Description

The COM-MIC-HUB is a compact microphone hub designed to centralize and optimize audio capture for classrooms and conference rooms. It combines a professional audio DSP with flexible I/O to improve both local and remote audio clarity. The unit supports wired ceiling microphones and a wireless microphone input via a balanced Phoenix connector.

Key audio processing features include acoustic echo cancellation, background noise reduction, and automatic gain control to maintain consistent speech levels. The built-in DSP processes signals for both room loudspeakers and remote conferencing. An independent Line Out provides a dedicated feed to external amplifiers or speakers for wider coverage.

Physical connectivity includes a USB-B host port, an RJ45 port for ceiling mic connectivity, a 3-pin Phoenix balanced wireless mic input, and 5-pin Phoenix connectors for AEC reference and AEC output. Control connectivity is provided via Ethernet for the Web-UI and a 3-pin Phoenix RS-232 port that supports Telnet commands. Trigger inputs and outputs support simple contact closure or voltage-based alarm integrations.

The device is managed through an intuitive Web-UI that exposes routing, mixing and level control, and it also supports RS-232 integration into centralized AV control systems. Firmware updates are available via the Web-UI or SSH to keep system software current. Network control and matrix-style routing make it straightforward to integrate into existing AV networks.

This microphone hub is suited to lecture capture, conferencing, and distance-learning scenarios where clear speech intelligibility and echo-free calls are required. It helps ensure remote participants hear the room naturally while maintaining stable local reinforcement. The independent line-level output lets integrators drive room amplification without altering processed feeds sent to remote endpoints.

The COM-MIC-HUB is engineered for rack or surface mounting in AV furniture and cabinets and is compact enough for discreet installation near signal sources. Operating temperature and storage ranges accommodate standard AV environments. The Web-UI and RS-232 control reduce commissioning time and simplify routine adjustments for IT and AV teams.
