Jorn,
What great help, thanks very much!! As for the center channel, maybe I will ultimately follow your advice; I have all the parts for two LXmini's; I bet one of those would be a nice center speaker. But I'm taking a little rest from all the amplifiers and configuring... :) That Behringer 8200 sounds good. But, should I get another Tango24 if it's not much more?For now, I love your idea about using the motherboard's spdif to get 2 more channels!! I already have everything I need to do that. And though I haven't done it before, I should be able to measure delays and sync up the different speakers by adding a little delay here and there in my LADSPA/ecasound chainsetup. I have to have the optical isolation; never was able to get rid of all the hum from my computer...
Do those expensive D/A boxes have a lot lower noise?
Thanks again!
John

Hi,
Just a little question - I have an RME9652 connected to a Tango24 to give me 8 d/a outputs via ADAT; but I really need 9 outputs. I only really need ONE input, for testing/crossover design. The 9 outputs I need are: front L/R low/mid/high, center, L/R surround.
Hmm. You mean you want active three-way on left and right, but run the center fullrange? Nothing against passive designs, but I don't think it's wise to have a vastly different design for the center (since the rest of your mail sounds like you're after high quality and detailed control). So maybe upgrade to 16 ADAT outs anyway, to ease the pain of missing just one extra out? ;)
I understand you are not going to connect the speakers via ADAT (and if you are, you might want to reconsider...), but there's gonna be a DA box in between, right?
You could abuse the analog outs, or use the SPDIF out pair for the surrounds... if you need sample accuracy in the lab, it might be wise to measure as the output latency between ADAT and SPDIF/Analog might differ, but in practical use it will be negligible.
So I'm wondering the nicest way to do get my 9 ADAT outputs. Maybe I should just look for a good deal on another Tango24... or, get a Behringer 8000 d/a for less money, and use it for the L/R surround channels.
If you go the Behringer way, get the new one (8200 I believe), they fixed the power supply, so the thing is less likely to die on you in a bad moment...
Both those options give me 8 more inputs that I don't really
need right now... Is there something reasonable I might buy (and sell my Tango24), that has ADAT, with from 10 to 16 outputs and 8 or less inputs?
With these simple options like the ADA 8200, you really can't save much by leaving out the inputs. If you want to go up a notch, there's the DirectOut Andiamo 2 DA (no inputs), but I guess that thing is around 2k euros, and it only takes MADI input. And then there's the Ferrofish boxes, quite full-featured with ADAT and MADI I/O in addition to all the analog lines.
