Bascially, for the cash nothing can touch this desk...
I did have a Mackie 1604 (not VLZ) until 6 months ago, and although I liked it a lot I found that to get the results I wanted would take a ton of outboard compression and more EQ than I had access to (ie unsweepable 3 band on the 1604).
The result was I sold the mackie and traded up to an 01v. Compression & 4 band EQ on every channel (unexpanded) it is sooo flexible I absolutely love it, the noise floor is really low too even with heavy compression on quite a few channels.
I have now expanded it to 24 channels via the 8 analog in board and my setup pretty much close to how I want it; I just use it for MIDI seq, no mic recording at all so I can't comment on the preamps.
I found it really easy to use too; the only thing Yamaha gets points off for are:
-Manual could be better: setting up digi input gain levels, etc is different from an analogue desk with regard to headroom etc, and they don't cover it in much detail like Mackie do with their products.
-Expand to 24 channels and the 'new channels' only have 2 band EQ and no dynamics processor access, although you can route (swap) them digitally to channels that do have such facilities.
-Can't overdrive the inputs, he he he, not a fault of Yamaha but the nature of the beast so can't complain, but a little subtle analog warmth (distortion ?) on the input channels is all I miss from My Mackie.
That's all folks !
