4-Mic Array with Integrated Speaker Amplifier – 60° Directional Beamforming – Split-Type Module – GYKY-4M-A60-S

4-Mic Array with Integrated Speaker Amplifier – 60° Directional Beamforming – Split-Type Module – GYKY-4M-A60-S

Product Overview

The GYKY-4M-A60-S is a professional-grade 4-Channel Linear MEMS Microphone Array engineered for precision directional voice capture and intelligent audio processing.

Featuring a sophisticated 60° Directional Beamforming architecture, this module acts as a “voice spotlight,” isolating the target speaker while aggressively suppressing ambient noise and off-axis interference. It comes fully integrated with a high-performance Acoustic Suite, including advanced Echo Cancellation (AEC), Noise Suppression, and Automatic Gain Control (AGC).

Designed for seamless integration, the AMM-DP60-4 features a USB interface for plug-and-play connectivity and an onboard speaker amplifier, providing a complete audio input/output loopback. It is the definitive solution for high-clarity Human–Machine Interaction (HMI), smart digital signage, conference terminals, and interactive display systems.

Key Features

  • Precision 60° Directional Pickup: Linear 4-mic beamforming effectively isolates target voice while suppressing surrounding noise.

  • Instant Local Wake-Word Engine: Optimized for fast, reliable voice activation with low-latency response.

  • Integrated Dual 5W Amplifier: Supports Dual 4Ω 5W speaker output, providing a complete audio solution without external amp boards.

  • USB UAC 1.0 & Camera HUB Support: Plug-and-play compatibility with Windows, Android, and Linux; ideal for video conferencing integration.

  • Advanced Acoustic Suite:

    • AEC (Echo Cancellation): Full-duplex communication even during high-volume playback.

    • BF & DPUS: Precision directional pickup and sound source isolation.

    • NS & AGC: Noise suppression (≥20dB) and automatic gain for consistent audio levels.

  • Ultra-Slim Design: 160mm x 6mm mic board, perfect for integration into smart displays and slim bezels.
