More and more wireless audio transmitter devices have emerged recently, promising the ultimate freedom to broadcast music throughout the house.We will look at different products and technologies to understand how effective these products are for the wholeHome audio apps and precautions when purchasing a wireless system.Infrared wireless audio products are limited to line-of-Visual application, I.
e.
It is only operated in one room because the signal is broadcast as an infrared light that cannot penetrate the wall.This technology is often found in wireless speaker kit products.RF wireless products will broadcast signals in the form of RF waves.
These waves can pass through the walls without difficulty.RF wireless audio devices can be transmitted using FM or digital audio.FM transmitter is the cheapest option.They provide a good range, but the music signal is prone to audio distortion and hissing and is very vulnerable to interference from other wireless transmitters.
Products that use digital wireless audio transmission, such as Amphony audio transmitter products, convert audio to digital signals using a digital protocol before transmission.The conversion and transmission of this digital domain will ensure that the original audio quality is maintained.On the other hand, this is just the case where the data is sent uncompressed.
Some wireless audio transmitters will apply some type of audio compression.These products include Bluetooth audio transmitters.Audio compression reduces audio quality to a certain extent.
The wireless LAN (WLAN) product is useful when streaming from PC, but will add a certain delay or delay to the signal, because the wireless LAN is not originally for real-Time audio stream.A wlan receiver usually needs to purchase a separate LAN card to insert each receiver.Power line products broadcast audio via power and provide a wide range.
They had trouble in houses with independent power circuits because they were able to cross into another circuit.There is another problem with power line products in the form of surge and spikes, which may cause transmission errors.To prevent the loss of audio, as a protective measure, these products usually have a few seconds of audio delay.
Now, we will provide you with some guidelines for purchasing wireless systems: If you plan to stream audio to multiple rooms so that you do not have to purchase a separate transmitter for each receiver, please select a system that supports multiple wireless receivers.Products with some form of error correction will be more resistant to radio interference from other wireless transmitters.Select a digital RF audio transmitter to ensure the audio quality is maintained.
Make sure the audio delay is less than 10 MS if you have real audio delayTime applications such as video.Select the transmitter with all the audio inputs you need, E.G.g.Speaker input, RCA input, etc.Make sure you can purchase additional receivers later when you expand your system.
Verify that you can get the receiver with speaker output for connecting the normal speaker as well as the receiver with the lineHorizontal RCA output.Since you may want to connect the transmitter to several sources, you should choose a transmitter that can be adjusted to different signal volumes to prevent the cutting of audio signals within the transmitter converter level.Make sure the enlarged wireless receiver is built in-In a digital amplifier with low distortion numbers.
Due to the high power efficiency of the amplifier, this will keep the receiver cool and provide the best sound quality.Make sure the receiver is able to drive the speaker at the ohm rating you like.Choosing a product with a small footprint and convenient installation of a wireless receiver will help with the installation process.
Use less crowded equipment.
The 8 GHz band usually has less wireless interference than 900 MHz or 2 GHz.4 GHz products
