MBD 780 - double wireless microphone

The wireless system works in UHF band, true diversity, FM modulation(F3E), there is a compounder and a noise gate, the choice of frequency work among 100 channels. The receiver with XRL balance outputs separately for every channel and unbalanced Jack 6,3- summing signals from both channels. The news is that synchronization of chosen channel between the transmitter and the receiver is based on the infrared. The microphones have the CE certificates and comply with URTiP requirements.


The receiver
• True diversity, UHF, 2 channels
• Infrared frequency synchronization
• Scan function
• Indicators 2* tuned to the transmitter, 2*audio signal, 2*tuning frequency
• Backlit LCD display
• The sound level regulation
• Compressor, expander, 2 squelch
• Independent balanced outputs XLR and summing unbalanced Jack 6,3
• Level of balanced outputs 300mV, asymmetric +_ 150mV, balanced 10kohl
• Independent squelch setting for each channel
• Frequency of work 750-780 Hz in maximum of 100 available frequencies. It eliminates problems with interruptions of wireless systems as well as in the others wireless systems working at the same time. Frequency settings can be done manually by choosing one of the 100 channels frequencies from transmitter or receiver. The settings can be done automatically by searching for free frequency and synchronize it with infrared.
