robberns Posted January 18, 2018 Share Posted January 18, 2018 Curious if anyone out there in Helix land has had success getting the Helix to channel switch a Splawn amp. I have a Splawn SuperSport and can change the channels with the Splawn footswitch no problem. When I plug a TRS cable into the Helix and then into the "B" jack (which changes amp channels via the Tip if a TRS cable), I get a loud hum and no channel switching. On top of that, I find the Helix manual to be a bit dodgy about how to set up a footswitch to change amp channels externally. Any help would be appreciated!

Have you confirmed your Helix configuration settings for the Ext Amp output in Global Settings? Quote Link to comment Share on other sites More sharing options...
robberns Posted January 19, 2018 Author Share Posted January 19, 2018 Not sure what you mean, there is no place to set any Ext Amp settings under Global Settings that I can see. Quote Link to comment Share on other sites More sharing options...

It's in the input/output settings. You may have the page over to see it. If can be configured to tip, ring, etc. Quote Link to comment Share on other sites More sharing options...
robberns Posted January 19, 2018 Author Share Posted January 19, 2018 I think you mean Command Settings. I have tried all 3 settings for tip-to-sleeve, ring-to-sleeve, and both. No difference. What I am hearing sounds like a ground loop. It may be the way the jacks are wired in the amp. I have a HumX unit I can try lifting the ground with. Just wondering if there were any users out there doing channel switching on a Splawn. Quote Link to comment Share on other sites More sharing options...
