Erthpot NEB-124W Extension Box
Professional Power Expansion Module for NCS Novo Conference Systems
The Erthpot NEB-124W is a high-performance signal repeater and power expansion module designed specifically for the NCS Novo Conference System. Its primary role is to provide stable 24V power and signal amplification to support large-scale microphone deployments in legislative halls and corporate boardrooms. By connecting seamlessly via standard network cabling, it allows for the expansion of the delegate network from a baseline capacity to a massive 110-unit system. In modern professional AV environments, this expansion unit is critical for maintaining audio integrity and power consistency across long cable runs.
The Role of Extension Units in Digital Conference Architecture
In digital discussion systems, the central controller often has limited current-driving capacity for the daisy-chained microphone units. A conference system extension box like the NEB-124W acts as a localized power injector and signal buffer. By placing these modules strategically within the wiring topology, system designers can extend the physical reach of the network far beyond the standard limitations of a single controller.
Beyond simple power, these units manage the complex task of “refreshing” the digital communication data. This ensures that even the 110th microphone in a chain receives the same low-latency, high-fidelity signal as the first, effectively eliminating the risk of signal degradation or unit brownouts in mission-critical government or judicial environments.
Core Engineering Features
30-Unit Power Injection
Equipped with a built-in 72W/24V power module, the NEB-124W provides sufficient current to power up to 30 additional microphone units from a single localized point.
Active Thermal Management
Features an integrated cooling fan system that automatically regulates internal temperatures, ensuring 24/7 reliability even during high-power operation in enclosed racks.
Dual Network Connectivity
Utilizes dedicated RJ45 input and output terminals for high-speed data relay, facilitating a clean, professional daisy-chain topology using Cat5 or Cat6 cables.
Visual Status Monitoring
A dual-mode LED indicator provides immediate visual feedback: red for standby mode and blue for active system communication, simplifying troubleshooting for site engineers.

System Integration & Topology
The NEB-124W operates as a critical bridge between the NCS110-CU central controller and the delegate microphones. The controller initiates the data stream, which travels through the network cable to the extension box. Inside the NEB-124W, the digital signal is regenerated, and the DC power rail is reinforced to 24V before being transmitted to the next cluster of microphones.
- Network Stabilization: Prevents voltage drops over long-distance cable runs.
- Microphone Networking: Enables complex multi-row and multi-table layouts.
- Audio Fidelity: Maintains uncompromised audio stability across a maximum of 110 connected units.
Ideal Installation Environments
- • Government Assembly Halls: Supporting hundreds of voting delegates.
- • Judicial Courtrooms: Ensuring power for judge, witness, and counsel microphones.
- • Corporate Boardrooms: Managing distributed microphones across large tables.
- • University Lecture Theatres: Providing connectivity for interactive student seating.
- • Convention Centers: Scalable audio distribution for multi-purpose halls.
