Dual-diaphragm Conference Unit with 2.4G/UHF Dual-engine Wireless Microphone HY-5730C HY-5730D

- Adopts DSP/DDOV digital processing and transmission technology, compliant with the IEC60065 international standard;

- Complies with GB4943.1-2022 safety requirements standard for audio-visual, information technology and communication technology equipment;

- Built-in 2×14mm high-fidelity gold-plated capacitive dual-diaphragm pickup, significantly reducing background noise and improving signal-to-noise ratio and pickup clarity;

- Unique cavity and integrated molded pickup steel mesh design, precisely controlling the pickup angle and avoiding acoustic feedback and howling;

- The microphone boom uses 32,500 high-density sound interference holes with a diameter of 0.4mm, effectively improving the pickup sensitivity in the human voice frequency range;

- High-sensitivity pickup design, built-in automatic gain control (AGC) function, effective pickup distance up to 60-100cm;

- Equipped with a microphone noise suppression circuit system, using a fifth-order Butterworth low-pass filter voice noise reduction method to process the sound signal;

- Adopts a gravity-sensing touch-sensitive chip, with an elliptical track indicator light display, high-quality aluminum alloy embedded with a Mohs hardness 6-grade touch glass panel, no mechanical buttons, and no button sound during switching;

- Equipped with a 3.5" high-brightness LCD screen, supporting information such as battery level, signal, ID address, volume, transmission power, and speaking time;

- Full-digital DSSS modulation communication technology, ISM and UHF dual-engine frequency bands, voice data interaction through wireless transceivers, ensuring audio delay is less than 5.5ms;

- Uses 128-bit AES Rijndael and 48-bit PIN code encryption protection to prevent eavesdropping and unauthorized access, ensuring the privacy of the meeting;

- Automatically identifies the frequency of interference sources in the full frequency range, and automatically switches to an interference-free frequency range to ensure real-time normal communication of the system;

- Adopts digital ID addressing method, allowing custom ID numbers to ensure a unique ID code;

- The conference unit has independent adjustable RF radio frequency power, with low, medium, and high settings;
- The system host allows setting and modifying unit identities; chairman, VIP, and delegate unit identities can be reassigned and configured as needed;

-  In conjunction with an HD camera, it supports automatic tracking and picture switching during speeches, and also supports picture freezing;

- It features two working modes: first-in, first-out and limited number of speakers, with the number of speakers configurable to 1/2/3/4;

- Built-in 3000mA/H rechargeable battery with dynamic power display and low battery warning function, supporting 10 hours of use;

- Features wireless charging, completely eliminating the constraints of charging cables and addressing the problem of insufficient power during long meetings;

- Designed with advanced electrostatic isolation technology, preventing static electricity even in dry environments and regions;

- Supports connecting up to 4 chairman units, with the chairman having control over the proceedings and priority speaking rights, and the ability to mute other speaking delegates;

- Equipped with a set of volume buttons, allowing for 8 levels of independent volume adjustment for each conference unit;

- Features one TYPE-C interface, supporting adapters, charging boxes, and wireless charging, allowing for program upgrades and maintenance without disassembling the device;
