EAW UMX.96 Owner's Manual
Chapter 10: VCA Control Section
The VCA (Virtual Control
Attenuator) section of-
fers a centrally located,
smaller VCA mixing
surface. The purpose and
function of this area is
identical to that found on
an analog console. Since
there are no Voltage
Controlled Amplifiers in
the UMX.96, the function
is implemented digitally
and given a similar but
different name.
The VCAs allow control of
assigned channels by a
single VCA master fader.
As on an analog desk,
the assigned faders do
not move, but the gain
setting of the VCA master
fader is added to the
setting of each channel
fader assigned to the VCA
group. Channels can be
assigned to multiple VCA
masters in which case
the result is cumulative.
Similarly, VCAs can be as-
signed to VCAs of a larger
number, also resulting in
cumulative results.
There are 16 VCA groups
organized in 2 banks of 8
faders each. Two VCA Select buttons (shown on the right side of the Figure above), VCA 1-8 and VCA 9-16,
select a bank of 8 VCAs to control.

VCA Channel Description
4-digit LED Display — This display shows the short names for the corresponding channel. This is usually
a VCA group but may also be an Aux/Group Master when Aux Mode is enabled (see Section 8.2.3.4) or any
other channel when Channel Follow mode is enabled (see Section 10.1.3 below). It also shows the frequen-
cies of the 31-band EQ when in control mode for the output RTA-31 (see Section 12.2.23). When adjusting a
fader, the corresponding display will temporarily show the fader value in dB.
Assign Button — This tricolor button mirrors the channel ASSIGN button on the upper and lower channel
banks. It is used mainly to assign VCAs to other VCAs and Mute Groups, as described in Sections 8.2.1.3 and
8.2.1.4. They also can be used for other channel assignments when another channel is under control using
Aux Mode or Custom Channel assign as described below. Note that VCAs can only be assigned to VCAs of
higher number (VCA 3 can be assigned to 4 but not to 2). This prevents VCA control feedback loops.
