Kramer Electronics 90-70874090 Hdmi to 3G Hd-sdi Converter

Product Description

The KRAMER ELECTRONICS 90-70874090 is an HDMI to 3G HD-SDI format converter designed to bridge consumer and prosumer HDMI video sources with professional serial digital interface (SDI) infrastructure. It accepts a standard HDMI input signal and outputs a 3G HD-SDI signal, enabling integration of HDMI-equipped devices into broadcast, production, or commercial AV distribution systems that rely on coaxial SDI cabling. This type of converter is a standard tool for AV integrators and broadcast technicians who need to connect HDMI sources to SDI-based routers, monitors, or recording equipment.

This format converter is suited for professional AV and broadcast environments where HDMI sources must feed into SDI signal chains. Typical applications include live production setups, house-of-worship installations, digital signage backbones, and any facility where long-distance coaxial SDI runs are preferred over HDMI. It is typically installed by licensed AV integrators or broadcast engineers working in commercial or institutional settings.

Key Features

• Converts HDMI input to 3G HD-SDI output for professional signal distribution
• Supports 3G SDI standard, accommodating high-definition video formats
• Enables use of HDMI sources within coaxial SDI infrastructure

Installation Notes

Installation is typically performed by a qualified AV integrator or broadcast technician. Power down connected source and destination equipment before making signal connections. Use properly terminated 75-ohm coaxial cable on the SDI output to maintain signal integrity over the run length. Follow applicable local codes and manufacturer guidelines for rack mounting or surface placement.
