Cable connection
• Connect INPUT
of
the amplifier to the head unit line output with good quality
RCA
cables.
By
connecting the
RCA jacks
OUTPUT
with a additional amplifier, a full range signal will be
provided to the amplifier.
• Connect the speakers with the terminal block (CH1 +/- und
CH2
+/ -
SPEAKER)
and
(CH3 +/- and
CH4
+/ -
SPEAKER)
of
the amplifier.
•
The
minimum final speaker impedance must not be
below
2 Ohm
per
channel. Too low
speaker loads result in too high heat dissipation and
may
cause the amplifier run into
protection.
• Please observe
speaker
channel and polarity as printed
by
the
speaker
terminal block.
Incorrect phasing
of
the speakers results in total loss
of
bass response.
Caution
Please avoid to connect speaker(-) to the ground
or
vehicle chassis.
X-OVER- Switch & Control CH1/2 and CH3/4
•
If
larger than 20 cm speakers are used, the "FULL" position is recommended.
• For all smaller speakers (8.7cm - 16cm) the "HP"- Position (HIGH PASS) is recommended, which
eliminates the lowest frequencies and protects the speakers from damage. Set the crossover-frequency
between
50Hz
-
400Hz
, depending on the size
of
the installed speakers. The Highpass adjustment can be
done with the HIGH PASS - Control. In this configuration the
LOW
PASS - Control is not in use.
LEVEL INPUT - Control CH1/2 and CH3/4
• Turn the LEVEL
INPUT
- Control on the amplifier
to
"6V" position.
• Turn the head unit volume control
to
about 80-90%
of
its full setting.
• Turn the LEVEL
INPUT
- Control clockwise until you
hear
some
distortion.
• Then turn
back
the LEVEL
INPUT
- Control slightly until you can
hear
clean sound.
BASS BOOST CH1/2 and CH3/4
• Turn the BASS
BOOST
- Control into "0dB" - position.
