Description
M20 adopts a 2-microphone array design with a fixed 60° forward pickup angle, with valid sound pickup within 3 meters. Sound shielding zones block noise from sides and rear areas. The microphone only collects front human voice and rejects surrounding clutter, avoiding messy audio caused by wide-range sound reception. It fits fixed desktop conversation scenarios perfectly.
6 Core Functional Advantages of 2-Array Directional Microphone M20
1. Dual Microphone Array + 60° Targeted Directional Pickup
2. A/B Independent Voice Separation Technology
The core role separation algorithm divides audio into two independent vocal tracks. Voices of two speakers are separated clearly with zero crosstalk between zones. It greatly improves accuracy for voice-to-text conversion and real-time AI translation, making the M20-Single the preferred mic for bank counters, hotel front desks, law interviews and bilingual receptions.
3. Powerful Background Noise Suppression
Built-in digital noise reduction module automatically suppresses daily interfering sounds including air-conditioning hum, keyboard clicks, crowd murmurs and office echoes. Human voice details are fully retained without distortion, enabling clear voice capture even in busy public areas such as service halls and shopping malls.
4. Adjustable Pickup Gain & One-Click Mute Control
A durable multifunctional metal knob is reserved on the base. Users can manually adjust pickup sensitivity to match different speaking distances. Short press for instant mute; press again to resume recording. The status indicator light displays mute/working state in real time for intuitive operation.
5. Bendable Metal Gooseneck for Flexible Positioning
The deformable metal gooseneck hose supports arbitrary bending and angle locking. Users freely adjust the height and pointing direction of the microphone head to align with the speaker’s mouth, adapting to different desk heights, sitting postures and placement layouts.
6. USB Type-C Universal Plug-and-Play
Standard Type-C wired connection offers broad compatibility with Windows, tablets, translation machines and conference all-in-one devices. No driver installation required; plug in and start recording immediately. An extra audio output interface is reserved for flexible audio signal transmission.
