Optical ADAT. The HDSP 9636 would be the master. There would be two
optical ADAT cables going out, one to each DAC1. You would sync the
DAC1's to the ADAT signals. If you used the HDSP 9652 then you could
use the word clock outputs to sync. Aaron Trumm (www.nquit.com -
another LAU user) is selling an HDSP 9652 used if you want to look at
that.
hdspmixer would create the specific mix you are looking for - quite
easy to do really.
I have no idea whether you can actually doing 192KHz in Linux. 96K is
not a problem.
As others have said I would stay away from the
FreeBob solutions at
this time, unless you have a stomach for working through whatever
issues you are going to come across. You could do a *Very* nice
high-end home theater system using an HDSP 9636 and a good set of
D/A's. You might look at one of the low-cost (<$250) 8 channel ones
for all the extra channels and use something like a Benchmark DAC1
which has really great sound, albeit a bit pricey but not totally over
the top, for left and right.
I'm a little confused as to what connection i would use with the hdsp 3696 and
the Benchmark DAC1 to get 24/192 in at least 4 channels.
Yes, thank you. I'm looking for 4 channels actually as i don't like center
channels (left, right, rear right, rear left). 8 channels is fine actually
as i can use the other channels for something. I may use it as as DAW
sometimes or multi-zoning,
Hsdpmixer sounds just like what i have been looking for, but i looked around
for details on it and could find nothing. Is this an app to interface with
the internal mixer of the card or is it the name for the mixer on the card
itself?
The HDSP 9652 has hardware mixing. hdspmixer is the app that allows
you to control it. It's part of the alsa-tools package.
I've read in the audiophile press that usb/firewire is more desirable then
spdif because usb/firewire has lower levels of jitter. Of course if the
difference is truly inaudible i don't care.
If you truly care about this then get an external word clock generator
from someone like Apogee. However I think starting with an HDSP 9652
and using it's word clock output would be more than acceptable for
studio level quality.
The less components and cables between the computer and the amps the better
(generally unless you need extra gain provided by a pre-amp). If i were to
use an RME Hammerfall DSP 9632 and go straight into an amplifier (monoblocks)
You cannot. The HDSP 9636/9652 has no analog conversion. You must go
HDSP->DAC->Amp.
I drive my studio monitor power amp directly from my 8 channel D/A. No
need for a preamp.

So if need to send it out to a breakout box. Would this be better done through
adat or spdif? I'm looking for at least 4 channels of 24/192 being delivered
to 4 monoblocks and i thought that neither could do that. If i got 2
Benchmark DAC1s they would not necessarily be in synch right?
Wrong. They must be in sync but they will be since your HDSP would be
the master and the DAC1's would be the slaves.
I've always liked the RME cards and i just read somewhere that Paul is
actually a RME dealer. I'd be looking to buy a card sometime this summer.
I'll contact you then.
Paul is a nice guy who can always use a sale I suppose.
Cheers,
