Helix LT
A full-size Helix floorboard with the same processing as the Floor and a reduced set of jacks. Same two paths, same 32 block locations, same eight snapshots, same models — it is the I/O and a handful of panel controls that are smaller, not the sound engine.
If your unit has a mic input, four sends and returns and a separate PHONES knob, you have a Helix Floor. If it is a 3U rack, read the Helix Rack guide. The sound engine is the same across all three.
The pages that exist nowhere else
Controls and footswitches
Every control on an interactive top panel, including the toe switch and the two EXP LEDs nobody notices.
Inputs and outputs
Every jack on an interactive rear panel — and a straight account of what the LT gives up against the Floor.
Specifications
The numbers that answer a question, with the Floor comparison on the lines where it differs.
What every model really is
All 440 amps, cabs and effects decoded from Line 6's own list.
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
Why it stops you adding a block when the meter looks half empty.
Rig setup
Pick what you're plugging into and get the cabling and the cab block state.
Snapshots and modes
Which layer a change belongs on, and why the wrong one leaves a gap.
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 the entries that are 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.
