4CH RDM LED Decoder with Display

This D4-P controller is a 4-channel constant voltage LED decoder built for reliability in professional DMX environments. It accepts DC12–24V input (confirmed in technical notes — '36V' is inaccurate), supports full DMX512 and RDM protocols, and delivers up to 8A per channel (32A total) via precision PWM outputs. Physical features include XLR3 male DMX input, RJ45 port for alternate signal paths, digital display for real-time status, and tactile front-panel controls. The housing merges plastic and metal components to balance durability, heat dissipation, and mounting versatility. RDM functionality enables automated device enumeration, remote address assignment, and health monitoring — turning what would be a manual, error-prone process into a single-console workflow. Its PWM engine avoids aliasing and ripple, supporting smooth transitions from 0% to 100% brightness without stepping or lag. Designed specifically for constant-voltage LED applications, it excludes unnecessary features like analogue inputs or WiFi — focusing instead on protocol fidelity, thermal safety, and long-term uptime. Frequently deployed in museums, broadcast studios, boutique hotels, and high-end residential automation — wherever lighting must remain stable across seasons, integrate cleanly with building management systems, and support future expansion without hardware swaps.
