POSITIONING
The frequency range reproduced by the subwoofer cannot be pinpointed by the human ear. That's
why positioning generally doesn't present any problems. However, it is preferable to place the speaker
close to the front loudspeaker in front of the listening position. You should also make sure that the
distance from the sides and from the rear to items and walls is at least 20 centimetres as otherwise bass
reproduction may be impaired.
THE SUBWOOFER'S OPERATING ELEMENTS (FIG. 1)
Mains connection (1), mains-voltage switch (3)
The subwoofer is equipped with an integrated amplifier and needs to be connected to a mains outlet
by means of the supplied mains cable. The voltage selector has been set at the factory to 230 V for
operation in Europe.
Warning: Connecting the subwoofer to a 230 V mains outlet while the voltage selector is set to
115 V will lead to immediate destruction of the amplifier!
