Product Details (Specifications)
1. Advanced Acoustic Performance
4-Channel MEMS Array: Equipped with four high-performance digital MEMS microphones for superior sensitivity and SNR
180° Directional Pickup: Precise beamforming technology captures sound in a 180° forward arc while effectively shielding background noise and voices outside the target zone.
Professional Audio Processing: Integrated algorithms for Echo Cancellation (AEC), Noise Suppression (ANS), Automatic Gain Control (AGC), and Speech Enhancement.
Long-Distance Capture: Optimized for high-fidelity pickup at distances of 3 to 10 meters.
2. Flexible Modular Hardware
Split-Type Design: Features a dedicated mainboard (100mm x 20mm) and a slim microphone strip board (115mm x 6mm), allowing for versatile placement within your product’s chassis.
Customizable Camera: The system supports various camera sensor options (up to 13MP/4K) to meet specific imaging requirements.
Integrated USB Hub: The mainboard supports a HUB function to seamlessly connect and power camera devices via a single USB interface.
Amplifier Support: Includes support for speaker amplifier output (4Ω 2.5W) for a complete two-way audio solution.

5. Installation & Design Recommendations
To ensure optimal acoustic performance, we recommend:
Sealing: Use the provided rubber gaskets to seal the microphone pickup hole, preventing internal structural reverberation.
Isolation: The module is designed to be shock-proof; however, maintain sufficient distance between the speakers and microphones to prevent vibration interference.
