So the plan is not to have assembled any of the pin headers on Expansion Ports 0 and 1.
(Just as a reminder, Expansion 0 is for I2S output and Expansion 1 is for I2S input).
This way you can easily adapt your own wires/connectors - indeed, un-soldering a 28 position pin header is not something I would recommend unless you have the proper equipment.

Also, phono (RCA) connectors can be left unassembled on request - there were a couple of such a request in this thread. By default, all RCA connectors are assembled.

How does that sound?

The expansion board will come at a later time.
The main board is ready to detect an expansion so that in can be installed in a plug&play fashion.

Another strange question, are the two expansion ports identical in function ?

Didn't se the earlier postpost so never mind.

Ok cool - hope its not too long a wait

Can the single be configured in mono mode so it could do up to 8 mono per unit?

Can you please elaborate?
Sorry, I'm not quite sure I understand what you mean.

I belive he's asking if there is a posibility to run it as a 8-channel mono version.
It's quite common among your usual "public adress" xo's.
I belive my old "Lem dx24" can do that.

Yep, that's it. As I need 5 way, running 2 units, each in mono mode gets me more than 5 outs per side, but only if there is a mono mode. Of course waiting for the expansion is more sensible and I'm guessing a fair bit cheaper?

Then there is the issue on not really being able to split the digital signal so one using is def best.

I am testing using 2 Behringer 2496's in mono mode like that at the moment, but input is only analogue.

The expansion boards - are they just copper or something more?
