Congratulations
on
purchasing
the
Gemini
UMX-3
VCA
mixer.
This
state
of
the
art
mixer
is
backed
by
a
three
year
warranty,
excluding
crossfader
and
channel
slides.
Prior
to
use,
we
suggest
that
you
carefully
read
all
the
instructions.
With
VCA
technology,
audio
is
processed
in
a
voltage-controlled
amplifier
(VCA)
removing
it
from
the
crossfader
and
channel
slides
giving
them
extended
life
and
reducing
travel
noise.
The
crossfader
and
channel
slides
regulate
the
DC
voltage
that
controls
the
VCA
circuit.
Additional
advantages
of
VCA
technology
include
the
ability
to
provide
precise
curve
adjustments
for
the
crossfader
and
channel
slides
without
sacrificing
audio
quality.
For
additional
information,
refer
to
the
diagrams
on
Page

for
crossfader
adjustment
and
channel
slide
curve.
