4 inputs - 8 outputs connected via ADAT Lightpipe.  Just have to figure out how to de-couple this thing.

ok i think i see 4 dac chips there
U4 U5 U6 U7

and each has 2 caps
C38 C38 C42 C44 C48 C50 C54 C56

i would think that thats where you decouple... 

but im no expert

Yep, I'd say that's a good guess.  As long as U14 and U15 are just dc coupled buffers and the yellow/orange 16 pad devices are resistor arrays, that's the only location I see DC blocking.

If you use a continuity checker between the output jack positive signal, back to the non-DAC side of that cap you should measure zero ohms.

Beeeeeeeeeeeeeeeeeeeeeeep! 

The other side of the cap will, of course, have no DC path at all.

Hey Guys,

Thanks for the insight on this.  I have to get a new multi-meter,
mine died last week.

Wait a minute.....

Operating without a working multimeter.....

That's a violation of International Nerd Law! 

Dude!

You better get that rectified soon!
