Progressively more wireless audio transmitter products promise the ultimate freedom in streaming music all over the house. We’ll check out different products and technologies to determine in the length of time these items are useful for whole-house audio applications as well as what to look out for when buying a radio system.
Running music at your residence is usually a daunting task. Many homes are not wired for multi-room audio and becoming the songs from the lounge on your bedroom could be a challenge. Products which solve this concern are often based on the following technologies: infrared wireless, RF wireless, wireless LAN or powerline.
Infrared wireless audio goods are limited by line-of-sight applications, i.e. only operate within a single room since signal is shipped as infrared light which cannot penetrate walls. Fractional treatments is often found in wireless speaker kit products.
RF wireless audio products send the audio signal via radio waves. These radiation signals can readily go through walls. The signal is transmitted either by using FM transmission or digital transmission. FM transmitters are the most affordable option. They feature good range however the audio signal is vulnerable to audio distortion and noise and it is very susceptible to interference off their wireless transmitters.
Digital wireless audio transmitter products employ a digital protocol. The audio is first changed into digital data before being transmitted. This technique makes sure that the audio quality is fully preserved. Some transmitters apply kind of audio compression, for example Bluetooth transmitters, that can degrade the audio rather. 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 typically have some fairly high latency, i.e. the signal will likely be delayed by some amount since wireless LAN has not been specifically made for real-time audio streaming. Also, some products require to purchase separate wireless LAN modules which are plugged into each audio receiver.
Powerline products send the audio through the power mains and gives great range. They run into problems in houses where you can find separate mains circuits in terms of being able to go over into another circuit. Also, these products build in the delay of several seconds to shield against transmission errors during harmful electrical currents and spikes which prevents their use in applications where the audio from wireless stereo speakers must be synchronized along with other non-wireless speakers or video.
Below are great tips for deciding on a wireless speakers: If you’re going to stream audio into several rooms in your home, make sure to pick a system which allows streaming to multiple receivers at the same time. This way you won’t need to purchase a separate transmitter for every receiver you are streaming to. Some products have some form of error correction integrated which assists guard against dropouts in case of strong wireless interference. Look for a digital RF audio transmitter to ensure the audio quality is preserved. Guarantee the audio latency is under 10 ms when you have a real-time application like video.
Go with a transmitter which has all of the audio inputs you’ll need, e.g. speaker inputs, RCA inputs etc. Select a system to add receivers at a later date that provide every one of the required outputs, e.g. amplified speaker outputs, RCA outputs etc. In the event you decide on a digital audio transmitter, select one by having an input audio level control knob in order to avoid the audio signal from clipping inside transmitter audio converter. This may ensure optimum dynamic range no matter the signal a higher level your equipment.
Be sure the amplified wireless receivers have built-in digital amplifiers with low distortion figures. This may keep your receiver cool as a result of high amplifier power efficiency and still provide optimum quality of sound. Ensure the receivers can drive speakers along with your desired Ohm rating. Selecting a product the place that the wireless receivers use a small footprint and straightforward mounting options will help through the installation. Products that be employed in the five.8 GHz frequency band may have less issues with wireless interference than products while using crowded 900 MHz or 2.4 GHz frequency band.
