Connect the output socket of the signal source (e.g.
PA 820 M) to the sub-woofer's DIN IN input socket
using the SC
LINK
lead (8-pin DIN lead).
The signal to control the sub-woofer's internal filter is
passed via the SC
LINK
lead. The filter is now switched
on or off by the signal source as required.
The control voltage for the automatic power-on circuit is
also transferred via the SC
LINK
lead.

First connect the active speakers to the desired signal
source using a 5-pin or 8-pin DIN lead as described in
the TALIS operating instructions.
Connect the output socket of the 2nd active speaker to
the DIN IN input socket
of the sub-woofer using an
SC
LINK
lead.
The sub-woofer's internal crossover passes the low-
frequency part of the signal to the sub-woofer.
If the active speakers are switched on and off using a
control voltage, the control voltage is also passed to the
sub-woofer via the SC
LINK
lead. This triggers the sub-
woofer's automatic power-on circuit.
Notes:
If you use this method of connection, you must select the
option 'Full range' for the front loudspeakers when
setting up the surround decoder. This is carried out at
the loudspeaker configuration stage.
In this case the 'FILTER' switch on the TALIS loud-
speakers should be set to the 'ON' position. This avoids
passing the low-frequency part of the signal to the TALIS
units, avoiding undue stress on the speakers, and
allowing them to operate cleanly at higher levels.
