Hi,

Is it normal (if I have my ADA8000 pluged in adat in scope with scope master at 48kHz) to have big noises on the channels where there are nothing pluged ?
if I unplug from STM1632 the adat sources where there is no entry the channel where my SM58 is pluged works well.

what sort of big noises ? Hiss, crackle, or pop ?

crackles

I've had that problem before where crackles occur at one sample rate but not another.

Is this on PCI cards or XITE ?

And does it happen on odd, even or all unplugged channels ?

Anyway, this can happen if :

1) You don't have the ADAT connection both ways ( eg 2 ADAT cables )
2) The two devices are not on the same sample rate
3) Master / Slave not set correctly on all devices
4) The ADAT ports need cleaning (compressed air)
5) The ADAT connectors are loose (try other cables)

ok thank I'll check

(PCI cards)

I think 4) The ADAT ports need cleaning (compressed air)
because the connectors are new.
