SDI-to-Analog 4K Converter

The Blackmagic Design Mini Converter CONVMASA4K translates single-link SD, HD, 3G and 6G-SDI signals into analog component, composite and S-Video outputs. It serves broadcast engineers, post-production facilities and live-event crews who need to integrate modern UHD sources with legacy monitoring or recording equipment.

Signal and Power Requirements

Verify that your source equipment delivers SDI compliant with SMPTE 259M, 292M, 296M, ITU-R BT.601 or BT.656 at 4:2:2 sampling. The unit draws 8.04 watts from the supplied 12 V universal power supply with international socket adapters and operates between 0 °C and 40 °C with 0 to 90 percent non-condensing humidity.

Sustained Operation Behaviour

Automatic input detection re-locks continuously across format changes without manual intervention. Audio remains at 24-bit, 48 kHz through both balanced 1/4-inch analog and AES/EBU digital outputs during extended sessions. Firmware upgrades via USB on macOS 10.9 or later and Windows 7 or 8 keep the converter current for long-term deployments.

Questions about this item

What comes in the box with the CONVMASA4K and what must I purchase separately?

The package includes the Mini Converter SDI to Analog 4K, a software CD and a 12 V universal power supply with international socket adapters. SDI and analog cables are not included and must be bought separately.

Which SDI standard should I select for 3840x2160p30 input?

Choose the 6G-SDI setting on the single-link input; the converter automatically detects 4K formats up to 3840x2160p30 and down-converts them to the selected analog output.

What does the 8.04 W power figure mean for daily operation?

The unit draws 8.04 W from the supplied 12 V supply, so it runs cool within the 0 °C to 40 °C operating range and can stay powered continuously in a rack or on location.
