Setting up the AV receiver
For your home cinema system LT2 with active sub-
woofer, select the "small" or "normal" (not "large")
setting in the bass/speaker setup of the AV recei-
ver for the satellites – this guarantees that the
satellites can be fully loaded and the subwoofer
and front speakers harmonise perfectly with
each other.
The subwoofer must be set to "On" in the bass/
speaker setup on the receiver. The appropriate
cut-off frequency in this set-up for the LT 2 is 110
Hz (100/120/150 Hz are also possible).
Setting up the subwoofer
When operating the system on the AV receiver, the
frequency control on the subwoofer/remote con-
trol must be set to "Maximum" = "140 Hz" becau-
se the cut-off frequency is set by the AV receiver
– its settings are dominant.
Modern AV receivers set the subwoofer phase
correctly when adjusting the distance of the
subwoofer from the listening location during
"speaker setup" – so the phase controller on the
subwoofer itself should be left in the "0°" positi-
on. For older AV receivers or appliances without
an option to compensate for the distance of the
subwoofer, the following applies:
With the phase controller, you can adjust the sub-
woofer to the satellites such that the speaker
membranes vibrate in the same direction in the
cut-off frequency range. If the phase is set incor-
rectly, the bass may be weakened or cancelled.
For a subwoofer position between the front spea-
kers, we recommend "0°" (grey field in the illus-
tration on Page 8), for a position near the liste-
ning location "180°" . If the subwoofer is in another

location, the "180°" setting can balance out the
reduced bass playback. Set the phase controller
appropriately to get the strongest bass playback.
The volume setting of the subwoofer may be
slightly different when playing back music com-
pared with home cinema sound, depending on the
recording quality and mixing. Whereas a massive
bass element predominates on DVDs with lar-
ge quantities of special effects, for music the
desired level is sometimes not reached (especially
if the set has been set up for ideal DVD playback).
In this case, the user's own taste is the main de-
termining factor in finding the right compromise
between the two sources.
This is how you can gradually find the best volume
for the subwoofer:
We do not recommend selecting an automatic
setting for the subwoofer using the integrated
calibration computer (if the receiver has such)
but rather setting the subwoofer in the bass/
speaker setup to a high value between +8 and
+12 dB (around setting "55" on the subwoofer).
This guarantees operation of the auto on/standby
mode; then you can determine the ideal level for
the subwoofer by carrying out listening tests.
Subwoofer remote control
Volume
This sets the subwoofer's volume. Increase the
volume using the "+" button and decrease it
using the "–" button.
Frequency
Here you can align the subwoofer's cut-off fre-
quency with the satellite speakers. For operation
on the AV receiver press the "140 Hz" button. The
display on the front of the subwoofer then shows
"14" .
