Adjustable AV receiver
Most AV receivers feature a menu with speaker settings (re-
ferred to as “Speaker Setup” or similar). In this case, you should
make the following settings:
• “Subwoofer” to “on”
• Crossover frequency for subwoofer to 80 Hz
• Subwoofer volume to more than 75 %
Set the subwoofer volume to the THX level. For this, push the
button
17
“THX” on the remote control while the subwoofer is
on. The display
12
“THX” illuminates in red.
These settings ensure that the subwoofer is used optimally and
you can do the final fine tuning via the automatic calibration
function or the menu of your AV receiver.
Non-adjustable AV receiver
If your AV receiver does not provide the above options, you can
make the most important settings directly on the subwoofer.
To do so, you will need a CD or DVD with adequate, powerful
sound.
Note
The setting elements on the back side of the sub-
woofer only work when THX mode is turned off (the
display
12
“THX” is off).
• Set the separation frequency with the control
4
“LP FILTER”
to approx. 80 Hz (second dash). This way, you specify that
the subwoofer only plays sounds up to this frequency (adjust-
ment range: 60–220 Hz).
• With the control
3
“HP FILTER” you can block low frequencies
(adjustment range: 20–60 Hz).
• With the switch
5
“SENSITIVITY”, soft signal sources can be
amplified by 10 dB (switch setting: left).
• Once you have set the best sound, switch phase shifting
on and off several times with the button
15
“Phase” (display
11
“Phase” is green). Then select the setting at which the
subwoofer sounds as loud and precise as possible.
• Optimise the settings with other CDs/DVDs and different
volumes.
Ideally, you will hear the system with a volume of 80–85 dB
SPL. As a result, quiet passages will still be audible and loud
passages will not be detrimental to hearing. At best, you should
use a sound lever meter for determining the volume, which you
can purchase in our webshop.
