AV input "LFE" (6)
Connect your receiver's low-level subwoofer output (sub-pre-out) to the subwoofer's AV input (see Fig.
2). You will require a mono-cinch cable for this (not supplied). Note: Warning: when the subwoofer is
controlled through the LFE input, the cross-over frequency control is not functional.
Line inputs (6 / 7)
Please refer to fig. 3 for connecting to low-level outputs on a receiver/amplifier (stereo mode). The two
channels are added to each other and are output by the subwoofer.
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 40 to 120 Hz when the system is used in combination with shelf loudspeakers or 50 to 100 Hz when
used with stand loudspeakers.
Phase regulator (3)
In normal use the phase control should be set to 0°. However, in rare cases it may be advantageous to
vary the phase to between 0 and 180° (e.g. if the subwoofer is far away from the front satellites or in the
event of unfavourable acoustics in the room). Generally speaking: the setting where the lower base tone
area has a more natural 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.
