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.
