• The mains plug is used as the disconnecting device. Disconnecting devices shall remain readily operable.
• If the device is not going to be used for a prolonged period (e.g. when on holiday), it should be
disconnected from the mains by removing the plug. The device should also be disconnected from
the mains in the event of a thunderstorm. Doing this will prevent damage caused by lightning and
overvoltage.
• 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.
THE ACTIVE SUBWOOFER MAGNAT SIGNATURE SUB730A
This subwoofer has been adapted to provide the best visual and acoustic match to the MAGNAT
Signature range of loudspeakers. However, it goes without saying that it may be combined with other
loudspeakers. When connecting your loudspeaker, please make sure that everything has been switched
off. Furthermore, make sure that all loudspeaker cables are connected to the proper poles, i.e. the positive
pole for the output is connected to the positive pole for the input and the negative pole with the negative
pole. Please also refer to your receiver's/amplifier's and loudspeakers' instructions.
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 (10), mains-voltage switch (9)
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!
