As it say on the soekris website "We are currently looking for additional online webshops to resell our products, primarily in USA and Asia, but also for other major markets."

Have talked to a couple, but haven't found the right one yet....

Is the diyAudioStore an option?

Soekris, I have been following this thread on and off, so please pardon me if this question was answered already.
As I understand it the FIFO on the input makes it pretty hazardous to use several boards simultaneously in an active crossover setup.
I think it was discussed early in the thread, but is there a way to synchronize several boards fed from AES3 signals with a common clock?
(let's say a miniDSP UDIO-8 for example)

Don't know how you got that idea, it's not a problem, multiple dam1021 running on same clock will sync to within a few uS, multiple dam1121 can also be run synchronous.

How far away from each other may two 1121 be?

Probably not, they need to carry the whole DAC range, and be able to participate at events....

As far as you want, as long as the signals meet setup and hold times, which will limit how far they can be from each other....

So 6 meters should be OK?

What cables would you recommend?

DAM 1121: J3 14/16 (CLK) can they be connected by a twisted pair and boards configured as slave and master and J3 14/16 becomes input when slave and output when board is master?

Manual talks about Input Common mode Range and Output Swing...

Or must there be a third, external osc?

Seems like I forgot to add setup and hold time to the manual, we're talking about 5 nS, so 6 meters will be kinda hard, but not impossible if you buffer the clock and signals and follow all high speed design rules....

In practice, when using the clock from the oscillator on one board feeding the other board, maybe 10 cm, when using an external oscillator feeding multiple boards, maybe 60 cm....

Multiple dam1121 are really supposed to be mounted next to each other.
