Product Detail
The product selects the ultra-directional strong condenser head, has the extremely excellent sound quality and frequency response.
The second use of the locking type solid plug separation structure, to ensure a high degree of stability and reliability.
Independent design of the new base, is the ideal equipment for demanding high-level conference projects.
Wide frequency response, clear and transparent sound quality, low noise, microphone ON/OFF long life.
When the microphone is switched on, the red working indicator of the head lights up.
Gooseneck and base can be separated type, suitable for large, medium and small meetings, public communication, classes, speeches and other occasions.
ID code identification, not easily affected by external interference and influence.
Main features:
*Use UHF600~650MHz frequency band, application of PLL frequency synthesis phase-locked loop technology, frequency adjustable, can be used at the same time 5 sets, without interference.
*Integrated central processor CPU total control, with digital high-definition LED interface display, easy to operate, outstanding performance.
*Adopting multi-stage narrow-band high-frequency and mid-frequency frequency selective filtering, fully eliminating interfering signals.
* Adopt audio compression extension technology, noise is greatly reduced, the dynamic range is increased.
*With return transmission whistle suppression and attenuation function, can effectively reduce the return transmission whistle.
*Receiver adopts multi-stage high-frequency amplification, with extremely high sensitivity.
*Ideal space use distance of 50 metres.
