Connection variant no. 2
(Subwoofer in a preamp/output amp combination)
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/LINE“. Also using a cinch cable, connect up your output amp to the subwoof-
er 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 these case 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
(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)
In these case there is no need to use loudspeaker cables for the connections. Put your sub-
woofer into operation as described under „Starting up“.
Connecting up
Please connect the device using the network cable supplied to the mains socket shown below.
Before connecting up the subwoofer to your hi-fi or surround system, make sure that the unit
and all system components are switched off, i.e. the pilot lights should all be off.
Connection variant no. 1
(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.
