• Do not use any cleaning agents or chemical solvents when cleaning, as these could damage the
surface of the device.
• Repairs must always be conducted by qualified specialists, as you might otherwise be exposed
to dangerous high voltage levels or other hazards.
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 (11), mains-voltage switch (8)

V for operation in Europe.
Warning: Connecting the subwoofer to a 230 V mains outlet while the voltage selector is set to 120 V will lead to
immediate destruction of the amplifier!
