SYSTEM DESCRIPTION 3
musikelectronic geithain GmbH ME 801K1
3 System description
High level + large room = big loudspeaker? The ME 801K1 is about to rebut that. Longer reverb, larger
rooms and listening distances easily spoil the fun for the ambitious music listener. The ME 801K1
makes use of a few things out of the bag of tricks lled throughout the long history of the company
with much technical know how.
As well as the legendary RL 901K the ME 801K1 uses a 16-inch long-throw woofer. ME Geithain’s
typical cardioid dispersion behaviour in the lower frequency range from 25 Hz to 250 Hz minimizes
reections behind the speakers so positioning is less critical. A 6.5-inch high-performance midrange
cone driver and an array of three 1-inch dome tweeters are coaxially mounted in front of the low
range driver. This arrangement ensures the directivity that is needed in large rooms to minimize
reections and provides an irresistible spatiality. Their high sensitivity offer not only impressive level
and dynamic capabilities but also low distortion. The consequent use of the coaxial technology has
another undeniable advantage: the size of the speaker is obviously reduced. Thanks to housing the
amplier in its own cabinet the dimensions are further reduced. The electronic part consists of three
PWM ampliers and an analogue lter equipped with a room equalization lter to adjust the speaker
to the position in and the properties of the listening room. The ampliers deliver a power of 1000 W
in the low frequency channel and 500W each in the mid and treble channels. Therefore dynamical
limits of the whole system are no concern.
Despite all of these features the ME801K1 sticks to its roots and has all the virtues our customers
value: neutrality, homogeneity, low coloration and longevity.
An elegant stand for the ME801K1 is available upon request.

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 inuences there are no claims under guarantee.

POSITIONING 7
musikelectronic geithain GmbH ME 801K1
5 Positioning
Our speakers do not impose special requirements neither in stereo nor in multichannel set-ups.
Nonetheless speaker positioning has in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 offer 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 affected. 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 reections are unavoidable.
The speakers ME801K1 however utilize cardioid radiation characteristics with rearward attenuation
greater than 10dB. 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 8
musikelectronic geithain GmbH ME 801K1
5.2 Stereo operation
The optimum position of the speakers in your listening environment is the so-called stereo triangle
(see 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 6 m (19′8″)
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 … 6 m (9′10″ … 19′8″)
;Adjust the speaker horizontally to the height of the ear at the listening position

POSITIONING 9
musikelectronic geithain GmbH ME 801K1
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 … 6 m (9′10″ … 19′8″)
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 10
musikelectronic geithain GmbH ME 801K1
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-amplier (Ua= 1 V ... 5 V; Ri < 600 Ω).
6.1 Connecting the ME 801K1
The amplier of the ME 801K1 is housed in a separate enclosure. Every amplier is paired to exactly
one speaker by the same serial number. Ensure installation in pairs.
Ensure sufcient convection at the heatsink. Therefore the amplier should be used standing upright.
For a horizontal installation we recommend to use the RL-Amplier / RL-Amplier 2.
To connect the Speaker to the amplier use only the shielded Speakon cable that is part of the
delivery contents!
Ensure that the latch snaps audibly in place in the sockets of the speaker and the amplier by turning
the plug clockwise. Connect your signal source with the amplier through the XLR socket.
To release the connector cable from the speaker and the amplier,slide the latch on top of the
connector back and turn the connector anticlockwise.
Before start-up check the mains voltage state on the backside of the amplier. If your local mains
voltage does not match the specication of the device,please refer to your retailer or direct
distribution. When the stated and your local mains voltage comply connect the mains connector of
the amplier to the socket with the included mains cable.

6.2 Cable connection
The input of the integrated amplier is electrically balanced. When your signal source also utilizes
balanced connectors, please use a cable wired as stated in the table:
Balanced connector
(ampli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 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.
6.6 Bass extension
The speaker enables the connection to a subwoofer from the BASIS series. Use the output connector
at the amplier to utilize this option. By the bass extension an acoustical power enhancement in the
lower frequency range is achieved and results in an even sound propagation especially in acoustically
less damped rooms.
