2.1 Important Information for set up
After having unpacked your loudspeaker, please allow the system to acclimate to
the temperature of the room for approximately an hour.
We recommend using high quality cables to guarantee optimal performance.
It is important to ensure the speakers sit firmly on a solid surface!
We recommend that you retain the original packaging, as it is the best way to
guarantee safe transportation should the need to do so arise.
Please note that the loudspeakers will take some break-in time to achieve
optimum sonic performance.
2.2 Connecting the speakers
a) Before connecting the loudspeakers to your audio components and the power
source make sure that both the loudspeakers and your audio source are switched
off and set the level controls fully counterclockwise.
b) Connect the loudspeakers with your audio source by using XLR cables. The male
plug goes into the loudspeaker, the female plug into your audio component.
c) Check if the specified voltage matches the voltage of the power supply you use.
If this is not the case do not connect the loudspeakers to a power source! Please
contact your local dealer or national distributor.
If the voltages match, use the included power cables to connect the loudspeaker
to the AC sockets.
d) Switch on the main on/off switches on the back panel of the loudspeakers.
e) Make sure that the line out level (volume) of your stereo is either at a low level or
all the way off. Then, switch on your audio system.
f) Turn on your source of music and adjust the volume carefully.
2. Quick Start

Classic Center MK3 (Active Version) Manual / English
The proper positioning of your loudspeakers is of extreme importance to the sound
quality. We would therefore like to give you some advice concerning room acoustics
and the setting up of your loudspeakers. Since every room is unique, we can only offer
general recommendations.
3.1 Room acoustics
Room acoustics come down to essentially three aspects:
a) Reverberation: The ‘sound’ of a room is to some extend a result of its reverbera-
tion, i.e. to how the sound waves are reflected. Soft furniture (like carpets, cur-
tains, or sofas) tends to absorb sound waves, especially higher frequencies. Hard
materials like stone or glass reflect sound waves almost entirely. In general, rever-
berant rooms are rather unforgiving in terms of authentic music reproduction due
to the great number of reflections.
b) The room dimensions: The volume of a room is the second important aspect of its
acoustics. The same loudspeaker will sound different in different sized rooms with
similar sonic characteristics. Therefore, the size of your room partly determines
the positioning of your loudspeakers.
c) The listening distance: The distance between the listener and the sound source
is the third crucial aspect in loudspeaker positioning. If this distance is either too
great or too small, the sound will be compromised.
3.2 General recommendations
Please make sure that there are no obstacles in the way from the monitor to your
ears. You should be able to see the speakers completely.
The distance to the surrounding walls should be at least 40 cm to avoid early
reflections, which will degrade the sound.
The loudspeakers should be aligned with the listener’s position.
Please note that vibrating parts of nearby objects can mask the sound.
3. Speaker Placement

3.3 Tweeter at the height of ears
The Tweeter should be positioned approximately at the
height of your ears. If the speaker does not point right
in your direction, you might lose sound
information.
In case you need to position the speaker in a significant
lower or higher position, the monitor should be angled
accordingly.
3.4 The Stereo Triangle
If the loudspeaker is going to be used for stereo ap-
plications, the optimum listening position should be at
the top of an imaginary equilateral triangle with the two
loudspeakers should be placed at the other two points
of this triangle.
The loudspeakers should be aligned with the listener’s
position.
3.5 Surround Placement
Speaker positioning for multi-channel stereo purposes
is ideally based on a circle with speakers placed at 0°
(Center), 30° (Front Right), 110° (Rear Right), 250°
(Rear Left), 330° (Front Left), with the listener being
the circle’s center (Radius between 0.7-2.0 m). This ITU
recommended configuration may vary depending on the
purpose of the control room (music or film). However,
it is recommended to create a symmetrical listening
position with the front side and surround speaker
pointing to the listener’s ear.
The distance to the surrounding walls should be at least
40 cm to avoid early reflections, which can degrade the
sound.

4.1 LED
On the bottom of the tweeter you find an
LED. It indicates Power on and, in case of
an overload, the function of the protective
circuit.
Please note: When the speaker is switched
on, the LED will flash red a few times. This
does not indicate an overload.
• The LED starts to glow green during normal operation (the power switch is
located on the rear side of the speaker).
• In case of an overload, the OL LED will flash red. The protective circuit will safe
your speaker from damage.
4.2 Controls
On the rear side you will find controls that
allow detailed fine-tuning of your loudspeakers
to your particular room acoustics and per-
sonal listening preferences. The following tips
are intended to assist you at using the
controls in the best manner.
Please note that using the controls may
have a great impact on the overall sound
characteristics of your loudspeakers. We
recommend using the controls with utmost
care and only after several audio tests with
familiar recordings.
4.3 Mode
This button allows you to choose between
• Signal On: woofer starts operation as soon as a
musical signal arrives, and stops after 15 minutes without a signal.
• Continuous: the unit is permanently working.
We recommend the ”Signal on” position. It minimises power
consumption and makes handling very easy.

4.4 Input Gain
‘Input Gain’ regulates the overall input sensitivity of
your loudspeaker within a range of -10 to +10 dB, and
controls the volume of your loudspeaker equally in all
frequency ranges.
4.5 High Gain
Whereas the ‘Input Gain’ raises or lowers the overall in-
put sensitivity up to +/-10 dB, the ‘Tweeter Gain’ works
within the frequency range of the tweeter only, raising
or lowering up to +/-4 dB.
This is a considerable change of the sound characteris-
tic and should be used with caution. However, to meet
difficult room acoustics or adapt to a special taste the
Tweeter Gain will serve you well.
4.6 High / Low Shelf EQs (Room EQs)
The other two controls operate in a different manner.
The ‘High Shelf’ and the ‘Low Shelf’ are shelving filters,
which progressively raise or lower up to ±6 dB.
Whereas the gains raise or lower a specific frequency
range as a whole, the shelving filters do not alter a whole
frequency band but alter in this band: from a certain point
(6 kHz respectively 150 Hz in this case) the frequencies
are gradually being changed (see fig.).
4. Speaker Adjustment
Room EQ <150 Hz for low frequencies
below 150 Hz
Room EQ >6 kHz for high frequencies
above 6 kHz
