Is Helix all digital?

Recommended Posts

For whatever reason I thought that some of the effects had actual analog circuits built into the Helix, thought it was mostly for some of the distortions/od's.  But I can't find any info to support that claim.

 

So is it all digital?  I don't care either way, I love my helix.  I just want to know for a discussion I am part of.

I think it's all digital, they did model analogue components like the lamp in a Univibe but that still makes it digital.

All except for the little hamster wheel that cranks up when you turn it on...

 

Ooooops I forgot about him. I haven't fed him in awhile either. I hope he's OK.

...mine is a prototype that uses a ferret. I sort of wish I had the hamster model.

Rumor has it that the 2.7 firmware will include a squirrel upgrade...get your acorns now before the price spikes.

I suppose if you want some anologue you could run something like the Laney Pulse IRT in one of the loops. It is no hamster or ferret(which ends up stealing anything shiny(never trusted that model)) but you know.

Hummm, I coulda swore I changed out the standard 12AX7's in mine with GrooveTubes" a year or so ago....

As long as that new squirrel has a tuner... Otherwise, I'll just wait for Helix 2 next Winter Namm ; P.

He's got an A440 tuning fork strapped to his head. Don't tell the ASPCA...;)

It just so happens that the Helix is only MOSTLY digital. There's a big difference between mostly digital and all digital. Mostly digital is slightly analog. With all digital, well, with all digital there's usually only one thing you can do...

Go through his pockets and look for loose 1's and 0's...;)

There are D/A and A/D convertors so we know there is at least a bit of digital to analog and vice versa if for no other purpose then to convert the input and output. Anything else analog?

you betcha. With regards to the OP's original question, the main analog stuff that matters is the analog input connectors/circuitry, power supply, A/D circuitry, D/A circuitry, and analog output  connectors/circuitry. But ...... the magic where the tone and effects are created is digital. Today's DSP circuitry is getting really good (fast, clean, high resolution) at modeling analog stuff (amps, stomp boxes, etc) — especially in the hands of good software engineers.

power supply

I'd like to nitpick here: Why the PSU? If anything, I'd call a switching mode power supply digital because of its hard switching characteristic and PWM controlled action.

 

As for the OPs question: No, there is no analog part involved in the Helix' effects. I'd be reluctant to specifically mention the input/output circuitry: Of course it has to be analog. There's also no such thing as "digital impedance" (aside from just using a cheap high-cut filter), so that part must be analog as well. Though it's of course a noteworthy feature to have it switchable in the Helix.

....you say potatoes I say potatoes. I think we've answered the OP's question. Besides, he seems to have left the room!

 

¯\_(ツ)_/¯

The TC Electronic Nova was digital with analog drives.
