:D I have 3 MOTU 2408's connected to a DM4800. Tracks coming into the DM4800 via TDIF sound great, but when I send tracks via ADAT, I get nearly total distortion. When the track is played with the master send at 0 db, I can make the track out although it is pretty distorted. If I turn the track up a bit it goes to total, clip-busting static. The digital trim on the inputs are set at 0 db. I might be wrong, but I don't think clocking is the problem. Everything is clocked off word clock at 41.1.

More details: __________________________
All three MOTU 2408 units are setup as follows.

Bank A
TDIF IN/OUT <-> 4800 TDIF IN/OUT

Bank B
ADAT IN from external gear
ANALOG Out

Bank C
ADAT IN <- 4800 ADAT OUT
ADAT OUT -> 4800 ADAT IN

Re: ADAT INs = Distortion

Hi

I have a similiar setup. I have the same problem with a ADAT card.

My solution was to sync the MOTU via ADAT from DM 3200.

Best regards

That direction didn't work with me, but clocking the DM4800 from a 2408's ADAT did. Thanks for the help.
 
Hi

I use it only for additional I/O (+ 8 Analog I/O or you can switch between different I/O of ADAT or TDIF, that means you can connect 6 different gear and then you can switch them. This is comfortable when you don't have good acces to the connections)

Best regards
 
Not, as you have it set up, for 40 channels of recording and playback?
