The XTP fiber optic products are compatible with the XTP Systems family, and share many of the features and capabilities found on other XTP boards and extenders. For streamlined integration, the XTP FT HD 4K transmitter includes an HDMI Loop‑through with selectable audio control and enables embedding of analog stereo audio signals while the XTP FR HD 4K receiver provides selectable HDMI audio pass‑through, audio de‑embedding to digital S/PDIF or analog stereo audio outputs, and relays for environmental control at the destination. The XTP SFR HD 4K fiber optic scaling receiver also features Extron Vector 4K scaling technology to support modern and legacy display devices. All XTP devices are compatible with one another. This compatibility enables complete end-to-end system solutions, and provides a wide range of possibilities for future system upgrades to support video standards and formats of 4K and beyond.
