Analog to sdi mini converter

[Bob Zelin]

I have used the Blackmagic analog to SDI mini converter for a Beta 1800 VTR, and it is WONDERFUL. You take the analog CAV video, and embed the analog audio, and it comes out SDI. It’s GREAT. This is an AC powered unit. I am not aware of a way to make it (or the AJA or the Cobalt Digital, or the Miranda Pico converter) battery operated. I do not see any -10dB input switch on this unit, so it probably will NOT amplify or adjust the signal level for a lower audio input (coming from the RCA jacks on your camera).

I have the AJA version for my HVX200, They sell it either AC or battery powered, I have the battery version it plugs into the Anton Bauer battery that also powers the Marshall monitor. I love it, makes connecting the Large panasonic 26″ monitor easy and I can supply SDI to the video assist to down convert. For client viewing.

you run the BT-LH2600W on battery power in the field ??????

Noooo Bob, I can run the AJA mini converter by battery. The monitor is on A/C. With the HVX200 on a dolly, the last thing I need is another AC line coming in on top of all the other cables, Sound, Video etc. Running the AJA box by battery just cuts down on the clutter.

Hi Peter —

are you making your own +5VDC converter cable – because AJA doesn’t sell one. How are you DC powering your AJA mini converter ?

Bob Zelin

[Bob Zelin]

I don’t know what Peter is talking about. AJA does not appear to sell a special DC version of their mini converter line. Certainly a custom cable can be made up. The Blackmagic mini converters take a standard 12VDC power. This means that you can RIG UP a battery (like an Anton Bauer) with the right adaptor (from Radio Shack, etc.) to give the Blackmagic mini converter +12VDC, and do the same thing with this, that you can do with the AJA.

SO PETER, exactly what did AJA sell you go DC power your converter, or did you make up a cable for this ?

BOB, AJA certainly do make a 5v version of this mini converter, (speak to George at AJA) and yes I did make my own cable, but AJA sold me the connectors that they use, they also sent me the the cable diagram(thanks to Kathy Mendoza at AJA). One end of the cable has the twist lock pluck that goes on to the converter box and the other has an Anton Bauer plug that goes into the Zacuto battery holder on the camera rails. Here is a copy of an email that they sentme.

Hi Peter –
I have attached the picture of our Anton Bower cable and the pin out for the female ends that we use. If you need for us to send the ends to you, let us know! If you have any questions or need any other info, please let us know.
Thank you!
Have a great day!
Kathy

Hey bob when you did use it for your beta vtr did you have to mess with the audio signal at all or did it seem right level.

What is cav, is that compenant cable sorry dont know the proper terms.

Peter would you be willing to make me a cable like you did and sell it to me since i have no clue how to make one.
