Several Helpful Hints To Help Pick A Wireless Surround Sound Kit The latest 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 advice for picking the best wireless audio product.
Lately more and more wireless surround sound transmitter products have emerged which promise to bring the ultimate freedom of broadcasting music throughout the home. We will look at the most common technologies for wireless audio and give some advice for picking the best wireless audio product.
If your house is not wired for audio then you face quite a problem when you want to get your music from your living room to your bed room. Often the audio source cannot be moved. Running speaker wires between rooms will be costly and as a result a lot of people are looking for alternatives. The following technologies are used by products solving this problem: infrared, RF, wireless LAN and powerline.
RF wireless products will send the signal as RF waves. These waves can easily penetrate walls. RF wireless audio devices either use FM transmission or digital audio transmission. FM transmitters are the cheapest option. They provide good range but the music signal is prone to audio distortion and hiss and is very 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. Some wireless audio transmitters will use audio compression, such as Bluetooth transmitters which will lower the audio quality to some extent. Digital wireless audio transmitters which broadcast the audio uncompressed provide the highest audio fidelity.
WLAN products are practical for broadcasting audio from a PC. However, wireless LAN was never designed for real-time audio streaming. As a result, products utilizing WLAN will introduce some amount of delay to the signal. WLAN receivers frequently do not have built-in network access. As a result, such devices often require purchasing separate LAN cards. These cards are then plugged into every receiver.
Powerline devices use the power mains as a medium to send the music. These products normally offer excellent range. However, they face trouble if there are several separate mains circuits in the house. In this situation the signal will have trouble crossing between these circuits. Another problem confronting powerline products are strong power surges and spikes. Such surges can bring about dropouts in the audio due to errors in the transmission. To safeguard against these errors, powerline products generally build a delay of several seconds into the transmission.
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 separate receivers later on. You should check 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 adjust the audio volume of the input stage. This will give you the versatility 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.
Ensure that the amplified wireless receivers have built-in digital amplifiers with low distortion figures. This will keep the receiver cool due to high amplifier power efficiency and provide optimum sound quality. Make sure the receivers can drive speakers with your desired Ohm rating. Picking a product where the wireless receivers have a small footprint and easy mounting options will help during the set up. Devices using the less crowded 5.8 GHz frequency band will commonly have less trouble with wireless interference than 900 MHz or 2.4 GHz devices.
