I remember that NP once said something about how to set up an X series stage for single ended operation. I have searched the forum frantically for that post without success.
I would like to have verified that the standard method for hooking up a single ended input to a balanced amp (i.e shorting the un-used input to ground using a resistance which is the same value as the source resistance) is the recommended way also for X-style units.

Petter,
I believe you short pins 1 and 3 for most of the X-amps. I don,t think the X-1000 or X-600 respond as well to this for some reason, maybe because of the folded cascode?
Why don't you try it? Maybe a transformer on the input is the answer but I don't think the Master favours them. Maybe a simple phase inverter is the solution.

Check A75 article. He explains there how to match source impedance on not driven input. Also this thread contains lot of info on balanced lines. Especially comments by Steve Eddy http://www.diyaudio.com/forums/showthread.php?s=&threadid=6832&highlight=balanced+line
I have tried it, but did not get the expected result, so I was wondering if there was a special trick for doing it.
The reason for testing was that the signal generator + analyzer I was getting access to are both single ended.
Transformers next I suppose 🙂
Will check out links
