The DAC-45 connects VGA, HDMI and HD/SD-SDI sources to HDMI output up to 4K and to 3G-SDI. It converts up, down and across formats, helping integrate legacy computer or studio signals into a modern chain while adapting resolution and frame rate.
VGA, HDMI or HD/SD-SDI input can be converted to HDMI up to 4K or to SDI. All outputs are active at the same time, so the DAC-45 can distribute the signal to multiple downstream devices in a compatible setup. It supports 3G-SDI Level A and B, and built-in interlacing processing converts between interlaced and progressive formats.


Two unbalanced RCA inputs let you add external stereo audio to the video output. The DAC-45 carries embedded HDMI and SDI audio in PCM at up to 8 channels and 48 kHz. This is useful when converting a computer picture that needs a separate audio input.
The reference input supports Black Burst and Tri-Level Sync. HDMI color space can be adjusted in DAC CENTER software; the Proc Amp provides video adjustment, while the SDI output supports equalization, reclocking and cable drive. Mini USB is used for device updates and configuration.


The optional Datavideo RMK-1 kit installs one or two compatible DAC-45 converters in a 19-inch rack. An integrated HDMI strain relief helps protect the connector from cable stress, and the switch-setting chart is printed on the underside of the unit.
Choose an HDMI cable length to connect your source and destination devices in the production setup. For SDI, use a 75-ohm BNC cable with BNC connectors. The optional RMK-1 kit mounts one or two DAC-45 converters in a 19-inch rack.
