Congratulations on your fine new loudspeakers and thank you very much for choosing MA. 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 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 impera you observe all of the information. Keep the manual in a safe location.

• Never subject the subwoofer to dripping or splashing water. Do not place any flower vases or other filled recipients on top of the subwoofer.
• The distance between the active subwoofer enclosure and the walls of the room or other objects (e. g. furniture, shelf units) may not be less than 5 cm on any side.

The aluminium plate and cooling fins of the amplifier at the rear of the active subwoofer serve to cool the built-in amplifier; for this reason, they must also be at least 5 cm away from all objects and must not be covered (e.g. by a curtain).

The bass reflex opening(s) on the active subwoofer must not be covered (e.g. by curtains, etc.) in order to guarantee adequate ventilation of the amplifier.

• The subwoofer should not be positioned near heat sources (heaters, ovens, radiant heaters, naked flames, etc.).
• Only operate the subwoofer at an ambient/room temperature from 10°C to 40°C. The active subwoofer may not be used in very humid rooms.
• Please do not place any items with naked flames (e.g. candles) on the active subwoofer.
• Please do not touch or connect the mains cable when your hands are damp.
• Keep the mains cable away from heaters.
• 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.
• Never place heavy items on the mains cable.
• The mains cable should always be freely accessible.

• 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 MAGNAT OMEGA SUB 250 A LTD ACTIVE SUBWOOFER

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 to items and walls is at least 30 centimetres and at least 20 centimetres from the rear as otherwise bass reproduction may be impaired.

THE SUBWOOFERS' OPERATING ELEMENTS (FIG. 1)

Mains connection (11), mains-voltage switch (13)

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 fitted amplifier!

Mains switch (10), power LED (1), power switch (2)

	Mains switch ON	Mains switch OFF
Power switch ON	Subwoofer is in permanent operation, the power LED is green.Favourable setting for the reproduction of programmes with long quiet passages (this prevents the subwoofer from switching off unintentionally).	Subwoofer switched off, Power LED off.This is the setting for when subwoofer isn't used over long periods.
Power switch AUTO	Subwoofer initially in standby mode, the power LED is red.The subwoofer switches on automatically when it receives a signal from the re-ceiver, the power LED turns green.It automatically switches to standby after receiving no signals for around 15 min-utes, the power LED returns to red.Recommended setting.

Line inputs (7/8)

Please refer to Fig. 2 for connecting to low-level outputs on a receiver/amplifier (stereo mode). The two channels are added to each other and are output by the subwoofer.

Please refer to Fig. 3 for connecting to an AV receiver with low-level subwoofer output. A second subwoofer may be connected to the second input socket (8).

High-level inputs (9)

Please refer to Fig. 4 for connecting to the receiver's/amplifier's high-level (loudspeaker) outputs. The two channels are added to each other and are output by the subwoofer.

Phase regulator (3)

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

Level control (6)

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.

Warning: when connecting to an AV receiver's subwoofer output, the subwoofer level should be set to 0 dB in the receiver's set-up.

Crossover frequency control (5), SUB/LFE switch (4)

1. Switch SUB/LFE switch to 'SUB': this option is selected when a normal (broadband) audio signal is available as the input signal (e.g. stereo mode). The crossover frequency control is used to set the subwoofer's maximum working frequency. The frequency should be set to 100 Hz – 150 Hz for shelf speakers. The setting should be 50 Hz – 100 Hz for floor speakers.
2. Switch SUB/LFE switch to 'LFE': this option is selected when a low-pass filtered signal (LFE signal) is available (e.g. connecting to the subwoofer output on an AV receiver). The internal filter will be switched off, the crossover frequency control will have no effect. Here, the crossover frequency between the subwoofer and surround loudspeakers must be set on the AV receiver. Please also refer to the AV receiver's operating instructions.

Fuse (12)

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