16 channels UHF Wireless System for Fitness applications

WF-U4 FITNESS is the answer to freedom of movement needs and protection against moisture that must characterize a wireless microphone specifically designed for fitness and for all activities based on high physical activity. The other key features are the absolute ease of use and protection against interference, which are the real answer to those who have not much time for setting or sound check: just plug the receiver into a 6.3mm jack socket of your audio system, choose one of the 16 frequencies available and that's it. The WF-U4 FITNESS operates in the ISM-Europe band (863-865 MHz), which is free throughout Europe and does not require special permissions or licenses. Frequency selection is done via the DIP-switch on the receiver and via the infrared synchronization system on the transmitter. Finally, the system is equipped with a practical and sturdy case to protect the elements when not in use and easy transport.
