Handheld/Headset/Lavaliver option
Product features
1. Exquisite and elegant structural design, ergonomic and modern
2. UHF band is adopted and two / four channels are available, which has less interference and more reliable transmission than traditional VHF band
3. The built-in frequency automatic scanning function of the wireless receiver can search and lock the non-interference frequency in the working state, and automatically select the most ideal working channel.
4. The front shuttle knob is designed to replace the traditional complex keys and cooperate with the full-color 1.77-inch TFT full-color LCD screen, which is fast and easy to operate
5. Using stable PLL phase-locked frequency oscillation circuit technology, the tuning frequency is adjustable, and the infrared frequency can lock the transmitter frequency quickly and accurately
6. It integrates the overall control of CPU and digital LCD interface display, which is convenient to operate and outstanding in performance.
7. Multiple noise monitoring circuits and special tone locked tone-locked system make it have excellent anti-interference characteristics.
8. Electronic 10 level volume output control is adopted, which makes the operation more clear and intuitive, and is convenient for higher-level adjustment of the engineering system.
9. The wireless receiver adopts electronic 0 to - 60dB sensitivity adjustment control, which makes the operation more clear and intuitive and can be used in various occasions.
10. The wireless receiver can choose the bilingual interface in Chinese and English, which can be used in various occasions.
11. Provide 200 adjustable frequencies for each and a total of 200 channel choices to effectively avoid frequency interruption.
12. Each channel has an independent balanced output port to adapt to different equipment connection requirements.
13. One click infrared frequency matching function can easily and quickly synchronize the frequency of transmitter and receiver.
14. Use the audio circuit to restore the real sound efficiently, with high fidelity, fine sound quality and not easy to scream.
15. The receiving distance (in open space) is about 50m-100m, and the specific distance depends on the actual use environment.
16. Built in effective filtering sponge to effectively filter noise.
17. The receiver adopts multistage audio amplification and has high sensitivity.
18. Combined with wireless amplification system, it can realize full coverage of wireless signals in the use site.
19. Optional 4.3-inch touch microphone, 2.4-inch color screen microphone, handheld microphone, headset microphone and Lavalier microphone.
20. According to the wireless matching scheme, it can be widely used in conferences, speeches, teaching and other occasions.
