Level control (5)
This control is used to set the bass volume according to your preferences. Proceed as follows::
1. Set the bass control of your amplifier into its centre (linear) position.
2. Important: Set the level control to its left stop (lowest volume).
3. Now, play back some music and set the volume control of the amplifier to the desired level.
4. Set the subwoofer level control to the desired bass level.
Cross-over frequency control (4)
Used to set the upper limit of the subwoofer operating range. The cross-over frequency should be set
to 50 to 150 Hz when the system is used in combination with shelf loudspeakers or 50 to 100 Hz
when used with stand loudspeakers.
Phase switch (1)
In normal use the phase switch should be set to 0°. However, in rare cases it may be advantageous
to set the phase to 180° (e.g. if the subwoofer is far away from the front loudspeakers or in the event
of unfavourable acoustics in the room). Generally speaking: the setting where the lower base tone
area has a fuller sound is the correct one.
MAINTENANCE
The surface is best cleaned with a mild household cleaner. On no account use furniture polish or
similar products.
