Advanced wireless microphone1/4

Release Time：2024-08-14 04:10:09 View：1409

Product Description:
The product selects an ultra-directional strong capacitive cartridge, which has extremely excellent sound quality and frequency response.
It adopts a lock-type firm plug-in separation structure to ensure highly reliable and stable performance.
The independently designed new base is an ideal device for advanced conference projects with extremely high requirements.
It has a wide frequency response, clear and transparent sound quality, low noise, and an ultra-long service life of the microphone ON/OFF.
When the microphone is turned on, the red working indicator light of the cartridge lights up.
The gooseneck and the base are separable and suitable for large, medium, and small conferences, public communication, classes, speeches and other occasions.
It is identified by ID code and is not easily disturbed or affected by the outside world.

Main features:

Uses the UHF 640~690MHZ frequency band, applies PLL frequency synthesis phase-locked loop technology, the frequency is adjustable, and 5 sets can be used simultaneously without interference.
Integrates the overall control of the central processing unit CPU, cooperates with the digital liquid crystal interface display, easy to operate and outstanding performance.
Adopts multi-stage narrowband high-frequency and intermediate-frequency selective filtering to fully eliminate interference signals.
Adopts audio compression and expansion technology, greatly reduces noise and increases the dynamic range.
It is equipped with a feedback howling suppression and attenuation function, which can effectively reduce feedback howling.
The receiver adopts multi-stage high-frequency amplification and has extremely high sensitivity.
The ideal space use distance is 80 meters.
Built-in high-performance lithium battery, with a TYPE-C interface, and can be used while charging
