Remote Connection
KW 4V8
Run cables with small diameter from the car radio or CD-player-remote terminal to the preamplifier and attach to
the white cable „REM IN“ (
3
). Lay the blue cable “REM OUT” (
4
) to the amplifier and connect with the remote
input on the amplifier.
When switching the car radio/CD player on and/or off the amplifier is switched on and/or off over a soft muting
with a time delay of approximately one second.
Switching On / Control Function with LED
The powering on of the preamplifier is indicated by the green LED “PWR” (
21
). The preamplifier switches on with
a time delay of approximately one second. Uncontrolled motion of the loudspeakers is suppressed by this soft start
when switching on the amplifier.
„INPUT“ Connection: Preamplifier Input
Via RCA Cable from Pre-Out on Car Radio / CD-Player:
The output signal of the car radio/CD playler is fed by means of a RCA cable to RCA sockets „INPUT FRONT“
(
6
) R (right) and L (left) and „INPUT REAR“ (
7
) R (right) and L (left). Input volume is regulated by the
Potentiometer „GAIN“ (
15
) for „FRONT“ and Potentiometer
„GAIN“ (
20
) for „REAR“, and the „SENSITIVITY“
(
10
) switch from 400 mVolt (MAX) to 4 Volt or 8 Volt (MIN). The „LEVEL INPUT“switch (
9
) should remain on
position „LOW“.
For subwoofer operation the preamplifier can be supplied by only one input signal, „INPUT REAR“ (
7
)
R (right) or L (left), as preferred. For this the „MONO“ switch (
14
) should be set to „ON“. This simultaneously
activates the phase shifter. The phase of the „REAR“ channels can be adjusted from 0° to 180° by the
Potentiometer „PHASE“ (
19
).
Direct from Loudspeaker-Outputs of Car Radio:
The loudspeaker output signal of the car radio is fed by means of a high-level adaptor cable (Art. No. 273031 2m,
273032 5m) at the RCA sockets „INPUT FRONT“ (
6
) R (right) and L (left) and „INPUT REAR“ (
7
) R (right) and
L (left). The input volume is adjusted with the Potentiometer „GAIN“ (
15
) for „FRONT“ and Potentiometer
„GAIN“ (
20
) for „REAR“ and the „SENSITIVITY“ (
10
) switch from 400 mVolt (MAX) to 4 Volt or 8 Volt
(MIN). The „LEVEL INPUT“ switch (
9
) must remain on the „HIGH“ setting.
Caution:
Use of
different RCA cable lengths could potentially lead to potential differences. A variation in
lengths can cause a ground loop, resulting in unpleasant generator distortion.
Do not lay RCA cables
parallel with power cables, in order to prevent distortion couplings.
