Adjusting
X-Over
and
Switching
the
Phases
This section describes how to adjust X-Over. Before working
on
this,
refer to
"About the Crossover
(X-Over)"
(page
48).
Note on adjusting the subwoofer
·
If
the subwoofer
is
installed on the rear deck, setting a gentle
LPF
slope (for example 6 dB/ oct.) makes the sound localization
more to the
rear.
This can also
affect the acoustic
localization
of
the front.
Note on adjusting the high range
Depending
on
the
speaker, inputting
low
frequen
cy
component
signals
(about
2 kHz or
less)
with the
HPF
adjustment
could
result
in
distortion.
If
distortion occurs, set a steep slope
(for
example
30
dB/oct.).
Adjust
so
that the
mid
and
high range sounds
do
not
separate.
Normally
use with the
LPF
turned
off.
If
the
high range
is
too
strong,
we
recommend adjusting for a
gentle slope.
Note on adjusting the low range
When
a subwoofer
is
connected and you are using a speaker
with a
low
range of under 10 or 12
em
(3-15/16"
or
4-3/4"),
setting the
low
range
HPF
to "OFF"
can result
in
distortion
when
low
frequency components are input.
If
so,
set the
H.
P.F.
slope to a value suited for
the
speaker's
frequency response.
