Datavideo DAC-9P 4K HDMI UHD-Video to UHD/SD-SDI Converter

Datavideo DAC-9P 4K HDMI to 12G-SDI Converter — converts up to 4K50/60 for broadcast workflows

The Datavideo DAC-9P 4K converts 4K HDMI signals up to 4K50/60 into professional 12G-SDI outputs. It lets you connect 4K HDMI devices directly to SDI infrastructures and provides a convenient HDMI loop-thru for monitoring or daisy-chaining other devices.

Simple connection and operation

The DAC-9P 4K works as a plug-and-play converter, so you do not need a laptop or dip switches to adjust settings. Just connect your HDMI source and SDI destination and you will receive a stable SDI video signal ready for production.

Key features at a glance

• Supports DCI and UHD 4K: Handles DCI 4K (4096 x 2160) and UHD 4K (3840 x 2160).
• 4K HDMI 2.0 input with Loop-Thru: One HDMI 2.0 Type A input plus one HDMI 2.0 Type A loop-through output to feed additional devices.
• 12G-SDI outputs: Two 12G-SDI outputs (3G-SDI Level A) for integration with SDI equipment and multi-destination workflows.
• Re-clocking: Regenerates the video signal to reduce jitter and support longer distance SDI transmission.
• Audio embedding: Embed audio into SDI from either HDMI embedded audio (24-bit, 8-channel) or from 2-channel RCA analog inputs.
• Durable metal housing: Rugged aluminum design with low heat dissipation for long-hour operation in normally ventilated environments.
• Firmware updates and configuration: USB Type-C port for updates and configuration tasks.

How it fits into live production and broadcast

Use the DAC-9P 4K to bridge HDMI-based 4K cameras, media players or switchers to professional SDI routers, recorders and transmitters. The HDMI loop-thru lets you keep a local monitor or pass the HDMI feed to another device while converting the main signal to SDI. Because the unit reclocks the output, it helps maintain signal integrity over longer SDI cable runs, which is important in live production environments.

Audio options and flexibility

The converter embeds audio into the SDI outputs. You can choose HDMI embedded audio (24-bit, up to 8 channels) or feed two-channel unbalanced analog audio via RCA connectors. This gives straightforward options for including program audio in your SDI feed without extra routing gear.

FAQ

Question: Can the DAC-9P 4K handle both DCI and UHD 4K formats?

Answer: Yes. The unit supports DCI 4K (4096 x 2160) and UHD 4K (3840 x 2160) at the frame rates listed in the supported formats.

Question: Do I need a computer to configure the converter?

Answer: No. The DAC-9P 4K is plug-and-play and does not require a laptop or dip switches for normal operation. A USB Type-C port is available for updates and optional configuration if needed.

Question: How can I include audio in the SDI output?

Answer: You can embed audio from the HDMI input (24-bit, up to 8 channels) or select the two-channel RCA analog inputs to be embedded into the SDI output for live production.

Question: Can I monitor the HDMI feed while converting to SDI?

Answer: Yes. The DAC-9P 4K includes an HDMI loop-thru so you can feed a monitor or additional device while the main signal converts to SDI.

Question: Will the converter help with long SDI cable runs?

Answer: The DAC-9P 4K reclocks the video signal to reduce jitter and improve output quality, which supports more reliable transmission over longer SDI cable distances.
