| Re: sub hums if I turn on SPL meter
Ok, it was indeed a bad connection. The coacial input was to thick at the edge for the input on the RS spl meter (wich is kinda turned more inside the spl meter itself. But I took a nife and cut a piece of the edge away and now the distorting rumble is gone.
now only remains the problem with the soundcard calibration where the measured sweep seams to be to low (only 53 db fs). So I get that warning every time after the sweep.
