Connection variant no. 2
(Additional woofer for an existing hi-fi system)
Connect the subwoofer to your amplifier at the „B“ loudspeaker outputs. The connections of
the existing speakers remain unchanged. Having connected the subwoofer, you must then
activate the „B“ loudspeaker outputs; your amplifier’s operating manual will tell you how to
do this. Put your subwoofer into operation as described under „Starting up“.
This operating mode can only be used if you can activate the speaker outputs A & B on your
amplifier simultaneously. Please consult your amplifier's operating manual accordingly.
For operation with a surround sound amplifier, please follow the instructions given in "Con
-
nection variant no.1".
Connection variant no. 2
(Differences of models cause a different position of the operating elements.)
Connection variant no. 3
(Subwoofer in a preamp/output amp combination: not possible on all subwoofers)
If your system consists of a preamp/power amp combination you can, connect the subwoofer
to the preamp’s output by means of a cinch cable. To do this, use the cinch sockets marked
„LOW LEVEL IN“. Also using a cinch cable, connect up your output amp to the subwoofer at
the cinch socket „LOW LEVEL OUT“. If your preamp has 2 pairs of output sockets you can
leave the direct connection between preamp and output amp as it is and simply connect the
subwoofer to the preamp’s second cinch output; there is then no need for the subwoofer to be
connected to the power amp. In both these cases there is no need to use loudspeaker cables
for the connections. Put your subwoofer into operation as described under „Starting up“.
Connection variant no. 3
(Differences of models cause a different position of the operating elements.)
Connection variant no. 4
(Subwoofer in a surround system)
If your surround amp or receiver has a subwoofer line output (Sub Pre-Out), you can use this
by connecting the subwoofer to this socket by means of cinch cable (Connection variant no.
4a or 4b). If your surround amp does not have an output of this type you will have to connect
up the subwoofer as described under „Connection variant no. 1“.
Having connected up your subwoofer at the subwoofer line output of your digital surround
sound amplifier, you must now configure the amplifier's bass management as follows:
Subwoofer: yes
Front, center, rear: large /small (depending on size)
Connection variant no. 4a
(Differences of models cause a different position of the operating elements.)
