I got some output signal problems.
If send/return is not used (empty jacks) the output signal's suddenly very, very quiet - almost muted.
But if I use the effects loop, or just plug in a cable from send directly to return, everything's fine and sound's in regular volume.
This behavior's not normal, or am I off the wall
?!? Don't know, if there's something broken, or any jumper in wrong position?
Does anybody has issues like that? Thanks for help!
