Setting up the AV receiver 

To take full advantage of your LT 3 PE Home Thea-
tre System with Active Subwoofer, set the “Speak-
er  Setup”  section  (Bass  Management/Speaker 
Management)  of  your  AV  receiver  to  “small”  or 
“normal” (not “large”) for the five satellite speak-
ers. This ensures that each speaker receives the 
right  amount  of  signal,  and  that  the  subwoofer 
and front speakers have matching volumes. Also 
in  the  receiver's  “Speaker  Setup”  section (Bass 
Management and/or Speaker Management), make 
sure the subwoofer is set to “On”. Set the crosso-
ver frequency for the Columa 900 system to 100 
Hz (or 120 Hz.)*

Setting up the subwoofer 

If your system is based around an AV receiver, set 
the  subwoofer's  Low  Pass/Full  Range  switch  to 
“Full Range”; the AV receiver automatically deter-
mines the crossover frequency. Modern AV receiv-
ers  determine  the  subwoofer's  phase  automati-
cally. This happens within the receiver's “Speaker 
Setup”  utility,  which  analyses  the  distance  be-
tween  the  different  speakers  and  the  listening 
spot. For this to work correctly, the subwoofer's 
own phase switch needs to be on “0°”. 

If  your  system  uses  an  older-model  AV  receiver 
or another type of amplifier without a setting for 
the subwoofer distance: 
The “Phase” control lets you adjust the subwoofer 
to the satellite speaker so that the membranes 
of all the speakers vibrate in the same direction 
(“phase”)  when  reproducing  signals  around  the 
crossover  frequency.  If  the  phase  is  set  incor-
rectly, this may cause a reduced bass response or 
even bass cancellations. 

If the subwoofer is positioned between the front 
speakers,  we  recommend  a  phase  setting  of 
“0°” (grey area in the diagram on page 8); if the 
subwoofer  is  positioned  closer  to  the  listening 
spot, a phase of “180°” may be more appropriate. 
Similarly, the “180°” setting may help to eliminate 
bass cancellations if you position the subwoofer 
in other areas of the room. Always set the phase 
control to the position where the bass response is 
best. In order for the subwoofer's phase switch to 
be active, the Low Pass/Full Range switch needs 
to be set to “Low Pass”.

The subwoofer's output setting may vary slightly 
depending  on  usage,  e.g.,  home  theatre  sound 
system  or  music  playback.  Whereas  an  action-
packed  DVD  typically  contains  very  defined  sub 
bass  signals,  many  music-only  sources  do  not. 
This is especially noticeable if your system is cali-
brated for optimum DVD playback. To find the best 
compromise  between  differing  sound  sources, 
use your own subjective judgement. 

Our  recommendation  is  to  determine  the  best 
subwoofer volume gradually over time. 
Avoid  configuring  the  subwoofer  volume  auto-
matically via your AV receiver's integrated room 
analysis  computer (advanced  receivers  only).  In-
stead,  set  the  subwoofer  level  provided  in  the 
Bass Management/Speaker Management section 
(“Speaker Setup”) to a high value, such as +8 to 
+12 dB; this will guarantee that the subwoofer ac-
tivates itself at the right times when in “Auto On/
Standby” mode. You can then use the subwoofer's 
own  level  control  to  experiment  with  different 
bass levels that are suited to your various listen-
ing scenarios 

* Either of the  

specified crossover  

frequencies can be used. 

Try both to find out which 

sounds best to you.
