Industry automatic induction hand patent technology, left hand phone still within 3 seconds after automatic mute (any direction, at any Angle Can be), automatic energy saving into standby mode after 5 minutes, 15 minutes after the automatic shutdown and completely cut off the power supply, is a new The concept of intelligent, automated wireless microphone
new audio circuit structure, the high is exquisite, the low frequency is strong, especially on the details of sound with perfect performance.super Strong dynamic tracing ability makes far/near distance easy pick up charge
- a new concept of digital pilot technology, completely solve KTV rooms each string frequency phenomenon, never string frequency!
- configuration has the noise suppression function circuit, debugging easier
- automatic search no interference channel function, installation more convenient
- free to limit output maximum volume, adapt to the range
- UHF frequency band, phase-locked loop (PLL) frequency synthesis
- 100 * 2 channel, channel spacing 250 KHZ
- superheterodyne secondary frequency conversion design, have extremely high receiving sensitivity
- rf part adopts multilevel high-performance medium filter, good anti-interference ability
- the first intermediate frequency acoustic filters, the second intermediate frequency use level 3 ceramic filter, very good to improve the anti-interference ability
- especially the mute circuit design, completely eliminate the microphone turned on and off the I mpact of the noise
- the microphone use tesco 5 batteries, with up to 6-10 hours
- the microphone adopts unique design of booster battery down does not affect the hand cannot overall performance
- the ideal environment for operating radius of 80 meters, suitable for all kinds of requirements
- the default configuration for LCD backlight blue, mike duct aluminum alloy body
- have adjustable adjustable transmission power and noise threshold, after receiver panel is set external noise control knob, can be in 10 meters
- according to need Flexible setup effective radius of operation between 80 metres
- have ir automatic frequency function, can make the microphone to work fast synchronization and receiver channel
- KTV engineering special models, two microphone, a host.Easily configure more than 100 KTV rooms, the product structure design is unique,Ouick and easy maintenance.
Applicable occasions: suitable for high-grade KTV room, small and medium-sized performances, classroom, meeting room, etc., is this year's key new products, are extremely
Customer welcome.Packing type: conventional color box packaging (see sample)
