  1. No it isn't. There is a claim that need to be backed up by an evidence. I am not really sure if he compared the "pad on wow" with other options. No I didn't. I asked if we can think of a replicable by anybody else method to test his claim. I don't see anything insulting there. Why? If there is any evidence maybe this is a time to change mind. I do not have any opinion about superiority of one method of attenuating signal over another. No. What I feel is you are dumping me, not me dumping the OP but I can be wrong. I would gladly make an experiment myself, but I am away from my hardware Helix and I hear no benefit of attenuating guitar signal before A/D converter by any means with Helix Native and my audio interface. This is why I ask if we can can settle the experiment conditions tossing out the two methods which are hardly comparable because of lack of dB attenuation value. If somebody could upload two direct tracks, one with pad on and second with no pad, digitally attenuated after to the same level (to make it blind testable) I and anybody else on this forum could test it with any modeller and post one's opinion. What is wrong with that approach?
  2. Can you give any example to back up your claim or you just feel I am evil? What is so wrong in demonstrating the input pad is superior to post A/D attenuation if this is demonstrable? If it's not, what is the point of talking about it? Any opinion is valid then, isn't it?
  3. About magic feelings that can not be demonstrated?
  4. They are not transparent in case of passive pickups, they load them and overal input impedance is higher. Neither a pad before AD converter is with a respect to S/N ratio. It is worse by attenuation amount. But maybe it is worh it if somebody can actually demonstrate is sounds better. It shouldn't be hard to do. hahahaha If you tell me your Helix sounds better when you play under a ultraviolet lamp but it works only on Sundays at your church if I believe in Jesus walkin on the water, it is hardly falsifable for me. :)
  5. Right. So how to show and let feel it to other people that getting that attenuation before AD converter is better than attenuation after AD or is better than setting a gain lower? I am not. I want to feel what you feel. Please teach me. I have given four colours of attenuation to consider and test. Neither is black or wite nor right or wrong. Again. I really want to feel and test it or at least to hear somebody else demonstration. Why?
  6. OK. Your claim is falsifiable at least at "feel" level. You are right - there is no dB scale on dirtboxes and amp gain so full comparision would be tuff. For further investigation let's reduce it to the two states numbered 1 and 2. What is your proposed experiment and how to prepare blind tests? Is the pad 5 or 6dB and how can we determine that? A generator and a DAW meter? Or maybe you have your clips ready and you want to attach them to forum readers to choose which sounds better?
  7. OK. So how do you compare those four states: 1. "Input pad on" 2. "6dB volume down" after AD converter 3. "Lower dirt box gain or volume" before preamp/amp block 4. "Lower amp gain" (when no dirtboxes are used) to claim the first is superior?
  8. The difference between what?
  9. How do you know what guys at Line 6 are working on? Any leakage on The Gear Page?
  10. You can also use 48kHz only Class Compliant mode to keep the latency at a playable level or use your audio interface direct monitoring.
  11. Yes, aggretating devices but the Round Trip Latency would be the higher of the aggregated interfaces. Quite high in case of the multi sample rate driver.

  13. Those guys at Line 6 have so deep knowledge to be found all over the net but L6 manuals, knowledge base, FAQ, specs, charts! ;)
  14. Nobody (except Ben Adrian and a few guys at L6) knows how Hx tone stacks are modeled. Real AC30 hever had any tone stack on the "normal" channel, nor presence on the power amp.
  15. Not at all, because my case was different. You have some trace of evidence based on your case but the data is at Line 6 Customer Support. They recommend you to get a cable which works properly with your host and they probably know you will instead of sending them several replacement cables back.
  16. I have contacted Line 6 about my issue with the original USB cable (audio was crackling and Hx Edit disconecting after 2min.). They responded with some gauge considerations. What I understood the perfect USB cable is that working with Helix and an attached USB host. They would replace it with whatever they have in stock anyway, so I gave up. "This depends on the used setup (USB port, chipsets etc) sometimes different diameters work better on some systems, but there's no general rule : USB cable diameters are (hidden in the code printed on your cable) AWG 24: 0.511 mm AWG 28: 0.321 mm if it works better with another cable, we recommend using that one Best regards, Technical Support Line 6 Support Europe"
  17. Where was it documented? Is there any avialiable documentation what MIDI commands Helix is supposed to transmit, receive and filter?
  18. Or maybe you did not change the time base from ms to bpm?
  19. I have just checked Hx Native. I can not replicate your issue. If you double check (differents modes and tempo) and somebody confirms please report it as a bug.
  20. 1. If the amp is modelled right, so it's presence have to be modelled right. The comparision has to be made with respect to real amps, not to amp recordings. 2. No amp comes with a presence dialed in. Maybe model default settings. 3. No decent commercial IR should be made on any tube amp with non flat frequency response or presence dialed in. 4. The presence in case of tube amps is usually EQ in a power amp feedback loop, some amps have no presence, presence eq works different in different amps. So, simply no.

    Output Questions

    Why don't you give him your direct signal and Helix if he knows how you should sound and sit in the mix? Oh sorry, it does not solve your problem cause your home heaphone sound will be different and panned. :(
  22. Some minor changes were made to the 3.0 manual. Not many, but thank you Digital Igloo. https://line6.com/data/6/0a020a4112b165fb6a3fe41663/application/pdf/Helix 3.0 Owner's Manual - Rev E - English .pdf What I miss is DSP allocation values and latency of DSP blocks. Page 9 29. MIDI IN, OUT/THRU Connect Helix to your MIDI gear for sending and receiving program changes, continuous controllers, and other MIDI messages. Correction: 29. MIDI IN, OUT/THRU Connect Helix to your MIDI gear for sending and receiving program changes, continuous controllers, and other MIDI messages. Please be aware that THRU operation filters some MIDI data. Please refer to the Helix MIDI Implementation Chart. Specifications is still missing. That can be helpful: Greetings for all Line 6 employees for a new year!
  23. Oh really? During that "mathematical operation" noise is added because it masks aliasing noise which is worse. Albeit this is not a reason normalisation makes any sense working in 24 bit integer of 32 floating point enviroment. The reason is some guys are familiar with "under a celiling" recording. I was too and changed my mind. Leaving 10-12dB of peak headroom is much safer and devoting some SN ratio is worth it.
  24. Not true. SN ratio is affected because noise is recorded and remain constant. If you leave 10dB of peak headroom SN ratio of AD converted signal will be lower by 10dB cause it is constant.
