As the colours of the wires in the mains lead
of this appliance may not correspond with the
coloured markings identifying the terminals in
your plug, proceed as follows:
1 . The wire which is coloured blue must be
.
connected to the terminal which is marked
with the letter N or coloured black .

3 Applications
This compact active subwoofer is used as a
low-frequency complement of existing audio
systems for hi-fi applications, home cinema and
home recording applications . It is equipped with
a 25 cm (10") bass speaker . Its amplifier offers a
peak output power of 200 W .
The subwoofer features an adjustable low
pass filter, a volume control, a phase reversal
switch and an automatic standby mode . The
integrated amplifier is provided with protective
circuits to prevent overload and overheating .
Inputs are provided for connection to stereo
outputs with line level and for connection to
speaker outputs (with feed-through facility for
the other speakers) .
The subwoofer also features an LFE input . In
multi-channel systems for cinema applications,
e . g . "5 .1", the LFE channel ("Low Frequency
Effect" or "Low Frequency Enhancement") is
used for low-frequency special effects .
4 Setting Up and Connecting
Set up the subwoofer on a flat surface . It is
not important to place the subwoofer exactly
in the middle between the stereo speakers as it
will not be possible to precisely locate the very
low frequencies reproduced by the subwoofer .
However, do not place it too close to walls or
in corners; this would distort the frequency re-
sponse and prevent the heat dissipation of the
integrated amplifier . Likewise, do not cover the
bass-reflex openings on the lower side .
Prior to making connections or changing
any existing connections, switch off the sub-
woofer and the units to be connected .
