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

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.
