My experience is that there is noticeable hiss in the Meyer UPJ-1P's that I use for my shop monitors when connected to any X32, and that the hiss stays the same regardless of the master fader position. That was alarming until I then connected my previous best small analog console, the APB Dynasonics House Rack. The hiss was the same or somewhat less (it's a long time ago that we did this) on the APB with the master fader off, but went up very drastically when the fader was in its usual 0 db position. We never heard the APB through a PA when used in a real situation, and we never worried again about the X32 hiss at idle. My guess for your situation is that you have an effect return or something else that is up when you don't think it's up, or that you have a bad console. There was a documented and notable whine coming out of the outputs at some settings on some consoles, and Behringer seemed to find and fix it eventually. If you search the X32 megathread for "console whine" or something like that I and others wrote a lot about it a little more than 2 years ago.
