Several Helpful Hints To Help Select A Wireless Surround Sound Kit Recently more and more wireless surround sound transmitter products have emerged which claim to deliver the ultimate freedom of sending music throughout the house. We will investigate if these latest devices are suitable for whole-house audio. Also, we will give vital guidelines for selecting a wireless music system.
Recently more and more wireless surround sound transmitter devices have appeared which promise to bring the ultimate freedom of sending music throughout the house. We will take a look at the most widespread technologies for wireless audio and give some recommendations for picking the best wireless audio product. Getting audio from your living room to your bed room can be quite a challenge in particular in homes which are not wired for audio. There are a number of technologies solving this problem. These include infrared wireless, RF wireless, wireless LAN (WLAN) and powerline.
If your house 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. Frequently the audio source cannot be moved. Running speaker wires between rooms will be costly and consequently a lot of people are looking for alternatives. Products which solve this problem are mostly based on the following technologies: infrared wireless, RF wireless, wireless LAN or powerline.
Infrared products send the audio as lightwaves. Light can't penetrate walls. As a result devices utilizing infrared, such as wireless surround sound kits, are limited to a single room. RF wireless products will send the signal as RF waves. These waves can without difficulty go through walls. RF wireless audio devices either utilize FM transmission or digital audio transmission. The least expensive option is FM transmission. Products utilizing FM transmission, however, 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 rather susceptible to interference from other wireless transmitters.
Wireless LAN (WLAN) products are practical 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 buy separate wireless LAN modules that are plugged into every audio receiver.
Wireless LAN (WLAN) products are practical 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 products often require buying separate LAN cards. These cards are then plugged into every receiver.
Powerline products utilize the power mains to distribute audio and offer large range but run into problems if there are individual mains circuits in the home 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 generally have an audio latency of several seconds as a safeguard.
Select a transmitter that has all the audio inputs you require, such as speaker inputs, line-level RCA inputs etc. Select a system where you can add receivers later on which provide all of the required outputs, e.g. amplified speaker outputs, RCA outputs etc. Select a transmitter that can adjust 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.
For high amplifier power efficiency and best sound quality, confirm that the amplified receiver has a built-in low-distortion digital amplifier. Choose a system that provides 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. Products which work in the 5.8 GHz frequency band will have less trouble with wireless interference than products utilizing the crowded 900 MHz or 2.4 GHz frequency band.
