Adjusting amplifier/AV receiver and
Subwoofer
Most amplifi ers/AV receivers feature a menu with speaker set-
tings (referred to as “Speaker Setup” or similar).
Amplifi er/AV receiver setup
• Subwoofer to “on”
• Crossover frequency for subwoofer:
– 100 Hz, if satellites with 130 mm midrange speakers are
connected.
– 80 Hz, if satellites with 160 mm midrange speakers are
connected.
• Volume of the subwoofer to more than 75 %
Subwoofer setup
• Switch 6 “Off • Auto • On“ to “Auto“.
• Switch 8 “Low Pass • Full
Range“ to
“
Full Range“
(switch set-
ting: right)
.
• Control 3
“Volume“ to center position.
• Control 5 “Frequency“ to the right until it stops.
With these settings, the subwoofer will work optimally and
the automatic activation/deactivation is functioning properly.
You can make the fi nal fi ne tuning later on your amplifi er/AV
receiver.
Subwoofer setup with non-adjustable amplifi er/
AV receiver
If your amplifi er/AV receiver does not provide the above op-
tions, 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.
• Set switch 8 “Low Pass • Full Range” to the left to “Low
Pass”. This activates the controlrs 5 “Frequency” and 7
“Phase”.
• Set the crossover frequency with the controller 5 “Frequen-
cy” to about 100 Hz (fourth mark). This sets the subwoofer to
reproduce only frequencies up to 100 Hz.
• Set the control 7 “Phase“ to “0°“.
• Set the control 3
“Volume“ to center position.
• Now make an audition and then adjust the volume control
3 “Volume” until the subwoofer is clearly audible and adjust
the control 5 “Frequency” until the bass is strong but not
booming.
• Once you have set the best sound, move the control 7
“Phase” several times until it stops in both directions. If you
notice a marked improvement in sound here, fi nd the optimal
setting. Otherwise, leave the knob to “0°”
• Optimise the settings with other CDs/DVDs and different
volumes.
Automatic activation/deactivation
With switch 6 “Off•Auto•On” you can switch the operating
state:
Off Standby
Auto The subwoofer activates as soon as an audio signal is
present on the input jack 1 “Line In”. If there is no audio
signal for some period of time, the subwoofer switches
to standby.
On: The subwoofer is continually activated.
