[sdiy] hum on the outputs

[Danjel van Tijn]

Hey guys,

I have an Ensoniq DP4+ and on one pair of the outputs (3+4) I have
this hum/buzz that seems to float in from time to time (but not the
headphone jacks or outputs +2). This will happen even without audio
sources plugged to the inputs and the fx on blank presets. What kind
of internal failure or problem would cause these symptoms? The buzz is
not all the time and when it does appear it seems to waver in volume.

Also, is the better forum for me to be posting questions about fixing
audio/studio gear? (gearslutz maybe?)

cheers,
Danjel
