A Few Recommendations To Help Select A Cordless Surround Sound System The latest range of wireless surround sound transmitter devices claims streaming of music throughout the home without limits. We will take a look at different products and technologies to find out in how far these products are effective for whole-house audio applications and what to look out for when purchasing a wireless system.
Lately more and more wireless surround sound transmitter products have appeared which promise to bring the ultimate freedom of broadcasting music throughout the house. We will take a look at the most widespread technologies for wireless audio and give some suggestions for choosing the best wireless audio product. 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 resolve this difficulty are usually based on the following technologies: infrared wireless, RF wireless, wireless LAN or powerline.
Infrared wireless audio products are limited to line-of-sight applications, i.e. only function within a single room since the signal is sent as infrared light which can't penetrate walls. This technology is often found in wireless speaker kit products.
RF wireless audio products broadcast the audio signal via radio waves. These radio wave signals can without difficulty go through walls. The signal is sent either by utilizing FM transmission or digital transmission. The least expensive option is FM transmission. Products using FM transmission, on the other hand, have a series of drawbacks. These include degradation of the audio quality due to static or hiss and audio distortion. In addition, FM transmitter products are also quite prone to interference from other wireless transmitters. Products utilizing 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 guarantees that the audio quality is entirely maintained. Some transmitters employ some type of audio compression, such as Bluetooth transmitters, which will degrade the audio to some extent. Transmitters which send 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 since wireless LAN was not originally designed for real-time audio streaming. Also, some products require to purchase separate wireless LAN modules that are plugged into every audio receiver.
Wireless LAN (WLAN) products are useful when streaming from a PC but will add some amount of latency or delay to the signal since wireless LAN was not originally designed for real-time audio streaming. WLAN receivers frequently do not have built-in network access. As a result, such devices frequently require buying separate LAN cards. These cards are then plugged into each receiver.
Now we'll give you some guidelines for shopping for a wireless system: Select a system that supports multiple wireless receivers if you plan to stream audio to several rooms so that you don't have to buy a separate transmitter for each receiver. Some devices have some type of error correction built in which will help guard against dropouts in case of strong wireless interference. Pick a digital RF transmitter to maintain the original audio quality, ideally one with an audio latency of less than 10 ms in case of video or other time-sensitive applications.
Choose a transmitter that has all the audio inputs you require, such as speaker inputs, line-level 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. Choose a transmitter that can regulate the audio volume of the input stage. This will give you the versatility 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 utilized.
Make sure the wireless transmitter provides the audio inputs you require. You may need amplified speaker inputs, RCA audio inputs etc. Get a wireless system where you can buy separate receivers later on. You should confirm 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. Choose a transmitter that can regulate the audio volume of the input stage. This will give you the flexibility to connect the transmitter to any type 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 offers low audio distortion. This is crucial for good sound quality. Select a system which offers receivers that can drive speakers with the desired 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 products usually have less trouble with interference from other wireless transmitters than devices working at 900 MHz or 2.4 GHz.
