Hi,

I have a DT25 head, which worked fine the other day, after upgrading to the 2.0 update. I turned it on today and it doesn't work. The power light comes on, the panel is lit, however no switches change their settings e.g. topology, channel A/B, class A/AB.

I have tried restarting the amp and pinching the class A and topology settings. This resets the amp, I believe, I hear some physical clicking inside the amp, but the swithcing does not work on the front.

This problem occurs whether plugged directly into the amp or via L6 link fomr my HD500.

Any thoughts? I have a gig soon!

Thanks,

Ben
