An increasing number of wireless audio transmitter products promise the best freedom in streaming music all around the house. We are going to have a look at different products and technologies to learn in what lengths these products are useful for whole-house audio applications and just what to look out for when selecting an invisible system.

Running music within your house can be a daunting task. Many homes are not wired for multi-room audio and getting the music from a living room for your bedroom is definitely a challenge. Items which solve this problem are often based on the following technologies: infrared wireless, RF wireless, wireless LAN or powerline.

Infrared wireless audio merchandise is limited to line-of-sight applications, i.e. only operate in a single room because the signal is sent as infrared light which cannot penetrate walls. Fractional treatments is frequently present in wireless speaker kit products.

RF wireless audio products send the audio signal via radio waves. These radio wave signals can certainly go through walls. The signal is shipped either by making use of FM transmission or digital transmission. FM transmitters are the most inexpensive option. They feature good range nevertheless the audio signal is vulnerable to audio distortion and noise and is also very prone to interference off their wireless transmitters.

Digital wireless audio transmitter products employ a digital protocol. The audio is first converted to digital data prior to being transmitted. This method helps to ensure that the audio quality is fully preserved. Some transmitters use some form of audio compression, such as Bluetooth transmitters, that will degrade the audio to varying degrees. Transmitters which send the audio data uncompressed will reach the highest fidelity.



Products using wireless LAN are useful when streaming audio coming from a PC. Their drawback is that they typically have some fairly high latency, i.e. the signal will probably be delayed by a few amount since wireless LAN wasn't created specifically for real-time audio streaming. Also, some products require to acquire 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 come upon problems in houses where there are separate mains circuits in terms of being able to overlap into another circuit. Also, they build inside a delay of several seconds to safeguard against transmission errors during power surges and spikes which prevents their used in applications in which the audio from wireless stereo speakers must be in sync with non-wireless speakers or video.

Here are some tips for picking a wireless head unit: If you're going to stream audio into several rooms of your property, make sure to pick a system that enables streaming to multiple receivers as well. That way you don't need to buy a separate transmitter per receiver that you will be streaming to. Some products involve some form of error correction internal which supports 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. Guarantee the audio latency is less than 10 ms in case you have a real-time application including video.

Decide on a transmitter which has all the audio inputs you'll need, e.g. speaker inputs, RCA inputs etc. Go with a system to add receivers down the road which provide each of the required outputs, e.g. amplified speaker outputs, RCA outputs etc. Should you decide on a digital audio transmitter, choose one with the input audio level control knob to prevent the audio signal from clipping inside the transmitter audio converter. This can ensure optimum dynamic range no matter the signal a higher level your equipment.

Make sure that the amplified wireless receivers have built-in digital amplifiers with low distortion figures. This can maintain the receiver cool due to high amplifier power efficiency and offer optimum audio quality. Ensure the receivers can drive speakers along with your desired Ohm rating. Deciding on a product the location where the wireless receivers possess a small footprint and easy mounting options might help during the installation. Products that operate in the five.8 GHz frequency band will have less difficulty with wireless interference than products while using crowded 900 MHz or 2.4 GHz frequency band.
