SETTING
UP
SYSTEMS AFTER INSTALLATION FOR BEST PERFORMANCE
General:
At
this
point
you
are ready
to
get
more specific
on
the
settings
for
your
amplifier.
Subsonic:
This setting acts
as
a
low
frequency
cut
off
for
your
system
bass
reproduction. The
point
that
you
set
it
at
cuts
off
any
frequencies from reproduction
beyond this point. The
12
o'clock position
is
a great starting point.
EXAMPLE:
If
you
adjust
the
Subsonic
to
25Hz,
the
amplifier will
not
play frequencies
below
25Hz
but
will
play frequencies from 25Hz
to
the
chosen
Low
Pass
frequency.
8assEQ:
This setting
is
a fixed
bass
boost
at
45Hz
that
is
variable from 0- I
OdB.
This feature provides impact
to
your
bass,
but
if
not
adjusted correctly,
it
can be
over used
and
cause damage
to
your
subwoofers
and
amplifiers.
It
is
best
to
slowly
turn
this setting clockwise until
the
desired
punch
is
felt.
it
is
not
recommended
to
exceed
the
12
o'clock position unless listening
at
a
low
volume
or
a
low
recording quality
as
this can result in
high
distortion and
possibly clipping.
Low
Pass:
The
Low
pass
control acts
as
a ceiling
and
doesn't
allow
frequencies
to
the
right
of
the
desired setting
to
be reproduced. The
12
o'clock position
is
a
great starting point.
EXAMPLE:
If
you
adjust
the
Low
Pass
to
BOHz,
the
amplifier will
not
play frequencies above 80Hz
but
will play frequencies from
80Hz
to
the
chosen Subsonic frequency.
Phase:
The variable
Phase
adjustment allows
you
to
change
the
relative time
that
the
waveform meets
your
ear. With standard subwoofer installations
where
the
subwoofer
is
behind you,
the
Phase
should generally be
at
O.
When
subwoofers
or
woofers are in the kick panels
or
door
panels,
the
Phase
adjustment
is
useful in delaying
the
timing
of
the
wave
meeting
your
ear
by
adjusting
the
potentiometer
to
I
BO
degrees.

Control
Setup:
Ensure
that
the
Level
is
turned completely
to
the
left prior
to
turning
the system on. Next
you
should insert a
CD
or
cassette
that
you
are familiar
with
to
use
as
a reference,
and
turn
the
head
unit
volume control
to
about
80%
of
its full setting. The system sound level
will
of
course be very low,
and
the
following
procedures will help
you
to
match
the
amplifier
input
sensitivities properly
to
the head
unit
output
signal level.
It
is
important
to
match
the
amplifier LEVEL
input
sensitivity
to
the
Radio/CD
output
sensitivity. This can
be
located in
the
Radio/CD manual.
If
the
Radio/CD
output
sensitivity
is
2 volts,
then
adjust
the
amplifier LEVEL
input
to
2 volts.
If
you
are
not
sure
what
the
Radio
output
sensitivity
is,
follow
these general
guide
lines:
Turn
the
level control
up
slowly, till
you
hear distortion, then back
off
a
few
degrees
on
the
control.
If
at
any
point
your
amplifier goes
into
protection,
you
will need
to
turn
the
Level
to
the
left a bit
and
then
try again.
If
you
reach a
point
where
the
output
does
not
increase, stop
turning
the
Level
control
to
the
right
as
the
amplifier/subwoofer combo has reached its maxx
output
in this application.
