Erthpot NCS-5C Chairman Unit for Novo Conference System

The Command Center for Structured Discussions

In high-level corporate and government environments, a conference system is only as effective as its management capabilities. The Erthpot NCS-5C chairman unit acts as the authoritative terminal within the Novo ecosystem. While delegate units allow for participation, the chairman unit introduces a layer of governance necessary for maintaining order. Through a dedicated priority button, the moderator can suppress other active microphones, ensuring that critical announcements or concluding remarks are heard without interruption. This hardware-level hierarchy is fundamental for legislative assemblies and executive boardrooms.

The system utilizes a wired digital architecture, connecting via standard CAT5 cabling to the NCS110-CU central controller. This ensures a stable, interference-free audio path that far exceeds the reliability of wireless alternatives. By integrating the chairman unit into the system, AV consultants can provide clients with a “plug-and-play” solution that manages participant speaking turns automatically while reserving ultimate control for the session leader.

Mission-Critical Features for Professional Environments

• Integrated Priority Override Button
  The standout feature of the NCS-5C is its ability to take command of the meeting. With a single press, the chairman can mute all active delegate microphones, effectively clearing the audio floor for important interventions.
• Shotgun-Style Gooseneck Microphone
  The unit is equipped with a flexible gooseneck that utilizes a cardioid pickup pattern. This design prioritizes the speaker’s voice while rejecting ambient room noise and acoustic reflections, ensuring absolute clarity.
• High-Vis LED Status Ring
  To prevent confusion during lively discussions, a bright LED ring at the base of the capsule illuminates to show the “active” or “mute” status. This provides instant visual feedback to both the speaker and the audience.
• Premium Die-Cast Construction
  The chassis is manufactured from a high-quality aluminum alloy. This provides the physical weight required for stability on the conference table and the durability needed for daily enterprise use.

Operational Dynamics and Signal Intelligence

The NCS-5C functions as an intelligent node on the Novo network. When the priority button is engaged, the unit sends a high-priority data packet to the NCS110-CU controller. The controller instantly processes this request, overriding the current microphone queue and deactivating all delegate units. This logic is handled at the hardware level, ensuring near-zero latency in meeting control. Because the unit is powered directly by the 24V DC line from the controller via CAT5, there is no need for local power outlets or batteries, simplifying the aesthetic of the boardroom table.

The signal flow follows a “digital-over-wired” path. The analog voice captured by the cardioid capsule is optimized through the system’s automatic gain processing. This technology prevents sudden feedback spikes and levels the audio, so every participant is heard at a consistent volume, regardless of their distance from the microphone.

Advanced Acoustic Engineering

For conference applications, the cardioid pickup pattern is essential. By focusing the sensitivity on the front of the microphone, the NCS-5C avoids picking up the sound of papers rustling or background HVAC noise. With a wide frequency response of 50Hz to 20kHz, the unit captures the full natural range of human speech, which is critical for reducing listener fatigue during long sessions. A signal-to-noise ratio of over 100dBA ensures that the audio output is pristine, making it ideal for high-quality recording or broadcast feeds.

Seamless Infrastructure Integration

The NCS-5C is designed to work in harmony with the broader AV ecosystem. Through the central controller, the chairman unit triggers automated camera tracking. When the chairman speaks, the system can command a PTZ camera to move to the chairman’s preset location via RS232 or RS422 protocols. Furthermore, the audio can be routed through the controller’s Dante interface to a larger room DSP or streaming system, making the chairman unit the primary point of origin for professional audio networking.

Technical Specifications

Ideal Environments for Deployment

The NCS-5C is engineered for venues that require managed, professional discussion:

• Executive Boardrooms: Provides the CEO or Chairman with physical tools to moderate high-level strategy sessions.
• Legislative Chambers: Essential for council leaders to manage debate and ensure orderly proceedings.
• University Lecture Halls: Allows professors to override student discussion units for lecture-based segments.
• Crisis Management Centers: Facilitates clear communication where a lead coordinator must direct the conversation.

System Installation and Wiring Standards

Deploying the NCS-5C is straightforward for AV integrators. The unit utilizes a daisy-chain architecture, meaning units are connected in series using standard CAT5 or CAT6 network cables. The “Hand-in-Hand” connection method significantly reduces installation time and cabling costs. For optimal performance, it is recommended to place the chairman unit at the start of the chain or in a position easily accessible to the moderator. Once connected to the NCS110-CU, the system auto-detects the unit, requiring no manual addressing for standard operation.

Chairman vs. Delegate: Key Functional Differences

System Scalability and Compatibility

To ensure maximum performance, the NCS-5C should be used with the following Novo ecosystem components:

• NCS110-CU Controller: The master unit for processing audio, power, and camera tracking.
• NCS-5D Delegate Units: Participatory units for meeting delegates.
• Flush Mount Units: Architectural options for permanent, recessed installation.
• NEB-124W Extension Box: Provides additional power to support up to 110 microphone units.
