^^^ yes. itís likely either the AD cards or the cables feeding them (eg non balanced cables shorting pairs to ground etc.). Or maybe that group of preamp/preamp rack if coming from a single box/500 Rack etc. Swap the input cables (and so preamps attached to that) first. Crank up signal gen plugin to drive preamp or line inputs can make things lots easier to troubleshoot. Get out a multimeter and confirm the DB-25 cables are wired correctly/not wrong AES/EBU cables etc.
