Hi!
In my current recording setup i have an old ADI-8 Pro converter connected to my FF800. Recently i've encountered the following strange behavior:
When powering on the ADI-8 Pro unit, i get a random LED pattern on the frontplate, which changes with every power-on. One possible example can be seen here: https://www.dropbox.com/s/eu5iax4zuw0yv … 8.mp4?dl=0.
After some seconds, all LEDs get dark, but the ADAT output is still flickering, as is the ADAT 1 status LED of the FF800. Of course, the ADI is NOT connecting to the FF800.

But: After appr. 45 minutes (Sic!), suddenly all LEDs light up on the ADI, it connects to the FF800 and can be used from there on without any problems.

I'm wondering now what i should do with the unit? Any idea what the problem could be?  Can it get serviced/repaired, and if so, any rough ideas about the possible costs?

thx in advance!!
