Capture the room without crowding the table
Coverage that scales with the room
Each unit has a published 3-metre pickup distance. Up to six microphones can be cascaded over PoE network cable for distributed room coverage.
AI-enhanced voice processing
Blind beamforming helps locate the sound source, while noise suppression, gain control, and echo cancellation support clearer conference audio.
Digital, network, and analog connections
Use USB Type-C for UAC audio and configuration, RJ45 for cascading, and AUX1/AUX2 for compatible line-level audio workflows.

Check the room fit
Plan pickup as part of the complete audio system
NCG can assess microphone quantity, positions, cable paths, PoE topology, USB host connection, room acoustics, and the separate loudspeaker design.
- Table layout supports tabletop microphones
- Each unit's 3m pickup area is mapped to seating
- Cascade quantity is selected for the room
- PoE and cable paths are planned before installation
- USB or line-level audio fits the conferencing system
- Speakers and cameras are specified separately
