Product Overview

32-Element AES67 AI Network Microphone Array

The SNA-32A-G1 32-Element AES67 AI Network Microphone Array is a professional network microphone designed for large conference rooms, training rooms and modern IP-based audio applications.

The microphone integrates a 32-MEMS microphone array with SISTC’s proprietary 5A acoustic algorithm platform, providing advanced audio processing for clear and natural far-field voice capture.

With up to 100 m² pickup coverage, the SNA-32A-G1 supports AI transient noise reduction, automatic gain control, acoustic echo cancellation, reverberation suppression and adaptive beam tracking to improve speech intelligibility in challenging indoor environments.

The microphone supports AES67 2×2 network audio and USB Audio Class, with two independent Ethernet interfaces and standard 48 V PoE for flexible professional network deployment.

The SNA-32A-G1 also supports simultaneous network, USB and analog Line Out audio, allowing it to integrate with different conferencing, AV, DSP and recording systems.

Key Features

32-MEMS Microphone Array

A 32-element MEMS microphone array provides high-density spatial audio acquisition for large meeting rooms and professional audio environments.

Up to 100 m² Pickup Coverage

The SNA-32A-G1 is designed for wide-area voice capture with up to 100 m² pickup coverage, depending on room acoustics, installation height and environmental conditions.

AI 5A Acoustic Algorithm

The integrated AI computing platform supports SISTC’s proprietary 5A acoustic algorithm, combining multiple audio processing technologies for enhanced voice clarity.

Audio processing includes:

• AI transient noise reduction
• Automatic Gain Control (AGC)
• Acoustic Echo Cancellation (AEC)
• Reverberation suppression
• Adaptive beam tracking
• Voice enhancement

Adaptive Beam Tracking

The microphone automatically tracks the active speaker and enhances the corresponding voice signal.

For ceiling-mounted installations, the beam tracking elevation range can be configured according to the installation environment.

AES67 2×2 Network Audio

The SNA-32A-G1 supports AES67 2×2 network audio, enabling direct integration with professional IP-based audio systems.

Dual Independent Ethernet

Two independent LAN interfaces provide flexible network connectivity for professional audio deployments.

Standard 48 V PoE

Standard PoE provides both power and network connectivity through Ethernet, helping simplify installation and reduce cabling requirements.

Simultaneous Audio Output

The microphone supports multiple audio interfaces:

• AES67 network audio
• USB Audio Class
• Analog Line Out

This allows flexible integration with network audio systems, computers, DSPs and conventional audio equipment.
