3 核高清数字智能降噪拾音器 ,是我司专为银行、证券金融、电力、税务、通信服务商、交易中心、政务中心、学校、医院、标准化考场、售票或收银服务性窗口等重要需拾音录音的环境而设计。 3- core high-definition digital intelligent noise reduction pickup , which is an important requirement of our company for banking, securities finance, electricity, taxation, communication service providers, trading centers, government centers, schools, hospitals, standardized test rooms, ticket sales or cashier service windows Designed for the environment of pickup recording.

3 核高速数字信号处理器,自适应动态降噪处理技术,多层电路设计,内置降噪功能,无需增加外部降噪设备。 Built-in 3- core high-speed digital signal processor, adaptive dynamic noise reduction processing technology, multilayer circuit design, built-in noise reduction function, no need to add external noise reduction equipment.

AGC 高保真纯数字降噪处理,能使声音捕捉全面,信号输出洁净清晰,无“吱吱吱”电子噪声。 AGC high-fidelity pure digital noise reduction processing, can make the sound capture comprehensive, the signal output is clean and clear, no "squeak" electronic noise.

Built-in anti-howling notch processing, anti-echo and anti-howling circuit design, so that the product is always gentle and stable, like a rock.

The anti-interference circuit is designed to perform differently in complex environments, and it can also transmit live sound stably and clearly.

High-sensitivity omnidirectional condenser microphone with omnidirectional pickup and high sound reduction.

DSP 动态处理,精准做到环境有声源时“喧哗你的喧哗”,无声源时“安静你的安静”。 DSP dynamic processing, accurately "noisy your noise" when there is a sound source in the environment, "quiet your quietness" when there is no sound source.

Built-in intelligent noise reduction analysis pure digital circuit, sensitive human voice effect.

Digital processing technology of audio source to effectively isolate electronic noise. When the monitoring sensitivity is amplified, the noise will not be amplified linearly with it, thereby doubling the effective monitoring area.

DC 9-14V ),可与前端摄像机, POE 等设备轻松搭配。 Low power consumption and wide voltage working circuit design ( DC 9-14V ), can be easily matched with front-end cameras, POE and other equipment. High compatibility and integration.

Disc-shaped appearance, surface light wave process treatment, fashionable, beautiful and high-grade. Double-layer metal paint mesh cover design, durable and never fade and paint;

The tongue-and-groove design of the slider structure is easy to install, and it is handy for flat desktop or ceiling and side wall installation.

Built-in lightning protection, power supply overload protection, reverse polarity protection of power supply, electrostatic protection. Safety and reliability have been greatly improved.

High-quality shielded three-core audio leads, tin-tipped handle, effective and stable contact and transmission performance.
