Installers needing HDMI-to-SDI distribution

Suited for professionals converting a single HDMI source to dual SDI feeds for monitoring or recording at 1080p. It is not intended for workflows that require resolutions beyond 1920 x 1080 or for installations needing more than two SDI outputs. Buyers without a local AC supply for the included adapter should consider alternative power arrangements.

Dual SDI outputs at 1080p

The converter provides two SDI outputs from one HDMI input, both limited to a maximum resolution of 1920 x 1080. This output count and resolution ceiling determine whether the unit fits a given signal-distribution design.
