Product Description:
The product selects a super-directional strong condenser capsule, featuring extremely excellent sound quality and frequency response.
It adopts a lock-type firmly pluggable and detachable 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 microphone ON/OFF has a long service life.
When the microphone is turned on, the red working indicator light of the capsule lights up.
The gooseneck and the base can be separated and are suitable for large, medium, and small-sized conferences, public communication, classes, speeches, and other occasions.
ID code identification, not easily affected or interfered by the outside.
Main Characteristics:
-
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.
-
Integrated with the overall control of the central processing unit CPU, combined with the digital liquid crystal interface display, easy to operate and 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, significantly reducing noise and increasing the dynamic range.
-
Equipped with 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 its own TYPE-C interface, which can be used while charging.
