One to two desktop array square tube wireless speech conference microphone

5G-4GNH

Functional features:

1. Ultra wideband UHF645MHz~685MHz, automatic signal selection, true diversity reception with dual channel receiving circuit.

2. The true diversity receiving system adopts two receiving circuits with the same channel to reduce the noise and leakage caused by radio frequency interference.

3. Adopting a 6.3mm unbalanced output and XLR XLR balanced output synchronous output design, it is convenient to connect various audio processing devices.

4. It has the function of [AFS] automatic search for clean and interference free frequencies within a range of 1 kilometer. After short pressing the SC/LOCK button, it will automatically search and lock on channels that are not affected in the actual working environment. Align the transmitter's frequency window with the receiver's [IR], and immediately make the transmitter automatically and accurately lock the receiver's working frequency point.

5. It has the [IR] infrared automatic frequency matching function. Simply press the ▲ button briefly to enter the manual frequency modulation mode. Adjust the [ADJ/VOL] knob to the appropriate frequency point, press the ▲ button briefly to confirm, and then press the [SET] button briefly to perform frequency matching.

6. A spacious and clear 2-foot LCD display with independent single channel can view the battery level, frequency signal, signal strength, audio power and other information status of the wireless unit; All silicone light guide buttons, display simple and neat; Successfully connected the microphone, the host display screen changes color in two colors, making the working status clearer.

7. A stable PLL phase locked oscillation circuit, combined with the "digital pilot" mute control function and the "noise detection" mute control function, can effectively block the noisy RF interference of computer devices, jukeboxes, and DVDs in the working environment.

Integrating two wireless square column series desktop condenser microphones and brackets, it exudes a solemn and dignified atmosphere, showcasing a unique sense of nobility.

8. Dual head horizontal array technology, precise control of horizontal angle, avoidance of acoustic feedback, and avoidance of whistling.

9. An etched mesh cover that accurately calculates the diameter and spacing of holes, combined with interference correction technology, accurately controls every pickup detail and effectively improves the pickup sensitivity within the vocal range.

10. Zinc alloy integrated shell, effectively suppressing various types of electromagnetic interference.

11. The microphone switch uses automotive grade rubber switch buttons, which are durable and have a slight mechanical sound characteristic.

12. The integrated design structure of the microphone and base allows for easy and free adjustment in a vertical direction of 75 °.

13. The microphone is equipped with a built-in UHF confidentiality level high fidelity transmission module, providing high-quality wireless speech and conference scenes.

14. Customizable wired/wireless dual backup configuration.

15. It can be directly connected to the mixer and is widely used in high-quality occasions such as conferences, speeches, and teaching.
