TRS Outputs, Line Level or Instrument Level and is that adjustable?

I can’t find anywhere in the manual if the TRS OUTPUTS are line level or instrument level or if there is away to adjust this.

I’m

Wondering the same thing, using my new nano as the amp and my helix floor for all effects before and after so not sure if I should have the helix in/out to the Nano set on line or instrument

The L/R TRS output level is dictated by the “Level” knob.

Per the manual:

It looks like if you plugin TRS cables, it changes.

Good reply. I would add that +10db or +16db are pretty “hot” (loud). My powered monitors want +4db. I have a pair of Rothwell XLR -10db attenuators which I plug inline. While turning down the output volume has a similar effect, inserting the attenuators means I don’t have to worry about clipping.

Anyway to OP and the Helix - when turned down to say 60% the output of the Nano is line level.

That sounds similar to Strymons..
