Helix Stadium XL Floor
The Helix Stadium with a built-in expression pedal, two instrument inputs, four effects loops and four control jacks. Same touchscreen, same twelve footswitches, same Clones and Showcase — a bigger set of connections around an identical engine.
If yours has one instrument input, two FX loops and no built-in pedal, you have a Helix Stadium Floor. Everything about how the two make sound is the same; read either guide for that half.
The pages that exist nowhere else
Clones
PROXY cloning — what it captures, how many you get, 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 means.
Blocks, paths and DSP
Four rows, and the caps that stop you before the meter does.
Songs and Showcase
Backing tracks, markers, flags and the transport.
Controls and footswitches
Every control on an interactive top panel — the touchscreen, the transport, the built-in pedal and the volume knob that only moves one output.
Inputs and outputs
Every jack on an interactive rear panel — two instrument inputs, four loops, four control jacks, and the two USB ports that are not interchangeable.
Specifications
The numbers that answer a question, with the Stadium Floor comparison on every line that differs.
Clones
PROXY cloning — what it captures, how many you get, 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 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.
Songs and Showcase
Backing tracks, markers, flags and the transport.
Rig setup
Including two instruments at once, and in-ears with the house mix.
Snapshots and modes
Eight snapshots, more footswitch modes than the MODE button suggests, and Combo mode.
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.
Troubleshooting
Symptom, cause, fix — including what is documented behaviour rather than a fault.
Firmware and backups
What an update changes, what it leaves alone, and the one-minute backup that means it never costs you anything.
