isak531 Posted March 14, 2019 Share Posted March 14, 2019 So I've just recently started using my Helix floor in 4CM with my Marshall Mini Silver Jubilee 2525H and Marshall cab. However there are two things I cannot figure out. How do I control my external pedals and change channels within the amp using my Helix (if at all possible?) The footswitch control changing the channel on my amp is a one sleeve 1/4" cable, theres no midi on my amp. Also is it possible to keep my Helix connected to my PC via USB without playing the sound on my PC through my Marshall cab? Hope someone will be willing to help me.. Cheers!

rd2rk Posted March 14, 2019 Share Posted March 14, 2019 Windows Control Panel/Sound - set the default Playback Device to the computer's soundcard. Connect a 1/4" TS cable (any old guitar cable should work) from the Ext Amp 1/2 jack on the back of your Helix to the Footswitch jack on your Marshall. You may have to set the TS/ST/TRS setting in Command Center. Quote Link to comment Share on other sites More sharing options...
isak531 Posted March 14, 2019 Author Share Posted March 14, 2019 Sadly my PCs soundcard doesnt have any output which lets me connect it to my studio monitors, so it has to go through Helix first, is this not possible? Quote Link to comment Share on other sites More sharing options...
rd2rk Posted March 14, 2019 Share Posted March 14, 2019 What kind of computer are you using that doesn't have an audio out? Headphone out? You can only use the tiny little onboard speakers? If that's really the case, you need a new computer! You could try GLOBAL SETTINGS-INS/OUTS-USB 1/2 Destination - set it to XLR so that it's not coming out the 1/4" that you're using for the 4cm wiring.

Well its a gaming PC which is not THAT old though Ive upgraded CPU etc gradually, the motherboard only has those small headphone outs kind of jack, not sure what theyre called.. Will try the global setting thing, thanks! Using snapshots to enable/disable external pedals, is that done in the Command center? Same as the amp channel switching?

isak531 Posted March 15, 2019 Author Share Posted March 15, 2019 The global setting fixed the PC audio issue, thanks! Managed to get the amp switching to work however A LOT of noise comes when I activate the lead channel... how do I fix that? Played around with the FX loops outs to instrument/line level but that didnt solve it Quote Link to comment Share on other sites More sharing options...

Yep, that's the one that you use when you do the assignment I described in my first response. Using a small mixer (I use a Behringer Xenyx502 - $50) you can get all your levels matched nicely. As for the noise, what kind of noise? Hum? This is a well known problem. A hum eliminator like this might help: https://smile.amazon.com/Pyle-Eliminator-Destroyer-2-Channel-PHE300/dp/B00BARTW3I/ref=sr_1_3?crid=1OT8WO6PZCMET&keywords=hum+eliminator+audio&qid=1552663606&s=electronics&sprefix=hum+%2Caps%2C172&sr=1-3-catcorr Do a search here and on the Helix thread over at TGP (Gearpage) for "4cm hum". There could be other helpful suggestions. Quote Link to comment Share on other sites More sharing options...
