Erthpot NCS-5D Delegate Unit for Novo Conference System

The Backbone of Collaborative Discussion

In a professional conference environment, the delegate unit serves as the primary interface between the participant and the audio ecosystem. The Erthpot NCS-5D is not merely a microphone; it is a sophisticated terminal that digitizes and manages local speech within a networked system. By connecting directly to the NCS110-CU central controller, the NCS-5D becomes part of a managed audio grid, allowing for structured discussion modes such as FIFO or voice-activation. The use of a wired architecture eliminates the interference and latency issues often associated with wireless alternatives, providing a “bulletproof” signal chain for enterprise users.

The integration of cardioid polar patterns is a deliberate choice for modern meeting rooms. By focusing sensitivity on the speaker and rejecting ambient noise from the rear of the capsule, the NCS-5D significantly reduces the risk of acoustic feedback. This directional pickup ensures that even in rooms with challenging acoustics or high ceiling reflections, the resulting audio remains crisp and intelligible for both local reinforcement and remote participants.

Engineered for Clarity and Control

The NCS-5D incorporates several high-performance features designed to enhance the user experience and simplify system management:

• Integrated Shotgun Gooseneck
  The unit features a precision-engineered gooseneck that allows for flexible positioning. The shotgun-style design provides a focused pickup area, ensuring that the speaker’s voice is captured with high sensitivity while minimizing background noise.
• Dual-Status LED Indicator
  A visual illuminating ring at the base of the microphone provides instant status feedback. A green light indicates an active speaking status, while a red light signals that the unit is muted, allowing participants and chairmen to see system status at a glance.
• Aluminum Alloy Die-Cast Chassis
  Unlike plastic-heavy alternatives, the NCS-5D is built with a heavy-duty aluminum alloy body. This provides superior RF shielding, excellent thermal management, and the physical weight necessary to remain stable on high-end boardroom tables.
• Loop-Through CAT5 Architecture
  By utilizing standard RJ45 connectors and CAT5/6 cabling, the NCS-5D simplifies the installation process. This “loop through” method allows for rapid daisy-chaining of units, reducing the total amount of cable required for large installations.

Operational Architecture and Signal Flow

The NCS-5D operates as a peripheral to the NCS110-CU Central Control Unit. When a participant presses the built-in mute/talk button, a control signal is sent via the CAT5 network to the controller. The controller then validates the request based on the active conference mode (such as FIFO or Request mode) and activates the microphone capsule. Once active, the analog audio is converted and routed through the controller’s gain processing stage, eventually reaching the Dante or analog outputs.

This system design allows for massive scalability. While the central controller manages the logic and power, the system can be expanded to support up to 110 units by adding NEB-124W extension boxes. Each delegate unit draws only 0.72W of power, ensuring that even large-scale deployments remain energy-efficient and thermally stable.

Advanced Microphone Technology

The core of the NCS-5D is its cardioid condenser capsule. This technology is preferred in conferencing because of its directional sensitivity. With a frequency response of 50Hz to 20KHz, the unit covers the full spectrum of human speech, ensuring that both deep baritone and higher-pitched voices are reproduced naturally. A signal-to-noise ratio of >100dBA ensures that the “noise floor” remains virtually silent, which is vital when multiple microphones are active simultaneously in a large system.

Technical Specifications

Deployment Scenarios

The NCS-5D is a versatile unit capable of professional performance in several environments:

• Corporate Boardrooms: Provides a clean, aesthetic look with high-fidelity pickup for critical executive decisions.
• Government Council Halls: Supports large-scale daisy-chaining for numerous participants in legislative sessions.
• Training Centers & Classrooms: Ensures clear speech reproduction for lecture capture and remote learning.
• Committee Rooms: Facilitates structured discussions with visual status indicators for moderated meetings.

Installation and Setup Guide

Setting up the NCS-5D is an efficient process thanks to its “Plug n Play” design. Integrators should use standard Category 5 or 6 cabling to connect the first unit to the central controller’s extension port. Subsequent units are then daisy-chained together. It is recommended to use high-quality cables to ensure consistent power delivery and signal integrity over long runs. Because the system automatically detects connected units, no complex manual addressing or programming is required at the microphone level.

Delegate vs. Chairman: Understanding the Hierarchy

While the NCS-5D delegate unit allows participants to speak and mute their own microphones, it is designed to work in tandem with the NCS-5C Chairman Unit. The primary difference lies in control: the Chairman Unit features a priority “Override” button. This allows the meeting moderator to instantly mute all active delegate units, ensuring order during intense discussions. Both units share the same high-quality audio specifications and aluminum build, maintaining a uniform aesthetic across the conference table.

System Compatibility & Components

To build a complete Novo Conference System, the NCS-5D should be used in conjunction with:

• NCS110-CU Controller: The intelligent backbone that manages all audio and camera tracking.
• NCS-5C Chairman Units: For meeting moderators requiring priority control and override functions.
• NCS-5DF Flush Mount Units: For architectural integrations requiring a recessed, permanent installation.
• NEB-124W Extension Boxes: Required for systems exceeding the base power capacity or units.
