RGB-HDMI 300 A RGB and Stereo Audio to HDMI Scaler 60-1074-01

The Extron RGB-HDMI 300 A is a high performance RGB and stereo audio to HDMI scaler that converts incoming analog component video and RGBHV signals to HDMI signals. It accepts HDTV and high resolution computer-video signals up to 1920x1200, and offers multiple output rates up to 1920x1200, including HDTV 1080p/60 and 2K. The RGB-HDMI 300 A also offers audio embedding so that analog audio input signals can be digitized into the scaled HDMI output. It is housed in a compact, low-profile enclosure for placement behind flat-panel displays, and offers several features for streamlining integration and enhancing system operation, including Auto Input Memory, Auto-Image™ setup, and RS-232 serial control.

The RGB-HDMI 300 A is ideal for various applications where newer consumer-based displays, equipped only with HDMI inputs, are to be used with sources that output analog RGB, or in an environment with an existing analog RGB and audio signal distribution infrastructure. It can also be used in systems where consolidation of various source signals to a single, common output resolution is desired. For example, the RGB-HDMI 300 A can be installed at the output of a switcher, with its HDMI output feeding the display.

In addition to high performance scaling, the RGB-HDMI 300 A includes several integrator-friendly features for expediting setup and system operation. An on-screen display facilitates display of information pertaining to the incoming signal and adjustment of picture settings, including positioning, size, zoom, brightness, contrast, and detail. Internal test patterns are available for calibration and setup. Configurations can be conveniently saved and recalled from up to three memory presets from the front panel, and up to 16 additional presets through RS-232 serial control.

With Auto Input Memory, the RGB-HDMI 300 A automatically stores image settings for each new incoming signal. When the signal is recognized again from a newly connected source, image settings are automatically restored. Auto-Image, a feature common to many Extron scalers and signal processors, allows for quick and easy setup of incoming analog RGB signals.

The RGB-HDMI 300 A features RS-232 serial control with front and rear ports. It is housed in a 1" high, half rack width enclosure that allows for discreet installation, such as behind a flat panel display or above a projector.
