: Fred, It sounds like you might be inputting to an amp input that requires a different microvoltage, i.e. a home stereo amp CD or tape input requires a higher signal (200mv.I think) than the QS puts out. Musical instrument amps usually have the correct input if it is geared for keyboards or something similar (50-75mv.) I got the same hum that you're experiencing with both a Roland kybd and the QS8. Try someone else's amp or PA system.
: Hope this helps. Paul

With my other synth (Roland) I never had any problems. Even if I hook my headphones direct in the QS8, the hum is audiable, and between my synths and my amp there's a mixer, and if I plug my headphones in the mixer, still a hum. I'ts got something to do with the powersupply (60 Hz is the local AC) or with grounding, but i don't know what. Direct next to the powersupply is the phones, this one has a lower hum than the L/R next to it, and the hum on the AUX L/R is lower than the one on the normal L/R.
When I'm playing it's distracting me... And for live use it could be a problem...
