Hi,

Ik have strange sync issues with my ADI 648 on 'cold' power up.

When I leave studio I always switch a main power switch do depower all devices. When I start working, I power on the studio with the main powerswitch. All devices (Computer with hdsp madi pci / Dynaudio Air 6 system /  / 2 x ADI 8 pro / ADI 648 and others) are connected to a central grimm wordclock and communicate with each other via Friendchip DMX 32 digital patchbay.

Problem is that sometimes on a fresh power up (via the main powerswitch), the sync led of the 648 stays flickering when everything else is in sync already. When I depower the the 648 with its powerswitch or disconnect the 648 from the powersource and power it on again, the led stays flickering. I have to shut down/depower the computer with the hdsp madi first and start it up again to let the 648 stop flickering.

I already tried to sync the 648 via madi optical / or madi coaxial, or do the same thing with the computer, but nothing helps. In all situations I have to depower the computer before the 648 will sync. Strange thing is that it doesn't happen all the time... The studio is on a separate (clean) power group.

Anyone?
