UHF Dual Digital Wireless Microphone System

SOUNDSATION WF-D290 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 transmitters and receiver, such as battery level, transmission power, squelch operation, etc. The system is 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 for each transmitter, divided into 10 groups, each of which contains 9 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 (in case of WF-D290HP), however, are equipped with LCD display with auto-off function, to save battery. 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, there are two optional kit for rack mounting of 1 or 2 receivers, respectively, on 1 or 2 standard 19" rack units.
