I have a Helix Floor unit and in December I'll be using it for my first ever gig. I've been looking into Volume Leveling of patches and presets, but I can't seem to find any (pleasing) information about how to use the Volume knob on the Helix.
The information I found so far suggests I should turn the Volume knob al the way up as I plug the Helix in Front-of-House (PA) and adjust it to get the right volume. Now, I've been told that at the venue of the gig there will be a mic'ed up Marshall half stack where I can plug the Helix Output into the FX Loop's Return to make use of the power section of the Amp (Front-of-House would probably not work out for some reason). I also should bypass any Speaker emulation in the Helix because it will sound weird this way.
I tried a similar setup last night and found that my overall Volume went way up. I needed to set the Master Volume on the Amp to 1 and the Volume knob on the Helix to around 10 o'clock and that was already louder than before. Is this normal? Can anyone point me to good information about the use of the Volume knob on the Helix?
