Blackmagic Mini Converter Audio to SDI

The Blackmagic Design Mini Converter Audio to SDI embeds analog or digital audio into an SDI video stream. It suits broadcast engineers and post-production facilities that need reliable format conversion with redundant signal protection. The unit accepts balanced analog and AES/EBU inputs through standard quarter-inch jack connections.

Supported formats and capacity limits

Handles 625/25 PAL, 525/29.97 NTSC, 720p at 50, 59.94 and 60, 1080i at 50, 59.94 and 60, plus 1080PsF at 23.98, 24 and 25, all at 4:2:2 sampling. The SDI interface switches between SD, HD and 3 Gb/s rates automatically. It does not support higher frame rates, 4K resolutions or uncompressed multi-channel workflows beyond the eight digital and four analog channels provided.

Thermals, noise and power draw

Operates from an included 12 V DC supply with no internal fan, so acoustic output is negligible in studio environments. Power consumption remains low during continuous conversion and automatic changeover between the primary and redundant SDI inputs. The compact metal enclosure dissipates heat passively without requiring forced airflow.

Questions about this item

Will the CONVMCAUDS accept 525/29.97 NTSC and 625/25 PAL from my legacy decks?

Yes, it supports both 525/29.97 NTSC and 625/25 PAL alongside 720p and 1080i formats, and auto-switches between SD and HD when the input changes.

How can I verify the redundant SDI input is active after installation?

The converter automatically switches to the redundant SDI input if the main SDI signal is lost, so a stable SDI output during a main-cable disconnect confirms it is working.

Does the box include the 12 VDC power supply and cables for the 1/4 inch AES/EBU and analog audio jacks?

The 12 VDC power supply is included; AES/EBU and analog audio cables with 1/4 inch connectors must be purchased separately.
