Helix Floor
A full-size floor modeller with two DSP chips, two signal paths, and an unusually complete set of jacks — mic input, four sends and returns, XLR and quarter-inch outputs, AES/EBU and S/PDIF, and a Variax port. It is the flagship of the original Helix generation and everything else in that generation is a subset of it.
If your unit has a touchscreen, a Song button and a big volume knob on the left, you have a Helix Stadium — a different generation with a different manual. If it is a 3U rack with a guitar input on the front, read the Helix Rack guide instead.
The pages that exist nowhere else
What every model really is
All 440 amps, cabs and effects decoded from Line 6's own list. “Brit 2203” is a JCM-800; “Cali Rectifire” is a Dual Rectifier.
Blocks, paths and DSP
Why it stops you adding a block when the meter looks half empty — the hard caps, and the six changes that actually buy back space.
Troubleshooting
Symptom, cause, fix — including the several entries that turn out to be documented behaviour rather than faults.
Controls and footswitches
Every control on an interactive top panel — twelve capacitive footswitches, the joystick, and the toe switch nobody knows is there.
Inputs and outputs
Every jack on an interactive rear panel, including the mono rule that makes rigs sound thin and the ground lift that fixes hum.
Specifications
The numbers that answer a question, with a source on each line and a note wherever the bare figure misleads.

Rig setup
Pick what you're plugging into and get the cabling, the cab block state, and the thing that goes wrong.
Snapshots and modes
Preset, snapshot or stomp — which layer a change belongs on, and why the wrong one leaves a gap in your sound.

Straight answers to the things people actually ask, in a sentence or two each, with a link to the detail.
