    More and more wireless audio transmitter products promise the ultimate freedom in streaming music all around the house. We are going to have a look at different products and technologies to find out in how far these items are helpful for whole-house audio applications and just what to watch out for when purchasing an invisible system.

    Running music in your own home can be quite a daunting task. Many homes usually are not wired for multi-room audio and achieving the music from a family room on your bedroom is usually a challenge. Items which solve this challenge are generally in line with the following technologies: infrared wireless, RF wireless, wireless LAN or powerline.

    Infrared wireless audio goods are limited to line-of-sight applications, i.e. only operate within a single room because the signal is transmitted as infrared light which cannot penetrate walls. This technology can often be seen in wireless speaker kit products.

    RF wireless audio products send the audio signal via radio waves. These radio wave signals can simply go through walls. The signal is shipped either by utilizing FM transmission or digital transmission. FM transmitters would be the least expensive option. They have good range nevertheless the audio signal is susceptible to audio distortion and noise and is very prone to interference using their company wireless transmitters.

    Digital wireless audio transmitter products start using a digital protocol. The audio is first transformed into digital data before being transmitted. This process helps to ensure that the audio quality is fully preserved. Some transmitters use some kind of audio compression, including Bluetooth transmitters, that may degrade the audio to some extent. Transmitters which send the audio data uncompressed will achieve the highest fidelity.

    Products using wireless LAN are useful when streaming audio from your PC. Their drawback is that they typically have some fairly high latency, i.e. the signal will probably 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 attached to each audio receiver.

    Powerline products send the audio via the power mains and offer great range. They come across problems in houses where there are separate mains circuits when it comes to to be able to go over into another circuit. Also, they build in a delay of countless seconds to safeguard against transmission errors during power surges and spikes which prevents their utilization in applications the place that the audio from wireless speakers must be in sync with other non-wireless speakers or video.

    Below are great tips for choosing a wireless audio system: If you are planning to stream audio into several rooms in your home, be sure to decide on a system that permits streaming to multiple receivers as well. That way you won’t need to obtain a separate transmitter per receiver that you will be streaming to. Some products incorporate some kind of error correction built in which supports guard against dropouts in case of strong wireless interference. Choose a digital RF audio transmitter to ensure the audio quality is preserved. Ensure that the audio latency is less than 10 ms when you have a real-time application for example video.

    Decide on a transmitter which includes all of the audio inputs you may need, e.g. speaker inputs, RCA inputs etc. Choose a system where one can add receivers later on that provide each of the required outputs, e.g. amplified speaker outputs, RCA outputs etc. In case you decide on a digital audio transmitter, choose one by having an input audio level control knob to prevent the audio signal from clipping inside transmitter audio converter. This can ensure optimum dynamic range whatever the signal a higher level your equipment.

    Check that the amplified wireless receivers have built-in digital amplifiers with low distortion figures. This will likely maintain your receiver cool because of high amplifier efficiency and offer optimum sound quality. Make sure the receivers can drive speakers using your desired Ohm rating. Picking a product the place that the wireless receivers use a small footprint as well as simple mounting options will help through the installation. Items which are employed in the five.8 GHz frequency band will have less difficulties with wireless interference than products while using crowded 900 MHz or 2.4 GHz frequency band.
