The unit is HDCP compliant and Blu-ray ready, ensuring compatibility with modern copy-protected media and devices. A combination of robust construction and intuitive control options helps you keep audiences engaged and presentations uninterrupted.

• Flexible, effortless source switching — Access four input sources and switch between them quickly with the front panel controls, the included IR remote controller, or via RS-232 for integrated control in custom AV ecosystems. This multi-access approach means you can manage presentations from the podium, by the display, or through centralized control software, providing real-time responsiveness in demanding environments.
• Premium video and audio support — The switch handles video routing for resolutions up to 1080p and 1920 x 1200, ensuring sharp images on contemporary displays. Audio is carried along with the video so you can enjoy synchronized sound from any source. HDCP compliance guarantees compatibility with protected content, making it suitable for professional deployments, conference spaces, and Blu-ray playback setups.
• EDID copy function for seamless compatibility — An optional EDID copy feature ensures your sources negotiate correctly with the display, preserving the best possible picture and audio settings. This helps prevent display incompatibilities and reduces setup time when devices from different manufacturers are used in the same system.
• Compact, durable design for professional environments — Built to withstand daily use in conference rooms, classrooms, and entertainment spaces, the Black Box switch combines a sturdy form factor with straightforward installation. Its clean, low-profile footprint fits neatly into AV racks, under desks, or on shelves, keeping cables organized and your workspace uncluttered.
• Simple integration with existing AV setups — Whether you’re upgrading an older system or building a new one, this 4x1 DVI switch integrates smoothly with your current sources and displays. The combination of front-panel control, remote operation, and RS-232 compatibility makes it easy to add to existing control schemes and automation workflows, reducing downtime during transitions and ensuring presenters can focus on content rather than configuration.

How to install Black Box 4 x 1 DVI Switch with Audio

• Plan your layout — Place the switch in a convenient location near your display and source devices. Ensure there is easy access to the front panel and enough space for cable management. A clean, well-ventilated setup helps maintain performance and longevity.
• Connect video sources — Attach each of your four video sources to the four DVI input ports. Use high-quality DVI cables to minimize signal degradation and preserve image clarity. If your sources require audio, connect audio as appropriate so that the switch can route both video and audio to the display system.
• Connect the display — Connect your display device (monitor or projector) to the single DVI output port. Verify that the display accepts the output resolution you intend to use (up to 1080p or 1920 x 1200).
• Configure control — Decide how you will switch sources. You can use the front-panel buttons for quick local switching, the included IR remote for room-wide control, or integrate RS-232 commands into your control system for automated switching and macro operations.
• Set EDID as needed — If you encounter any compatibility issues, use the EDID copy function to mirror the display’s EDID to the sources. This helps ensure the best possible picture and audio synchronization across devices.
• Test the setup — Power on all sources and the display, then perform a test routine to switch between inputs. Confirm that both video and audio route correctly and that HDCP-protected content plays without issue on your display.
• Fine-tune integration — If you’re integrating with a control system, program RS-232 commands or remote-control presets to streamline daily use. Document your input assignments so presenters can quickly select the desired source by name or room activity.
