Hi
A while ago, I was working on an instrument where I had to convert several Hi-Z inputs into microphone level, literally a DI ! and I made this assembly with things I have at home. The Idea was mostly that the DI is fixed inside the instrument.
Long story short, (as I needed to buffer the severals input at first) I don't used it. But today as I was cleaning my stuff I came accross it, plug it, play with... and it don't sound bad !
It consist on the Hi-z plug-in from CAPI, used on his 312 DI : Classic Audio Products, Inc.
and an output transformer. (here a VTX-101-006, 1:1 150/150)
Simple !
It supposed to be powered by a +16v (or +24v) but I used +12v from a simple AC to DC.
I'd be very happy to move out the Power supply and powered it from +48v.
Could it be possible/work adding a few component like 2x 6k81 before the transformer and maybe some others like on a BO hansen ?
here the plug-in schematic : https://capi-gear.com/catalog/images/gallery/HiZ-Plug-In/active/HiZ-FET1-rev01-schematic.pdf
