Adjusting
Adjustable AV receiver
Most AV receivers feature a menu with speaker settings
(referred to as “Speaker Setup” or similar). In this case,
the following settings should be made:
• Size of the front, center and rear speakers to “normal”
or “small” – not “large”
• “Subwoofer” to “on”
• Crossover frequency for subwoofer to 80 Hz
• Volume of the subwoofer 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 sub-
woofer is on. The display
12
“THX” illuminates in red.
These settings will ensure that the speakers are used
optimally and you can make the fi nal fi ne 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
subwoofer only work when THX mode is turned
off (the display
12
“THX” then turns green).
• 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 (adjustment 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 amplifi ed by 10 dB (switch setting: left).
• Once you have set the best sound, switch phase shift-
ing 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 differ-
ent 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. We
recommend you use a sound lever meter for determining
the volume, which you can purchase in our webshop.
