Extron RGB 406 Mountable Interface w/ Audio BNC DB9 12V Wall Plate AV

Extron RGB 406 Mountable Interface w/ Audio BNC DB9 12V Wall Plate AV

The Extron RGB 406 is a wall-plate-mountable RGB interface designed to integrate computer video and audio signals into presentation and AV distribution systems. It accepts an RGB computer signal via a DB9 input, outputs via a five-wire BNC breakout cable, and converts unbalanced computer audio to a balanced audio signal — making it well suited for routing computer AV through professional audio systems. The unit mounts into a standard single-gang electrical box cutout and presents a clean faceplate in the finished installation.

Applications

The Extron RGB 406 is a product from Extron's line of signal interfacing and distribution equipment, aimed at professional AV and presentation environments. Wall-plate RGB interfaces like this one are used in conference rooms, classrooms, auditoriums, and training facilities where a presenter needs to connect a laptop or desktop computer to a room's projector or display system through a structured cabling infrastructure. The DB9-to-BNC breakout design bridges the computer's video output to a coax-based distribution system, while the built-in unbalanced-to-balanced audio conversion allows the computer's headphone-level audio output to feed directly into a professional audio system or sound reinforcement setup without a separate DI box. The switchable 75-ohm/High-Z input termination makes the unit compatible with both driven and passive signal sources. Extron introduced the RGB 400 series wall-plate interfaces in the late 1990s and early 2000s to serve the rapid growth of laptop-based presentations in corporate and educational AV systems during that era.
