I did the same thing, I've got a preset named Helix Remote and use colors to identify things. I think that the decision not to let the Helix recall the PC presets via L6 is a mistake. I understand that having the Helix control the parameter (not all of them though) makes it almost 100% portable on every stage where you get a PC as a backline amp. You keep everything in your helix and your're set and you don't need to maintain both helix and PC presets. But for those who bring their personal PCs at gigs or simply play at home, recalling PC presets makes perfect sense and simplify things. Anyway the L6 integration is still buggy.

Leave it on. The soldi state power section of the powercab (or any other FRFR cab, PA speaker o studio monitor) is basically transparent and is there to make what you send in louder. What you want to hear is the full amp model amplified. Of course feel free to experiment.

I just want point out that the cab specs says 70Hz-20kHz neutral frequency response in Flat mode and that doesn't mean the cab goes down to 70hz only but that is liner(ized) from 70 hz to 20hz The cab goes clearly lower that 70. Between 40 and 50 there's a lot of stuff going on you can boost or cut effectively, meaning that the cab/speaker is able to reproduce those frequency with little effort. If you play bass having a sub is still a good idea since the E string is a 41Hz note and a lower B is a 31Hz note.

I finally used the 212 with the band and I'm very pleased. I tested several Irs I've loaded in the cab and sounded really good to me. I've added an eq with +3dB @ 80hZ to get a feel closer to a 4x12.

I still have to use the PC212 with the band at full volume, due to covid19, but in my experience you always loose some thump when going from 4x12 to 2x12 unless you go for XXL formats. There's no way to avoid that.

I 've bought a PC 212+ recently and I find the speaker mode really underwhelming, to be honest. In FRFR or IR mode the cab is really good but the modelled speakers don't sound good at all to me. I've always played the Helix with real cabs and the speaker mode of the PC 212 is not even close to what an actual 2x12 cab sounds like.

Does anybody knows what is the nominal headroom of inputs, outputs and send/returns? I'm new to the helix world still have to experiments with pedals in the fx loops but I was wondering, for example, how much can I boost with a clean boost in the fx loop before clipping the input side? Or, how much can I boost with an helix block at the end of the signal chain before clipping the output? Of course there's not a unique answer to this question one you start messing with volumes inside the helix because but I'm sure there's a nominal level (wich only line 6 knows). At the end I'm interested in an indication of the performance we may expect from the unit in the case it's used with 4 cable method with a tube amp, a situation where you might need to boost the front of your amp with and helix boost or a boost in on of the fx loops and need to boots at the end of your signal chain (again internally or with a pedal) for solos. I agree with those who are asking for some kind of meters for inputs and outputs.

HI everybody, first post here, I own a 2555x and the amp ext out of my helix works perfectly with the amp in a 4cm configuration. Before buyong the helix a couple of weeks ago, I've read this thread and was expecting a problem, but there's none. Everything is fine. The only "issue" I've had is ground loop noise I've solved with a passive ground loop killer between helix send and jubilee input.
