The LINE IN sockets     on the sub-woofer are con-
nected to the output sockets of the pre-amplifier using
Cinch leads.
The speaker's internal crossover passes the low-
frequency part of the signal to the sub-woofer.
Use without control voltage:
The automatic power-on circuit is triggered by the pre-
amplifier signal.
* Use with control voltage (optional):
If the pre-amplifier features a control voltage output, this
control voltage is passed to the SC
LINK socket     via
an adaptor lead. This triggers the automatic power-on
cir-cuit.
The  P 1220 R pre-amplifier supplies a control
voltage at the CRTL OUT socket.

The Cinch lead carrying the SUB OUT signal from the
surround decoder is connected to one of the sub-
woofer's LINE IN sockets
   .
Since the SUB OUT signal is filtered in the decoder, the
Filter switch
    must be set to the 'FILTER OFF'
position.
Use without control voltage:
The automatic power-on circuit is triggered by the
SUB OUT signal.
* Use with control voltage (optional):
If the surround decoder features a control voltage output,
this control voltage is passed to the SC
LINK socket    
via an adaptor lead. This triggers the automatic power-on
circuit.
The  DD 1210 R and DD 1510 R surround decoders
supply a control voltage at the 5.1 OUTPUT socket.
