Product information

Description

The Gefen EXT-HD-3G-C converts HDMI audio and video to 3G‑SDI and single-link HD‑SDI, supporting resolutions up to 1080p Full HD and audio formats up to 8-channel LPCM. The compact converter supports discovery, configuration and firmware updates via the Gefen Syner-G™ software suite, and offers multiple mounting options and a wide-range DC input with a locking power connector for reliable use in mobile or fixed A/V installations.

Advantages

The EXT-HD-3G-C provides reliable HDMI-to-SDI conversion with support for Full HD and multi-channel LPCM audio. Its small, lightweight enclosure includes an ISO standard 1/4-20 attachment thread and a detachable surface-mounting bracket, and it can also be held in place with double-sided Velcro®. The device features a locking power connector and flexible DC input circuitry, and integrates with Gefen Syner-G™ for EDID customization and firmware management.

Key specifications

  • Input: HDMI (locking HDMI cable included)
  • Output: 3G‑SDI and single-link HD‑SDI
  • Video support: up to 1080p Full HD
  • Audio support: up to 8 channels LPCM
  • Mounting: ISO 1/4-20 thread, detachable surface-mount bracket, Velcro® compatible
  • Power: 12 V DC supply included, locking power connector, wide DC input range
  • Management: USB Mini-B port compatible with Gefen Syner-G™ for EDID and firmware updates
  • HDCP: Not compatible with HDCP-encoded HDMI content

How to use

Mount the EXT-HD-3G-C using the 1/4-20 attachment thread, the included surface-mount bracket, or secure it with double-sided Velcro® where necessary. Set DIP switches to the required positions for your workflow. Connect the HDMI source to the HDMI input using the included locking HDMI cable, and connect an SDI cable from the converter output to the SDI display or downstream equipment. Attach the supplied 12 V DC power adapter to the locking power jack; pull back on the adapter’s plastic sleeve to disengage the lock when removing the plug. The power LED will glow blue when powered and the HDMI In LED will glow green when an active HDMI source is detected. Use the USB Mini-B port together with Gefen Syner-G™ software for EDID customization and firmware updates; see the user manual for detailed instructions.

Recommendations

Do not use the EXT-HD-3G-C with HDCP-protected HDMI sources; if the input is HDCP-encoded there will be no SDI output. For reliable operation in mobile setups, use the locking power connector and secure mounting options provided.
