DB TECHNOLOGIES MOVING ONE-B B3

​UHF Diversity Wireless Microphone System 
Pocket transmitter + Headset mic 
Moving one combines the best of analog tradition with the contribution of digital technology. 
It provides a more noise-free and interference-free audio signal in any situation. 
Digital Code Squelch Technology 
In addition to the audio data, the system handles further telemetry information, like system on/off and charge level of transmitter battery. 
Automatic free-frequency research 
- The system automatically searches for free frequencies and, in case of disturbed channels, a LED flashes indicating the presence of interference 
- The selected frequency of the receiver is then sent to the transmitter via infrared with a simple operation 
•Up to 8 channels per band can run simultaneously without interference 
•It is possible to increase the number of channels by using multiple bands 
•Digital Code Squelch for extremely quiet power on/off operation and no squelch adjustments needed
