<DIV><FONT face=Arial size=2>Laurie,</FONT></DIV>
<DIV><FONT face=Arial size=2>You have a point, but w</FONT><FONT face=Arial
size=2>e choose our DIY battles. For instance, you don't see much discussion
about, say, building MIDI fader boxes from scratch, because they are so cheap to
buy. Besides, this is Synth DIY, not Mixer DIY, but I hope this is close enough
to "on topic" for everyone's tolerance.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>And I'm sure that you can build a quality unit. One
question I have is why you want VC instead of MIDI control, but hey -- it's your
system.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>As far as I know, VC means using a VCA or Vactrol
or OTA for each function for which you need VC. With 4 bands of EQ plus volume
per channel, that sounds like a lot of circuitry. But, since each band of EQ
requires an op amp (right?) I guess that substituting a VCA isn't a big deal. By
the way, all those high quality VCAs won't be real cheap...</FONT></DIV>

<DIV><FONT face=Arial size=2>Phantom powered submixers?</FONT></DIV>
<DIV><FONT face=Arial
size=2>---------------------------------------------</FONT></DIV>
<DIV><FONT face=Arial size=2>Regarding cabling, how about using balanced lines
to link your submixers to the main mixer (a good idea for noise, anyway), and
running phantom power over those lines to power the submixers. Given the right
power supply (and cablings of sufficient gauge to carry enough current), I think
this would work.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>So, ATTENTION DIY PEOPLE! Let's stop talking Elby
out of doing it herself, and weigh in with your suggestions. :-)</FONT></DIV>

<DIV><FONT face=Arial>Seems to be a general thrust towards buying a
ready-built unit which is a bit odd for a DIY site!!!!.</FONT></DIV>
<DIV><FONT face=Arial>Anyway I am not convinced that I can't build a decent
unit (which would at least be 100% what I want and not a compromise or
contain additional unwanted/unused features) so will continue searching for a
VCE (Voltage Controlled Equaliser) and working on my VCA and VCPA (Voltage
Controlled Pre Amplifier)</FONT></DIV>
