This B&H Kit
pairs a Blackmagic Design Mini Converter Audio to SDI
with a Switronix Powertap Blackmagic Converter Cable
. The pairing enables the field use of the audio-embedding device by converting the unregulated DC power from an existing Li-Ion brick-style battery with a Powertap output (not included
) to match the 12V power input of the Mini Converter.
The kit is handy for any situations in which you want to embed audio into an SDI stream and you don't have access to a wall plug, such as ENG and EFP scenarios. The audio can come from a device such as a field audio mixer or a small digital audio recorder. The video (as either SD or HD-SDI) could come from a camera or a portable video recorder/player device with SDI output. The Mini Converter accepts up to four channels of analog audio or up to eight channels of digital AES/EBU audio, performs either sample-rate conversion or analog-to-digital conversion, and embeds the channels into the SDI video stream. This output can then be recorded or transmitted as an embedded SDI signal.
The Switronix cable accepts a battery's Powertap output and supplies regulated 12V power to the Blackmagic Mini Converter, enabling its use in the field. The Blackmagic Mini Converter features a cable tie point that secures the power supply connection, thus preventing an accidental power disruption.
