The
chart only
shows
standard
resistor module
values.
Many
of these values are
available from
your
Harman
Kardon
car audio
dealer,
As an
alternative
they can
also
be
obtained
from
electronic components
dealers.
Due
to the
nature
of
surround sound processing
we
rec-
ommend
against the
use
of
crossover frequencies below
150 Hz
and above 300
Hz on
the
"Hi Pass" crossover.
HOW
TO REPLACE
A
RESISTOR MODULE
To
replace a
resistor
module,
use the
following
procedure:
1.
Turn
off the
car
audio
system. This
will
prevent
loud
"pops" that may damage
some speakers.
2.
Touch one of the input or output jacks with
your
finger
to
eliminate
any static charge.
3.
Remove
all of the power, input and output connectors
and
jacks.
4.
Remove
the mounting screws from the
CSP-1
and
remove
the
unit from the vehicle.
5.
Take
off the
bottom
cover of the
enclosure
by
first
removing
3
screws from
the input signal end plate,
2
screws from
the
bottom corners
of
the output
signal
endplate, and
3
screws from each blank side
of
the
case.
Next slide
the
bottom
cover
backwards until
the
endplate
clqars
the
input
jacks and then
lift
the
cover
off
.
Find
the appropriate
resistor module
on the
circuit
board. They
are marked
'Hl
PASS"
and 'LOW
PASS'
and are located on the end of the circuit board
near
the input
RCA
jacks.
Using
a
small screwdriver, slowly and gently pry
the
module
up
first
at
one
end
and then
at
the other
end.
Repeat
prying
up
each end
until
the module
is
loose
and
can
easily be taken away
by
hand.
Be
careful
not
to bend the
pins.
lnsert
the new
resistor module. They
are
srymmetrical
and cannot
be
inserted backwards. Gently push
the
module
firmly
into
the socket. Be careful
not
to
bend
the
pins.
Re-install
the
bottom
cover
plate.
Re-mount
the
CSP-1
using
the
four mounting
screws.
Reconnect
the
power,
input and output
connectors
and jacks.
Turn on the
audio system
power.
