RCA outputs etc. If you go with a digital audio transmitter, select one with an input audio level control knob to prevent the audio signal from clipping inside the transmitter audio converter. This will ensure optimum dynamic range regardless of the signal level of your equipment. 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. Selecting a product where the wireless receivers have a small footprint and easy mounting options will help during the installation. 5.8 GHz wireless devices typically have less problems with interference from other wireless transmitters than products working at 900 MHz or 2.4 GHz.
