T-68 Wireless System
User Manual
WP-68 wireless system uses UHF frequency band (630-690MHz) to work. There are 100 available working channels for receiving and transmitting audio without delay. Stable working distance is more than 20 meters, using intelligent energy-saving circuit, it can work continuously for more than 7 hours. UHF band has the advantages of good signal transmission stability, wider available radio frequency bandwidth, anti-WIFI and Bluetooth interference. T-68 wireless system, with built-in rechargeable lithium battery and battery management system, can be intuitive observation of battery power.
The background noise is very low when working, suitable for stage performances, recording, outdoor bands, personal performances, teaching and other occasions.
With user management function, when the system detects that the user has not used it within half an hour, it will automatically shut down the power supply. As to avoid the situation that the battery is short of electricity at the critical moment.
