This product uses the ISM global unrestricted 2.4G frequency band for transmission. The receiver and transmitter are automatically paired successfully within 2 seconds after turning on. The transmission distance reaches 50 metres (clear line of sight) and 20 metres with obstructions. Both receiver and transmitter use clear and bright LED lights to display the current input and output audio dynamics. The output volume is adjustable and the 3.5mm TRS Jack output is used to connect to DSLR cameras, camcorders, recorders, tablets, mobile phones (type C and lightning). Furthermore a 6.35mm (1/4") Jack plug adapter included for connection to PA system, Mixers and other devices for high-fidelity wireless audio.
