The little DC out jack on the side of the TR2—I would like to use it to power an external DC powered headphone booster (Headroom Airhead)

Can someone tell me what kind of connector is on the TR2—and what is the output voltage, etc.?  Also where would I get a cable to connect to that port?

Thanks in advance.

It’s a proprietary firewire power jack. I believe that only Sony equipment use it in conjunction with the 4-pin type (unpowered) firewire jack. I’ve never heard of a converter. I’d love to get a 4-pin + DC to 6-pin converter, but I’ve never seen one.

Bummer, woulda’ been handy to get some power outta there.  Thanks for the answer!
