joeduf Posted February 27, 2017 Share Posted February 27, 2017 Hello to all, Rather than tack on to an existing thread I would like to start something new. First off I would like to say I love my Helix. I've been a huge Line 6 fan since the original red kidney bean POD. Now, so we are all on the same page here, I'm using the latest available Helix Rack firmware v2.12 and the Factory 1 Set List patch 02C Brit 2204. I can hear considerable noise, at least compared to other, lower gain / cleaner type sounds, just by plugging in a guitar. Explainable to a degree because that factory patch has no noise gate of any kind. However, when the guitar is plugged in and volume on guitar, and helix, and helix patch volume are all up, the noise volume gets worse depending on which direction I'm am facing while holding the guitar (touching strings / metal). As if there is some environmental and highly directional interference...coming from a wall (!). It is not relative to my position or orientation with the Helix itself. No other computers / electronics, or florescent lights of any kind powered on nearby. I can relocate my Helix rack, power amp, cabinet, etc. But if, for example I point true north the noise gets unbearably loud. If I rotate in position the noise level varies and sometimes disappears altogether. I've tried all new cables: guitar patch cables, XLR cables from Helix to power amp, speaker cables from power amp to 4x12. I've tried multiple guitars with all types of pick-ups, Multiple power amps. Tried the ground lift switch on the back of the Helix. I've tried separating the power cables to different circuits (Helix and power amp), tried all to the same circuit with, and without my Furman power conditioner in line. Tried lifting the ground on the power amp with a three to two prong converter. Nothing helps reduce the noise or change the behavior. Again only for certain higher gain sounds. I understand higher gain raises the noise floor. However I have real 2205, close to the amp modeled in that patch, and the noise on the real amp is no where near the level heard on the Helix. So my question is, what exactly is the source of this problem and how do I keep my higher gain Helix patches from bleeding too much noise without clamping the noise gate down to the point where notes are cutoff prematurely? NOTE: The phenomenon happens to me in multiple venues / locations but not everywhere, hence why I believe it to be environmental. Looking for electronic gurus or people who've most likely dealt with and solved this type of problem this in past. Please help if you can. looking for a solution or at least some ideas, things to try, etc. Quote Link to comment Share on other sites More sharing options...
