Headphone output distorted
I got my Quad Cortex today - nice device. Connected to power - updated to 1.4.1 - guitar connected - headphones connected - preset selected - guitar started:
→ Sound from the headphones is distorted…
Sound recorded via USB in Logic Pro X and listened to with the same headphones via the QC → distorted.
Listened to the recorded sound with the same headphones directly from the headphone output of the mac → everything is fine.
Sound via output 3 on the QC to an external Fender Twin → everything is fine.
Headphone settings on the QC are unchanged from the factory settings (HP Level 0.0 dB / Multi Out 6.0 dB). Changing the settings does not bring any changes. QC resets → no change.
Do you have any ideas what it could be? Is the headphone jack on the QC broken?
