1 Introduction
Dear customer,
Thank you for your trust you have put in us by buying these speakers. You decided upon a quality
product that in regard to tonal and technical characteristics complies to the utmost expectations.
Theusualburn-inperiodisnotrequired,becausethespeakersarearticiallyagedin-house.
Please read the technical description and manual to take advantage of the capabilities
of these speakers and ensure safe operation.

SYSTEM DESCRIPTION 4
musikelectronic geithain GmbH ME 801K1
2 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 ME801K1 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 to 250Hz minimizes
reectionsbehindthespeakerssopositioningislesscritical.A highefciency6.5inchmidrange
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 colouration and longevity.
An elegant stand for the ME801K1 is available upon request.

3.5 Cleaning
The speaker is made of real wood veneer and be nurtured in the same way as furnishings. We advice
quality wax polish to ensure durability of the veneer. Surfaces can also be cleaned with tidy, slightly
damped, fuzz-free, smooth cloth.
3.6 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
4 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.
4.1 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 however utilize cardioid dispersion behaviour 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 20cm (7,9‘‘) to walls and furniture should be
ensured. Avoid corner installations because unwanted bass accentuation could arise.

POSITIONING 8

4.2 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 3m (10 ft) or more than 6 m (20 ft) should
be avoided. For precise, spacial reproduction turn the speakers inside, directed to the hearing zone.

4.3 Surround operation
In surround operation the stereo triangle (see Stereo operation) is extended to a circle. The hearing
zone is the center of this circle. Position all speakers in the same distance to the hearing zone. The
center 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 center and rear speakers
should be about 110° - 120°.

CONNECTING THE SPEAKERS 10
musikelectronic geithain GmbH ME 801K1
5 Connecting 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oftheampliercaseisinposition“OFF”.Onlywhenyour
speaker is completely connected (see chapters 5.1 and 5.2) you can take the device into operation
by use of the mains switch.
The speaker is connectable to any signal source (UA= 1 Volt ... 5 Volt; Ri< 600 Ohm).
5.1 Connection of the speakers with the separate amplier
OnlyusethesuppliedSpeakoncabletoconnectthespeakerswiththeirseparateampliers!
Thespeakerandtheseparateamplierarepairedbythesameserialnumber,printedonthebackof
each device. Connect the corresponding units with the Speakon cable. Ensure that the latch snaps in
placeinthesocketsofthespeakerandtheamplierbyturningtheplugclockwise.
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.
5.2 Mains connection
Check the mains voltage state on the backside of the device. If your local mains voltage does not
matchthespeci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.
5.3 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:
