A lot more wireless audio transmitter products promise the ultimate freedom in streaming music everywhere in the house. We’ll examine different products and technologies to learn in how long the products are useful for whole-house audio applications along with what to look for when purchasing a radio system.
Running music within your house can be quite a daunting task. Many homes are not wired for multi-room audio and having the songs from the living room in your bedroom could be a challenge. Products which solve this problem usually are based on the following technologies: infrared wireless, RF wireless, wireless LAN or powerline.
Infrared wireless audio items are limited by line-of-sight applications, i.e. only operate in just a single room since the signal is sent as infrared light which cannot penetrate walls. This technology is often 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 distributed either through the use of FM transmission or digital transmission. FM transmitters would be the most affordable option. They offer good range however the audio signal is vulnerable to audio distortion and noise and is also very prone to interference from other wireless transmitters.
Digital wireless audio transmitter products start using a digital protocol. The audio is first converted to digital data before being transmitted. This technique helps to ensure that the audio quality is fully preserved. Some transmitters apply certain kind of audio compression, including Bluetooth transmitters, that may degrade the audio to some degree. Transmitters which send the audio data uncompressed will achieve the highest fidelity.
Products using wireless LAN are useful when streaming audio from the PC. Their drawback is they routinely have some fairly high latency, i.e. the signal is going to be delayed by a few amount since wireless LAN had not been created specifically for real-time audio streaming. Also, some products require to acquire separate wireless LAN modules which might be attached to each audio receiver.
Powerline products send the audio through power mains and give great range. They come across problems in houses where there are separate mains circuits when it comes to having the capacity to overlap into another circuit. Also, they build in the delay of several seconds to safeguard against transmission errors during harmful electrical currents and spikes which prevents their utilization in applications where the audio from wireless stereo speakers should be synchronized to non-wireless speakers or video.
Below are great tips for picking a wireless audio system: If you plan to stream audio into several rooms of your dwelling, be sure you go with a system which allows streaming to multiple receivers as well. That way you won’t need to obtain a separate transmitter for each receiver that you are streaming to. Some products have some form of error correction built in which will help guard against dropouts in case there is strong wireless interference. Look for a digital RF audio transmitter to make sure that 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.
Select a transmitter which has each of the audio inputs you may need, e.g. speaker inputs, RCA inputs etc. Go with a system to add receivers later on which offer every one of the required outputs, e.g. amplified speaker outputs, RCA outputs etc. In case you decide on a digital audio transmitter, choose one with an input audio level control knob to avoid the audio signal from clipping inside the transmitter audio converter. This may ensure optimum dynamic range whatever the signal a higher level your equipment.
Make sure that the amplified wireless receivers have built-in digital amplifiers with low distortion figures. This will likely keep the receiver cool as a result of high amplifier power use and still provide optimum audio quality. Guarantee the receivers can drive speakers with your desired Ohm rating. Choosing a product the location where the wireless receivers have a small footprint as well as simple mounting options might help during the installation. Products that are employed in the 5.8 GHz frequency band could have less issues with wireless interference than products while using the crowded 900 MHz or 2.4 GHz frequency band.
