I have a 324 card with my 2408 and I want add a 24 i/o.

Can I use the 324 card with the 24 i/o interface?

Thanks for your time.

According to this, you can't!!

Seems a bit rough.
MOTU "brags" about the interchangeability of interfaces and their compatibility with 324/424 systems on that very page.
Why the 24I/O, then?
Dang, I'm buying one soon and didn't realise this.

Thanks, elmarq, and tough-luck, microstudio!

PS: Microstudio, if you can do without the 24 extra outputs, perhaps the 24i will do the trick?

If I am not mistaken all the "newer" interfaces that support 192k all require the 424 card. Not sure why, but it appears the 324 card doesn't work with 192k?

Could be the newer AudioWire protocol.

I s'pose they increased the max. bandwidth for the cables.
Impressive that they also added an extra AW input on the 424 card.
Usually increased sample rates mean diminishing channel-counts.

Not in MOTU AudioWire land, it seems.
