AlexKenivel Posted May 23, 2016 Share Posted May 23, 2016 I'll make this quick. I use a quarter-inch cable for my Alto and I plugged an XLR cable from the XLR out of my iPod to our PA system. From the PA system I got a very annoying buzzing sound that stopped when I took the quarter-inch cable out of the pod. Remembering now, I did not have the Alto turned on at the time. Could this be the source of the noise? Quote Link to comment Share on other sites More sharing options...
cclement Posted May 23, 2016 Share Posted May 23, 2016 Sounds like a ground/earth loop. Have you tried flipping the ground/earth switch on the Alto? Quote Link to comment Share on other sites More sharing options...
AlexKenivel Posted May 23, 2016 Author Share Posted May 23, 2016 I didn't. Like I said, the Alto want even on and I didn't really have time to mess with it. I'll check it out next week at practice. Quote Link to comment Share on other sites More sharing options...
DunedinDragon Posted May 23, 2016 Share Posted May 23, 2016 It might be possible it was related to the Alto being off. I know this happens occasionally with the XLR out from our bass player's rig if the amp isn't turned on. It clears up as soon as we turn on his amp.

napynap Posted May 24, 2016 Share Posted May 24, 2016 It might be possible it was related to the Alto being off. I know this happens occasionally with the XLR out from our bass player's rig if the amp isn't turned on. It clears up as soon as we turn on his amp. I use Alto TS110a for monitors, and I set up the PA for most of the venues I play. At a particular venue, I noticed a horrible buzz sound from the Alto that would not disappear from pressing it's ground button, or swapping XLR cables. However, when I turned the device that it was connected to ON, then the buzz completely went away. Clean sound. I think it has something to do with the electrical grounding at that location, but I cannot be sure. Quote Link to comment Share on other sites More sharing options...
guitarplaya2000 Posted May 24, 2016 Share Posted May 24, 2016 Are you sitting somewhere that could be adding interference? A power panel somewhere? I have the same issue with my JTV59 and HD500x. At church I had played at one end of the platform for awhile with no buzzing; just pure clean audio output. But when the music minister decided to rearrange the musicians, I've started picking up all kind of interference from a Leslie Cabinet. I'm about 3 ft. away from it, but apparently, my rig is sensitive enough to pick-up interference from the Leslie's components (amp, cone motors). Just moving another foot away had diminished the noise immensely. Quote Link to comment Share on other sites More sharing options...
