This series of products adopt ID identification technology, each channel has an ID code, strong anti-interference ability, suitable for all kinds of large, small and medium-sized conferences.
Two channels receive signals, each channel has 200 channels to choose from, each channel steps at 250KHz; Each channel uses 49.75MHz;
Adopt microprocessor control, PLL phase-locked loop frequency synthesis technology, the use of frequency is more flexible;
· UHF band transmission signal, common frequency range: 600MHz optional 500/700/800MHz;
The same occasion can be used for multiple simultaneous use (customized frequency up to 20 receivers and 40 transmitters at the same time)
· Each channel is equipped with an independent window, and the LCD screen displays multiple key information. The working status is clear at a glance, making operation and monitoring easy and convenient, thereby improving performance. Each channel is equipped with independent volume adjustment knob, infrared frequency signal lamp, one-key frequency button, frequency front and back adjustment button, channel power switch button;
2 rubber receiving antennas are set on the back of the receiver to enhance the received signal and have a decent appearance;
The back of the XLR independent balanced output and 6.3 unbalanced mixed output coexist, can adapt to various occasions of equipment connection, to avoid confusion and embarrassment caused by equipment connection mismatch;
· Interoperability in the 400 channels, showing the humanized high-tech design;
The appearance design of the microphone lengthens the pickup cavity, the high-fidelity unidirectional capacitive microphone core, the pickup distance is farther, up to 30-50CM; The sound is smooth, the reduction degree is high, and the noise is small;
The conference microphone tube adopts a 360-degree all-round rotation design and is detachable. The microphone head has a lamp ring to indicate the starting state;
The power consumption of the microphone is 80mA, and it is powered by a 1.5V battery (3 batteries), which can be used continuously for 10 hours;
Use distance: open environment: 80-100 meters complex environment: 50-80 meters
