For
optimum surround performance, speaker
placement
and matched frequency response is very
important.
Five
identical
speakers positioned three across
the front
and
two in
the rear provide the best
performance.
lf it is
not
possible
to
use
a center speaker that is identical to
the
other speakers then choose
a
speaker that closely
match-
es
the high and midrange performance
of
the
left
and right
front
speakers.
A subwoofer
system
further enhances
sys-
tem
performance.
The Left and Right
f
ront channel speakers should
be
mounted in the front doors or the
dashboard.
The left
and
right surround channel speakers should be mounted
in the
rear
of the car as close to the back
corners
as
possible.
Reflecting
the
radiated sound from
the back
speakers
off
the
rear
of the
car
interior
and
rear
window is preferable
to
aiming them directly forward.
Some
hatchback vehicles
are
exceptions
to
this
rule.
The
center front channel speaker should be mounted
in
the
center area of the dashboard and need not have
bass
response below
the
25O
Hz factory
hi
pass crossover
set-
ting.
lf
the center channel speaker
has
limited output capa-
bility
at
the 250 Hz
hi pass
setting, then
it
may
be
neces-
sary
to
add
an
additional passive hi pass crossover for
the
smaller center channel speaker. This additional passive
hi
pass crossover
can be built by placing an appropriate
value
capacitor
in
series
with the
smaller
center
channel
speaker.
Note: ln unusual cases a qualified installer may wish
to
reduce center
vs. left and right front channel
separation
depending on power handling and the location of
the
center channel speaker.
The
factory setting of the
CSP-1
is
for maximum center
to
front channel separation and
is ideal
for most installations. The
CSP-1
front
to center
channel
separation
can be adjusted if
necessary
using the
proce-
dure that follows.
The
Center
Front
Separation potentiometer is located under
the bottom cover, which can be removed using the
pro-
cedure given in the "How to replace a resistor
module"
section
of this manual. The potentiometer adjustment
is
located in the upper right
corner of
the circuit board
near
the "LR" output
RCA
jack and is labeled
"CF Sep"
and
'R70". At the full clockwise or max position the
control
causes
all
mono signal
to be
sent
to the "Center
Front"
channel
output
-
this is the factory setting for
maximum
separation
and
is ideal for most
installations.
At the counter
clockwise position the control sends all mono
signal
equally
to
both the
left
and right front outputs and
no signal
to the center front output. This control should only
be
adjusted
by a knowledgeable
installer
in
unusual
installa-
tions but typically should
be left at the factory setting
for
maximum separation. There are no other installer
adjustable controls inside the
CSP-1 case.
Subwoofers
can be
mounted on the left
and right
sides
of
the car
in
the kick panels, doors, or
rear
deck. An excellent
combination
is
to use
smaller stereo subwoofers
mounted
in the
forward
area
and
a
large mono subwoofer
mounted
in
the
rear.
