Sorry Nigel - i don't want to take over the thread, and this will be my last post on the subject.

Rusty999. i know the person in the UK - he lives in Scotland and brought the Audya module from Thomann so we could not assist. I felt sorry for him, but nothing I could do.

FYI. I have the very first Audya 4 module to come out of the factory here in the showroom (we use it as our demo unit and it has not been modified.), in fact we in the UK had the first shipment worldwide so all of our initial order were from that very first run. I'm sorry you had a problem, but its a huge leap to state the entire first Audya 4 production run had the same issue - it did not.

I do realise you have did have a genuine and isolated problem and rightly feel annoyed. But I must point out, had all of those initial Audya modules been at fault Ketron would have been legally required to make a complete product recall - plus they would not have passed the very strict and extensive European certification tests in the first case.
