Helix Talk

Might not be related to phantom power at all, he's talking about the XLR ground lead, sometimes there is enough potential between two remote equipment ground points to cause enough current on the cable shield and generate power on the highest resistance points on that path like very thin PCB traces or loose contacts, think shorting a 9v battery with a thin wire, the wire will heat up or even melt if it's thin enough.
Most often there isn't big enough ground potential difference to cause damage, or at least there shouldn't be if everything is in order with the equipment and the building's electrical system.

I'm highly doubtful that phantom power led to the vaporization of the trace. It would have to involve a faulty phantom power providing device to allow for high enough currents AND a signal lead would have to shorted to ground.:

Edit: If a TS to XLR cable is used with the 1/4" OUTs this increases the risk of damage. Still a defective phantom power providing device is needed to damage the Helix.

A transient current when connecting two grounds (plugging in an XLR cable or disabling GND lift) can be high enough be a cause with thin enough traces.

Also, a difference in ground potential is what causes the microphone voltage tingle/shock on the lips, it means there's at least 10v (or more) difference between the mixer/microphone and your guitar/amp/modeler grounds, otherwise you would not feel the voltage tingle on the lips.
This usually doesn't happen if both equipment ends have good earth connections.
 
I just want to say I really appreciate that Line 6 are making these videos and not relying completely on youtube advertisers.
Maybe some official videos of the sound design team comparing the real amp vs the model? That would be insane!; and will clean a lot of the old stigma surrounding Line 6 modeling.
 
Has Line 6 always been using schematic/spice based modeling?

Would be nice to have @Digital Igloo or @benadrian to confirm but, IIRC, Helix is not quite component-level modelling. They do model individual subsections of circuits, and their interactions with each other though.

+100. I particularly enjoy Paul Hindmarsh's videos on new Helix features (and products). That guy is a great demonstrator, and a monster player too.

I’m partial to this stuff anyway, but I’d love to see more of Line 6’s reference amps. I’m sure the models are dead on but it’s a cool way to validate it and learn more about what the real amp is actually like. I quite like how JHS’s youtube channel will compare stuff side by side with some historical context without being overly scientific

Having some visual and background of the real world counterpart makes it more fun to use than just staring at a list of amp names.
 
Maybe it's cheaper to pay an advertuber than to make an official video?
Probably, and it reaches a wider pool of people, and it doesn’t have to necessarily meet the same production standards and fact checking as an official video would. Probably not the best use of staff time either….

Did Line 6 provide some A/B’s around the release of Helix? I think they probably would have got more attention with video footage and a bit more hype/focus around it

Either way, Line 6 have an awesome museum of gear that is a pretty valuable advertising resource in itself (even if it’s not directly advertising any set product, it draws customers in, builds rapport, shows something unique etc)

Eh, that’s component modeling though. AFAICT it’s just a term used to denote that a circuit was modeled using a white-box approach (nodal analysis, WDF, state-space, etc.) as opposed to a black/grey box approach. The granularity just depends on how much compute you have.

Line 6 Helix's webpage used to include an A/B test. It showed the aggregated results, and it was basically 50/50. Not sure why they got rid of it, the marketing department's decision I suppose.

Not disagreeing with you, just nothing this is not quite SPICE, which usually means going down to physical component level. We routinely used to run SPICE simulations modelling individual transistors back in the day.

Everything sounds like a Marshall.
Everything tastes like chicken.
We've hit rock bottom, not even James Cameron can raise the bar from such depths.
