THE ACTIVE SUBWOOFER
Figure 3 shows the subwoofer's controls:
Mains connection (1)
The subwoofer is equipped with an integrated amplifier and needs to be connected to a mains outlet by
means of the supplied mains cable.
Operating mode switch (3), operating state LED (4), power switch (2)
Power switch ON
Operating mode Subwoofer is in permanent operation, the LED is green.
switch ON Favourable setting for the reproduction of programmes
with long quiet passages (this prevents the subwoofer
from switching off unintentionally).
Operating The automatic switching on/off is activated (recom-
mode AUTO mended setting).
The subwoofer switches on automatically when it re-
ceives a signal from the receiver, the LED turns green.
It automatically switches to standby after receiving no
signals for some minutes, the LED turns red.
AV input (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).
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.
SUB/LFE switch (7)
When the switch is set to the SUB position the crossover frequency of the subwoofer is set to approx.
100Hz. This frequency is optimally co-ordinated to the satellite and centre speakers of the home cinema
set.
When connected to a modern AV receiver the switch should be set to LFE (this deactivates the filter in
the subwoofer). The crossover frequency between the subwoofer and satellite/centre speakers must now
be adjusted via the receiver's menu. These values depend on the acoustics of the room and the setup
of the speakers and should be between 100Hz and 150Hz.
Fuse (8)
Only use a fuse with the parameters indicated inside the triangle next to the fuse holder, on the rear of
the amplifier.
