The JVC Professional RM-HP790DU is a sophisticated digital camera control unit (CCU) designed to provide comprehensive remote operation and adjustment of compatible JVC studio cameras, specifically the GY-HM790 and GY-HM890 models when configured with the appropriate studio interface (like the KA-M790G module). This control panel is the central interface for camera operators and engineers in broadcast studios, outside broadcast (OB) vans, and production control rooms, allowing for precise, real-time control over all critical camera functions from a centralized location. It enables the operator to adjust video parameters—such as color balance, detail, gamma, and knee settings—and to control the lens remotely, including zoom, focus, and iris, transforming the camcorder into a fully functional studio camera.

The unit features a high-resolution color monitor that displays the camera's output feed along with essential overlays like tally indicators, status information, and menus. Its control surface is laid out with dedicated knobs, buttons, and joysticks for immediate access to common adjustments, ensuring intuitive operation during live production. The RM-HP790DU connects to the camera via a hybrid multicore or triax cable (such as the VC-DHP112MO), which carries bidirectional video, audio, control data, intercom, and power. This setup allows the camera to be positioned on a studio floor, jib, or remote location while being controlled from the production booth, offering tremendous operational flexibility.

Built to the rugged standards required for 24/7 broadcast environments, the RM-HP790DU is an essential component for any professional production facility utilizing JVC's camera systems. It maximizes the creative and technical potential of the cameras by providing studio-grade control, ensuring consistent image quality across multiple cameras, and streamlining the workflow for live switching and production.
