Product Description
M20 Directional Pickup Microphone Array Module
Where clear voice capture matters, the M20 directional pickup array module combines a 60° bidirectional directivity pattern with a 65dB(A) signal-to-noise ratio. The onboard DSP suppresses ambient noise by more than 20dB, keeping speech intelligible even in busy public terminals.
Why Choose the M20 Array
- 60° Bidirectional Directivity: two tight pickup lobes reject side and rear noise sources.
- 65dB(A) SNR, -26±1dB Sensitivity: clean, low-noise 16kHz/48kHz 16bit capture.
- ≥20dB Noise Reduction + ≥12dB Off-Angle Suppression: DSP keeps only the target talker.
- USB Audio Class 1.0: driver-free plug-and-play for Windows, Linux and Android hosts.
