If you want to use it for a crossover, then you will need a seperate DAC for each stereo output. A two way speaker would require two DACs one for the low frequency drivers and one for the high frequency drivers.
Am reviving an old thread, as interested to build a 3 Channel digital XO with the nano digi handling data from my computer based system

- Is there a problem that 2 or 3 DAC run in parallel ( jitter, phase, ??)
- I use the ebay DAC AD1865 NOS SRPP, i guess there is no way to have this DAC with 4 or 6 channels, I Shall have to buy another one or a pair
- May the dac be different for different channels ?

An all digital processor for configurations of up to 2 x IN, 8 x OUT using SPDIF and the same processing power as the 2x8 analog board.

Please see the product page for more info!

Is there a way to feed the board I2S, or at least get I2S out of it? Are there points I could tap on the board to get this out?

Well I found that you guys said no on many instances because it's too hard to tap the fine pitch leads. I just don't know any other way to feed a Buffalo III 8 channel dac, and I need all 8 channels and buying 4 different DAC's isn't an option.

I don't have the nanoDIGI so thats only a guess but maybe there are other points than directly on the DSP where you can tap the I2S signals. You have to know what you do though
It's much easier on the 2x8 since there are clearly marked test points.

Jean Louis,

- not a problem running the dacs in parallel. they will be sharing the same clock from the same SPDIF IC. Same clock domain.
- Each DAC will need to be stereo SPDIF IN - >STEREO DAC)

If you want to do I2S OUT, it's much easier to use the miniSHARC in this case. It was designed to be I2S IN/OUT. So no need to worry about the interfacing with the Buffalo. An adaptor card for miniSHARC to Buffalo III is actually in the works. We'll announce that soon :-)

Awesome news and yes I was just starting to look at the miniSHARC and I think that's the route I'll go. Brian told me that you guys would be working on a adapter card for the Buffalo III as well. Does the miniSHARC use all the same plugins and what not as the MiniDSP?

Plugins are not the same (you'll need a special plugin for the miniSHARC) but similar in look and feel
Of cause you will have more biquads and much more delay plus FIR!
