RetroScaler GBS-Control Pro (GBSC PRO) Upscaler/Converter - HDMI Output

Connect a wide range of original retro gaming consoles, computers and compatible arcade hardware to a modern HDMI television, monitor or capture device with the RetroScaler GBSC Pro.

The GBSC Pro is a flexible low-latency retro gaming upscaler designed to convert RGB SCART, RGBS, RGBHV, RGsB, YPbPr component, VGA, composite and S-Video signals into digital HDMI output at up to 1080p. Its broad input support makes it particularly useful for mixed retro console collections where different systems require different analogue video connections.

Unlike basic plug-and-play HDMI adapters built for a single console, the RetroScaler GBSC Pro provides extensive control over scaling, deinterlacing, picture positioning and image presentation. Selectable HDMI output modes include 720p, 960p, 1024-line and 1080p presets, allowing the output to be matched more closely to the connected source and display.

The built-in motion-adaptive deinterlacer makes the GBSC Pro particularly useful for systems and games that rely heavily on 480i or 576i video. Interlaced signals are converted into a cleaner progressive HDMI output while retaining responsive controls and reducing the visible flicker associated with basic bob deinterlacing.

Classic 240p and 288p systems also benefit from low-latency scaling, adjustable scanlines, sharpening, filtering and image-position controls. The scaler is designed to maintain a stable HDMI output when a game switches between progressive gameplay and interlaced menus, helping to reduce the long signal interruptions that can occur with some modern televisions.

Composite and S-Video inputs allow many original consoles to connect without an RGB modification. For the strongest picture quality, RGB SCART and YPbPr component remain the preferred connections wherever the console provides a compatible signal.

Pair compatible systems with one of our Premium On-Sync RGB SCART Cables for a clean, correctly wired RGB connection. Component, composite, S-Video and VGA systems require the appropriate console-specific cable.

Settings can be controlled using the included infrared remote, the built-in OLED display and rotary control knob, or the Wi-Fi web interface. Saveable profiles allow different settings to be stored for individual consoles, video standards and display preferences, reducing the need to configure the scaler each time the connected system changes.

Picture controls include scaling, positioning, borders, brightness, contrast, saturation, sharpening and filtering. Advanced controls provide additional options for ADC calibration, frame-time locking, scanline presentation and signal compatibility.

With support for composite, S-Video, RGB SCART, component and VGA in a single unit, the RetroScaler GBSC Pro provides a practical centrepiece for a multi-console retro gaming setup.

This Is The GBSC Pro: This listing is for the RetroScaler GBSC Pro with composite, S-Video, RGB SCART, component, VGA and HDMI support. It is not the older GBS-Control model with analogue video outputs.

HDMI Video Output Only: Video is output through HDMI at up to 1920 × 1080. The unit also provides a separate 3.5mm stereo audio output but does not provide VGA, RGBS or component video output.

Available HDMI Resolutions: Selectable output modes include 1280 × 720, 1280 × 960, 1280 × 1024 and 1920 × 1080.

NTSC & PAL Matched Presets: The 1280 × 960 preset is designed for NTSC-format sources, while 1280 × 1024 is intended for PAL-format sources. With matched presets enabled, the GBSC Pro can select the appropriate output for the detected signal.

RGB SCART & Component Recommended: Composite and S-Video are supported, but RGB SCART and YPbPr component generally provide a cleaner source signal with stronger colour separation and greater image detail.

Scanlines Require A 240p Or 288p Source: The scanline option is intended for low-resolution progressive signals. It is not designed for 480i, 576i or higher-resolution sources.

Smoothing Has Limited Availability: The smoothing option is intended primarily for composite and S-Video sources operating in the 2x processing mode.

Composite & S-Video Processing Modes: The AV and S-Video module can operate in 1x or 2x modes. DoubleLine mode converts compatible interlaced composite or S-Video signals into progressive output.

Motion-Adaptive Deinterlacing: Motion-adaptive processing is recommended for 480i and 576i material because it reduces flicker while retaining more detail than basic bob deinterlacing. Some artefacts may still be visible around moving objects.

Bob Deinterlacing: Bob mode provides a faster alternative with very low processing delay but can create visible vertical movement around text, menus and fine horizontal details.

Seamless Resolution Switching: The GBSC Pro is designed to maintain its HDMI output when the source changes between modes such as 240p and 480i, reducing the long blank-screen interruptions experienced with some scalers and displays.

SCART Cable Wiring: Use correctly wired EuroSCART cables. Japanese JP21 cables use the same physical connector with a different pinout and must not be connected directly.

Premium RGB Cables Available: Browse our Premium On-Sync RGB SCART Cables for compatible Sega, Nintendo, Sony and other retro console connections.

Manual Input Selection: Inputs are selected through the on-screen display. Connecting several sources does not create an automatic input-switching system.

50Hz To 60Hz Conversion: An optional conversion mode is available for displays that cannot accept 50Hz video. Frame-rate conversion can introduce motion judder and should only be enabled when required.

External Power Required: The GBSC Pro requires a regulated 5V DC power supply capable of providing at least 4A. A compatible UK power supply is included.

Use The Correct Power Supply: Replacement supplies must provide 5V DC through a 2.1 × 5.5mm centre-positive connector. Incorrect voltage, polarity or insufficient current may cause unstable operation or permanent damage.

USB-C Ports Are For Firmware Updates: The two USB-C service connections are used to update the Wi-Fi controller and AV/S-Video module. They are not used to power the GBSC Pro.

Firmware Updates Are Optional: Only install firmware specifically intended for the RetroScaler GBSC Pro and follow the correct update procedure for the relevant module.

Remote Batteries Not Included: The infrared remote control requires two AAA batteries.

HDMI Cable Not Included: A standard HDMI cable is required to connect the GBSC Pro to a television, monitor, AV receiver or capture device.
