DSP Xover project (part 2)

How much is it ?

How do you program it ? PC or User Interface ?

do you have a website ?

I don't have pricing information yet, but it's going to be cheap.

Programming takes place via remote computer with a cross-platform control application. User interface is for source selection, preset, volume ... and some goodies

Yes I have a website but there's no information relative to this board at that time. I need some more time until I can release the product.

Below is a pic of the PCBs before assembly. At that time I was just making sure that the connectors were fitting properly.

Note that all OPs are on sockets so one can use his favorite model. Also, the caps on the signal path are Through-Hole so easy to replace.

Hey, looks good !

Definitively interested
Best regards from France

[mvaldes]

indeed a great job....
a couple of question

in case of a digital only use, is it possible not to populate analog circuit?
i2S is available as input too?

[ds23man]

Looks very nice. The analog volumecontrol, what kind of chip do you use? Cs3318?

[Trevor White]

i don't see any tracks on the top layer. is it a two layer board ?

[qusp]

possibilities for tapping balanced output filters?

if not I second this

in case of a digital only use, is it possible not to populate analog circuit?

looks like a 4 layer board trevor, application notes for DSP chips would be unlikely to cover 2 layer designs, I can see plenty of vias which hints at multilayer

i'm interested too, but mainly digital out as I have the dac side fully sorted with a 2 balanced sabre dacs

Thanks all for your comments!

I intend to make available a 'light' version beside of the full one.
The light version would have no analogue volume control, and volume would be handled digitally in that case. Note however that the user of such a board would be able anytime to add himself the chip and get analogue volume, but this will require fine pitch smd soldering.
This would allow users on a budget to make some savings because the bare analogue volume chip is rather expensive.

Regarding I2S, yes it's available as both input and output.

Well consider me thoroughly interested!
