I've experienced similar (well, vaguely similar) distortion on a
"horstbox pro" when echo cancellation is switched on for the zap
channels (ISDN).

Turning it off resulted in no distortion at all, but then i experienced
very strong echo at times. Switching on echotraining lowered the
distortion so that's currently the trade-off i have to live with.

HTH a little.
