Product Description
Features :
- Dual wireless microphones with one receiver.
- Long battery life with booster battery function, can keep up 6-10 hours and will not affect the stability even when battery is low.
- Special circuit designed to cut of sound completely when dropping to avoid loud feedback from speakers.
- Approximate working distance is 300 ft.
- Energy saving with ECO-MODE
- Automatic transferring to energy saving mode after 5 minute unused.
- Automatic shutting down after 30 minutes unused to avoid over heat and save energy.
- Super strong dynamic tracing ability providing a perfect sound regardless far or near distance.
- Anti-interference ability with new digital pilot technology to avoid string frequency when many microphones being used.
- Easy install, IR auto frequency pick up, and high receiving sensitivity to provide a perfect sound for any KTV bars, karaoke rooms, classrooms, concerts, meeting rooms and etc.
