Product Description
M20 Dual Channel Service Counter Microphone Module
At a busy counter, operators and customers speak across a divide. The M20 uses a dual channel directional array to separate A/B speakers while suppressing off-angle voice leakage by ≥12dB SPL, protecting private conversations.
Counter-Facing Strengths
- Service Counter A/B Separation: left/right pickup lobes keep two talkers distinct.
- ≥12dB SPL Off-Angle Suppression: blocks nearby queue conversations for privacy.
- Dual Output Interfaces: USB Type-C and 3.5mm analog audio, driver-free.
- OEM/ODM Acoustic Tuning: cable, connector and firmware customization available.
