Dual-diaphragm Wireless Conference Microphone WiFi+UHF Design HY-ST20CW HY-ST20DW

-- Utilizing a multi-channel WiFi + UHF 4-channel design and high-precision phase-locked loop (PLL) frequency synthesis technology for more stable transmission.

-- The aluminum alloy panel is embedded with a Mohs hardness level 6 touch glass panel, which is waterproof and dustproof to prevent tea spills during meetings from affecting the normal use of the equipment.

-- Equipped with a 3.5" LCD high-brightness touch screen, supporting Chinese, English and Russian, and can display system signals, channels, ID addresses and speaking time;

-- Utilizes the 630-690MHz frequency band, offers 5 selectable WiFi channels, and supports 5 simultaneous systems;

-- The microphone features an aluminum alloy boom with a built-in 2 x 14mm high-fidelity gold-plated condenser capsule and supports dual-capsule lateral array technology.

-- The boom incorporates 32,500 high-density acoustic interference holes with a diameter of 0.4mm. The apertures are precisely calculated for diameter and spacing, and interference correction technology is used to precisely control pickup details, effectively enhancing sensitivity across the vocal frequency range.

-- The high-sensitivity design and built-in automatic gain function ensure an effective pickup distance of 60-100cm.

-- The microphone unit features independent gain adjustment from 0 to 10 levels, allowing for customized adjustment of the boom gain.

-- High-fidelity lossless audio transmission technology, 48kHz audio sampling frequency, and a frequency response of 20Hz-20kHz;
-- It adopts forward error correction and retransmission mechanism, has super anti-interference ability, can effectively isolate the interference of mobile phones, radio waves, Bluetooth, WiFi and other signals, and will not generate noise when there is an incoming call;

-- A single host supports up to 999 wireless conference units online, including support for connection to a chairperson unit, which has priority.

-- 4 conference modes: First-in-First-Out, Free Discussion, Chairperson's Permission, and Voice-activated Start. The number of wireless speakers can be set from 1 to 4.

--  Combined with an HD camera, it enables automatic speaker tracking and image switching, supports image freezing, and allows multiple cameras to track the same conference unit.

-- Built-in 3000mA/H high-capacity lithium battery with dual charging capabilities, supporting both USB charging and charging in the charging box.
