yalyari Posted October 17, 2022 Share Posted October 17, 2022 Is there any difference expected soundwise if I plug my guitar to L/Mono input vs. Right input? My HX Stomp signal chain is mono. I'm planning to use this right input as a backup in case my wireless unit connected to L/Mono fails. It seems working from my quick test. There was subtle difference but I guess it's buffered (via wireless unit) vs. unbuffered. I want to make sure I'm not doing something st*p*d.

brue58ski Posted October 17, 2022 Share Posted October 17, 2022 According to the manual both inputs are always active and they are both on all the time. No description about the dfference (if any) whether both inputs have something plugged in them or just one input does. Quote Link to comment Share on other sites More sharing options...
rd2rk Posted October 17, 2022 Share Posted October 17, 2022 Starting with a New Preset, the L/Mono Input is on BOTH sides of the Stereo Buss. The RIGHT Input is ONLY on the RIGHT side. If you add a STEREO FX Block the signal stays on the RIGHT side. As soon as you add a MONO FX Block, for instance, an amp, the signal is sent to both sides. 1 1 Quote Link to comment Share on other sites More sharing options...
yalyari Posted October 18, 2022 Author Share Posted October 18, 2022 Thanks @rd2rk. I just tested it, everything is as you explained. Quote Link to comment Share on other sites More sharing options...

Just my own curiosity. So if I plug something into the right side only, it will only appear on the right side of the path until/unless a mono block is used? But if you're plugged into only the L/Mono, it will appear on both the Left and Right sides? Quote Link to comment Share on other sites More sharing options...

Yes, that's what I've found from quick experiment yesterday. @rd2rk, so L/Mono goes to both L and R by default. Does it go to L only if I put stereo block at the beginning of the chain? I forgot to test this scenario. Quote Link to comment Share on other sites More sharing options...

Being able to plug separate instruments into the two inputs and use panning to keep them separate allows you to have two completely separate signal chains for two separate instruments. Of course, DSP is a problem, but careful choice of amps and FX makes a duo performance at least possible. Here's a demo preset for anyone who wants to try it. Plug a bass in the RIGHT Input and a Guitar in the LEFT. You get bass on the RIGHT and guitar on the LEFT. L_R Input Test.hlx Quote Link to comment Share on other sites More sharing options...

Does it go to L only if I put stereo block at the beginning of the chain? I forgot to test this scenario. No. Plugging into L only sends the signal to both L/R channels, so a stereo block will be - stereo! Plugging into R only the signal remains in the R channel through a stereo block. Simple way to think about it - use L/Mono to send one instrument to two signal chains, all panning centered. This is how to do a dual amp rig. Use an A/B split with a FS assigned to the Split to use one rig at a time, or a Y split to use both at once. BOTH paths will be stereo after the amp/cab blocks if you use stereo FX. A dual cab block after the stereo FX keeps it stereo, but DSP becomes an issue. Two instruments to two signal chains - keep Path A (LEFT Input) panned LEFT and Path B (RIGHT Input) panned right. Use ONLY mono FX. I haven't tried it, but if you have two separate stereo systems you should be able to separate the paths and use stereo FX in each, sending the L/R Main Outputs to one system and the 3/4 Sends to the other. Again, DSP is the main issue. Quote Link to comment Share on other sites More sharing options...
theElevators Posted October 18, 2022 Share Posted October 18, 2022 If you are sending both channels: left and right, then when combined, they will be hotter, and may drive amps more than if you only send one side.... At least that's how it works in the real world. Quote Link to comment Share on other sites More sharing options...

Then to maintain L/R separation for stereo input, should I put split block to route L/Mono to L only? This is somewhat counter-intuitive for keyboard player which may feed stereo input to Stomp.

yalyari Posted October 18, 2022 Author Share Posted October 18, 2022 My original use case was about plugging single guitar cable to L/Mono or R, which has been well answered by you. Thanks a lot! Regarding plugging stereo cable into L/Mono AND R is just out of curiosity. I just want to know how HX Stomp behaves if I plug in stereo instrument (keyboard with L and R outputs, for example) to both L/Mono and R. If I want to maintain stereo separation (L/Mono input to L output, R input to R output), then from your explanation I need to put splitter to direct L/Mono to L only. Otherwise L/Mono goes to both L and R output, messes up the stereo separation. Is my understanding correct? Quote Link to comment Share on other sites More sharing options...
rd2rk Posted October 18, 2022 Share Posted October 18, 2022 All Paths in the Helix products are stereo. As long as you use all stereo FX you have stereo separation. If you use BOTH inputs for a stereo instrument you do not need to do anything special, It's only if you DON'T use BOTH inputs that L/Mono goes to both stereo channels. IOW - when both inputs are connected, LEFT is LEFT and RIGHT is RIGHT. 2 Quote Link to comment Share on other sites More sharing options...
