Thank you very much . . .

. . . for choosing one of our Speaker Systems. This manual is valid for model LS-180 in

several colour combinations. For your own safety and in order to learn all about the

functions available, please read this manual and keep it for future reference. And if you once

sell the unit please include the manual.

Important Safety Instructions, please Read Carefully!

•

When using an amplifier with a rated output power higher than the nominal input power

of the speakers, be very careful. Never exceed the maximum input of the speaker

system, otherwise the speakers will be destroyed.

•

Even if the output of the connected amplifier is lower than the load capacity of the

loudspeaker, an amplifier may not be operated at maximum volume, because that would

increase the risk of “clipping”, i.e. that there can be direct-current voltage at the

output of the amplifier if even only briefly. Direct-current voltage destroys the voice coils

of the loudspeakers.

•

Any time you notice distortion or abnormal sound, immediately reduce the volume

control on your amplifier to a lower setting.

•

Never attempt to open the housings of your speaker boxes or to service the product

beyond that described in this manual. All servicing or repair must be referred to qualified

service personnel authorised by us.

•

So that neither the wood nor the loudspeaker membranes can be damaged, this

appliance must never be operated in damp rooms (e.g. bathroom). The loudspeakers

must also only be operated within closed rooms.

•

Never let children play with the boxes or stick anything into it.

•

Do not leave the boxes in direct sunlight for a long time, otherwise discoloration may

result. Avoid positions with heavy dust or poor ventilation. The unit should not be

exposed to mechanical vibrations or shock.

•

You can use a soft damp cloth to clean the housings. Don’t use strong cleansing

products. NEVER touch the membrane of the speakers.

•

Lay the loudspeaker cable so that nobody can stumble over it.

Positioning the Speakers

You can mount the speakers on a plane and stable surface.

The spacing between your loudspeakers will depend on the size of your listening room

and the distance of your seating from the loudspeakers. As a general rule, they should

not be closer than 1.5m (5 ft) and the space between them should not exceed the distan

ce of your listening position. Placement of the two loudspeakers and the listener on the

points of an equilateral triangle is not a bad rule to follow.

The best balance of sound is achieved when the listener is within +5° of the reference

axis in the vertical plane. This equates to a range in height of 0.5m (20 inches) at a typi

cal listening distance of 3m (10 ft). At progressively larger angles, the change in the rela

tive time delay between the drive unit will gradually cause a response dip around the mid

to high crossover frequency.

The loudspeakers of the boxes should be at the same height as the ears of the listener.

Take care not to set up the speakers close to a TV set as otherwise this can lead to slight

colour distortions of the TV picture. If that should happen increase the distance between

the speakers and the TV set. Then switch off the television and wait for 10 minutes before

you turn it on again.

Connecting the Loudspeakers to the Amplifiers

In order to avoid damage of the speakers or other connected devices, please establish all

connections while the amplifier is switched off.

Inphase connection

For optimum sound quality it is inevitable to connect speakers and amplifier inphase. I. e.,

within the respective channel (right or left)

- the „+ terminal” of the amplifier must be connected to the „+ terminal” of the box, and

- the „— terminal” of the amplifier must be connect to the „— terminal” of the box.

If the speakers are out of phase (i.e. the + terminal of one amplifier channel is connected to

the – terminal of one speaker, and the – terminal of one amplifier channel is connected to

the + terminal of one speaker), the sound will be affected and the speakers may be

damaged.

If the phase is reversed, the stereo image will be unstable, and the bass components will not

be clearly reproduced. Correctly connected (“in-phase”) speakers will give you a stable,

well-defined stereo output, with a clear, powerful bass sound. Make sure that each +

terminal of the amplifier is correctly connected to the + terminals of the appropriate

speaker. Most speaker cables have one ridged or striped part, to help you distinguish + and

-. If you need to reverse the connections of one speaker to correct the phase, make sure the

amplifier is turned off before you disconnect the speaker.

Make sure that the box that you want to set up to the right of the listening position is

connected to the right channel on the amplifier, and the left box to the left channel.

Establish connection

Remove 2cm of insulation from the loudspeaker cable. To connect the cable, twist the flex.

Then open the loudspeaker clamp , stick the bared end of the cable - not insulated parts of

the cable - into the opening, and close the clamp.

Please carefully read the instruction manual of the respective amplifier to learn more about

the speaker connection.

You have paid attention to quality in your purchasing of loudspeakers and you should also

do this when choosing the loudspeaker cable. The cross-section and conductor material

play a decisive role in the later musical pleasure.

When the operating life of this device has ended it must not be

disposed as domestic waste, but in accordance with national
