Helix Stadium Floor
Line 6's flagship floor modeller and the first of a new generation: a touchscreen, eight parameter knobs, twelve footswitches, and a built-in playback and automation engine called Showcase. It runs the whole HX model library plus a new set of Agoura amp models, and since firmware 1.3 it can clone your own amps.
If your unit has a joystick and a monochrome screen, you have an original Helix — read the Helix Floor guide instead. The Stadium XL is the same brain with more footswitches and a second expression pedal.
The pages that exist nowhere else
Clones
PROXY cloning, added in firmware 1.3 — what it captures, how many you can use, and the mono rule that catches everybody.
What every model really is
All 440 amps, cabs and effects decoded from Line 6's own list, plus what Agoura actually means.
Blocks, paths and DSP
Four rows, and the caps that stop you before the meter does — including the ones unique to clones and Agoura amps.
Songs and Showcase
Backing tracks, markers, flags and the transport — the automation engine no other modeller has.
Controls and footswitches
Every control on an interactive top panel — the touchscreen gestures, the transport, and the volume knob that only moves one output.
Inputs and outputs
Every jack on an interactive rear panel, including Nexus, the microSD card that holds your songs, and the two USB ports that are not interchangeable.
Specifications
The numbers that answer a question, with a note wherever the bare figure misleads.

All 440 amps, cabs and effects decoded from Line 6's own list, plus what Agoura actually means.
Levels
Two settings decide whether it sounds like the demo or sounds broken. Both live in a menu, and neither is a tone control.
Cabs and IRs
What an impulse response is, how to load one, and why a downloaded preset can load fine and still play the wrong cabinet.
Blocks, paths and DSP
Four rows, and the caps that stop you before the meter does — including the ones unique to clones and Agoura amps.
Songs and Showcase
Backing tracks, markers, flags and the transport — the automation engine no other modeller has.
Rig setup
Pick what you're plugging into — including in-ears with the house mix, and playing to tracks.
Snapshots and modes
Eight snapshots, more footswitch modes than the MODE button suggests, and which layer a change belongs on.
MIDI
What a controller can actually reach, the three messages that recall a sound, and the trick that lets one preset serve several songs.
Questions and answers
Straight answers to the things people actually ask, in a sentence or two each.
Troubleshooting
Symptom, cause, fix — including the entries that turn out to be documented behaviour rather than faults.
Firmware and backups
What an update changes, what it leaves alone, and the one-minute backup that means it never costs you anything.

Clone, flag, marker, Showcase, Nexus, Agoura, Matrix mixer — plain definitions, with why each matters here.
