Thinuna UR-400 Long-distance diversity wireless conference microphone
Features:
Adopt 2U standard chassis. System menu color large screen display, true diversity receiver.
Adopting diversity receiving technology, the signal is more stable, the receiving distance is farther, and the application is wider.
Four-channel independent frequency selection system, can be greater to reduce the occurrence of broken frequency.
Independent LED lights show the working status of each channel RF and audio, more intuitive.
Four-channel volume independently adjustable, SQ independently adjustable.
IR infrared frequency matching independent control.
Provide 4+2 audio output mode, greatly facilitate the user's daily use.
RF transmission frequency range: 640-690MHz.
Working range: 50 meters under typical conditions and 200 meters at outdoor straight-line distance (the actual working range depends on the absorption, reflection and interference of RF signal).
The working frequency of the system is set to 4x100 frequency points, and each channel is equipped with 100 frequency points adjustable.
Noise lock squelch control + tone code navigation lock squelch control.
Audio dynamic expansion and automatic level control circuit.
