3.7.1.1
Menu – LCD Display
The LCD display contrast setting can be adjusted to suit varied lighting conditions and viewing
angles.
Use
the
left/right
buttons
to
the
right
of
the
Contrast
parameter
to
adjust
the
contrast
in
percentage
terms.
3.7.1.2
Menu – Audio Settings
The
audio
settings
offer
three
configuration
options.
Choose
Output,
Input
Gain,
or
Output
Gain
as
needed
using
the
left/right
arrow
buttons
in
the
second
row.
I. Output. The V-‐Machine’s audio output can be set to either mono or stereo. Some plugins
only operate in mono. If you’re using one of these, it may be desirable to output the
same
signal
from
both
physical
outputs.
It
may
also
be
necessary
to
send
an
identical
mono
signal
from
both
outputs
so
you
can
send
the
same
signal
to
an
amplifier
for
monitoring
and
to
the
front-‐of-‐house
mixer
in
performance
situations.
Use
the
left/right
buttons
in
the
third
row
to
toggle
the
setting
from
stereo
to
mono.
II. Input gain. The V-‐Machine’s audio input gain can be adjusted to accommodate differing
input signal levels. This is very handy when using the V-‐Machine as a real time audio
processor
(effect
unit).
Use
the
left/right
arrow
buttons
adjacent
to
the
Input
Gain
label
to
adjust
the
input
level
up
or
down
in
1dB
steps.
This
parameter
can
be
set
from
0dB
to
+35dB.
If
you’re
sending
a
low-‐level
signal
to
the
V-‐Machine,
you
may
need
to
raise
the
input
gain
parameter
to
insure
that
the
signal
is
loud
enough
when
it
reaches
your
effects
plugin(s).
Conversely,
if
the
signal
is
already
at
a
high
level,
you
may
need
to
reduce
the
input
gain
in
order
to
avoid
overdriving
the
effect
plugin(s),
which
would
result
in
distortion.
Quick
Tips:
With
some
effects
plugins,
setting
the
input
too
low
may
result
in
extra
noise
being
added
to
the
signal.
If
the
output
of
the
plugin
is
low
and
needs
to
be
boosted,
you
should
try
lowering
the
output
and
raising
the
input
gain
instead,
as
this
may
allow
the
plugin
to
work
more
efficiently.
On
the
other
hand,
if
you
hear
clipping
distortion,
check
the
input
gain
to
see
if
it
can
be
lowered,
as
this
may
eliminate
the
clipping.
Note
that
the
input
gain
parameter
is
not
an
analog
pad;
it
adjusts
the
level
of
the
input
signal
only
after
the
signal
has
been
converted
to
digital.
If
you
hear
clipping
distortion
that
isn’t
removed
by
lowering
the
input
gain
parameter,
try
lowering
the
level
of
the
analog
audio signal being sent to the V-‐Machine.
III. Output gain. The output gain can be set from -‐42dB to +14dB in 1dB steps. This
parameter
is,
in
effect,
the
V-‐Machine’s
volume
knob.
It
affects
both
the
line
outputs
and
the
signal
sent
to
the
built-‐in
headphone
amp.
(The
headphones
also
have
a
volume
knob.)
Quick Tip: To maintain optimum headphone output level, you may prefer to keep the
output gain parameter up at a high level and reduce the level of the V-‐Machine’s signal
