Product Overview

The SNA-32A-G1 is a professional 32-element AES67 network conference microphone array designed for high-quality speech capture in conference rooms, training rooms and other professional AV environments.

Featuring 32 high-performance MEMS microphones and SISTC’s 5A Acoustic Algorithm, the microphone array combines AI transient noise reduction, automatic gain control (AGC), acoustic echo cancellation (AEC), reverberation suppression and intelligent beam tracking to deliver clear and natural speech across spaces of up to 100 m².

An advanced AI acoustic processing platform with an octa-core processor and up to 6 TOPS of AI computing performance provides a powerful processing foundation for advanced acoustic algorithms, AI model development and application-specific customization.

The SNA-32A-G1 supports AES67 2×2 network audio, USB Audio Class and dual independent Ethernet interfaces. Multiple microphone arrays can also be cascaded to extend audio coverage for larger rooms and distributed conference systems.

With flexible installation options including pendant, ceiling and recessed ceiling mounting, the SNA-32A-G1 provides a scalable solution for modern IP-based professional audio systems.

Key Features

32-Element MEMS Microphone Array

The 32-element MEMS microphone array provides high-density acoustic sampling for accurate sound capture and speaker localization.

It is optimized for professional speech pickup in conference and training environments with coverage of up to 100 m², depending on room acoustics and installation conditions.

AI Transient Noise Reduction – Level 2

The integrated AI transient noise reduction algorithm helps suppress sudden environmental noises while preserving speech clarity and natural voice characteristics.

This makes the SNA-32A-G1 suitable for meeting spaces where keyboards, doors, paper movement and other transient noises may affect speech quality.

SISTC 5A Acoustic Algorithm

The SNA-32A-G1 integrates SISTC’s 5A Acoustic Algorithm, combining multiple audio processing technologies into a unified acoustic processing system.

Key functions include:

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

The combination is designed to provide stable and consistent speech quality across different room environments.

Intelligent Beam Tracking

The microphone array dynamically tracks the active speaker according to their position.

The beam tracking algorithm continuously adjusts the pickup direction, helping maintain consistent voice capture when speakers move around the meeting room.

AES67 Network Audio

The SNA-32A-G1 supports AES67 2×2 network audio, providing a professional IP-based audio interface for integration with compatible network audio systems.

AES67 enables audio to be transported over standard IP networks, making the microphone array suitable for distributed AV and professional network audio deployments.

Multi-Microphone Cascading

Multiple SNA-32A-G1 units can work together as a distributed microphone system.

The intelligent mixing system can coordinate audio pickup according to speaker position and combine audio from multiple microphone arrays.

This allows system coverage to be expanded for larger conference rooms, training rooms and other spaces requiring multiple microphone units.

AI Acoustic Processing Platform

The SNA-32A-G1 is built around a high-performance processing platform featuring an octa-core processor and up to 6 TOPS of AI computing performance.

The platform provides processing resources for advanced acoustic algorithms, AI model development and application-specific customization.

This architecture also provides flexibility for future algorithm updates and customized audio applications.

Flexible Audio Interfaces

The microphone array supports multiple audio output interfaces for flexible system integration:

AES67 Network Audio + USB Audio + Analog Audio

This allows the SNA-32A-G1 to be integrated into professional AV systems, computers, conferencing platforms and external audio equipment.

PoE and DC Power

The SNA-32A-G1 supports:

• Standard PoE 48V
• DC 12V

PoE enables both power and network connectivity through a single Ethernet connection, helping simplify installation in professional AV environments.

Intelligent Multi-Microphone Collaboration

For larger rooms, multiple microphone arrays can be deployed together.

The SNA-32A-G1 supports 1+2 cascading architecture, allowing multiple units to cooperate within a distributed microphone system.

According to the active speaker’s position, the system can coordinate microphone pickup and perform intelligent mixing across cascaded units.

This architecture is particularly useful for:

• Large conference rooms
• Training rooms
• Boardrooms
• Multi-zone meeting spaces
• Professional AV installations

Installation

The SNA-32A-G1 supports multiple installation configurations:

• Pendant mounting
• Ceiling mounting
• Recessed ceiling installation

The ceiling-mounted configuration is particularly suitable for rooms requiring unobtrusive microphone installation and wide-area speech pickup.
