This really is an incredibly cost-effective option for anyone needing an audio kit to do high-fidelity audio recordings. Especially versatile as the transmitter can take “mic in” or “line in” audio, expanding the number of ways this system is useful.

 

 

The receiver can be connected to digital cameras, camcorders, recorders, tablet computers and other devices. It makes use of mini-jack audio connectors, and the necessary cable is included. There is an additional cable to connect the receiver to smart phones which make use of a mini-jack input port (3.5mm interface with TRRS connector). The receiver has an output for headphones as well, which is a useful feature missing on some far more expensive systems. If you are wanting a kit which you can expand by adding a second transmitter, you can buy this kit here and upgrade to 2 transmitters when you are ready.

 

 

Designed to be extremely simplistic and easy to use, while still having features some other brands don’t even include.

There is a headphone out port allowing real-time monitoring of your audio. The receiver supports headphone and output volume adjustment. So, there are many features making this a worthwhile choice.

 

Using a wireless audio system gives you greater freedom of movement. It also means you don’t need to have long runs of cabling anywhere. The working range of this system is about 80 meters. To keep your audio clean the system makes use of Digital audio compression, this DSP reduces the noise in wireless transmission system to the lowest level. To reduce the risk of interference, the units are switchable to 10 different frequencies. Both the receiver and transmitter are powered by two AA batteries each. These make running the system cheap as the batteries are so easily available everywhere.
