8.2.4 How to Use the VCA Masters Plus
the Group Master Faders to Obtain
the Functional Equivalent of 16
Subgroups.
Let's assume the object is to obtain a stereo output
(or a pair of mono outputs). Some input channels can be
assigned to the Group busses via their assign switches
[1]. The eight Group Master Faders [42] then control
these eight subgroups, and the Group-to-Stereo
switches [40] combine these eight subgroups for control
by the Stereo Master Faders [58]. At the same time,
other input channels are not assigned to the groups.
Instead, they are assigned directly to the stereo bus
(and the Stereo Master Faders) by means of their ST
assign switches [3]. In order to exercise group control of
the direct-to-stereo input channels, those channels' VCA
assign switches [22] are engaged (typically just one
switch per module). The correspondingly numbered
VCA Master Faders [47] then exercise control over
subgroups of input channels which are assigned directly
to the Stereo Master Fader. The eight VCA Master
Faders plus the eight Group Master Faders thus control
16 different subgroups, all of which are mixed into the
same stereo (or dual mono) output.
NOTE: In this application, any groups requiring overall
signal processing (such as compression of a drum group,
or flanging of a vocal group) should be assigned to the
Group Master Faders. This allows the Group INSERT
IN/OUT patch point to be used to handle the overall
mixed signal; there is no corresponding means to process
a group which is created via VCA assignment.
