Congratulations on your fine new loudspeakers and thank you very much for choosing MAGNAT! You have made an excellent choice. The high-quality speakers produced by MAGNAT are renowned all over the world.

Please study the instructions and information below carefully before using your new loudspeakers.

The triangle with a lightning symbol warns the user that high voltage is used within the device which can result in electric shock.

The triangle with an exclamation mark informs the user that important operating and maintenance instructions (repair) are contained in the accompanying instruction manual, which must be observed.

Do not open! Risk of electric shock!

CAUTION: In order to avoid electric shock do not open the speaker housing/ mains adapters or remove the covers. The user is not to conduct any repairs him/herself. Repairs should only be conducted by qualified technicians! Do not use any sockets or extension cables that do not fully accommodate the plug of the device.

IMPORTANT SAFETY NOTICE

Please read through the instruction manual carefully before starting to use the device. This manual contains important information concerning operation and safety aspects. It is imperative you observe all of the information. Keep the manual in a safe location.

WARNING NOTICES: All of the warning symbols on the device, accessories and in the instruction manual itself must be adhered to.

• EXPOSURE TO HEAT: Only operate the device and accessories in a temperature range from 10^ to 40^ .

• The device should not be positioned near heat sources (heaters, ovens, radiant heaters, naked flames, etc.). When setting up close to an amplifier a minimum distance of 10 cm must be maintained.

• No naked flame sources, such as lighted candles, should be placed on the device.

• Pay attention to a sufficient ventilation of the device. The device may not be covered, e.g. by drapes, curtains. Maintain a distance of 20 cm to walls.

• EFFECT OF MOISTURE: The device should not be exposed to dripping or splash water. Neither should it be used to support vases or other containers filled with liquid. Do not expose the device to water or high levels of humidity. There is a danger of electric shock. In the event of contact with moisture or liquids remove the mains adapter immediately.

• FOREIGN MATERIAL: Ensure that no foreign material enters through the device openings and into the interior. This could trigger short circuits and even result in electric shock and fire.

• CLEANING: Please use a soft, dry cloth with no cleaning agents, sprays or chemical solvents, as these could damage the surfaces.

• ELECTRICAL CONNECTION: Please note the voltage levels on the information signs. The mains adapter for the device should only be operated with the voltage and frequency values specified on the signs.

• LIGHTNING PROTECTION/PREVENTIVE MEASURES: 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.

• MAINS CABLE: The mains cable must always be suitable for operation and it should only ever be laid out in a manner that prevents it from being trodden on. It should not be pinched by objects either, as this can damage the cable. When using plugs and power strips it must be ensured that the cable is not kinked at the point where it emerges from the socket. Do not connect or remove the mains cable with damp hands.

• The mains plug is used as the disconnecting device. Disconnecting devices shall remain readily operable.
• OVERLOAD: Sockets, power strips and extension cables should not be overloaded. If an overload occurs, there is a risk of electric shock and fire.
• SETTING UP: Please read the installation instructions.
• The device should only be positioned or mounted on a solid surface and not on moving base frames, otherwise there is a risk of injury.
• Only use attachments/accessories specified by the manufacturer.

DAMAGE THAT MUST BE RECTIFIED BY A SPECIALIST:

If any of the following damage occurs, disconnect the device from the mains immediately and contact a specialist to conduct the repair work:

• The device should not continue to be operated if there is visible damage to the mains cable. A damaged cable should not be repaired, but must be replaced.
• Damage to the mains socket at the device.
• If moisture or water has entered the device or foreign objects have fallen into the device.
• If the device has fallen and the housing is damaged.
• If the device does not work properly, even though all of the information in the instruction manual has been observed.

Only those subsequent alterations approved by the manufacturer may be conducted.

Only original spare parts should be used for repair.

After conducting any repairs the safety of device should be checked to ensure it is functioning correctly and safely.

Repairs must always be conducted by qualified specialists, as you might otherwise be exposed to dangerous high voltage levels or other hazards.

INSTRUCTIONS FOR DISPOSAL

In accordance with European Directive 2002/96/EC all electrical and electronic appliances must be disposed of separately via local collection points. Please observe the local regulations and do not dispose of your old appliances with normal household waste.

THE ACTIVE SUBWOOFER MAGNAT QUANTUM 7230A

This subwoofer has been adapted to provide the best visual and acoustic match to the MAGNAT QUANTUM 720 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 (8), mains-voltage switch (7)

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 230V 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!

Operating mode switch (6), operating state LED (5), power switch (10)

	Power switch ON Power switch OFF
Operating mode switch ON	Subwoofer is in permanent operation, the LED is green. Favourable setting for the reproduction of programmes with long quiet passages (this prevents the subwoofer from switching off unintentionally).	The subwoofer is switched off, LED is off. This is the setting for when subwoofer isn't used over long periods.
Operating mode AUTO	The automatic switching on/off is activated (recommended setting). The subwoofer switches on automatically when it receives 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 (2)

Connect your receiver's low-level subwoofer output (sub-pre-out) to the subwoofer's AV input (see Fig. 3). You will require a mono-cinch cable for this (not supplied).

High-level inputs (1)

For connection to the high-level (speaker) outputs of the receiver/amplifier, refer to Fig. 2.

Level control (3)

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.

Cross-over frequency control (4)

Used to set the upper limit of the subwoofer operating range. The cross-over frequency should be set to 100 to 150Hz when the system is used in combination with shelf loudspeakers or 50 to 100Hz when used with stand loudspeakers.

Phase switch (11)

In normal use the phase switch should be set to 0^ . However, in rare cases it may be advantageous to set the phase to 180^ (e.g. if the subwoofer is far away from the front loudspeakers or in the event of unfavourable acoustics in the room). Generally speaking: the setting where the lower base tone area has a fuller sound is the correct one.

Fuse (9)

Only use a fuse with the parameters indicated inside the triangle next to the fuse holder, on the rear of the amplifier.
