Activating and deactivating

supply on or off. When the subwoofer is activated, the
power LED 12 "Power" is green. If the subwoofer is in
standby, it is red.

Automatic activation/deactivation

13
11
Use switch 9 "ON/AUTO" to change the operating
condition:
ON The subwoofer is permanently switched on.
AUTO
The subwoofer switches itself on as soon as a
signal is present at input 13. If there is no audio signal for
20 minutes then the subwoofer switches to standby.
If the automatic power switching is not functioning cor-
rectly you can use control 11 to increase (turn to the right)
or decrease (turn to the left) its sensitivity. You will need a
small screwdriver to do this.
Adjusting the AV receiver and
subwoofer
Most AV receivers have a menu with settings for the
speakers (called "Speaker Setup" or similar).

When using this speaker set

• Switch 9 "ON/AUTO" to "AUTO".
• Switch 8 "MODE" to "THX".
• Volume control 1 "VOLUME" to the middle setting
("THX").
With these settings the subwoofer use is ideal and it will
behave according to THX specifications. You can carry
out the final fine tuning later on your AV receiver.

• Set the switch 8 "MODE" to "USER". This activates
controls 2 "HIGH-PASS" and 3 "LOW-PASS".
• Set the crossover frequency to approx. 80 Hz with con-
trol 3 "LOW-PASS". This determines that the subwoofer
only emits sounds up to this frequency.
• Set control 2 "HIGH-PASS" to "20 Hz". This deter-
mines that the subwoofer only emits sounds above this
frequency.
• Set the volume control 1 "VOLUME" to the middle set-
ting.
• Now carry out a sound check and adjust the volume
control 1 "VOLUME" until the subwoofer is "easily
heard" and control 3 "LOW-PASS" until the low tones
sound strong but do not buzz.
If any deep "hits" are too hard increase the setting on
control 2 "HIGH-PASS".
• Once you have found the best sound in this way adjust
the switch 7 "PHASE" in both directions a number of
times. If you notice a considerable improvement in
sound quality, refine the settings until optimal. Other-
wise leave the switch set to "0°".
• Repeat these steps with different CDs and DVDs.
