SETTING
UP
SYSTEMS AFTER INSTALLATION FOR BEST PERFORMANCE
General:
At
this
pointyou are ready to
get
more
specific
on the settings for your amplifier.
HIgh Pass:
-When
in
Hi
Pass
operation,
this
setting
acts
as
a
low
frequency cut offfor your
system
reproduction. The point thatyou set it
at
cuts
off anyfrequencies from reproduction
beyond this point. The
12
o'clock position
is
a greatstarting point.
EXAMPLE:
If
you
adjust
the
High
Pass
to
100Hz.
the
amplifier
will
not
playtrequencies
below
100Hz
but
will
playtrequencies
trom
100Hz to
the
chosen
Low
Pass
trequency.
-When
in
Low
Pass/Bandpass
operation, this setting
acts
as
a
low
frequency cut offfor your
system
reproduction aka
Subsonic
Filter. The point thatyou set it
at
cuts
offany
trequencies
trom
reproduction beyond this point. The
12
o'clockposition
is
a greatstarting point.
EXAMPLE:
If
you
adjust
the
High
Pass
to
25Hz.
the
amplifier
will
not
play
trequencies
below
25Hz
but
will
playfrequencies from 25Hz
to
the
chosen
Low
Pass
frequency.
-When
in
Flat/Full operation, the High
Pass
crossover
is
bypassed.
BassEQ:
This
setting
is
a
fIXed
bass
boost
at
45Hz that
is
variable from
0-1
OdB.
This
feature provides impact to your
bass,
but if
not
adjusted correctly. it can
be
over used and cause
damage toyour
speakers
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 quali1y
as
this can result in
high
distortion
and
possibly clipping.
Low
Pass:
The Low
Pass
control
acts
as
a ceiling and doesn't allowfrequencies to the right
of
the desired setting to be reproduced. Turning the potentiometerall the
way
to the right
is
a greatstarting point.
EXAMPLE:
If
you
adjust
the
Low
Pass
to
120Hz.
the
amplifier
will
not
playfTequencies above 120Hz
but
will
playfrequencies from 120Hz
to
the
chosen Hi
Pass
or
Subsonic trequency.
-When
in
Hi
Pass
operation,
this
setting
is
bypassed.
LevelControl Setup:
Ensuse
that the level
is
turned completely to the left prior to turning the syetem on. Nextyou should insert a CD or
cassette
thatyou 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 bevery low.
and
the
following
procedures
will
help
you
to match
the
amplifier
input
sensitivities properlyto
the
head
unit
output
signal level.
It
is
important to match the amplifier
LEVEL
input sensitMty to the Radio/CD output
sensitivity.
This
can be located
in
the Radio/CD manual.
If
the
Radio/CD
output
sensitivi1y
is
2 volts.
then
adjust
the
amplifier LEVEL
input
to
2 volts.
If
you
are
not
sure
what
the
Radio
output
sensitivi1y
is.
follow
these general guidelines:
Turn the level control
up
SlOWly,
till you hear distortion, then back offa
few
degrrees on the control. If
at
anypointyour amplifier
goes
into protection, you will need to turn
the level to the left a bit and then
try
again. Ifyou reach a point where the output
does
not increase, stop turning the level control to the righe
as
the amplifier/speaker
combo
has
reached
its
maxx output
in
this
application.

by
turning

audible.
and

olf
some.
Now
adjust
the
level control
for
the
highs
or
tweeter channels in a 2
way
active system. to balance
the
highs to lows.
In a 3
way
active
system,
match the midrange level to the
bass,
and then the highs to the midrange and
bass.
It may
be
necessary to perform a
few
iterations
of
the midrange
and highs level control settings to achieve a satisfactory sound balance.
