Product Overview

Professional 8-Element AES67 Network Microphone Array

The SNA-08A 8-Element AES67 Omnidirectional Network Microphone Array is designed for professional indoor conferencing, education, lecture recording, AI classrooms, remote teaching and intelligent audio applications.

Featuring an 8-MEMS microphone array and SISTC’s BATSound-SRAF™ adaptive array algorithm, the microphone automatically tracks the active speaker and enhances voice clarity while suppressing unwanted ambient noise and room reverberation.

With up to 60 m² pickup coverage, built-in AEC, noise reduction, automatic gain control and reverberation suppression, the SNA-08A delivers clear and natural voice capture for demanding indoor acoustic environments.

The microphone supports AES67 1×1 network audio and USB Audio Class (UAC), with flexible 12 V DC, USB 5 V and standard 48 V PoE power options. This allows the device to integrate easily into professional network audio, conferencing and AV systems.

Key Features

8-MEMS Omnidirectional Microphone Array

An 8-element MEMS microphone array provides wide-area voice capture for indoor meeting and teaching environments.

Up to 60 m² Pickup Coverage

Designed for medium-sized indoor spaces, the microphone provides wide-area voice pickup without requiring participants to stay close to the microphone.

BATSound-SRAF™ Adaptive Array Algorithm

The proprietary array processing algorithm enables adaptive beam tracking and voice enhancement, helping maintain clear and natural speech output as the active speaker changes position.

AI Noise Reduction

Advanced audio processing suppresses steady-state background noise while preserving speech clarity.

Adaptive Reverberation Suppression

Designed for rooms with reflections and reverberation, the algorithm improves speech intelligibility in challenging acoustic environments.

Built-in AEC

Acoustic Echo Cancellation enables the microphone to work with active speakers and supports full-duplex remote communication.

AES67 + USB Audio

Supports AES67 1×1 network audio and USB Audio Class (UAC) for flexible integration with professional network audio and USB audio systems.

PoE / DC / USB Power

Supports:

• Standard 48 V PoE
• DC 12 V
• USB 5 V

This provides flexible deployment options for different system architectures.

Multiple Installation Options

The compact microphone can be installed using:

• Ceiling mount
• Pendant / suspension mount
• Wall mount

Audio Processing

The SNA-08A integrates multiple audio processing technologies to improve voice quality in real-world indoor environments.

Audio Processing Functions

• Steady-state noise reduction
• Automatic Gain Control (AGC)
• Acoustic Echo Cancellation (AEC)
• Reverberation suppression
• Adaptive beamforming
• Speaker tracking
• Voice enhancement

The combination of microphone array processing and acoustic algorithms helps provide consistent speech capture even when speakers move around the room.

Network Audio Connectivity

AES67 Network Audio for Professional AV Systems

The SNA-08A supports AES67 1×1 network audio, allowing the microphone to connect directly to compatible IP-based audio systems.

This makes it suitable for applications where audio needs to be transported over an Ethernet network rather than through conventional analog microphone cabling.

Network Interface

• LAN × 1
• AES67 1×1
• USB Audio Class
• Standard PoE 48 V

The network audio output can also be used as a source for applications such as speech transcription, recording, remote teaching and AI-powered audio processing.

Flexible System Integration

The SNA-08A supports up to 1+1 cascading configuration, providing additional flexibility when multiple audio devices are deployed within the same system.
