Datavideo DAC-45 4K Up/Down/Cross converter

Datavideo DAC-45 4K Up/Down/Cross Converter – 4K up conversion with built-in super resolution engine

The Datavideo DAC-45 performs up, down and cross conversion between multiple video formats while providing 4K up conversion using a built-in super resolution engine. It converts SD, HD and computer signals into professional 4K HDMI or 3G-SDI outputs, and embeds external audio when needed. The unit also supports professional sync references and provides I/P conversion to improve image quality.

Main capabilities

• 4K up conversion: The DAC-45 uses a super resolution engine to up-convert from SD 480 resolution all the way to 4K, maintaining improved image quality and sharpness.
• Wide range conversion: Convert VGA, HDMI and SDI inputs to 4K HDMI or 3G-SDI outputs. The unit supports multi-format up, down and cross conversion for broad compatibility between devices.
• External audio embedding: RCA inputs let you embed separate audio into the video output stream, simplifying integration of external audio sources.
• 3G-SDI Level A/B support: The DAC-45 accepts 3G-SDI inputs in both Level A and Level B formats, increasing compatibility with a range of SDI equipment.
• Reference input: Supports Black Burst and Tri-Level Sync for all inputs so you can keep signals properly genlocked within a larger system.
• Built-in de-interlacer and interlacer (I/P conversion): The unit performs I/P conversion to avoid dense, misaligned horizontal lines on interlaced video, delivering a cleaner progressive image.
• HDMI color space adjustment: Use DAC CENTER software to adjust HDMI color space. The DAC-45 supports various resolutions and HDMI color spaces so consumer laptops can be integrated into a professional workflow.
• Rack installation: For rack-mounted setups, the RMK-1 rack accessory allows two DAC-45 units to be installed in a standard 19" rack.

What’s included

• 1 x DAC-45
• 1 x AD Switch DC 12V

Typical use cases

• Upscaling archival SD footage to 4K for presentations or broadcast where higher resolution is required.
• Converting and routing signals between computers (VGA), consumer HDMI sources, and professional SDI infrastructures.
• Embedding external audio via RCA inputs when sources provide separate audio feeds.
• Integrating consumer laptops into pro workflows by adjusting HDMI color space to match professional monitors and recorders.
• Installing multiple units in a 19" rack using the RMK-1 accessory for compact, professional installations.

Why these features matter

Because the DAC-45 supports multiple input types and up to 4K outputs, it reduces the need for multiple converters in a signal chain. The super resolution engine improves perceived detail when up-converting lower-resolution sources. In addition, reference input support and 3G-SDI Level A/B compatibility simplify integration into professional broadcast and live-production setups. Finally, HDMI color space adjustment via software helps match consumer devices to professional displays and recorders.
