Product Overview

8-Element AES67 Network Microphone Array for Flexible Audio Deployment

The SNA-08A-G1 8-Element AES67 Network Microphone Array is a versatile professional audio capture solution designed for conferencing, education, lecture recording, AI classrooms, classroom supervision and intelligent audio applications.

Featuring an 8-MEMS microphone array and up to 80 m² pickup coverage, the SNA-08A-G1 provides wide-area voice capture while supporting flexible installation on desks, ceilings or walls.

Its digital audio architecture supports simultaneous multi-stream audio output, including AES67 network audio, USB digital audio and analog audio, allowing the microphone to integrate with a wide range of professional AV and audio systems.

The network audio stream can simultaneously provide far-field omnidirectional audio for applications such as remote teaching, lecture recording, speech transcription and AI-powered audio processing.

For ceiling-mounted applications, the adaptive beam tracking function can be configured according to the required elevation angle, helping focus voice enhancement toward the active speaker.

Key Features

8-MEMS Microphone Array

An 8-element MEMS microphone array provides wide-area voice acquisition for meeting rooms, classrooms and other indoor environments.

Up to 80 m² Pickup Coverage

The SNA-08A-G1 is designed for large-area voice capture, supporting up to 80 m² pickup coverage, depending on room acoustics and deployment conditions.

Multi-Stream Audio Output

The digital audio architecture allows multiple audio outputs to work simultaneously, supporting:

• AES67 network audio
• USB digital audio
• Analog audio

This provides greater flexibility when integrating the microphone into different audio systems.

AES67 Network Audio

The built-in Ethernet interface supports AES67 1×1 network audio, allowing the microphone to operate as a network audio endpoint within professional IP audio systems.

HTTP / RTSP / AES67 Audio Streaming

The network architecture supports multiple network audio streaming methods, including:

HTTP / RTSP / AES67

This enables flexible integration with network-based recording, streaming, monitoring and audio processing systems.

Adaptive Beam Tracking

The microphone can track the active speaker and enhance the corresponding voice signal.

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

Built-in Acoustic Processing

The SNA-08A-G1 integrates:

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

These functions help improve speech intelligibility in real-world indoor environments.

Flexible Installation

The product supports:

• Desktop installation
• Ceiling mounting
• Wall mounting

This allows the same platform to be deployed across different room layouts.

Standard PoE

The SNA-08A-G1 supports standard 48 V PoE power, simplifying installation by allowing power and network connectivity to share a single Ethernet cable.

Multi-Interface Audio Architecture

One Microphone Array, Multiple Audio Outputs

One of the major advantages of the SNA-08A-G1 is its flexible audio architecture.

The device can provide audio through multiple interfaces:

Network Audio

AES67 1×1

Suitable for professional IP audio systems and network-based audio processing.

USB Audio

USB 2.0

Suitable for computers, teaching systems, conferencing systems and AI audio applications.

Analog Audio

Line In ×2 / Line Out ×1

Provides direct integration with conventional analog audio equipment.

This combination makes the SNA-08A-G1 suitable for both traditional AV systems and modern network audio architectures.

Network Audio Streaming

AES67, HTTP and RTSP Connectivity

The SNA-08A-G1 is designed for network-based audio acquisition and supports multiple network audio streaming architectures.

The network audio stream can be used for:

• Remote teaching
• Lecture recording
• Speech transcription
• Audio monitoring
• AI speech recognition
• Network audio processing
• Remote conferencing

For educational applications, the far-field audio stream can be transmitted through the network while maintaining compatibility with existing IP-based audio and teaching infrastructure.
