Controls and connections
    MAINS SWITCH / MAINS SOCKET:
The mains switch acts as a mains isolation switch, i.e. it
switches the sub-woofer off permanently. If you will not
be using the speaker for a long period, the mains switch
should always be switched off, or the mains lead
disconnected.
    ON / AUTO / CTRL
This switch is used to set the operation mode of the
subwoofer.
'ON' setting
If the switch is set to the 'ON' position, the sub-woofer
remains switched on permanently, regardless of the
input signal.
Note:
The 'ON' setting is suitable for use with a switched mains
power supply socket (e. g. surround receiver with
switched mains outlets).
'AUTO' setting
The speaker switches on automatically as soon as a
music signal is present.
'CTRL' setting
The speaker switches on automatically as soon as a
switching voltage is present at the switch input CTRL or
of the SC
LINK socket.
    CTRL
Input for control voltage (trigger voltage) to switch the
subwoofer on and off. The voltage level of the trigger
voltage should be in the range of +5 V . . . +20 V.
    SC LINK (DIN IN) *)
Input socket for  units with an SC LINK output. In
addition to the music signal, this socket passes a
switching signal for the automatic power-on circuit, and
control information for the internal crossover filters.
Note:
Even machines not fitted with a  SC LINK output can
switch the sub-woofer on and off using this socket,
provided that they generate a switching voltage (+5V . . .
+15V). In this case please contact the
 Service
Department for a suitable adaptor lead (see also the
section 'Specification' for the pin assignment of the 8-
pin SC
LINK DIN socket).
    LINE INPUT (CINCH IN) *)
If the signal to the sub-woofer is to be supplied by a pre-
amplifier, connect the pre-amplifier outputs to these input
sockets.
These sockets are also used to connect the speaker to
the sub-woofer output of a surround decoder. If only one
output is available, it is sufficient to connect this to one of
the sub-woofer's inputs (e.g. the left one), as the two
inputs are identical.
*) Note:
The input sockets LINE INPUT and SC LINK must not be
used simultaneously! Please decide which type of
connection you wish to use (see section 'Wiring
variants').
    LEVEL
This adjustor is used to regulate the amplification of the
active unit. Adjust the level to set the bass output to
match that of your satellite loudspeakers.
