Is that stereo or 8 channel ?
BTW the on-board hardware can be clocked down to 96K or 48K but the default is 192K.
cheers
For the SHARC part used in the UP the max number of taps is 800E6/48000 = 16666 or about 8000 taps per channel at 48K for 2ch operation.
cheers
This box looks very interesting indeed. One question about the DSP functionality: Is it possible to load filters generated from room correction software such as Acourate, Audiolense or Dirac?
You can load FIR filter tap coefficients from a file so I don't see why not.
Depends how many taps you need of course because that resource is not unlimited.
cheers
$2.5k is high diy territory
For that kind of money i could buy a Lynx Hilo, how does it compare?

I don't think that they are comparable.
A Hilo is a converter interface (A/D and D/A). It looks as thought it would still require some DSP engine to implement a crossover network plus some expansion cards to get eight channels of analog output. The bare bones unit is about USD 2700.00.
The device here has a phono stage plus two other analog inputs (balanced and unbalanced) plus digital inputs for about 2-2.5k USD. It has sufficient DSP horsepower to form a complex crossover network for a pair of 4-way speakers.
I am very seriously considering one. It seems like a cool piece of kit and would solve numerous problems for me.
That's a strange comparison. Lynx Hilo is 2 channel AD/DA converter. Analogue-Precison has 8 channels and functions as a crossover filter including advanced FIR filters.
The Lynx Aurora 8 doesn't have the same functionality either. The only one in the pro industry that comes close is Metric Halo, but it doesn't have FIR filter, nor a display or remote capabilities. Sure, these pro units have other functionalities of course as they are meant for studios.

DEQX HDP-4 or HDP-5 is a product that you could compare it with to some degree. But I'm quite certain the Analogue-Precison holds higher quality in terms of lower distortion, besides offering two extra channels, a proper display and greater software flexibility.

I would say the price of the Analogue-Precision is very competitive.
If you mean stereo 5 to 8 way then it is possible to link two boards to get a total of 16 channels but the base unit we currently offer only has 8 channels. But we are working on providing an extra two channels via one of the S/PDIF outputs using an external DAC. Typically this would be used to power a pair of subwoofers to make up a stereo 5 way system.

Ok, I'm sold
But why is it so important the crossover is handled in the DAC. I plan to use acurate's fliters/ software before it reaches the DAC.
Is'nt this feature something I eventually won't use or need? Please inform me? thanks

The crossover is implemented in the DSP not the DAC. Even if you feed two channel audio from a PC that does some DSP functionality you still need an external crossover if you are going to implement multi-way active speakers.

and finally I put DSP in use
I'm still trying to figure out audio weaver
for start I used tree way template from analog precision web page and change slope from 4 order to 2 order LR.
What I would like to know, if I chose 2 order LR, do I need to reverse polarity on one driver manually or is it made automatically via software ?
If I have to make it manuall is it done like on the picture ?
thanks

Hi, I'm using;
scan speak 2904/7000 - Aleph mini
scan speak 18W8545 (closed) - AlephX (around 60W - 8 mosfet per amp)
scan speak 2 X 21W8555 (closed around 46L - stuffed with sonofil) - right now amplifier is LJM L30D (D class) until I finish CFA amplifier from dadod
