  1. Have you tried listening to your FRFR in different rooms? Small offices have notoriously bad acoustics - specifically, huge swings in low/low mid frequencies depending on your exact location in the room, which can cause your tone to go from muddy to thin just by moving a few feet. I can tell you this from experience, as it’s the exact reason I have to mix on headphones at my house. I would suggest setting up in a larger room, if possible, and listening from at least 6 feet away as others have mentioned. This should give you a much better representation of what the tone will sound like live (assuming that is your goal - if not, this may not help much). I would also caution that most headphones are not particularly “flat.” So even if your FRFR sounds dramatically different in a larger room, it probably still won’t sound exactly like the tone you’re getting in your headphones. This is where the global EQ can be very handy.
  2. Looking at that monitor station, it appears that the 1/4” inputs are stereo TRS. That means they aren’t balanced, so there’s no reason to use a TRS cable unless you want a stereo signal. If you want a stereo guitar signal in your ears, use a TRS cable from your Helix’s headphone jack to one of those 1/4” inputs and make sure the input is set to “stereo”. Note that you can’t get stereo over TRS (to my knowledge) from the Helix’s main 1/4” outputs - you’ll have to use the headphone jack. If you want mono in your ears, use a regular instrument cable (or a TRS cable, doesn’t really matter in this case) from the main 1/4” output on the Helix to one of the 1/4” inputs on the Rolls, and make sure the input switch is set to “mono”. Again - I would not suggest plugging a regular TS instrument cable into the headphone output. Either way you aren’t getting a balanced signal, so the distance from the Helix to the Rolls doesn’t really matter. Edit: Just realized you said HX Stomp, not Helix. But the same principle should apply.
  3. Sounds like your amp’s bypass assign got inadvertently set to either EXP Toe, or one of the EXP Pedals. Select your amp block, press the menu button, and click bypass assign. “Switch” should be set to “None”.
  4. It’s not clear to me whether OP’s problem is solved or not, but one thing to remember with Helix is that you can do some pretty creative (albeit, tedious) routing with the FX sends/returns and some patch cables. Example: Ping pong delay on path 1A or 1B. Make the last block of that chain a stereo FX send, using Send 1/2. Turn the “Dry Thru” all the way down. Using 1/4” patch cables, patch Send 1 to Return 1 and patch Send 2 to Return 2. Place mono FX return blocks on path 2A (Return 1) and 2B (Return 2). Set both “Mix” controls to 100%. Now you have independent mono paths for the left and right channels, as long as you make sure to hard pan them left/right in the final merge block. It’s not exactly an elegant solution and it takes up three blocks - though you can theoretically save one block if you use the 1/4” OUTPUTS instead of sends on the first path. All of that said, you can really expand the signal routing capabilities beyond what’s allowed in the software by using the FX loops and patch cables. Another example would be if you need more than two sets of parallel paths.
  5. With those XLR/TRS combi jacks it really doesn’t matter which connection you use. The TRS and XLR parts of the jack are wired in parallel so they are electrically equivalent. As mentioned previously, going XLR from the Helix will give you a balanced connection, while 1/4†will not. Whether you need a balanced connection depends on your environment and the length of cable run, but in a studio situation it probably won’t make much difference. If it were me, I would probably just use XLR cables. If you do this, make sure the XLR outputs are set to LINE level (not MIC level) in your global settings. If you choose to use the 1/4†outputs instead, you can use a regular instrument cable. No need for 1/4†TRS cables since the Helix 1/4†outputs are unbalanced anyway. That being said, if you DO use 1/4†TRS cables it won’t create any problems. Since the ring and sleeve will be common at the Helix-end of the connection it will basically be the electrical equivalent of a 1/4†TS connection. Again, if you use the 1/4†outputs make sure they are set to LINE level (not INSTRUMENT level) in your global settings. If you’re curious about balanced vs. unbalanced connections you can find some pretty good, detailed explanations here: https://www.presonus.com/learn/technical-articles/Balanced-Unbalanced Typically connections between balanced an unbalanced hardware only become problematic when connecting a balanced OUTPUT to an unbalanced INPUT (the opposite of your situation).
  6. Ah OK I may have missed that. Have you tried using the Helix 1/4†output (instrument level obviously) instead of the FX send? Just curious if it makes a difference. Since it sounds like we’ve narrowed it down to the input side, the other thing you may try is adjusting the guitar-in impedance. It defaults to auto but you may find better results at a fixed value.
  7. I hear what you’re saying about the level controls being in the digital domain, but consider a couple of possibilities: 1. The noise is occuring in the head’s preamp but is being amplified by the Helix in effects loop. In this case, reducing the output level of Helix would bring that noise back to normal levels. 2. The noise is coming from Helix’s A/D and D/A converters. Using 4CM you are going A/D or D/A four times. Three of these occur before the output level control and would be reduced by turning it down. In reality it could very well be a combination of both. If you’re getting any power tube saturation you would expect any level increase to change the amount of low-level noise more than the playing volume. If there’s enough added gain to affect your tone, it’s likely more than enough to noticeably raise the noise floor. One other thing that may help locate the source is trying to isolate it to either the guitar->Helix->preamp or FX send->Helix->power amp sections. Do you experience the same noise with: - Guitar -> Helix -> Send 1 to amp input, but amplifier FX loop bypassed (no 4CM)? - Guitar -> straight to amp input -> amplifier FX send to Helix Return 1 -> Helix 1/4†output to amplifier FX return? If you get noise separately with Helix only on the input side of the amp AND with Helix only in the FX loop then it seems more likely to be converter noise. Not an issue I’ve encountered with my Dual Rec but maybe you got a lemon.. If you only get the noise with Helix in the FX loop it seems more likely to be a level issue. EDIT: It sounds like you have tried level matching with and without the Helix. Which level(s) have you been using to accomplish this? I’ve found it much easier to make precise level adjustments within the output block (volume knob unassigned) than doing it with the knob. It’s just easier to keep replicate small adjustments that way and see just how much you are adding or attenuating.
  8. This might be a dumb question, but have you completely ruled out a level increase through the helix as the culprit? There are two reasons I ask: 1. If it is a 3 dB increase, I would consider that to be quite a bit and would expect your noise floor to increase notably. 2. I haven’t been able to find the input/output specs for the inputs/sends/returns/outputs so it’s possible that it’s not unity gain going from guitar in -> send 1 or from return 1 -> 1/4†out. I’m sure someone here can clarify... Have you tried actually measuring the outputs to rule this out? If you build amplifiers I’m sure you have the tools. Just need a signal generator of some sort and a multimeter: 1. Measure signal generator output voltage at low (instrument) level 2. Connect signal generator to Helix input, measure Helix Send 1 output voltage. Is there an increase? (1 and 2 only work if you can get an instrument level signal.. not likely with a phone app but maybe a dedicated generator?) 3. Measure signal generator output voltage at line level 4. Connect signal generator to Helix Return 1, measure 1/4†output voltage. Is there an increase? If there’s an increase in level across the Helix then you know that’s your culprit and you can adjust either the send, return, or 1/4†output levels accordingly. Admittedly this is a pretty silly thing to have to do, which may not be necessary if Helix had meters... If it were me I would probably just try turning the return and/or output levels down and see if I could match the tone. I’ve never been able to hook up rack gear in an FX loop at “unity†successfully without adjusting either my head’s send/return levels or the levels on the rack gear... maybe you’ve had better luck than me. Long story short: while there may be some noise from the converters/preamps I would expect it to appear much more drastic if there’s any gain not being accounted for across the Helix or your FX loop. And if there is gain across the Helix, turning your outputs back down should reduce that noise floor and bring you back to unity.

    Helix FAQ

    So, I tried this before from the footswitch assign with no luck. Just tried from the command center after adding a MIDI command and still no luck. Even after I assigned a label it would continue to display "EXP1 EXP2", but I figured it out. Turns out that you HAVE to change the default label that appears under "customize" or it doesn't display. For example, if I'm using the Teardrop 310 wah model and it's assigned footswitch is EXP Toe, I press "customize" the default label is "Teardrop 310". If I then press "OK" the scribble strip still reads "EXP1 EXP2". However, if I change the label at all, from "Teardrop 310" to "wah" or even "Teardrop" for example, it shows up on the scribble strip. Just a little insight for anyone else that ran into this.

    Apologies is this has already been answered: is it possible to change the "EXP1/EXP2" scribble strip display? I do see an option for customizing the "toe switch" label.. But I don't see that it shows up on an LCD anywhere when I change it.
  11. So I just added an IdeaScale submission: "Expanded Display for EQ and Compression Blocks" http://line6.ideascale.com/a/dtd/Expanded-Display-for-EQ-and-Compression-Blocks/787679-23508 Basically, I would really like to have a display that shows the EQ and compression curves, and I believe it would be relatively simple to implement as a pop-up attached to one of the control knobs for the block. Turns out when you're coming from Pro Tools it's hard to set a parametric EQ without seeing the curve... can't really visualize the Q setting. As for the compressors, if nothing else it would be nice to have a gain reduction meter. I get that if you're only using your compressor for tone, maybe it's easy to set by ear. But when I'm using it for volume leveling it would be much easier with a meter. Again, coming from Pro Tools and digital mixers. Lastly, if nothing else changes, the Global EQ should have a visible curve. It's literally the only thing on the screen and all that LCD space is just wasted.
