rickzjamm Posted December 12, 2013 Share Posted December 12, 2013 Does anybody know how I can get rid of an annoying "hum' coming from my PC3K7? I even notice a similar buzz from my Kurz SP4, is this a Kurz thang or something more dubious? And yes I had the sound man check the other instruments & did the ground lift ritual. What's up?

mate stubb Posted December 12, 2013 Share Posted December 12, 2013 Electrical buzz thru the speakers, or an acoustic hum you can hear without being plugged in to an amp? Moe --- Link to comment Share on other sites More sharing options...

bluzeyone Posted December 13, 2013 Share Posted December 13, 2013 Hi bluzeyone Hit me up via the form below: http://kurzweil.com/support/operational/ Thank you but I think rickzjamm is the cat with issues. One of these years I might be able to score a Kurz. "A good mix is subjective to one's cilia." http://hitnmiss.yolasite.com Link to comment Share on other sites More sharing options...
rickzjamm Posted December 13, 2013 Author Share Posted December 13, 2013 Bluzeyone, thanks for the great suggestion on the hum eliminator. I'm going to try it & also touch base with kurztech911 JB. The frequency of the hum is around a G3 & is consistent whether I'm using a DI or a Y cable ( L/R qrtr. inch to XLR male) & it's in the headphone outs too. I'm crossing my fingers the hum eliminator will do the trick. You don't know you're in the dark until you're in the light. Link to comment Share on other sites More sharing options...

mate stubb Posted December 13, 2013 Share Posted December 13, 2013 Y cable? As in shorting together the left and right stereo outputs of the board? Moe --- Link to comment Share on other sites More sharing options...
rickzjamm Posted December 13, 2013 Author Share Posted December 13, 2013 Left & right quarter inch cable (two male ends) go into a single XLR male, eliminating the need for a DI & getting a stereo out. Works great with everything else ( Nord & Roland; Roland L/R XLR outs are built into their board already - wish everybody else would do this) until I put it on the Kurz. then it's buzzy city!! Just wasn't sure if other people experience the same issue. I ordered the Hum Eliminator, will keep you posted. You don't know you're in the dark until you're in the light.

I-missRichardTee Posted December 13, 2013 Share Posted December 13, 2013 I've used them. They really work. http://m.guitarcenter.com/Item/Default.aspx?itemno=1371896&urx=1 I just started using a mixer with a PA.. not a ready made type PA, but one I have to plug a lot of stuff in.. 3 powered speakers, mixer, I am concerned about hum.. so far none.. but one of these days! Does this $85 device act as a hum eliminator for dumbies? I don't understand ground loops and whatever other things cause hum. Maybe you can start a thread on this topic?

bluzeyone Posted December 13, 2013 Share Posted December 13, 2013 Its pretty basic. Have to be for me to utilize! I was first introduced to it in 2000ish. It even covered them honky-tonks with poor power and beer signs infamous 60 cycle. My rig was clean, clean. Even when having to run a quarter inch a far distance(rare occasion but sometimes unavoidable) That was over ten years ago. I imagine they even are more effective now.

mate stubb Posted December 13, 2013 Share Posted December 13, 2013 Please elaborate. You are using 1/4" jacks coming out of the L and R outputs of your keyboard, and combining them into a male XLR, then plugging that into a balanced mic input on a PA board? If so, that's wrong.

You need a TRS to XLR adaptor cable (or 2 for L and R), that's it.

mate stubb Posted December 13, 2013 Share Posted December 13, 2013 So you are hooking your keyboard rig directly to the PA and getting a ground loop. That is what a direct box prevents. Moe --- Link to comment Share on other sites More sharing options...
rickzjamm Posted December 13, 2013 Author Share Posted December 13, 2013 I hooked it up to a DI as well & flipped the ground lift, no luck. The sound man's pretty knowledgeable, he tried several scenarios but the hum was relentless. I realize many factors can also come into play. Some good suggestions though... thanks.

rickzjamm Posted December 20, 2013 Author Share Posted December 20, 2013 Hum Fixed! Kurztech911 said that going stereo and the type of cable I was using was the problem. Solution;TRS 1/4 to XLR left mono worked lie a charm!! Thanks JB & all the good suggestions. You don't know you're in the dark until you're in the light.
