Product Overview
The SNA-32D-G1 is a professional 32-element Dante network conference microphone array designed for high-quality speech capture in conference rooms, training rooms and professional AV environments.
The microphone array integrates 32 high-performance MEMS microphones with SISTC’s 5A Acoustic Algorithm, combining AI transient noise reduction, automatic gain control, acoustic echo cancellation, reverberation suppression and intelligent beam tracking.
With pickup coverage of up to 100 m², the SNA-32D-G1 is designed to provide clear and stable speech capture across medium and large meeting spaces.
An advanced AI acoustic processing platform powered by an octa-core processor and up to 6 TOPS of AI computing performance provides the processing capability required for advanced acoustic algorithms, AI model development and application-specific customization.
The SNA-32D-G1 supports Dante 2×2 network audio, USB Audio Class and dual independent Ethernet interfaces. Multiple units can be cascaded to create a distributed microphone system for larger rooms.
Key Features
32-Element MEMS Array
The 32-element MEMS microphone array provides high-density acoustic sampling for precise sound capture and speaker localization.
With up to 100 m² pickup coverage, the SNA-32D-G1 is suitable for conference rooms, training rooms and professional AV installations.
AI Transient Noise Reduction – L2
The integrated AI transient noise reduction system helps reduce sudden environmental noises while maintaining speech intelligibility.
It is designed to improve the overall listening experience in real-world conference environments.
5A Acoustic Algorithm
SISTC’s 5A Acoustic Algorithm combines several core acoustic processing functions:
- AI transient noise reduction
- Automatic Gain Control
- Acoustic Echo Cancellation
- Reverberation suppression
- Intelligent beam tracking
The integrated processing architecture helps provide stable speech quality across different room conditions.
Intelligent Beam Tracking
The microphone array automatically detects and tracks the active speaker.
As the speaker changes position, the beam tracking algorithm dynamically adjusts the pickup direction to maintain consistent voice capture.
Dante Network Audio
The SNA-32D-G1 supports Dante 2×2 network audio, allowing it to integrate into professional Dante-based audio and AV systems.
Dante networking simplifies the distribution of digital audio across IP networks and provides a flexible architecture for professional conferencing, commercial AV and networked audio applications.
Multi-Microphone Cascading
The SNA-32D-G1 supports 1+2 cascading, allowing multiple microphone arrays to cooperate as a distributed audio pickup system.
The system can coordinate microphone pickup and perform intelligent mixing according to the active speaker’s position.
This provides a scalable architecture for larger conference rooms and training spaces.
AI Acoustic Processing Platform
The SNA-32D-G1 integrates an octa-core processor with up to 6 TOPS of AI computing performance.
This provides a powerful platform for:
- AI acoustic processing
- Noise reduction
- Beam tracking
- Voice enhancement
- AI model development
- Application-specific customization
The architecture also provides a foundation for future algorithm upgrades.
Multi-Interface Audio Output
The SNA-32D-G1 supports flexible audio connectivity through:
Dante Network Audio + USB Audio + Analog Audio
This enables integration with:
- Dante audio networks
- Conference systems
- Computers
- DSP processors
- External audio equipment
PoE Connectivity
The microphone supports standard 48V PoE, allowing power and network connectivity to be carried over Ethernet.
It also supports DC 12V power for installations where PoE is not available.
Professional Dante Audio Architecture
The SNA-32D-G1 is designed for professional Dante network audio systems.

This architecture allows the microphone array to become part of a larger networked audio infrastructure.
Intelligent Multi-Microphone System
For larger conference spaces, multiple SNA-32D-G1 units can be deployed as a coordinated microphone system.
The 1+2 cascading architecture enables multiple units to cooperate while the intelligent mixing system coordinates audio according to speaker position.
This makes the system suitable for applications where a single microphone array cannot provide sufficient coverage.
Installation
The SNA-32D-G1 supports:
- Pendant installation
- Ceiling installation
- Recessed ceiling installation
The ceiling-oriented design helps maintain a clean installation appearance while providing wide-area speech pickup.
