Know before you buy
Yes, the VP-4x4K supports audio breakaway switching, which allows you to route audio signals separately from the video signals to different outputs.
Delayed Switching helps prevent visual glitches or 'tearing' during transitions. You can customize this delay for up to 3.5 seconds to ensure a clean, professional switch between sources.
Yes, the device features a 400MHz bandwidth and built-in signal amplification, which helps maintain high-resolution image quality even when distributing signals across your AV setup.
You have several options for remote control, including Ethernet, RS-232, RS-485, and the included IR remote. This flexibility allows for easy integration into existing control systems or simple operation from across the room.
The switcher uses KR-ISP Advanced Sync Processing, which restores sync signals to ensure broad compatibility with a wide range of computer graphics sources, even those that might otherwise struggle with standard matrix switchers.
Yes, the VP-4x4K allows you to store and recall your favorite setups, making it easy to quickly return to a specific configuration without having to manually re-route every input and output.
