The CS-310M is a high-end Central Controller (often referred to as a “Monitor” or “Host”) for the CS series professional conference discussion systems. It represents an upgrade over entry-level controllers by adding advanced visual feedback and network management features.
Core Functionality
The “M” in the model name typically stands for Main or Master unit. In this system, it acts as the power supply and signal processor for all connected microphone units.
- Integrated Display: Unlike simpler units, the CS-310M features a high-definition screen (often OLED or LCD) that allows the chairman or technician to monitor the conference status, including active speaker IDs and battery/signal levels for wireless units.
- System Capacity: A single CS-310M can typically power and manage up to 60 microphone units directly, with expansion capabilities to handle over 250 units via extension power supplies (like the EXP-124).
- Operating Modes:
- FIFO: Standard first-in-first-out rotation.
- Request Mode: The chairman must manually approve delegate requests through the monitor interface.
- Timed Speech: Limits each speaker to a pre-set duration.

Chairman Monitoring Features
When used as a “Chairman Monitor,” this unit allows for:
- Visual Queue Management: Seeing exactly who is waiting in line to speak on the screen.
