well, guys … I bring you my experience.
I also sent my new P4 back for the problem with the left jog that the display was not working. I think I was the first to accuse this problem and promptly solved it by Denon.
I also got the box with the seals cut and then replaced. The console could be seen by eye that it had been opened in some way, it had signs on the display protection film, but nothing special.
I immediately contacted the Denon representative who was following me, and he said, apologizing that they had not warned me in time, that the console had been tested by the Denon technician before shipment, just to avoid having the problem of yet another defective unit .
This is what I have been told. If true, I appreciate it from Denon, of course the units must not arrive damaged in any way.
ahh mine also came from the German distributor.
