Your main instrument input.
- Worth knowing
- It has a switchable pad and a selectable input impedance. If a guitar sounds harsh or dull, change the impedance. It sets how your pickups load.
Facts about the audio path
For a mono rig, use the LEFT/MONO jack
Both output pairs are stereo. The left jack of each pair carries a summed mono signal. The right one on its own carries only half.
Helix Cheat Sheet (Rev D)The ground lift is a physical switch, not a menu item
It sits between the sends/returns and the XLR outputs on the rear panel. Try it first when there is hum.
Helix Cheat Sheet (Rev D)The guitar input has selectable impedance
Set to Auto, it follows the first block in your chain, which usually works. Set it by hand if a guitar sounds harsh. A lower value loads the pickups and softens the top end, as a real vintage pedal does.
Helix 3.80 Owner's ManualUSB is 8-in / 8-out at 24-bit / 96 kHz
Enough to record the processed sound and a clean dry track at the same time, so you can re-amp later.
Helix Cheat Sheet (Rev D)The VOLUME knob does affect USB 1/2
The master volume is in the path of the first USB output pair, so your DAW level moves when you touch the knob. Record on a different pair to keep it fixed.
