I haven't gotten the update, but since the 1.4 thread is now closed I'll post some more observations here.
I have a Mackie sub that a friend of mine brought round for repair as it was overheating. Long story short, a set of replacement transistors solved the problem and of course it needed testing. So I dragged out the mixer and a W-Audio SM12 powered speaker to use with it. After annoying the neighbours with a 30Hz test tone I got on to trying it with some music and since it was all working find I thought I would finally try out the vintage EQ and Dynamics.
What I found was that the vintage EQ was considerably more prominent in its use, i.e. you didn't seem to have to add or subtract as much gain to have an effect and swapping back and forth between the vintage and modern alters the sound quite a bit. As an example, boosting 3.2kHz in the mid band on the vintage (with a narrow band setting) and then swapping back to an approximated modern EQ was reasonably dramatic. It went from bright to an almost flat sound. Its like the modern setting is almost attenuated in its settings. I do like how on the mixer page it shows the little knobs in place of the EQ graph... simple things, eh? :-)
Now this was just using some pc based music, I haven't had a chance to use it at a gig yet (think I would prefer time at a rehearsal to mess around to be honest).
As for the dynamics, well its quite fun playing with them to see what the settings do and they seem to work ok, its definitely an more simple way to set them up and being able to watch the way the "meter" moves gives some clues as to what each of the settings does. However, the big issue with it is that the meter scale only goes to +3dB and a lot of my programme was going off the scale, not really much use.
Hopefully this is helpful to someone.
