Digital pilot Series induction microphone system characteristics

Industry pioneering automatic hand induction patent technology, the MIC will be mute automatically after leaving hands and being dormant for 3 seconds. (This is for any direction or any angle’s placing)

After 5 minutes, the MIC will automatically get into energy saving standby mode; and after 15 minutes, will automatically power off and completely turn off power supply. It is a new concept intelligent and automatic microphone.

- Bran-new audio circuit structure, high pitch is exquisite, the medium and low frequency is strong. Especially the sound has perfect expressive capacity on details. Super strong dynamic tracking ability makes it freely pick up voice with far or near distance.

- Bran-new concept digital pilot technology, completely solves string frequency phenomenon each other in KTV rooms, won’t happen string frequency forever.

- The configuration has the circuit of noise suppression function, can be debugged easily.

- Automatically search no-interference channel function, installation is more convenient.

- Flexible limitation of the output maximum volume, adapts to more big range.

- UHF frequency range, phase-locked loop (PLL) frequency synthesis

- 100 *2 signal channels, channel space is 250 KHZ

- Super heterodyne secondary frequency conversion design, has extremely high receiving sensitivity

- RF part adopts multilevel high-performance dielectric filter, owns good anti-interference ability.

- The first intermediate frequency adopts acoustic filters; the second intermediate frequency uses level 3 ceramic filters, efficiently improve the anti-interference ability

- The especially designed mute circuit completely eliminates the microphone’s impacting noise due to turn on and off.

- The microphone adopts readily available 5# batteries, last for 6-10 hours continuously.

- The microphone adopts unique step-up design; low quantity of battery charge does not affect the overall performance.

- The operating radius can reach 80 meters in ideal environment, suitable for all kinds of requiring place.

- The default configuration is with LCD blue backlight and aluminum alloy MIC duct body.

- Has adjustable transmitting power and adjustable noise threshold, There is external noise control knob on the rear panel of receiver, can according to need to freely set effective operating radius between 10m-80m.

- Has automatic Infrared to frequency function, can make the microphone rapidly synchronize with the receiver’s working signal channel.

- Special models for KTV engineering, two microphones, one host, easily configure more than 100 KTV rooms. The design of product’s structure is unique, maintenance is quick and easy.

Applicable occasions:

Apply high-grade KTV room, small and medium-sized performance classroom and meeting room etc. It is this year’s key new products, are extremely welcomed by customers.
