Various Recommendations To Help Pick A Wireless Surround Sound Product
Recently more and more wireless surround sound transmitter products have appeared which claim to bring the ultimate freedom of broadcasting music throughout the house. We will research if these newest devices are suitable for whole-house audio. Also, we will give crucial tips for selecting a wireless audio system. 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 expensive and therefore a lot of people are searching for other options. Devices which resolve this difficulty are commonly based on the following technologies: infrared wireless, RF wireless, wireless LAN or powerline.
Infrared is restricted to line of sight since the audio signal is sent as lightwaves and therefore products utilizing this technology, such as infrared wireless surround sound products, are restricted to a single room.
RF wireless music devices send the audio signal via radio waves. These radio wave signals can easily go through walls. The signal is broadcast either by utilizing FM transmission or digital transmission. The least expensive choice 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 noise or hiss and audio distortion. In addition, FM transmitter products are also quite prone to interference from other wireless transmitters. Digital wireless audio transmitter devices, such as products from Amphony, make use of a digital protocol. The audio is first converted to digital data before being transmitted. This method guarantees that the audio quality is entirely preserved. Some transmitters employ some form 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 highest fidelity.
Digital wireless audio transmitter products, such as products from Amphony, use a digital protocol. The audio is first converted to digital data before being transmitted. This conversion and transmission in the digital domain will guarantee that the original audio quality is maintained. However, this is only the case of the data is sent uncompressed. Some wireless audio transmitters will apply some type of audio compression. Such products include Bluetooth audio transmitters. Audio compression will degrade the quality of the audio to some extent.
Wireless LAN (WLAN) products are practical when streaming from a PC but will add some amount of latency or delay to the signal because wireless LAN was not originally designed for real-time audio streaming. WLAN receivers typically require purchasing a separate LAN card to be plugged into each receiver.
Powerline products employ the power mains to distribute audio and offer great range but run into trouble if there are individual mains circuits in the house 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 prevent audio dropouts, these products will normally have an audio latency of several seconds as a safeguard. Now we'll give you some suggestions for shopping for a wireless system: Go for a system that supports multiple wireless receivers if you plan to stream audio to several rooms so that you don't have to purchase a separate transmitter for every 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 audio transmitter to make sure that the audio quality is maintained. Make sure the audio delay is smaller than 10 ms if you have a real-time application such as video.
Select a transmitter that has all of the audio inputs you require, e.g. speaker inputs, RCA inputs etc. Choose a system where you can add receivers later on which offer all of the necessary outputs, e.g. amplified speaker outputs, RCA outputs etc. Because you may want to connect the transmitter to several sources, you should choose a transmitter that can be adjusted to different signal volume levels to prevent clipping of the audio signal inside the transmitter converter stage.
Make sure that the amplified wireless receivers contain built-in digital amplifiers with low distortion figures. This will keep the receiver cool due to high amplifier power efficiency and offer optimum 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 set up. 5.8 GHz wireless products typically have less trouble with interference from other wireless transmitters than products working at 900 MHz or 2.4 GHz.
