I emailed BLA to get some clarity on what is going on with the 002r's in's and outs. Here's their reply:justin3am wrote:I'm under the impression that the a stock 002 is not DC coupled. The 192I/O and 96I/O definitely have DC blocking caps on their outputs. I used to have a BLA modified FireWire 1814 and one of the modifications they made to that device was removing the DC blocking caps. I'll bring an 002 and an 003 home with me tonight and report back with my results.
There are no output coupling caps on the line outputs of the 002R. There are inductors on all of the inputs and outputs, but DC will still pass through an inductor. We don't alter any aspect of that portion of the circuitry. It shouldn't be much of a big deal if you want to remove them.
