features hands-on programming of
15 timer play and timer record blocks,
once only and on different days in the
week (weekly + individual weekdays).
Timer play includes all internal
sources and stand-by, timer record
includes off-air sources, i.e. radio.
Beocenter 9300
Beocenter 9300 in the home
Beocenter 9300 blends into the room decor thanks to
its beautiful design, exquisite materials and classical
proportions. The ease of integration 1s further
accentuated by the recommended Beolab 8000
loudspeakers with their unique placement flexibility
and sculptural beauty. The placement flexibility is also
evident from the ease of installation: Connect the
mains cables to the Beocenter 9300 and Beolab 8000,
Power Link loudspeaker cables between Beocenter and
Beolab, aerial cable to the Beocenter, remove the two
CD transport screws and the system is ready for use.
In daily use, Beocenter 9300 1s just as uncomplicated,
the microcomputer in the system taking care of all the
tedious switching and monitoring inside the product,
with a clear display readout on all operation, and with
a built-in user guidance by means of interactive menus.
All available operation options are shown at all stages,
from stand-by via source operation and into the more
complex operations such as timer programming. In
stand-by, the lower sensi-touch field shows the
available operation with inscriptions in white for these
functions: select source, load source, programming.

Touch one of the fields with white inscription. e.g. CD,
and the CD starts playing. The upper display now comes
to life, reading out the CD status and the volume status,
while the lower operation field reveals the operation
options available on CD, e.g. track select and search
functions. The same principle of interactive operation
applies to all sources and to the functions involving
more sources, e.g. recording and timer programming.
Beocenter 9300 has been designed
for a lower power consumption than
previous generations of Bang &
Olufsen tricenters. In stand-by the
power consumption is as low as
between 1 and 2 watts, a figure that
has been obtained by the use of a
dedicated stand-by power supply. In
use the power consumption has also
been reduced significantly, tests
showing a reduction of between 25%
and up to 50% compared to previous
generations, depending on source
and measured at an output of 50 mW.
System master
In the Bang & Olufsen product range
three levels of AV integration are
available, the first being the AV
system, where one AV master
controls all sources (Beosystem AV
9000 represents this level). The
second level is the Beolink AV
integration, where two masters are
interconnected and coordinated, the
third level being common operation
of both audio and video with one
single Beolink terminal, but without
AV functions. (e.g. BeoSound
Century and Video System ME 6000)
Beocenter 9300 system features
* Tricenter with FM/AM radio, power amplifier, CD
player and cassettedeck.
* Audio master for Beolink AV integration and in
extended audio systems.
* Power amplifier with 2 x 80 watts long-term max.
output power.
* Loudspeaker and power amplifier protection with
Automatic Power Handling Control.

* Interactive operation.
* Hands-on operation of timer play and timer record
functions (15 programmings, once only, weekdays).
* Easy recording with automatic microcomputer
controlled record level control.
* Battery backup for clock and timer programmings.
* Low power consumption in stand-by and use.
Beocenter 9300 is designed as master in a system, with
full microprocessor control of the internal sources as
well as datalink connected external sources. This
applies both to audio sources connected via the two
sockets TV/AUX and Tape 2/Phono and to video
sources in a Bang £ Olufsen Video System, provided
that the Beovision Video master 1s connected to the
Beocenter 9300 by means of an Audio Aux Link cable.
This type of setup is called Beolink AV integration, in
Which all sources may be operated with the Beolink
1000 terminal, and it opens up a whole new range of
exciting AV functions as described below.
A Beolink AV integrated system may consist of a
Beocenter 9300 and a Video System MX 7000,
including VX 7000 and Beosat LM. Once the Audio

Beocenter 9300
Aux Link cable is connected to the TV/AUX socket on
the Beocenter 9300 and to the Audio Aux Link socket
on the Beovision the integrated AV system is created.
The masters are programmed for AV integration in one
room on delivery, and must be reprogrammed only if
the AV integration is in two rooms. This is known as
an option 2 programming - for a two room setup - and
IS carried out as described in the margin.
The imminent risk of increased operation complexity
caused by the addition of new sources and new
functions has been counteracted by the careful design
of the Beolink 1000 and the Beolink operation
language, where similar functions on different sources
are operated the same way.
What 1s an AV function? An AY function involves the
simultaneous use of both an audio and a video
component in the integrated AV system. AV
reproduction 1s the primary option, AV recording the
second feasible function available.
AV reproduction typically involves sound from the
video sources (TV, satellite, video tape) played via the
loudspeakers of the audio system (to create a broad and
Two of the AV functions available
with Beolink AV integration:
Above: reproducing video sources
via the loudspeakers of the audio
system, in the example reception of
satellite radio. All other video
sources could be used also, and the
sound from these sources recorded
on the cassettedeck in the Beocenter
9300. Operation: AV, then video
Below: reproduction of audio sources
via the Video System, a most useful
function if you want to make an audio
only recording on the VX 7000.
Operation: AV, then audio source. If
you want to record on the VX, press
the RECORD button twice and the
recording starts.
Note: In both illustrations we have
simplified the system by showing
only one loudspeaker
impressive sound image) either as an accompaniment
to the video on the screen, or with inactive screen, 1f
you only want the music. Reception of satellite radio
with reproduction via the speakers of the audio system
and inactive screen is another logical option in a
Beolink AV system.
AV recording may involve the use of either the
cassettedeck or the VX video tape recorder. Examples
could be the recording of music from satellite TV or
radio on the cassettedeck or using the VX video tape
recorder for the recording of audio only in the very
high sound quality possible on a hifi video tape
recorder, and with up to 8 or 10 hours of music on one
single tape.

Beocenter 9300
AV integration in one and two rooms
Audio functions and sources are operated as
previously, either hands-on or via the Beolink 1000,
video functions and sources are also operated as
previously, with all operation on the Beolink 1000 or
via on-screen menus. Operation of the new functions,
the Beolink AV functions, is via the Beolink 1000
terminal and involves the use of the AV button.
1. Reproduction of a video source via the loudspeakers
of the audio system: Press the AV button, then the
video source you want to listen to, TV, SAT or
V.TAPE. You may now operate the source as usual. If
thc operation is from stand-by, there will be no picture
on the screen, if the Video System is already active,
there will be both picture on the screen and sound via
the audio loudspeakers.
2. Reproduction of an audio source via the video
system: Press AV, then select the audio source,
RADIO, CD, A.TAPE or PHONO. You may now
operate the source as usual. If the operation is from
stand-by, there will be no picture on the screen, if the
Video System is active, you will see a picture on the
screen from the video source and hear the sound from
the audio source. This function is useful for simulcast,
that 1s 1f the TV programme is transmitted with mono
sound only but with the soundtrack for the TV
programme simultaneously available in stereo on an
FM radio programme.
3. Recording follows the same lines: summon the
source onto the system where your recorder 1s, and
start the recording on the Beolink terminal.
An example could be the recording of a radio
programme directly on the VX video tape recorder:
from stand-by, press AV, then RADIO, and a radio
AV integration in two rooms
programme 1s presented by the speakers of the Video
System. Press RECORD twice and the recording starts
on the video tape recorder.
Recording the sound from a video source on the
cassettedeck: press AV, then e.g. SAT, and a SAT
programme 1s presented by the speakers of the audio
system. Press RECORD twice and the recording starts
on the cassettedeck.
The Beocenter 9300 may also be placed in one room
and the Video System in another. For AV integration
they must be interconnected with the Audio Aux Link
cable as previously described, and reprogrammed to
Option 2. The audio sources may now be played back
via the Beovision TV, and recorded on the VX video
tape recorder. The video sources may also be played
back via the loudspeakers of the audio system, and
recorded on the cassette deck.
The Option 2 programming tells the system that the
masters are in each their room. When you are facing
the Beocenter 9300 1t 'knows' that the Video System 1s
in another room and now regards these sources as
audio sources. When you are facing the Video System
it too 'knows' that an Audio System is connected and in
another room. Both masters regard the system in the
other room as sources. The consequence of this is that
operation is very straightforward: select the source, and
it starts playing.
A few examples: in the room where the Video System
is placed, you would like to listen to a CD; in stand-by
press CD and the CD starts playing with inactive
screen - an operation which 1s identical to that in the
room where the Beocenter 9300 1s placed. If you want
to listen to the TV news in the Beocenter 9300 room,
simply press TV and select the program number, and
you will hear the news - again the operation is identical
in the two rooms.

AV distribution
Beolink as a concept covers both AV integration and
AV distribution, that is distribution of sound and
picture from the central room system to other rooms in
the home for reproduction via one of the X-tra room
products or kits, LCS 9000, X-tra speaker kit, X-tra
Active speaker kit or X-tra TV kit, and with operation
from these room by means of the Beolink 1000
terminal. Beocenter 9300 is designed as the central
room audio system in a Beolink audio distribution
system, and if Beosystem 9300 is part of an integrated
AV system as previously mentioned, it may also serve
in the master role for AV distribution.
For audio distribution, each local room is equipped
with an X-tra product or kit, and a special MCL cable
connects the kit with the audio master in the central
room, for audio and data signals, while a coax cable is
used for the distribution of video signals from the
central room VX video tape recorder, to rooms with
X-tra TV kits.
MCL ~~
Beolink 1000 is used for the operation. Compared to
the central room, operation in the local room has
deliberately been concentrated on the daily functions -
to give an easier and more secure operation of a system
which is in effect invisible to you in the local room.
Local room operation
The CD and tape compartments are
available for loading and unloading
by the touch of a finger on the
operation panel
Indoor AM
All sources that are datalink connected to the central
room audio master may be selected with the Beolink
1000. This also applies to video sources, if the central
room system is an AV integrated system.
This 1s the operation available from the local room
with a Beolink 1000 terminal: Source selection, source
operation, €.g track selection, search functions, step
and wind/rewind, turn functions, for example tuming an
audio tape from one side to the other, and selection of
language on satellite TV, stereo/mono selection and
sound track on video tapes, volume adjustments and
sound adjustments. Tuning and timer programming is
not available from the local room, nor is presetting or
clearing of program numbers.
The sources
Beosystem 9300 contains three sources: FM/AM radio,
CD player and cassettedeck.
The FM tuner is of the phase lock loop type and a very
compact construction. Tuning is in steps of 50 kHz, for
optimum reception of stations that do not adhere to the
standard 100 kHz steps, e.g. certain cable network FM
stations. Tuning to FM stations can be carried out
either as a standard tuning search or directly to a
known frequency. The AM receiver is optimized for an
indoor loop antenna (order no. 8720038).
If you select a preset above 19, e.g.
24, the small display to the left
confirms your selection, then briefly
shows the frequency of the radio
programme before reverting to show
the selected preset, in this case 24.
CD player
Track select programming
Beocenter 9300
Beocenter 9300 has 30 presets, FM/AM, which may be
stored in any order. The presets may also be cleared, a
function that is helpful especially if identical stations
are stored on different program numbers. The display
at the top shows the presets, up to 19, and if stations
have been preset above this number a + is displayed.
The preset currently selected blinks slowly. FM
stations may be preset with information on mono/stereo
and fine tune adjustments.
The most important features of the CD player are:
* Horizontally placed CD mechanism in compartment
with motorized cover.
* Playback of 5" and 3" discs.
* Track search, track select programming, step function.
* Spring suspended deck.
* Bitstream conversion system.
The CD mechanism is mounted on the floating inner
chassis. The disc is automatically clamped when the lid
closes, and once it is clamped the disc 1s only in contact
with the spindle of the CD mechanism. The clamp
mechanism is a pressure type with no physical contact
between the CD mechanism and the chassis when the
clamp engages the compact disc, locking 1t into place,
and combined with the substantial weight of the
Beocenter 9300 this means that CD playback 1s
virtually immune to vibrations coming from the
outside, e.g. caused by jolts, knocks etc.
Programming a track selection is carried out directly on
the Beocenter 9300. Both STORE and CLEAR
programming is possible, STORE being used to compile
some tracks from a CD, CLEAR being the logical
choice if you want to leave out a few tracks. STORE
and CLEAR results in playback of the selected tracks in
chronological order, e.g. 1, then 4, 6,9, 12, 21. Up to
50 tracks may be included in a sequence. Tracks will
only be played once in a sequence.
Display readout
Bitstream conversion
The new generation bitstream D/A
conversion system and error
correction means that the CD player
in Beocenter 9300 is more immune
to damaged compact discs, e.g.
scraiches, than previous generations
of CD players.
Je el
+ oje]
The display in the middle of the glass top panel shows
the number of tracks on the CD, max. 19 (track bar). If
a selection of tracks has been programmed, the track
bar shows only the programmed tracks. The display to
the right shows the playing time of the track in
progress ın minutes and seconds, and ıf there are more
than 19 tracks on the CD this is indicated by a + on the
track bar. Track numbers above 19 are displayed
briefly in the right display, before it reverts to playing
time readout. The track in progress is indicated by a
blinking digit on the track bar.
The CD player in Beocenter 9300 contains a bitstream
conversion system like the one pioneered in the CD
player in BeoSound Century. Multibit converters pose
great demands on the precision in the integrated circuits
used for the converter. They also require very narrow
tolerances and are sensitive to the surrounding
temperatures and aging.
Bitstream converters are less critical in production and
use compared to multibit converters at a comparable
price level. In a bitstream converter one bit is converted
from the digital to the analogue domain at a time, so all
bits get equal significance, and errors during conversion
are less significant and may easily be corrected by the
error correction circuitry.
Bitstream technology relies on the ability of transferring
individual bits with very high speeds, 256 calculations
per second for every sample, in total 256 x 44,1 kHz or
a total of 11,289 MHz. The bitstream converter is a
standard type, but is combined with a Bang & Olufsen
analogue filter for improved sonic quality.

Auto track search
Auto Record Level
Beocenter 9300
Important features of the cassette deck are:
« Horizontally placed tape compartment with motorized
* Auto Record Level.
* Auto reverse.
* Auto Track search, step function.
* Auto tape switch.
* HX Pro.
* Noise reduction.
The tape deck in Beocenter 9300 1s optimized for case
of operation and recording. With regard to features the
cassette deck is comparable with the cassette decks in
other Bang & Olufsen products.
Auto track scarch is similar to the function on CD, and
with the same operation: select a track for playback, step
to next or previous tracks. The auto track function
detects new tracks on the pauses between tracks. A
pause is defined as a passage of signals not exceeding
-25 dB for a duration of at least 2.5 seconds.
Auto Record Level ensures an uniform and optimal
recording level from all sources and from tape to tape,
without overload. The Auto Record Level developed
by Bang & Olufsen is based on digital technology and
is monitored and adjusted by the microcomputer.
The recording level is continuously supervised by the
microcomputer, and if a signal overload exceeding a
specified period is encountered, the record level is
automatically adjusted down to a level where overload
of the tape does not occur. The recording then
continues on this level, unless new powerful signals
threaten to overload, in which case the-level is again
adjusted down. The adjustments are unnoticeable in
subsequent playbacks of the tape. The microcomputer
controlled monitoring of the signal is very precise, so
the automatic adjustment of the record level is superior
to adjustments carried out by a supervising person. It
1s also a great convenience in daily life, because you
may start a recording instantaneously, carry it out
without supervision, be sure of an optimum result and
even let persons without technical qualifications make
a perfect recording - every time. In copying a CD (or a
record) onto tape a further convenience 1s that the CD
pauses 1f the tape runs out during the recording, and
that the tape goes to REC PAUSE when the CD stops.
The noise reduction is set to ON on delivery, and can be
set to OFF 1n playback or REC PAUSE. Auto reverse
1s automatic, but may be switched off in playback or
REC PAUSE, e.g. to protect a tape from being
recorded on side 2. The Auto Tape Switch adjusts the
cassettedeck automatically to ferro, chrome or metal
tapes for optimum performance.
