Extron DSC HD-12G A – HDMI to 12G-SDI Scaler with Stereo Audio

Product Overview

DSC HD-12G A, part number 60-2060-01. The Extron DSC HD-12G A is an HDMI to 12G-SDI scaler with dual mirrored outputs, converting HDMI video into 12G-SDI, 6G-SDI, 3G-SDI, or HD-SDI for broadcast and production infrastructure. It accepts input resolutions from 480i through 4K/60 and produces selectable SDI output formats from 720p to 4K/60, so the signal lands in the format the downstream router or switcher expects. The Extron Vector 4K scaling engine performs the conversion, with logo image keying available on the output. Two simultaneous SDI outputs feed a switcher and a recorder without an external distribution amplifier.

Product Description

Getting AV sources into a production chain is a routine requirement in broadcast studios, worship facilities, and lecture capture environments. The laptop, room PC, or presentation system speaks HDMI; the production infrastructure speaks SDI at a specific rate. A converter alone forces the downstream equipment to deal with whatever resolution arrives.

The DSC HD-12G A scales during conversion. Input handling covers one HDMI or DVI input on a female HDMI connector, accepting resolutions from 480i through 4K/60 with a 600 MHz maximum pixel clock and up to 18 Gbps HDMI data rate. Output formats are selectable from 720p to 4K/60 across 12G-SDI, 6G-SDI, 3G-SDI, and HD-SDI, which means the operator picks the format that matches the plant rather than negotiating with the source.

Two simultaneous mirrored SDI outputs are provided. In practice that removes a distribution amplifier from the rack: one output goes to the production switcher and the second to a recorder, a stream encoder, or a confidence monitor, both carrying the same scaled signal.

Chroma sampling supports 4:4:4, 4:2:2, and 4:2:0, with 4:2:0 accepted on input only and 4:2:2 on the output side. Color bit depth is 8 or 10 bits per color, with 10-bit available on output. Supported frame rates are 24, 25, 30, 50, and 60 fps. Logo image keying composites an identifier onto the output without a separate device. For the opposite direction, SDI into scaled HDMI, specify the Extron DSC 12G-HD A.

Key Features

• HDMI to multi-rate SDI — Converts HDMI video into 12G-SDI, 6G-SDI, 3G-SDI, or HD-SDI to match the downstream plant.
• Two mirrored SDI outputs — Feeds a production switcher and a recorder or encoder simultaneously without an external distribution amplifier.
• Extron Vector 4K scaling — The Vector 4K engine scales during conversion so output resolution is controlled rather than inherited.
• Wide input range — Accepts HDMI input resolutions from 480i through 4K/60 at up to 18 Gbps.
• Selectable output formats — SDI output rates selectable from 720p to 4K/60 to suit the production infrastructure.
• Logo image keying — Composites a station or institutional identifier onto the output without a separate keyer.
• Stereo audio support — Carries stereo audio alongside the video for complete signal delivery into the production chain.
• Broad frame rate support — Handles 24, 25, 30, 50, and 60 fps across film, broadcast, and computer sources.

Typical Applications

Frequently Asked Questions

Why two SDI outputs?

The two outputs are mirrored, carrying the same scaled signal. That lets one feed a production switcher while the second goes to a recorder, stream encoder, or confidence monitor, removing a distribution amplifier from the rack.

What input resolutions are accepted?

480i through 4K/60 on a single HDMI or DVI input, at up to 18 Gbps with a 600 MHz maximum pixel clock.

Which SDI output rates can I select?

720p through 4K/60 across 12G-SDI, 6G-SDI, 3G-SDI, and HD-SDI. The selectable output means the signal arrives in the format your plant expects rather than whatever the source produced.

Does it accept 4:2:0 sources?

Yes, on the input side. Output chroma sampling is 4:2:2. Color bit depth is 8 or 10 bits per color, with 10-bit available on the output.

Can I add a logo to the output?

Yes. Logo image keying and display is built in, so a station identifier or institutional mark can be composited without a separate keyer in the chain.

What handles the opposite direction?

The Extron DSC 12G-HD A converts multi-rate SDI into scaled HDMI, with an SDI loop output. Facilities bridging both directions commonly specify the pair.

What warranty and support apply?

Extron provides a manufacturer warranty, and Creation Networks coordinates warranty and RMA handling as well as pre-sale signal path review.
