Ways to use the new features.

Rdmitch:
Running the same song from an iPod thru 2 channels with reverb and delay turned on I tried to see if there was any noticible difference.  Routed to subgroup 1 and to vca1 I noticed no difference at all.
When the fader (either vca 1 or subgroup 1) were reduced the fx dropped equally.

While there may be other subtle differences, it appears for my purpose either would work fine.
Maybe it's because Mackie set up the option for post fade EQ .

sam.spoons:
if the fx send is post fade the DCA will affect both the dry and fx equally (assuming the fx master send or return is NOT in the DCA). If the fx is returned to the same group as the dry channel the group fader will also affect both equally as the group fader is downstream of both the channel fader and the fx return. Each, basically, is achieving the same effect but at different places in the signal path. There would be subtle differences with dynamics processors if used as send fx but as they are usually used insert/pre fade anyway it should not be an issue.

Sam your X32 training is starting to show, but you are exactly right calling Mackie's "VCA"  a DCA cause that's what it is. These are no more "voltage control amplifiers" than the man in the moon.  ;D Johnny come lately Mackie haven't earned the right to change 20 yrs. of audio technology to suit their marketing needs. If someone is interested here is a history of VCA's from some of the early developers.
  http://www.thatcorp.com/History_of_VCAs.shtml     Does any of this remotely resemble what Mackie implemented??
They could also adopt Midas's VCA definition " Variable Control Association". Since VCA is not in Mackie's glossary maybe they're not sure what they've done. One thing they haven't done is update the block diagram on the DL1608, DL806 to reflect MF 3.0 changes. My advise to anyone here commenting on what is and isn't, RTFM at least twice. Of course it would help  if the info was correct. Don't get me wrong this manual is leaps and bounds above the prior doc's such as the 1604 series. Interesting is the total lack of any mention of the well debated Channel Trim control and recall. I guess it's not important to them. I may have to agree with them on this but it should still be in the manual explaining it's intended use. I won't be getting to this for at least another 2 weeks because of tests that require MF 2.1.1. so all my info on MF 3.0 is from the manual and posts here.

robbocurry:
Digital trim addressed on page 30 of the reference guide. Didn't need to RTFM to find that out.
Does it REALLY matter if it's called a DCA or VCA in this device?
We get the idea what it's trying to achieve, no "X32 training" necessary.

Does Mackie use VCA terminology because of the manual gain pots on the DL?
Has Mackie stated what VCA stands for in this product? Genuine question, I'm too busy actually using the mixer to "RTFM" twice.
Very costless accessory?
Virtual control amp?
Variable cost analysis?
Very contracted anus?
Vicious critical attack?
Verbal contract applies?
Voltage controlled amp?

Please, enough of the nit-picking!

sam.spoons:
No I don't suppose it really does matter what it's called  ;)

I called it a DCA 'cos that's what it is (X32 training aside WK :laugh:)
