Is Helix Stadium full 100V–240V multi-voltage? Can I use 220V on all production batches?

Hi everyone,

I have a quick question regarding the power supply specifications for the Helix Floor unit.

I am planning to use it in a country with a 220V / 60Hz power system (South Korea). I know that Helix units generally feature an internal auto-sensing switching power supply, but I’ve seen some conflicting information online—a few sellers listing their units as "110V only" or mentioning that a step-down transformer is required depending on where/when it was purchased.

1. Is the Helix Floor truly universal / multi-voltage (100V–240V, 50/60Hz) on every single unit?

2. Does this apply to all production batches/weeks, including early production runs, or were there any regional/batch-specific 110V-only versions ever made?

3. Can I safely plug it directly into a 220V wall outlet using a standard IEC power cable without a voltage converter?

I would really appreciate any clarification from the community or Line 6 staff.

Thanks in advance!
