Various Suggestions To Help Pick A Cordless Surround Sound Set
Recently more and more wireless surround sound transmitter devices have emerged which promise to deliver the ultimate freedom of sending music throughout the home. We will have a look at different products and technologies to find out in how far these products are useful for whole-house audio applications and what to look out for when purchasing a wireless system.
Infrared is limited to line of sight because the audio signal is sent as lightwaves and as a result devices using this technology, such as infrared wireless surround sound products, are restricted to a single room.
RF wireless products broadcast the audio as RF waves - either by using FM transmission or digital transmission - and can for that reason without problems transmit through walls. FM transmitters are the least expensive option. They offer good range but the music signal is prone to audio distortion and noise and is extremely susceptible to interference from other wireless transmitters.
Products using wireless LAN are useful 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 particularly designed for real-time audio streaming. Also, a number of 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 drawback 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 frequently do not have built-in network access. As a result, such products frequently require purchasing separate LAN cards. These cards are then plugged into every receiver.
Powerline devices use the power mains as a medium to broadcast the audio. These products normally offer excellent range. On the other hand, they face problems if there are several separate mains circuits in the house. In this situation the signal will have difficulty crossing between these circuits. 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 tips for selecting 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 purchase extra transmitters when you start adding receivers in different rooms of your house. Products with some sort of error correction will be more resistant against radio interference from other wireless transmitters. Pick a digital RF audio transmitter to make sure that the audio quality is preserved. Make sure the audio delay is smaller than 10 ms if you have a real-time application such as video.
Pick a transmitter that has all of the audio inputs you require, e.g. speaker inputs, RCA inputs etc. Make sure that you can buy 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. Select a transmitter that can regulate the audio volume of the input stage. This will give you the flexibility to connect the transmitter to any kind of equipment with different signal levels. Otherwise the audio may get clipped inside the transmitter converter stage or the dynamic range is not fully used.
Check that the system offers amplified receivers with a digital amplifier to ensure high power efficiency. This will help keep the receiver cool during operation. In addition, make sure the amplifier provides low audio distortion. This is important for good sound quality. Make sure the receivers can drive speakers with your preferred Ohm rating. Picking a product where the wireless receivers have a small footprint and easy mounting options will help in the course of the installation. Products using the less crowded 5.8 GHz frequency band will generally have less trouble with wireless interference than 900 MHz or 2.4 GHz products.
