Blackmagic Design Mini Converter SDI to Analog

HD to SD down conversion

Built-in down conversion turns HD pictures into standard definition, so even an HD-SDI signal can feed analog SD devices with an S-Video or composite input. The SDI input accepts SD and HD (1.5G-SDI) and detects the format automatically.

Redundant SDI input

In addition to the main SDI input, the converter has a redundant ALT SDI input. If the main signal is lost, for example when a cable is damaged, the converter automatically switches over to the redundant input. The SDI loop output passes the input signal on.

Audio to separate outputs

The converter de-embeds the audio embedded in the SDI signal to two channels of balanced analog audio on 1/4 inch jacks or to digital AES/EBU (left connector). Sampling at 48 kHz and 24 bit is preserved.

For archives and live work

Connect analog monitors, Betacam SP and VHS decks or other analog equipment to a current SDI route. The converter belongs to the Mini Converter range with analog video, SDI, HDMI and audio conversions.

Setup with mini switches or over USB

Functions are selected with mini switches using the diagram printed on the converter: analog audio or AES/EBU, 7.5 IRE or 0 IRE level, SMPTE or Betacam levels, component or composite/S-Video output and the audio channel pair 1 and 2 to 15 and 16. Over USB and the utility for macOS and Windows, settings can be changed from a computer and new software installed.

About the Mini Converter range

The Mini Converter range is designed for professional broadcast, post-production and AV installations. A compact metal chassis, high-quality connectors and standard cabling make it dependable in studios, control rooms and mobile systems.

Core settings are selected with mini switches using the diagram printed on the unit, while USB is used for configuration and updates. The converter handles supported formats automatically and keeps picture and sound stable throughout the signal chain.

The electronics automatically handle supported SD and HD formats and, on SDI models, keep the signal stable along the whole chain. The result is a practical link between older and current equipment without needlessly complex infrastructure.
