[sdiy] AGND and DGND etc. When to bring together?

[Julian]

Im just working out how to power a system here, and thinking again about the power distribution board.

Most of the 5u modulars have two ground lines, whereas companies like doepfer bond together to one at the modules themselves.

I dont know a lot about this, and im wondering what i should be up to with it all.

I have one powersupply (a power-one one) thats powering both by doepfer system at 12v and some diy modules (ele4music etc which have
the grounds split).  These will be running off a different bus, but the same psu.


Im wondering the best way to do all this?  And i see designs for busses with caps etc. on them too, whereas the doepfer bus is no
more than strips. (?)

Basically i need a grounding and power distribution 101... Any volunteers? ; )

Thanks again,

Julain
