More and more wireless audio transmitter products promise the ultimate freedom in streaming music everywhere in the house. We are going to check out different products and technologies to determine in the length of time these items are of help for whole-house audio applications and just what to look out for when purchasing a wireless system.
Running music at your residence could be a daunting task. Many homes are not wired for multi-room audio and having the songs out of your living room to your bedroom is usually a challenge. Items that solve this problem are often using the following technologies: infrared wireless, RF wireless, wireless LAN or powerline.
Infrared wireless audio products are tied to line-of-sight applications, i.e. only operate within a single room since the signal is transmitted as infrared light which cannot penetrate walls. Fractional treatments is frequently found in wireless speaker kit products.
RF wireless audio products send the audio signal via radio waves. These radiation signals can certainly proceed through walls. The signal is shipped either through the use of FM transmission or digital transmission. FM transmitters are the most inexpensive option. They feature good range but the audio signal is prone to audio distortion and noise and is also very prone to interference from other wireless transmitters.
Digital wireless audio transmitter products employ a digital protocol. The audio is first changed to digital data prior to being transmitted. This method makes sure that the audio quality is fully preserved. Some transmitters use kind of audio compression, including Bluetooth transmitters, which will degrade the audio to some degree. Transmitters which send the audio data uncompressed will achieve the highest fidelity.
Products using wireless LAN are of help when streaming audio from the PC. Their drawback is because they normally have some fairly high latency, i.e. the signal will likely be delayed by some amount since wireless LAN wasn’t created for real-time audio streaming. Also, some products require to buy separate wireless LAN modules which might be connected each audio receiver.
Powerline products send the audio via the power mains and gives great range. They come across problems in houses where you can find separate mains circuits in terms of to be able to overlap into another circuit. Also, they build within a delay of countless seconds to defend against transmission errors during power surges and spikes which prevents their use within applications in which the audio from wireless speakers should be in sync to non-wireless speakers or video.
Below are great tips for choosing a wireless speakers: If you are planning to stream audio into several rooms of your dwelling, make sure you decide on a system that permits streaming to multiple receivers as well. Like that you don’t have to buy a separate transmitter per receiver that you are streaming to. Some products possess some way of error correction integrated which will help guard against dropouts in the event of strong wireless interference. Choose a digital RF audio transmitter to ensure the audio quality is preserved. Make sure the audio latency is lower than 10 ms for those who have a real-time application for example video.
Decide on a transmitter that has each of the audio inputs you will need, e.g. speaker inputs, RCA inputs etc. Select a system which you could add receivers afterwards which provide each of the required outputs, e.g. amplified speaker outputs, RCA outputs etc. If you go with a digital audio transmitter, choose one with the input audio level control knob to stop the audio signal from clipping in the transmitter audio converter. This can ensure optimum dynamic range whatever the signal amount of your equipment.
Make certain the amplified wireless receivers have built-in digital amplifiers with low distortion figures. This will maintain the receiver cool as a result of high amplifier efficiency and provide optimum sound quality. Ensure that the receivers can drive speakers along with your desired Ohm rating. Picking a product in which the wireless receivers have a small footprint and easy mounting options can help through the installation. Items which are employed in the 5.8 GHz frequency band may have less difficulties with wireless interference than products while using crowded 900 MHz or 2.4 GHz frequency band.
