Please
consider
that
the
fader-
and
balance
control
of
the
head
unit
have
the
same
effect
on
channels
3
and
4
as
on
channels
1
and
2.
4-channel
mode:
When
operating
headunits
with
two
stereo
outputs,
all
four
speaker
outputs
are
supplied
with
the
corresponding
input
signal.
Channel
5
(subwoofer
output)
is
supplied
by
a
sum
signal
of
the
4
input
signals.
5-channel
mode:
In
this
mode
all
RCA
inputs
must
be
connected
(all
five
channels).
As
channel
5
has
a
stereo
input,
both
should
be
used.
In
case
only
one
input
is
con-
nected,
the
sensitivity
must
be
adjusted.
When
using
the
high
level
inputs
in
the
5
channel
mode,
the
5th
RCA
channel
must
be
connected.

channel

To

bandpass.
When
the
switch
is
set
on
HPF
(highpass),
the
exact
crossover
frequency
for
highpass
can
be
adjusted
with
control11.
In
position
FULL
(fullrange)
the
internal
frequency
cross-
over
is
not
active.
In
position
LPF
(lowpass)
highpass
is
always
active.
This
means
that
a
bandpass
is
formed
in
any
case.
When
using
control
17
for
highpass
and
control
18
for
lowpass
any
bandpass
between
15
Hz
and
4000
Hz
can
be
adjusted.
Caution!
To
avoid
a
loss
of
sound
pressure,
make
sure
that
the
crossover
frequencies
are
seperated
by
2
octaves
when
adjusting
the
bandpass.
The
adjusted
lowpass
frequency
must
always
be
higher
than
the
highpass
frequency!
This
means
for
example:
If
the
lowpass
signal
is
set
on
320
Hz,
the
highpass
should
be
lowered
by
2
octaves
to
80
Hz.
(1
octave
=
double
frequency
or
half
frequency).
