Hello Dieter,

Last year I bought an A155.
It worked very well.
A few days ago I also ordered an A154.
After making the connections fun was over sadly.
I did some investigation (I already have two sets of 155/154 which work fine) and comparison I discovered that the wiring on the A155 is wrong.
Flatcables red stripes are all opposite!
This looks like a misstake made with production.
I notified Thomann for returning the unit.
Hope this will be solved under guarantee.
Or do I have to send it to Doepfer

Best regards
Jacco Ville
