A Number Of Suggestions To Help Select A Wireless Surround Sound Set
If your residence is not wired for audio then you face quite a challenge when you want to get your music from your living room to your bedroom. Often the audio source cannot be moved. Running speaker wires between rooms will be expensive and consequently many people are searching for other options. There are several technologies solving this problem. These include infrared wireless, RF wireless, wireless LAN (WLAN) and powerline.
Infrared is restricted to line of sight because the audio signal is broadcast as lightwaves and therefore devices utilizing this technology, such as infrared wireless surround sound products, are restricted to a single room.
RF wireless products will broadcast the signal as RF waves. These waves can easily go through walls. RF wireless audio products either make use of FM transmission or digital audio transmission. FM transmission is cheap but rather prone to hiss, audio distortion and susceptible to interference. Products which employ digital wireless audio transmission employ 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 completely preserved. Some transmitters utilize 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 attain the highest fidelity.
Products using digital wireless audio transmission, such as Amphony audio transmitter products, utilize a digital protocol in which the audio is converted to a digital signal prior to transmission. This method ensures that the audio quality is completely maintained. Some transmitters utilize some sort of audio compression, such as Bluetooth transmitters, which will degrade the audio to some extent. Transmitters which send the audio data uncompressed will attain the maximum fidelity.
Products utilizing wireless LAN are practical when streaming audio from a PC. Their downside is that they normally have some fairly high latency, i.e. the signal will be delayed by some amount since wireless LAN was not specifically designed for real-time audio streaming. WLAN receivers frequently do not have built-in network access. As a result, such products often require buying separate LAN cards. These cards are then plugged into every receiver.
Powerline products broadcast the audio by means of the power mains and provide large 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 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.
Select a transmitter that has all the audio inputs you need, such as speaker inputs, line-level RCA 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. If you go with a digital audio transmitter, choose one with an input audio level control knob to prevent the audio 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 desired Ohm rating. Selecting a product where the wireless receivers have a small footprint and easy mounting options will help during the installation. Devices using the less crowded 5.8 GHz frequency band will commonly have less problems with wireless interference than 900 MHz or 2.4 GHz devices.
