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.
