Product Description:
The product selects an ultra-directional strong condenser cartridge, featuring extremely excellent sound quality and frequency response.
It adopts a lock-type firm plug-in separation structure, ensuring highly reliable and stable performance.
The independently designed new base is an ideal device for high-level conference projects with extremely high requirements.
It has a wide frequency response, clear and transparent sound quality, low noise, and the ON/OFF switch of the microphone has an extremely long service life.
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 affected by external interference.
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, is easy to operate, and has outstanding performance.
-
Adopts multi-stage narrowband high-frequency and intermediate-frequency frequency-selective filtering to fully eliminate interference signals.
-
Adopts audio compression and expansion technology, greatly reducing noise and increasing the dynamic range.
-
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 usage distance is 80 meters.
-
Built-in high-performance lithium battery, with a self-contained TYPE-C interface, which can be used while charging.
