beskriver
hvordan
bade
audio-
og
videoprodukterne
i
et
Beolinksystem
skal
programmeres
i
den
valgte
stilling.
Option 1 (Situation 1):
Et
audio-

et
videosystem
placeres
i
samme
rum,
s4
signalerne
fra
Beolink
terminalen
kan
opfanges
af
begge
systemer
samtidigt.
Option 2:
Audio- og videosystemet er placeret i hver sit rum, s&
signalerne fra Beolink terminalen kun kan opfanges af
ét system ad gangen.
Beomaster 6500 i Master Control Link 2-systemet:
Option 3:
Anvendes nar der er to audiokilder i samme rum
(feks.: en MCL2-enhed og en Beomaster 6500).
Option 4:
Anvendes nar der er to audio- og en videokilde i
samme rum (feks.: MCL2, Beomaster og Beovision).
Option 0:
Szetter IR-faler ud af funktion, hvilket kan udnyttes
f.eks. i butiksvinduer eller ved udstillinger. Der kan
dog stadig velges ny option med Beolink terminalen.
Programmering:
Options programmeres med Beolink terminalen, med
Beomaster 6500 i standby:
Tast: (SOUND), Option nr, [STORE]
Display viser: Option nr.
Beomaster 6500 er fra fabrikken programmeret til
option 1.
Stikdaserne Line in/out og AUX/TV:
Line in/out anvendes ved tilslutning af en equalizer.
Husk kortslutningsprop (bestillingsnr. 7220265) nar
equalizer ikke er tilsluttet.
AUX/TV anvendes ved tilslutning af et Beolink-
kompatibelt fjernsyn eller feks. Bang & Olufsen
bandoptager.

Options:
A Beomaster in a Beolink System
Options or situations describe how both the audio and
video products in a Beolink system are programmed
in the chosen setting.
Option 1 (Situation 1):
An audio and a video system are placed in the same
room so the signals from Beolink terminal can be
received by both systems at the same time.
Option 2:
The audio and video systems are placed in separate
rooms so the signals from Beolink terminal can only
be received by one system at a time.
Beomaster 6500 in the Master Control Link 2 system:
Option 3:
Is used when there are two audio sources in the same
room (e.g. an MCL2 unit and a Beomaster 6500).
Option 4:
Is used when there are two audio sources and one
video source in the same room (eg. MCL2,
Beomaster and Beovision).
Option 0:
Puts the IR sensor out of operation; this can be used
in shop windows or at exhibitions for example.
However, new options can still be selected with
Beolink terminalen.
Programming:
Options are programmed with Beolink terminal, with
Beomaster 6500 in standby:
Key: (SOUND), Option no. [STORE]
Display shows Option no.
Beomaster 6500 is programmed at the factory to
option 1.
The Line in/out and AUX/TV sockets:
Line in/out is used for connecting an equalizer.
Remember short-circuiting fuse (order no. 7220265)
when the equalizer is not connected.
AUX/TV is used for connecting a Beolink-compatible
television or e.g. Bang & Olufsen cassette recorder.

DIAGRAMFORKLARING
Pa diagrammerne er der angivet typenumre pa tran-
sistorer og IC’er. Hvis positionsnummeret er efter-
fulgt af en stjerne, skal reservedelsnummeret altid
benyttes, da denne komponent er specielt udvalgt,
f.eks. TR102*,
Positionsnummeret for udgangsforsterkerens venstre
kanal er angivet i paranteser i diagrammet for hejre
kanal.
Komponenttryk og koordinatsystem
De sterste printplader er forsynet med komponenttryk
og et koordinatsystem pa bade print- og kompo-
nentside.
Pa diagrammerne er enhver komponent forsynet med
et koordinatnummer. Dette fortzeller i hvilket
koordinat pa printpladen, komponenten er placeret.
Koordinatnumrene er angivet med mindre skrifttype
end positionsnumrene.
Styrekredslob
I visse styrekredslob er den aktive tilstand angivet
med en funktions- eller bogstavsangivelse. Denne kan
eksempelvis vere ST.BY. = »low« i stand-by-stilling
eller ST.BY. = »high« i stand-by-stilling.
Ledningsforbindelser
Ledningsforbindelserne pa diagrammerne er samlet i
»bundter«. De enkelte ledninger er forsynet med en af
falgende koder:
INTERN FORBINDELSE PA EN DIAGRAMSIDE
Interne forbindelser pa en diagramside angives med
et tal. Knaekket pa ledningen viser, i hvilken retning,
den anden ende af ledningen findes.

EXPLANATION OF DIAGRAM
Type numbers of transistors and ICs are indicated on
the diagrams.
If the position number is followed by an asterisk the
spare part number must always be used because the
component in question has been specially selected,
eg. TR102*.
The position number for the left channel of the output
amplifier are stated in brackets in the diagram for
right channel.
Component print and coordinate system
The largest PCBs have component prints and a
coordinate system on both the print and the
component side.
On the diagrams every component has a coordinate
number. This indicates in which coordinate on the
PCB the component is situated. The coordinate
numbers are written in smaller print types than the
position numbers.
Control Circuit
In certain control circuits the active mode is indi-
cated by a function term or by an abbreviation. This
may be e.g. ST.BY.= low in the stand-by mode or
ST.BY. = high in the stand-by mode.
Wiring Connections
The wiring connections on the diagrams are
assembled in ‘bundles’. The individual wires are
provided with one of the following codes:
INTERNAL CONNECTION ON ONE DIAGRAM
PAGE
Internal connections on a diagram page are indi-
cated by a number. The bend of the wire indicates in
which direction the other end of the wire is found.
CONNECTION TO ANOTHER DIAGRAM PAGE
DIAGRAM C
i I
32 Aa
ae
Forbindelsen til en anden diagramside angives med et
tal samt et bogstav for det diagram, forbindelsen gar
ti
A connection to another diagram page is indicated
by a number as well as by a letter of the diagram to
which the connection leads.

Forsyningsspeendinger
Alle forsyningsspendinger i diagrammerne er
angivet
med
en
pil
og
en
speendingsangivelse.
Eksempel:
Ved siden af speendingsangivelsen star der f.eks.
7 CON. Dette betyder, at den pageldende forsy-
ningsspending gar til 7 steder pa den pageldende
diagramside (7 CON. = 7 connections).
SYMBOL FOR SIKKERHEDSKOMPONENTER
Bang & Olufsen
Supply Voltages
All supply voltages in the diagrams are indicated by
an arrow and a voltage indication.
Example:
“7 CON.”. This means that the supply voltage in
question goes to 7 different places on the diagram
page in question (7 CON. = 7 connections).
SYMBOL OF SAFETY COMPONENTS
JN
Ved udskiftning af komponenter med dette symbol
skal der anvendes komponenter med samme reser-
vedelsnummer.
Den
nye
komponent
skal
monteres
pa samme made som den udskiftede.
MALEBETINGELSER
Alle DC-speendinger er malt i forhold til stel med et
voltmeter med en indgangsimpedans pa 10 Mohm.
DC-spendingerne er opgivet i volt (V), feks. 0,7 V.
Alle oscillogrammer og AC-spendinger er malt i
forhold til stel med et oscilloskop eller et voltmeter
med en indgangsmodstand pa 1 Mohm.
AC-spendingerne er opgivet i millivolt (mV), feks.
660 mV.
When replacing components with this symbol,
components with identical part numbers must be
used. The new component must be mounted in the
same way as the one replaced.
MEASURING CONDITIONS
All DC voltages have been measured in relation to
ground with a voltmeter with an input impedance of
10 Mohms.
The DC voltages are stated in volts (V), eg. 0.7 V.
All oscillograms and AC voltages have been
measured in relation to ground with an oscilloscope
or a voltmeter with an input resistance of 1 Mohm.
AC voltages are stated in millivolts (mV), eg.
660 mV.
