XEQT 0 Posted November 26, 2018 Hi ! Do i need to use grounded (erathed) sockets with Helix or will it work without it any way. I get a strange signal in it. If I put a guitar in it gives a high noise problem. If i connect it to my soundcard it works perfect. No high noise or anything. Both have grounded cables input but there is no ground connected to them so is that whats making the noise or is the cpu fried in my rack unit ?? // Roberth Quote Share this post Link to post Share on other sites
njglover 75 Posted November 28, 2018 The Helix itself, at least the Helix Floor and Helix Rack, use 3-prong power plugs (at least here in the US), so it should be grounded just by plugging it into the wall unless you are using an adapter to remove the ground.

Singletone 0 Posted November 30, 2018 It may be RF (radio waves), I have found that if I leave my cell phone in my front pants pocket it causes odd popping noise in one of my instruments. Quote Share this post Link to post Share on other sites
jbuhajla 325 Posted November 30, 2018 Also if you get your instrument close to a computer/laptop or external power supplies, the instrument pickups will pick up high frequency noise. Quote Share this post Link to post Share on other sites
