CROSSOVER
SETTINGS
AND
GAIN
ADJUSTMENT
Your
Polk
Audio
power
amplifier
needs
to
be
adjusted
carefully
to
achieve
maximum
performance.
These
are
some
guidelines
to
follow
when
fine-tuning
the
amplifier.
•
For
full-range
and
simultaneous
stereo/mono
bass
applications,
the
crossover
selection
switch
should
be
set
to
FULL
If
the
amplifier
is
driving
your
sub-
woofers,
set
the
switch
to
LOW,
and
for
mid-bassi
midrange
output,
set
to
HIGH.
•
The
crossover
frequency
control
needs
to
be
adjusted
to
suit
your
particular
system.
For
subwoofer
appli-
cations,
try
and
keep
the
setting
low
enough
to
prevent
image
smearing
(you
should
not
be
able
to
hear
male
voices
from
the
subwoofer)
but
not
so
low
as
to
create
a
gap
between
the
subwoofer
and
the
mid-bassi
midrange
speakers.
For
mid-bass/midrange
settings,
try
to
keep
the
setting
low
enough
to
keep
your
sound
stage
in
front
of
you,
without
overdriving
the
speaker.
It
will
be
to
your
advantage
to
spend
some
extra
time
with
this
adjustment,
listening
to
familiar
music
or
system
set-up
discs
to
achieve
the
kind
of
musical
reproduction
that
you
prefer.
•
The
gain
adjustment
allows
you
to
set
proper
signal
match
for
clean,
quiet
amplifier
operation.
For
full-range
and
simultaneous
stereo/mono
bass
applications,
start
by
playing
some
music
you
are
familiar
with.
With
the
gain
adjustment
on
the
amplifier
in
the
middle
of
its
rotation,
bring
up
the
volume
on
your
head
unit
to
the
3/4
volume
setting
or
until
you
start
to
hear
distortion
or
clipping.
If
you
hear
distortion
before
you
reach
the
3/4
volume
setting
of
your
head
unit,
reduce
the
gain
setting
on
the
amplifier
and
start
to
raise
the
head
unit
volume
again.
When
you
can
listen
to
the
music
at
or
slightly
above
3/4
on
your
head
unit
without
audible
distortion,
slowly
raise
the
gain
of
the
amplifier
until
distortion
is
heard,
then
back
off
the
gain
until
the
distortion
is
not
audible.
This
setting
will
allow
you
to
reach
full
output
with
all
but
the
quietest
of
source
material,
while
avoiding
excessive
noise
in
the
system.
NOTE:
Polk
amplifiers
use
a
digital
gain
control
with
a
finite
number
of
adjustment
steps.
A
very
small
adjust-
ment
may
not
cause
any
audible
change
in
level.
