krzys, As an outside observer, I would agree with the previous posters.
Essentially for a fixed system, the same input should yield the same output, but you are implying this is not the case. So, logically, if what you are saying is true - the output is not the same. Then, 1) Is the input the same? Can you play the SAME 0 DBFS signal via your different sources, Sean, and others have provided possible tests to check that the source input (or output from sources) is the same. 2) Is the system indeed fixed? When you used non-SB sources did you use the same cable into the same input on the Behringer, as when using the SB? If not, try changing the cable/input. Does the volume difference follow the cable/input. If so, then the system is not fixed :) Regards, an interested outside observer. -- Grahame ------------------------------------------------------------------------ Grahame's Profile: http://forums.slimdevices.com/member.php?userid=1200 View this thread: http://forums.slimdevices.com/showthread.php?t=38024 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
