System description 3
musikelectronic geithain GmbH ME 802 K
3 System description
The 4-way concept of the ME 802K comprises three 10-inch woofer systems, a 6.5-inch high-
performance midrange system and a tweeter array with three vertically arranged 1-inch dome
tweeters. The directivity of the system has been optimized for listening distances of between three
and eight metres, rendering a natural sound image in stereo and multichannel operation. Two 1000
W and two 500 W amplifi er modules supply the bass, mid and treble channels with suffi cient power.
The resulting overload safety ensures that even signals with highest peak levels are not limited. Also,
sound pressure levels of up to 125 dB can be performed without audible distortions throughout the
eff ective frequency range. A room compensation network, integrated into the amplifi er electronics,
allows control of the room-dependent frequency response.
The vertical arrangement of the 10-inch woofers provides a directivity index that ensures realistic
bass presence even at listening distances of up to eight metres. Our reliable K Technology minimizes
rearward-directed room refl ections in the bass range and simplifi es the positioning of the ME 802K
in the listening room. If required, the three 10-inch bass units can be operated as subwoofers via
the LFE input.
The low coloration and low distortion of the 6.5-inch high-performance midrange system result from
the intelligent combination of several construction details. The cone loudspeaker, for example, runs
without contact to the enclosure, thus avoiding the problem of cabinet resonances. Instead, the
midrange system is operated with a rearward-directed acoustic fl ow resistor in order to achieve the
desired directivity.
Frequently used wave guides in front of tweeter systems make directivity control easy. However,
they tend to produce unavoidable coloration due to short-time refl ections on the inner horn surface.
We take a diff erent approach by using a tweeter array and doing without horn loudspeaker systems
for sound level enhancement. The tweeter unit that is arranged coaxially in front of the midrange
system guarantees the trademark low coloration reproduction of sound events in our loudspeakers.
All these features make the ME 802K so unique on the loudspeaker market. It is ideal for large
listening distances and for acoustically less attenuated rooms.

4.3 Unboxing
The speakers are shipped in proper condition. Unpack the speaker carefully and check for visible
damages. In case of damages report them to your retailer. Keep the packaging, in case the speaker
has to be transported in the future.

4.5 Cleaning
The speaker is made of real wood veneer and needs to be nurtured in the same way as furnishings.
We advise quality wax polish to ensure durability of the veneer. Surfaces can also be cleaned with
tidy, slightly damped, fuzz-free, smooth cloth.
4.6 Environmental conditions
Ensure the following environmental conditions in your listening room:
Operating temperature + 15°C ... + 35°C (59°F ... 95°F)
Storage temperature range - 25°C ... + 45°C (- 13°F ... 113°F)
Relative humidity 45 % ... 75 %
4.7 Guarantee acknowledgements
Opening the device by unauthorized personnel leads to all claims under guarantee expire. In case of
destruction by overload, misuse or outside infl uences there are no claims under guarantee.

Positioning 6
musikelectronic geithain GmbH ME 802 K
5 Positioning
Our speakers do not impose special requirements neither in stereo nor in multichannel set-ups.
Nonetheless speaker positioning has infl uence on listening impression because every room is
individually designed and furnished. The following advices are just guidelines that ease proper
positioning. In addition we off er a measurement service to take advantage of the capabilities of your
listening environment.
5.1 Positioning near walls
When speakers are installed near walls sound quality is physically aff ected. Every customary speaker
behaves as a punctual sonic source in the low frequency range, with sonic waves spherical radiated
without any constructional measures. Back wall refl ections are unavoidable.
The speakers however utilize cardioid radiation characteristics with rearward attenuation greater than
10 dB. Because of this structural measurement installation near walls is considerably less critical. For
optimum listening experience a minimum distance of 20 cm (7.9″) to walls and furniture should be
ensured. Avoid corner installations because unwanted bass accentuation could arise.
Minimum distance to wall b ≥ 20 cm (7.9″)

Positioning 7
musikelectronic geithain GmbH ME 802 K
5.2 Stereo operation
The optimum position of the speakers in your listening environment is the so-called stereo triangle
(see fi gure). The base distance between the speakers and the distance to the hearing zone form
an equilateral triangle (stereo triangle). A distance less than 3 m (9′10″) or more than 8 m (26′3″)
should be avoided. For precise, spacial reproduction turn the speakers inside, directed to the hearing
zone.
Distance between speakers and your listening position a = 3 m … 8 m (9′10″ … 26′3″)
Adjust the speaker horizontally to the height of the ear at the listening position

Positioning 8
musikelectronic geithain GmbH ME 802 K
5.3 Surround operation
In surround operation the stereo triangle (see Stereo operation) is extended to a circle. The hearing
zone is the centre of this circle. Position all speakers in the same distance to the hearing zone. The
centre speaker is positioned in the middle between both front speakers. Pay attention to positioning
the front and rear speakers horizontally along one plane. The angle between centre and rear speakers
should be about 110° - 120°.
Distance between speakers and your listening position a = 3 m … 8 m (9′10″ … 26′3″)
In case installation in the prescribed way is not possible in your listening room most decoding
devices allow adjustments of single speakers.

Set-up the speakers 9
musikelectronic geithain GmbH ME 802 K
6 Set-up the speakers
In this chapter we inform you how to connect your speakers to mains and your signal source. Ensure
that the mains switch on the backside is in position “OFF”. Only when your speaker is completely
connected (see chapters 6.1 and 6.2) you can take the device into operation by use of the mains
switch.
The speaker can be connected to every common pre-amplifi er (Ua = 1 V ... 5 V; Ri < 600 Ω).
6.1 Mains connection
Before start-up check the mains voltage state on the backside of the device. If your local mains voltage
does not match the specifi cation of the speaker, please refer to your retailer or direct distribution.
When the stated and your local mains voltage comply connect the mains connector of the speaker
to the socket with the included mains cable.
6.2 Cable connection
The input of the integrated amplifi er is electrically balanced. When your signal source also utilizes
balanced connectors, please use a cable wired as stated in the table:
Balanced connector
(amplifi er)
Balanced connector
(signal source)
Unbalanced connector
(signal source)
XLR XLR RCA
Earth Pin 1 Pin 1 Ring
Signal + Pin 2 Pin 2 Tip
Signal - Pin 3 Pin 3 Ring
When using a signal source with unbalanced outputs (RCA) you need to balance the connecting
cables. This avoids hum and other noise interferences. The table and the following fi gure show the
wiring.

6.3 Adjustment controller
The “Level” controller is used for level adjustment over the full frequency range.
6.4 Status indication
The two-coloured LED at the front of the speaker is used as status indicator of the device.
LED green: indicates normal operation of the device
LED red: indicates the operation of the overload protection circuit;
Output power limitation to protect the components from overloading
6.5 LFE input
The LFE input is useful if only the two lower woofers should exclusively reproduce the LFE channel.
