RS2.1200
INTERCONNECTION EXAMPLE 2-Channel Mode: 1x Mono Subwoofer bridged
RCA & Speaker wiring:
•
Connect
the
RCA
lineouts
of
the
headunit
with
the
RCA
jacks
LINE
INPUT
of
the
amplifier
with
appropriate
high-value
RCA
cables.
If
your
headunit
is
equipped
with
a
additional
subwoofer
lineout
(SUB
OUT),
it is
recommended
to
use
this lineout.
• Connect the subwoofer with the speaker outputs (SPEAKER OUTPUT LEFT&RIGHT + Mono bridged- ) by using appropriate wires.
• Ensure by any means, that the total impedance load
of
the channel-pair
is
not lower than 4 ohms.
Too
low impedance cause high
temperature and will shut down the amplifier operation.
•
Always
ensure
the
correct
polarity
of
the
speakers.
The
interchange
of
plus
and
minus
cause
total
loss
of
bass
playback
and
could
damage
the
speakers.
Caution!
Do not
connect
speaker(-)
to the ground
or
vehicle's
chassis.

• In
the
mono/subwoofer
mode
the
X-OVER
switch
must
set
to
the
LPF/BPF
position
(Lowpass/Bandpass
mode),
thereby
the
higher
frequencies
will
be
eliminated.
The
cut-off
frequency
ist
adjustable
with
the
LOW
PASS
controller
and
should
be
set
between
40Hz
to
500Hz
,
depending
on
the
size
of
the
subwoofer.
LEVEL CONTROLLER
•
Turn
the
LEVEL
controller
of
the
amplifier
to
the
6V
position.
•
Turn
the
volume
controller
of
the
headunit
to
80
-
90%
of
its full setting.
•
Turn
the
LEVEL
controller
clockwise
until
you
hear
some
distorlion.
•
Then
turn
back
the
LEVEL
controller
slightly
until
you
hear
a
cleaner
sound.
BASS BOOST CONTROLLER
•
The
BASS
BOOST
controller
adjusts
the
bass
enhancement
between
0db
and
+
12dB.
• A
too
high
bass
boost
may
cause
clipping/distortion
and
damage
on
the
loudspeakers
and
also
may
harm
your
hearing
abilities.
Use this controller carefully!

HP/LOW
PASS
CH1/2&CH3/4
HP PASS (High Pass)
Controls the frequency response
of
your
speakers downwards. The Cut-off frequency is continously variable from 50Hz up to
400Hz
LOW
PASS
(LowPass)
Controls the frequency response
of
your
speakers upwards. The Cut-off frequency is continously variable from
50Hz
up to
400Hz
If the
X-OVER
- Switch is
set
on LP -position, so the HP PASS- controller is activated as Subsonic-Filter, who eliminates the lowest frequencies to
protect the speakers from damages.

The built-in electronic diagnostic protection saves the
amplifier and speakers from serious damage. If the red LED
lights up due to overheating, let the amplifier coold down a
while a turn it on again.
If
the red light is still lighting up, ensure that all connections,
especially the speakers are correct and
not
shorted.
If
the
amp
is still in protection mode, try to restart the
amplifier without
any
speaker
or
RCA
wires.
If
the green light is now lighting up, re-check again all
speaker- and RCA-connections, to ensure correct
connection.
