HDMI 2.1 Ultra High Speed connection for high-performance audio-video systems
The Wireworld Sphere 48 HDMI is an HDMI cable designed to offer reliable performance and flawless transmission of the most advanced audio-video content. Compatible with the HDMI 2.1 Ultra High Speed standard, it supports a bandwidth of up to 48 Gbps, guaranteeing full handling of 8K content, high refresh rate video games and the latest generation of immersive audio formats. It is an ideal solution for home cinema, gaming systems and AV installations that require high signal quality and stability.
Full support for 8K, 4K/120Hz and advanced HDR technologies
Thanks to its HDMI 2.1 certification, the Sphere 48 allows the transmission of video signals up to 8K at 60 Hz and 4K at 120 Hz, delivering detailed, smooth and realistic images. Support for HDR10, HDR10+ and Dolby Vision technologies makes it possible to get the most out of the potential of modern televisions and video projectors, with an extended dynamic range and extremely accurate colour rendition.
OFC conductors and construction optimised for maximum signal integrity
The Wireworld Sphere 48 uses conductors made of OFC oxygen-free copper, selected to ensure efficient transmission of digital data and to reduce signal losses. The dedicated shielding helps to limit electromagnetic interference and external disturbances, keeping the quality of the connection high even in complex systems or environments full of electronic equipment.
Unlike the Radius 48, which uses twisted pairs with triple shielding, the Sphere 48 adopts Wireworld's proprietary Uni-Path™ design, with COMPOSILEX® 3 insulation.
Gold-plated connectors and universal compatibility
Fitted with high-precision HDMI connectors with 24K gold-plated contacts, the Sphere 48 guarantees reliable, long-lasting connections. It is compatible with televisions, monitors, video projectors, AV receivers, soundbars, gaming consoles and streaming devices, ensuring maximum versatility in any modern audio-video configuration.
