AV input (2)
Connect your receiver‘s low-level subwoofer output (sub-pre-out) to the subwoofer‘s AV input (see Fig.
3). You will require a mono-cinch cable for this (not supplied).
High-level inputs (1)
For connection to the high-level (speaker) outputs of the receiver/amplifier, refer to Fig. 2.
Level control (3)
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
100 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 (11)
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.
Fuse (9)
Only use a fuse with the parameters indicated inside the triangle next to the fuse holder, on the rear
of the amplifier.
