Yes, this configuration will be working fine. in eight-channel mode you can use less than 8 channels.

OK finaly got most of the money for my project. Before I start I have one question. I have the u2i and an going to be using 5 dacs with it. 2 in mono the rest sterio. Now my question is. Will the u2i have enough power to pass data to all 5 DACs or will I need to boost the i2s signal some how? And yes its an 8 channel dac setup that I am looking at with the sterio pair in dual mono. Thanks Andy

This will be a very exciting project! My advice would be to start with one DAC, and to confirm that everything works. Then you can start implementing the big plan. You may have to use buffers on the clock signals. The GMR outputs can handle 3 DACs, more than that can be difficult.

Make sure that you are using the same DVCC power supply for the exaU2I and all DACs.

Regards,

George

Thanks for that! I will start a build diary when I have all the parts together.

Thanks

Yes, would like to register my interest for purchasing one. Even the current one has become my preferred transport for the AckoDAC System

Mine is all 9018/12 DACs so hopefully you would maintain support for these.
The rest on the list is really good, native DSD especially. Possibly dedicated 2CH or 8CH versions if these make things more optimized?

OSX support?

Is the I2C a slave or master? Can the sample rates be read over I2C? I will be using the AKC12 Controller (master), so DAC Vol Cntrl is taken care of but sample rates from EXA2UI needed (for display purpose mainly).

Those U.FL coax, if you could leave it unpopulated would make it easier for my DAC that uses the smaller w.fl types. I could kludge a connection in place.

From the looks of it you have got re-clocking done after the isolation. If true this is great! For your current version (2.0) I am doing the re-clocking externally using a separate module after the isolators. So this could become redundant

Has the dimensions and mounting positions been finalised? Nice if you could keep it the same as the current one for easy upgrades. ETA? would like to start the integration process already.

Well done and thank you for the great efforts!

Same here! Interested in the new version but the 2 channel version.

Do
