JAD-EXM-P Extension Unit

The JAD-EXM-P is a high-capacity power and signal distribution unit designed to expand the reach and reliability of the CLEACON Digital Conference System. While the standard controller manages the core logic, the "P" series extension unit provides the necessary current to drive large-scale microphone chains over long distances. It acts as a critical bridge in massive installations, ensuring that every unit—no matter how far from the central rack—receives stable power and maintains lossless digital audio synchronization.

Key Functional Highlights

High-Current Power Injection: Specifically engineered to provide the high-voltage DC power required for units with OLED screens and motorized components, preventing “voltage drop” that can cause unit flickering or resets in long chains.
Signal Regeneration: Not just a power supply, the JAD-EXM-P actively regenerates the digital data signal, allowing for cable runs of up to 100 meters between the main controller and the extension hub without latency.
Four-Channel Distribution: Features four dedicated RJ45 output ports, allowing a single extension unit to drive four separate branches of microphones, simplifying the wiring of massive “U-shaped” or classroom-style seating.
Intelligent Status Monitoring: The front panel features a matrix of LED indicators that provide real-time feedback on the health of each connected branch, allowing technicians to identify a cable fault or power overload instantly.
Lossless Audio Passthrough: Maintains the uncompressed 48kHz/24-bit digital audio quality across the entire expanded network, ensuring that the last microphone in the chain sounds identical to the first.
Automatic Power-Sync: The unit is designed to power on and off in perfect synchronization with the JAD-DCP2000-D central controller, ensuring the entire system is ready for use with a single button press.

System Configuration Guide

To maintain peak performance in your CLEACON installation, follow these power-loading guidelines:

Standard Units: Add one JAD-EXM-P for every 60-80 additional units.
Multimedia Units (with Screens): Add one JAD-EXM-P for every 40-50 units.
Long Cable Runs: Use an extension unit if the distance between the controller and the first microphone exceeds 40 meters.
