Adhering to the stringent guidelines set by IEC60914 and GBT15381-94, ensuring a reliable and standardized performance.

Featuring an exclusive appearance design that exudes sophistication and elegance, aligning perfectly with modern aesthetic standards.

Each unit operates passively, relying on the system host for power supply. With an input voltage of 24V, the system ensures a safe and efficient operation.

The unit incorporates an advanced 8-core wire interface utilizing a T-shaped 8-core connecting wire. The inclusion of full aluminum foil and water line shielding significantly minimizes interference from strong electromagnetic waves, guaranteeing optimal signal transmission.

Employing meticulous calculations of hole diameter and spacing, coupled with interference correction technology. This precision ensures exceptional sensitivity in capturing every detail within the human voice range, resulting in superior audio pickup quality.

The unit's unique cavity design, combined with sophisticated pickup correction technology, faithfully reproduces even the most subtle sound details, delivering an immersive and high- fidelity audio experience.

With an integrated base and gooseneck design, the system offers a convenient and fixed installation solution, ensuring stability and ease of use.

Crafting from a single-piece zinc alloy shell, our units effectively suppress various types of electromagnetic interference, guaranteeing uninterrupted and pristine audio performance.

Equipping with a built-in high-fidelity/anti-cell phone signal interference capacitive tone head, our units effectively prevent interference from cell phones and other electronic devices, guaranteeing uninterrupted communication.

The unit's mute switch is designed with a soft texture, eliminating any mechanical noise when pressed, facilitating a seamless and distraction-free conference experience.

Featuring a bright and clear indicator ring, the unit provides visual cues during operation. The ring can be individually turned off as needed, ensuring flexibility and customization.

Integrating a high-quality capacitive microphone core, offering exceptional sensitivity and clarity in sound pickup, ensuring crystal-clear voice reproduction.

Incorporating state-of-the-art anti-interference circuitry, meticulously engineered to combat interference from cell phones and other electronic products, maintaining optimal audio quality.

The unit's light ring remains consistently red when a speaker is active, providing a clear visual indication to facilitate smooth and organized discussions.

The microphone switch operates silently without any mechanical key sound, ensuring a long lifespan and uninterrupted operation.

Featuring a 2.4-inch IPS TFT display, our units present crisp and detailed information. Users can easily access operating unit parameters, date and time, and speaking volume, enabling efficient monitoring of the system's current status.

The microphone units are equipped with a speaking timing function, allowing precise control over speaking time allocation during conferences.

The unit interface employs a closed-loop Ethernet link mode and supports "hand-held" connections, enabling convenient hot-swappable functionality for hassle-free installation and maintenance.

The chairman unit enjoys exclusive priority and control over the meeting order. It is not limited by the number of speakers, providing enhanced authority in managing conference proceedings.
