4x4 HDMI Matrix with Audio (4K30Hz / 4K60Hz) Key benefits - Flexible multi-screen routing: route any of four HDMI inputs to any of four HDMI outputs independently. Outputs can show the same source or four different sources at once, so one device can feed multiple rooms or displays without swapping cables. - Preserves high resolution: supports 4K video at 30Hz and 4K at 60Hz where applicable, keeping image quality for streaming devices, players, and consoles. - Simple, reliable control: switch sources using front-panel buttons or the provided dual remote controls for convenient local or distance operation. - Integrated audio extraction: separate 3.5mm and digital (fiber) audio outputs let you send audio to headphones, powered amplifiers, mixers, or external speaker systems without additional converters. Main features - 4 HDMI inputs and 4 HDMI outputs — independent routing and distribution of HD video. - 4K30Hz / 4K60Hz support for high-definition sources and displays. - Dual remote control plus front-panel buttons for multiple switching methods. - 3.5mm analog and digital fiber audio outputs for flexible audio integration with external equipment. Compatibility and performance - Works with standard HDMI sources such as Blu-ray players, streaming boxes, PCs, game consoles, set-top boxes, and AV receivers. - Audio outputs designed to connect to headphones, powered amplifiers, mixers, and other external audio devices for added flexibility in sound setups. - Designed for consistent, low-latency switching and stable multi-display output. Practical use scenarios - Home theater / living room: Connect multiple media players and a game console, then send any source to any TV or duplicate a single source to all TVs for synchronized viewing. - Conference room or classroom: Route laptops and presentation devices to multiple displays around the room while feeding the audio to a PA or mixer. - Retail, sports bar, or digital signage: Display different content on each screen or broadcast a single event across all screens while sending audio to a centralized sound system. What this product solves - Eliminates repeated cable swapping when multiple sources and displays are used. - Centralizes source management for multi-room viewing or multi-display installations. - Separates audio for dedicated sound systems without extra adapters.
