Yes, XLR Line level out from Mixpre-D. I made the cable, as I didn't want to pay for the Nagra XLR stereo cable.
I used the mono XLR mic cable that came with the SD. Opened up the plastic clip-on, and there are 3 extra wires in there for the line-level input side of the SD.
I use a more flexible Mogami mic cable and connected to these 3 leads.. (THEY ARE REALLY THIN WIRES!)
On the XLRF side for the mixpre-D, I wired it as SD says to for unbalanced output... don't connect or use pin 3 on the XLR.
When turning on the -20dBfs slate tone on the Mixpre-D, the input control on the Nagra has to be turned completely down, and the tone comes into the Nagra at about -19dBfs.
I thought there might be some distortion, possibly over driving the input of the Nagra.. there isn't any!
