vinnykeenan Posted March 19, 2018 Share Posted March 19, 2018 Hi Guys, I'm a relatively new Helix user/owner and although I am delighted with it, I have found an issue that I cant seem to resolve and wondered if there were any tips or upgrades to help. My Issue - As well as using the amp models straight into the desk, I plan on using my Helix as an FX board with my Marshall JVM. I have hooked it all up via the 4 Cable Method, which is fine, but there does seem to be a lot of hum. I have changed cables and set up a Noise Suppressor at the end of the FX chain but I feel it cuts the natural sound of what is a very quiet amp. I haven't used it live yet as it could be an issue. Does anyone have any answers to this..... Thanks for reading, Vinny@V.K.G. Quote Link to comment Share on other sites More sharing options...
pianoguyy Posted March 20, 2018 Share Posted March 20, 2018 The first thing we need to determine is ---- what kind of hum are you talking about. Some hum is there on purpose. Some hum is a sign of electrical issues. Some hum is a bad thing. Some hum is a good thing. Quote Link to comment Share on other sites More sharing options...
vinnykeenan Posted March 20, 2018 Author Share Posted March 20, 2018 Thanks for the reply, I'm using the helix with my JVM head. The JVM is a very quiet amp considering it can be high gain. What I have found is that as soon as I plug in the Helix using 4CM there is a hum. I changed cables but its still there. The only way to get rid of it or lessen it is by using the Noise Gate on the Helix, but set pretty high, which then means it cuts off the signal quicker that I would like.

jud1433 Posted March 25, 2018 Share Posted March 25, 2018 I use my helix in 4cm with my engl which is high gain but i place 2 noise gate blocks in the chain leave them stock settings (id have to recheck where i placed them lol) i dont use the input gate and my rig is totaly silent and my sound is unaffected so may be worth giving it a go and put 1 straight after the send/return block and move the second one around but ill check my signal chain when i get chance and reply...hope this helps.

TRENDKILLCFH333 Posted March 27, 2018 Share Posted March 27, 2018 I have the same issue and also read that an Ebtech Hum Eliminator in the FX Loop will work. I'm going to try mine out in that position tonight. I do put a noise gate in the last position of my front of amp block and also in the last position in the FX loop. Both help a little, but I think the issue is a ground loop hum. I have a JVM 410 as well - it's a beast of an amp!!! Quote Link to comment Share on other sites More sharing options...

jpdennis Posted March 29, 2018 Share Posted March 29, 2018 Due to the various venues and their "individually unique" power feeds this is an issue that has plagued me no matter what amp I use even when using my Monster 3500 exclusively for all power connections. I have the Ebtech Hum Eliminator and it works great. I have used Behringer and Pyle as well with success. Dennis Quote Link to comment Share on other sites More sharing options...
vinnykeenan Posted April 18, 2018 Author Share Posted April 18, 2018 Hi Guys, Thanks for all the replies and help with this one. I did get it sussed out by adding a Noise Gate just before the Send and Return, then another at the end of the line, just before the output and it works. Vinny.
