Yes, wouldn't that be nice. I saw those from the start. But I think it's a little too deep -- and definitely much more expensive than the 2400.
I know the Soundcraft Live 8 has a full meter bridge, but that's a fairly big board ... the 24 channel version looked to be about 30" deep and 48" wide -- definitely too big for our space.
Also, fyi I use the groups and auxes to route to the individual speakers ... I need to be able to run a multi-channel system, not stereo or LRC. When routing sound effects for our dramas I need discrete channel routing to each of the 6 or 8 (with FX speakers) output channels. Now if there was a board with 6 or 8 matrix outs on it, then I could actually use the groups as groups. Other than the very large analog boards, I think the LS9 digital is the only other option here .... or start going to VCAs. But again, those boards are physicall too big (and too expensive for this upgrade).
