2.2. Positioning the Speakers
NOTE:
The following instructions are intended as guidelines to help you position the speakers
in a suitable way.
2.2.1 Acoustic alignment of the speakers
LANSCHE No.3.2 speakers should be placed at least 20 cm from the back wall, with a slight
inward angle of 5° to 8° to make sure they are not positioned parallel to the wall behind
them. Due to reasons of sound propagation, placing the speakers close to the wall will
adversely affect the sound quality. The walls reflect the sound, which is perceived by the
listener slightly later than the direct sound emission, thus distorting the main sound signal.
The best way to position your new speakers is to set up a so-called “stereo triangle”. This is
accomplished by arranging the speakers such that they create an equilateral triangle, with
the listener in the third position (equal distance between all points).
2.2.2. Distance between the speakers
The distance between the speakers for a stereo setup depends on the given distance from
the listening position. The distance between the two speakers should be slightly less than the
distance to the listening position. Thus, the closer you are to the speakers, the closer the
speakers should be to each other.
For optimal positioning, start with a basic distance of two meters, which is then adapted
according to the actual room dimensions.

When connecting speaker cables, it is absolutely necessary to check for proper polarity: plus
to plus and minus to minus. The screw clamps on the loudspeakers as well as the connectors
on the amplifier are colour coded and labelled (positive pole = red, negative pole = black).
To ensure proper connections, the wires on most speaker cables are also differentiated by
colour, form, or marking. Reversing the polarity of the right and left channels results in sound
distortions.
In order to avoid short circuiting, the bare ends of the stripped speaker cables should be as
short as possible, should not protrude from the screw clamps, and should never be allowed
to touch each other. If in doubt, please also refer to the operating instructions of your
amplifier.
NOTE:
The choice of speaker cables has a major impact on the sound of the
system and should therefore be considered carefully. The No.3.2 was
developed using high-quality connection cables and should also be
operated in your home with the appropriate cables. Please consult with your
LANSCHE AUDIO dealer to determine which cables are best for your system
in order to maximize the sound quality of your No.3.2.
2.3.2. Connecting the amplifier (bi-amping / bi-wiring)
To use bi-wiring or bi-amping first remove any cable bridges from the terminals
(4,5,7,8) located on the rear panel. Connect your speaker cables as shown in the
drawing on the next page.
For bi-amping use either: 4 mono amplifiers, 2 stereo amplifiers or one 4 channel
amplifier.
NOTE:
The choice of speaker cables has a major impact on the sound of the
system and should therefore be considered carefully. The No.3.2 was
developed using high-quality connection cables and should also be
operated in your home with the appropriate cables. Please consult with your
LANSCHE AUDIO dealer to determine which cables are best for your system
in order to maximize the sound quality of your No.3.2.
2.4. Operating the Speakers

LANSCHE AUDIO OPERATING INSTRUCTIONS No.3.2
Page 9 / 17
Switch on the speaker system No.3.2 by activating the power switch (2) located near the top on the
rear of the speaker cabinet. The indicator light on the power switch (2) and the logo (6) at the front
of the speaker will illuminate light blue.
The CORONA plasma tweeter starts up automatically after about 45 seconds with a visible plasma
ball. This starting process may be accompanied by a clearly audible hiss. After about 45 more
seconds the plasma tweeter automatically switches over from the start-up process to normal
operating mode. This will be accompanied by a visible reduction in the size of its plasma ball.
3. CORONA Plasma Tweeters
3.1. Information about CORONA Plasma Tweeters
a. The CORONA plasma tweeter emits a bright light (plasma ball) during the start up operation.
As with any bright light source avoid looking directly at it from a short distance (less than 30 cm).
b. Avoid allowing any objects to enter into the CORONA’s plasma ball chamber (except for cleaning
purpose, see section 3.5 of this manual). This could damage the chamber.
When in operation, there is no danger of a hazardous electric shock if a metallic object should
accidentally find its way into the chamber (inserted by a child, for example).
c. During operation, the temperature at the electrode tip is about 600 °C (1,472 °F). Do not allow any
kind of material (especially flammable materials) to enter the chamber. Even after switching off,
the temperature remains high for at least 30 minutes.
d. During operation, the horn of the CORONA can heat up to 55 °C (130 °F). Depending on the
ambient temperature this can be higher.
e. CORONA plasma tweeters are highly sensitive electronic devices. Please protect them from
mechanical impacts or other mechanical influences.
f. Particularly during the initial start up phase of operation, it is possible the CORONA will produce
some noise. This is due to dust and other stray particles which found their way into its chamber and
are being removed.
g. Never allow air to be blown directly and continuously in to the CORONA’s plasma ball chamber.
This will produce audible noise and possibly ozone.
h. Due to the nature of the vacuum tube in the CORONA it is possible it fails to self-start after being
powered off for a few minutes. This phenomenon is due to the ‘memory effect’ of the vacuum
tube. Please wait a while and try again.
i. The self-starting of the CORONA is dependent on the cleanliness of the electrode. If the electrode
has not been cleaned recently then a layer of dust and foreign particles will have formed over
it. Cleaning will be necessary, see section 3.5 in this manual. .
j. The colour and brightness of the CORONA’s plasma ball is dependent on dust and foreign deposits
on the electrode, the operating temperature, the air humidity and the electrode’s running hours.
When the CORONA is in the start up phase its plasma ball can become very bright, this is done
deliberately to improve starting and to remove any foreign deposits within its chamber.
Periodic cleaning will give the CORONA plasma ball a diffused 'blue-pink-white' colour.
However, small differences in colour and brightness are normal. If the plasma ball still remains very
bright after the start up phase you should clean the electrode as described in section 3.5 of this
manual.
k. After the starting process has ended the CORONA switches to normal operation (its plasma ball
brightness and size is reduced). Please note, it can take a few minutes for the plasma ball to form a
complete circle.

LANSCHE AUDIO OPERATING INSTRUCTIONS No.3.2
Page 15 / 17
4. Miscellaneous Instructions
4.1. Warm-Up Phase
To develop its maximum potential output, the speaker requires a warm-up period of about 15–20
operating hours after being transported. During this time, the properties of all mechanical parts shift
until they finally attain the values defined during the development of the speaker. In other words, the
suspension of the chassis becomes more flexible, exerting a positive influence on the quality of sound
reproduction.
4.2. Load Rating
The load rating of the No.3.2 is especially high due to its design and the materials used in its
construction. The speakers can be subjected to very high volumes without a reduction in sound
quality (after the warm-up phase). Because of the efficiency of the No.3.2 speakers, they are also
suitable for use with high-quality but lower-output amplifiers. However, the following point must be
taken into consideration:
Amplifiers with very low output and amplifiers with equalizers or tone controls can produce distorted
signals in the higher frequencies at very high volumes. This clipping effect can even permanently
damage the best speaker technology. Damage caused in this way is not covered by the warranty.
4.3. Caring for Your Speakers
To get the most out of your LANSCHE AUDIO speaker system, please observe the following
instructions: Do not place the speakers in direct sunlight.
Avoid extreme temperature fluctuations and protect the components from humidity. Do not clean
the housing surfaces with any substances that contain alcohol or are abrasive. Use the lint-free cloth
provided instead. Whenever cleaning your system, be sure to switch off the entire chain of devices.

LANSCHE AUDIO OPERATING INSTRUCTIONS No.3.2
Page 16 / 17
6. General Notes on Safety
1) - Safety and operating instructions
Please read all safety and operating instructions carefully before operating the device. Never open
the housing. If any damage occurs, please contact an authorized LANSCHE AUDIO dealer.
Avoid submitting the switches and connection elements to excessive force.
2) - Warnings
All warnings on the device and in the operating instructions should be complied with specifically.
3) - Power sources
The local voltage must correspond with the voltage indicated on the serial number plate of the
No.3.2 which is located on the bottom plate. LANSCHE AUDIO cannot be held liable for damage
caused by operating the device with a different voltage than the one specified.
4) - Protecting the power cable
Power cables are to be laid such that they will not be damaged. Special caution should be given to
all plugs, splitters, and points of connection.
5) - Overload
To prevent fire and electric shock, avoid overloading the electric sockets, extension cables, etc.
6) - Ventilation
Never cover the top of the speaker (1) cover or block the air inlet holes (3). These are cooling vents
for the CORONA.
7) - Sources of heat
Never place the devices near sources of heat (radiators, heat accumulators, stoves, or other heat-
generating devices).
8) - Water and humidity
To prevent the danger of electric shock, a device should never be operated in the vicinity of water or
near a bathtub, sink, or swimming pool.
9) - Penetration by objects and liquids
To eliminate dangers from fire or electrical shock, no foreign objects or liquids may be allowed to
enter into the housing. Never expose these speakers to rain or very humid conditions.
10) - Cleaning
Before cleaning, disconnect the AC power plug. Generally speaking, only the surface of the cabinet
needs to be dusted. Never attempt to clean your No.3.2 with a solvent, as this could damage its
finish. Please use a clean, dry cloth such as one made from microfiber.
11) – Speaker supports
Never place the speaker on an unstable stand, tripod, bracket, table, or similar object. A falling
speaker could seriously injure a child or adult, in addition to damaging the speaker itself. Mount the
speakers only according to the dealer’s instructions.
12) - Transport
The devices should be transported using great caution. Abrupt stops, exaggerated force, and
uneven surfaces can all cause the devices to tip over. Make sure that there are no cables under the
carpet that could be damaged by the spikes.

LANSCHE AUDIO OPERATING INSTRUCTIONS No.3.2
Page 17 / 17
Do not apply excessive force on the spikes when positioning the speakers, as this could cause them
to be torn off from the bottom plate. When lifting the speakers, make sure not to injure yourself on the
spikes. When you transport your speakers, be absolutely sure to first remove the AC power cable and
any other cables connected to the No.3.2. Always apply the pulling force to the plug itself and never
to the cable.
13) - When not in use
If the speakers will not be in operation for an extended period of time (for example, during a
vacation), disconnect the AC power plug. If a storm is expected, it is also advisable to disconnect
the AC power plug and speaker cable to avoid damage caused by lightning.
14) - Service
The user should not conduct any work on the speakers apart from the operations described in these
instructions. The speakers are to be opened and repaired by qualified service personnel only.
15) - Damage
The speaker should be immediately switched off and trained personnel should be consulted if:
a. Power cords or plugs are damaged;
b. Objects or liquids have found their way into the speaker;
c. The speaker was exposed to rain.
d. The speaker does not function properly, despite following the operating instructions. Only adjust
the operating elements as described in the instructions. Improper settings of other operating
elements can lead to damage that must then be repaired by a qualified technician in order to
return the speaker to its normal operating condition;
e. The device has fallen or been damaged;
f. The device does not function properly or displays an obvious drop in performance.
16) - Replacement parts
If replacement parts are required, make sure that service technicians use parts recommended by the
manufacturer or parts that possess the same technical characteristics as the originals. Unauthorized
replacement parts can lead to fire, electric shock, or other hazards.
17) - Mains fuses
The electronic components of the Lansche No.3.2 speaker system are protected against damage in
several ways. To prevent fire, use only fuses of the type and rating specified by the manufacturer. The
technical data for the fuses in the individual voltage ranges can be found on the label located on
the bottom plate.
18) - Magnetic leakage fields
Each device produces a magnetic leakage field. For this reason, we recommend a minimum
distance of 0.5 m between the speakers and magnetically sensitive items (televisions, magnetic
wristwatches, computer screens, audio and video tapes, etc.).
19) - CORONA plasma tweeters
a. The CORONA plasma tweeter emits a bright light (plasma ball) during the start up operation.
As with any bright light source avoid looking directly at it from a short distance (less than 30 cm).
b. Avoid allowing any objects to enter into the CORONA’s plasma ball chamber (except for
cleaning purpose, see section 3.5 of this manual). This could damage the chamber.
When in operation, there is no danger of a hazardous electric shock if a metallic object should
accidentally find its way into the chamber (inserted by a child, for example).
c. During operation, the temperature at the electrode tip is about 800 °C (1,472 °F). Do not allow
any kind of material (especially flammable materials) to enter the chamber. Even after switching
off, the temperature remains high for at least 30 minutes.
d. During operation, the horn of the tweeter can heat up to 55 °C (130 °F). Depending on the
ambient temperature this can be higher.
e. CORONA plasma tweeters are highly sensitive electronic devices. Please protect them from
mechanical impacts or other mechanical influences.
