@djx I noticed exactly the same : if you have one cable that goes directly from A4 to the mixer, and the other goes to inactive AH that goes to mixer, I hear a huge volume drop. Like AH would not be true bypass, when I would expect the contrary.
I (think I) understand what has been said above about gain staging, but IMO an inactive AH should not make the sound drop so much.
What do you think of this ?
Do you observe the same thing or is it an improper cabling of mine ?
Is this also true with mk2 ?
