AMPLIFIER
SELECTION
Unlike many
other center channel
systems,
the
CSP-1
cen-
ter channel should
be
powered with an amplifier that is
of
equal
or
greater power rating
to
the amplifier used on
the
left and right front channels. ldeally, the rear channel
speakers should also be powered
at
the same level
as
the
front channels. The subwoofer amplifier should
be
pow-
ered as appropriate for the amount of bass output
desired
in
the
installation.
2/4 INPUT SWITCH
Set
the input switch to either the 2 or 4 input
setting
depending on how
many RCA inputs are
connected
from
the head
unit
to the
CSP-1.
INPUT GAIN SWITCH
Set
the lnput
Gain Switch
to
normal.
lf the output
level
of
the processor
seems
low during
latter listening tests,
this
switch
may
be changed to
the high
gain
setting
for
better
matching,With
the output
level of the
head
unit.

bwrrcn
The subwoofer switch should be turned on only in
installa-
tions which have a subwoofer. The subwoofer switch
engages a
high
pass crossover
on
the four corner
channel
speakers. This allows bass frequencies
to be
reproduced
only by the
subwoofers attached to
the left, right or
mono
subwoofer outputs
of
the
CSP-1.
AMPLIFIER LEVEL ADJUSTMENTS
Before
adjusting speaker
levels,
center
the left-right
and
front-back balance controls on the tuner/cassette
or
tuner/CD. Set
the CSP-1 bypass control to the bypass
mode.
Play
a well-recorded
stereo
source
arrd
adjust
the
amplifier input levels andlor
CSP-1
output levels for
a
roughly even
channel balance,
left-right
and
frontback.
Re-adjust
the amplifier input
levels
and
CSP-1 output
levels
as
necessary to obtain the best signal
to
noise
per-
formance. As
a
general rule the input level controls on
the
amplifier should be set as
low
as possible while
still
providing
adequate volume
levels
when the CSP-1 output
levels
are set
at
near
their
half
way point.
