90-channel UHF Digital Wireless System with Bodypack and Headset Microphone

WF-D190 MKII adopts a brand-new digital transmission technology and hardware encryption of audio data that enable superior audio quality compared to analog UHF systems, very-low latency (better than 2.4GHz systems) and maximum security due to the cryptographic hardware. The unique 16bit digital ID pilot technology avoids interferences even on same frequency, and allows continuous exchange of data between transmitter and receiver, such as battery level, transmission power, squelch operation, etc. The system is also equipped with automatic frequency scanning and frequency spectrum display, which allow the user to select the less disturbed frequencies in every environment it operates. It features 90 frequencies, divided into 15 groups, each of which contains 6 channels. The user interface is very simple and intuitive, thanks to the TFT color display on the receiver and the simplicity of its setup menus. The handheld transmitter and the bodypack, however, are equipped with LCD display with auto-off function, to save battery consumption. The handheld microphone is also equipped with rechargeable lithium battery that can be recharged via the USB port on the back of the receiver.Finally, two 19" rack mount kit are available to install 1 or 2 receivers, respectively, in 1 or 2 rack units.
