• When operating your subwoofer, on no account ever lay it with the panel containing the switches,

controls and input/output sockets facing down as this could cause the unit to overheat; please ensure

a minimum distance of 5cm around the apparatus for sufficent ventilation. The woofer, the bass

reflex opening and possible existing ventilation openings should never be covered with items such as

newspapers, table-cloths, curtains, etc.

• On no account ever insert a hand, arm or any object into a loudspeaker’s sound outlets (e.g. bass

reflex pipe) as this could cause injury or material damage. At particular risk in this respect

are children and pets.

• Allow no-one but appropriately qualified service engineers to carry out technical maintenance and

repair work on your active loudspeaker. This will be necessary in the event of any form of damage,

i.e. damaged mains cables and plugs, or when some object has fallen onto the speaker cabinet or

if the unit itself has fallen over or been dropped, or if it has been penetrated by any type of liquid.

Never open up the device yourself since any physical contact whatsoever with the mains voltage

(230V/115V) can have fatal consequences.

• Never use active loudspeakers as seating or climb up on them (instead of using a ladder)!

• Your loudspeaker units have been designed for long years of home use and should not therefore be

used for professional purposes.

• For the purposes of mounting and placement of these products, please only use furniture and other

devices that are obtainable from the manufacturer and marketed for or together with the product in

question. Take extreme care when moving any table devices or shelves upon which the products are

placed as the units could otherwise tip or fall over and cause damage or injury.

• Avoid placing your loudspeakers anywhere with high levels of humidity or dampness. Permanent

relative humidity or exposure to direct sunlight (UV radiation) can cause warping of wooden speaker

cabinets or lead to their premature aging and thus affect the unit's performance. Besides, do not

position the subwoofer directly adjacent to sources of heat, e.g. radiators. Moreover, do not place

naked flame sources, such as lighted candles on the speaker cabinet.

• Our fitting accessories should only be used to install products that we have specifically designed for

wall mounting. Take special care to ensure that all components are securely screwed into place! We

also recommend using additional safeguards, for example chains, etc. to ensure secure and safe

mounting.

• Loudspeakers in operation for long periods at excessively high volume levels are not only a source

of disturbance for neighbours but can also have serious health-related consequences for the user as

well!

• Loudspeakers without magnetic shielding can cause discoloration or distortion of the TV picture. To

avoid this, place non-shielded loudspeakers at least 50 cm clear of the TV set. Please avoid deposit-

ing, for example, credit cards, diskettes, audio or video cassettes or any other form of magnetic data

carriers on the speaker cabinet as this could otherwise lead to loss of data stored on such objects.

Likewise, do not place and operate magnetic tape devices in the direct vicinity of such loudspeak-

ers.

• Please do not throw the packaging away as you might possibly need it for transportation of the loud-

speaker system at a later date. Keep the polythene bags out of the reach of children since

they can cause asphyxiation if used for any other than their intended purpose.

Setting up

Besides the unit’s actual settings, a subwoofer’s bass reproduction essentially depends on

where the unit is positioned in the listening room. Proximity to walls or even placement in

a corner makes the bass sound come over louder – but also less well defined and accurate

– than if in a more free-standing position. Since the acoustic characteristics differ from room

to room, we recommend finding the optimum compromise between bass volume and preci-

sion by simple trial and error. It won’t matter if you set up the subwoofer nearer to the left

hand satellite than the right hand one – or vice versa – since the low bass sounds are not

localizable.

If your subwoofer directs its sound downwards, you must fit the supplied loudspeaker foot,

which can be designed as „spikes“ as well (depending on the model), before you start to use

the system.

Operating modes

Units with a POWER switch for mains and a POWER switch for stand-by:

If the mains POWER switch is in OFF position, the unit is turned off completely. If the mains

POWER switch is in ON position, the switch for stand-by operates as follows:

ON: The unit is permanently on.

STAND BY: The unit switches on automatically, if a music signal is received and auto-

matically switches to stand-by mode after approximately 15 minutes, if no

music signal is received.

OFF: The functions are switched off. The amplifier will be kept at temperature to

continue operation soon.

Units with POWER switch for mains and AUTO switch for stand-by:

If the mains POWER switch is in OFF position, the unit is turned off completely. If the mains

POWER switch is in ON position, the switch for stand-by operates as follows:
