b.
No
inductors
and
only
a
few
small
capacitors
are
used
in
active
dividing
networks.
Therefore,
large
phase
shifts
and
their
associated
problems
are
eliminated.
c.
Different
components
of
the
speaker
system
are
driven
by
separate
amplifiers.
These
amplifiers
act
as
isolators
and
prevent
any
interaction
and
intermodulation
between
the
different
drivers.
Tweeters
will
be
safe
from
high
fre-
quency
by-products
of
a
clipping
subwoofer.
d.
Level
imbalances
between
different
speakers
are
over-
come
very
easily
by
adjusting
the
output
level
control
of
~
each
band.
Because
‘only
the
pre-amp
input
“level”
to
amplifier
is
changed,
there
is
no
loss
in
efficiency.
e.
The
Butterworth
filters
used
in
all
Alpine
active
dividing
networks
have
extremely
low
ripple
and
excellent
fre-
quency
response
characteristics.
Response
non-linearit-
ies
are
virtually
eliminated.
Wiring and Set-up
AUDIO CONNECTIONS and SET-UP:
To
reduce
chances
of
vehicle-induced
noise
generated
by
radiation
from
other
electrical
equipment
entering
your
sound
system,
use
audiophile
quality
RCA.extension
cables
when-
ever
possible.
.We
recommend
Alpine’s
gold
plated,
triple
shielded
wires
and
accessories
for
best
results.
These
ac-
cessories
feature
a
copper
braid/aluminum
foil
shield
which
is
completely
isolated
from
the
signal
path.
This
independent
shield
will
block
any
radiated
noise
from
entering
the
audio
signal.

A
great
deal
of
time
and
labor
will
be
saved
if
you
invest
in
high
quality
signal
cables
before
the
system
is
in-
Stalled,
rather
than
upgrading
after
a
noise
problem
sur-
faces.
Route
the
sound
system’s
audio
cables
and
power
cables
Separately,
as
far
away
from
each
other
as
possible,
in
order
to
minimize
chances
of
interference
from
high
current
power
wires
(such
as
power

being
picked'up
by
the

The
Alpine’s
3672
is
a
very
versatile
and_flexible
piece
of
equipment.
To
achieve
this
high
degree
of
versatility,
it
was
necessary
to
include
many
instailer-adjustable
controls.
that
need
be
set
for
each
different
mode
of
operation.
After
the
3672
is
mounted
properly,
it
should
be
set
up
as
described
below.
We
recommend
using
Alpine
4410,
4422
or
4452
extension
cables
for
high
quality,
reliable
and
long-last-
ing
connections.
’ @ INPUTS:
1.
If
the
head
unit
has
separate
front
and
rear
pre-amp
outputs,
connect
each
one
using
an
extension
cable
to
the
front
and
rear
inputs
of
the
3672.
Set
the
Input
Selector
(page
7,
item
24)
to
the
2-input
mode.
2.
Ifthe
head
unit
has
a
single
pre-amp
output,
connect
it
to
the
CH
3/4
input
of
the
3672
using
an
extension
cable.
Set
the
Input
Selector
(page
7,
item
24)
to
the
1-input
mode.
