Using this handbook
This handbook has been designed to give you all the
information you need to install, connect, set-up and use the
Arcam DiVA DT91. The remote control handset supplied with
the equipment is also described.
It may be that the DT91 has been installed and set-up as
part of your Hi-Fi installation by a qualied Arcam dealer.
In this case, you may wish to skip the sections of this
handbook dealing with installation and setting up the unit,
and move directly to the sections dealing with using the
player. Use the contents list to guide you to these sections.
Safety
Safety guidelines are set out on page 2 of this handbook.
Many of these items are common sense precautions, but for
your own safety, and to ensure that you do not damage the
unit, we recommend that you read them. This is a class 1
product and requires an earth connection.

Positioning the unit
n Place the DT91 on a level, rm, surface, avoiding direct sunlight and sources of heat or damp.
n Avoid placing the DT91 on top of a power ampli er or other source of heat.
n The DT91 may run warm during normal operation, so avoid placing the DT91 in an enclosed
space such as a bookcase or closed cabinet unless there is good ventilation.
n Make sure the remote-control receiver in the centre of the front panel display is unobstructed,
otherwise remote-control will be unreliable. If line-of-sight is impractical, a remote-control
repeater can be used with the rear panel connector. (see below).
n Avoid placing a record deck on top of this unit. Record decks are very sensitive to the noise
generated by mains power supplies which will be heard as ‘hum’ if the record deck is too close.
Connecting up
Analogue audio outputs
Two pairs of stereo analogue outputs are
provided by the DT91, both of which provide
the same signals. Connect one pair of these
outputs to your ampli er using a suitable
stereo phono cable. The second output pair
may be connected to some other audio
device, as desired, such as a cassette deck.
Note that interconnecting cables are not
supplied with this tuner. We recommend
the use of high-quality screened cables,
since inferior-quality cables will degrade
the overall quality of your system. Use
only cables that are designed for an audio
application as other cables will have
different impedance characteristics that will
degrade the performance of your system
(for example, do not use cabling intended
for video use to carry audio signals).
All cables should be kept as short as is
practically possible.
It is good practice when connecting your
equipment to make sure that the mains
power-supply cabling is kept as far away as
possible from your audio cables. This avoids
unwanted noise in the audio signals.
Digital outputs
The DT91 is tted with both optical and co-axial
digital audio outputs; the two carry the same
information at all times. If you wish, these can
be connected to an external DAC or your AV
receiver, which may enhance the nal audio quality.
Alternatively, they can also be used to connect this
tuner to a digital recording device (such as a CD-R
or Minidisc recorder) for direct recording.
When listening to a DAB radio station, these outputs
carry audio with a sample rate of 48kHz; when an
FM station is being received, the sample rate is
32kHz.
Remote control in
If you are using this tuner
with an ampli er that also
features a remote bus
(such as the Arcam DiVA
AVR300) you can connect
the REMOTE OUT of the
ampli er to the REMOTE IN
of the tuner using a 3.5mm
jack lead.
This allows the tuner to be
positioned out of sight while
still offering remote control,
since commands are passed
through the ampli er. It
can also be used to route
control signals for multi-
room use.
The remote control input
requires a mono 3.5mm
jack, with the tip active and
the sleeve grounded.
The remote control signals
must be in modulated RC5
format, with a voltage level
of between 5V and 12V.
Aerial input socket
The coaxial cable from
the aerial should be tted
with a 50Ω F-type (screw)
connector. Connect this to
the aerial socket on the
back of this tuner, pushing
the pin into the centre of
the socket, then screwing
on the cover to lock in
place.
Take care not to over-
tighten the F-connector
( nger tighten only – do
not use tools as this may
damage the circuit board
behind the connector).
See ‘Setting up the aerial’
for further information on
the aerial type to use.
Mains lead
The appliance is normally supplied with
a moulded mains plug already tted to
the lead. If for any reason the plug needs
to be removed, it must be disposed of
immediately and securely, as it is a potential
shock hazard when inserted into the mains
socket.
Check that the plug supplied with the unit
ts your supply and that your mains supply
voltage agrees with the voltage setting
(115V or 230V) indicated on the rear panel
of the unit.
If your mains supply voltage or mains plug
is different, or you require a new lead,
please consult your Arcam dealer.
PLUGGING-IN
Push the plug (IEC line socket) of the power
cable supplied with the unit into the socket
(POWER INLET) in the back of the unit.
Make sure it is pushed in rmly.
RS232 interface
The serial interface
is available for
controlling the DT91
from a computer
or other controller.
The remote control
protocol is described
in the Appendix to this
handbook.
Supply voltage
Move the slider to 115V
or 230V, depending
on the mains supply
voltage in your area.

Setting up the aerial
Your new Arcam tuner is capable of superb reception, but only if it is receiving a
good quality transmission signal.
If the transmission signal is strong in your area then the supplied indoor aerial
may be sufcient (it should be hung on a wall with both wires fully stretched out
vertically). An external aerial is recommended in order to receive the highest number
of services.
DAB transmissions can be in either ‘Band III’ or the ‘L-band’ (or both). To
determine the transmission frequency in your area, contact your dealer, or refer to
www.WorldDAB.org. In Band III transmission areas, use a multi-element Yagi
aerial if you are a long way from a transmitter, or use an omnidirectional or folded
dipole aerial if you are close to more than one transmitter (in the U.K., a Band III
region, this should be mounted with the elements vertically, as the transmissions are
vertically polarised). If the DAB services in your area are transmitted on L-band then
consult your dealer for advice on the best aerial to use.
You may have noticed that, although the DT91 supports both DAB and FM radio,
there is only one aerial connector on the rear panel. If you wish to feed signals from
both aerial types into the unit, a low-loss signal combiner must be used, as shown in
the diagram. Otherwise, choose the aerial type for the medium you use most often.
Whether you decide to install an external aerial, or opt to use the supplied ribbon
cable, it should be connected to the F-type (screw) connector labelled AERIAL INPUT
on the rear of the unit.
The type of aerial you should use depends on your listening preferences and the local conditions.
If you listen exclusively to FM transmissions, for example, and the FM signal strength is strong
in your area, then a simple omni-directional aerial mounted in your loft or on your roof may be
sufcient. Listening to DAB in a weak signal area will require a high-gain, roof-mounted aerial.
For the best reception of both DAB and FM signals, an aerial combiner box may be required
(as shown in the diagram above). This combines the signals received by two aerials (one for
DAB, the other for FM), into one cable that then connects to the DT91. If an aerial combiner
is not used, the single aerial chosen for both DAB and FM reception may not give optimum
performance in some regions.
For the best advice, we recommend that you contact your local Arcam dealer or an aerial
installation expert.

Using your tuner
Searching for radio stations: DAB
When using the DAB tuner section for the rst time, you should perform a search to nd the available
services in your area. You may also wish to repeat the search periodically to discover if any new
ensembles (i.e. groups of services) have gone on air, or if you move the tuner to a different area.
To perform a search
Ensure that the DT91 is in DAB mode (by pressing the DAB/FM button until ‘DAB’ is shown on the
display), then press SEARCH or MENU; the display shows ‘DAB Setup: Press SELECT to scan’. Press
SELECT to start searching for new stations. The current search frequency is shown on the display as the
search progresses.
A complete search may take three minutes or so to complete. You cannot cancel a search once started.
If no service is found after the search, then either your aerial is inadequate or you may be outside of the
area covered by DAB broadcasts. Please contact your Arcam dealer for further information or advice.
Selecting a service
Turn the rotary controller (or press
4
or
3
on the remote control) to work through the available
stations and to choose the one you wish to listen to. The service displayed will be selected automatically
after a delay of about two seconds.
Deleting services
Under normal circumstances, you should not need to delete services from the DT91. If you move to a
different region, however, or if a station ceases transmission, stations may be shown as available that
can no longer be received.
Individual stations cannot be deleted. To remove stations from the selection list that can no longer be
received, rst press the MENU button; the display shows ‘DAB Setup: Press SELECT to scan’. Turn the
control knob until the display shows ‘DAB Setup: Press SELECT to erase’, then press SELECT. All services
are deleted.
A delete operation should always be followed by a search for available stations (as described previously)
otherwise no DAB radio stations will be available for selection.

Search for radio stations: FM
To perform a search
Ensure that the DT91 is in FM mode (by pressing the DAB/FM button until ‘FM’ is shown on the display).
There are two methods to search for stations in FM mode. If you know the broadcast frequency of the
station you want, turn the control knob on the front-panel until the desired frequency is displayed.
You should then hear the required radio station. An alternative search method is to press and hold the
4
or
3
keys on the remote control. After a delay of about one second, the DT91 begins scanning for
the next available station. On nding a station with a strong enough signal, the DT91 stops scanning,
plays the station and displays the station details.
If no stations can be received, then your aerial is not providing an adequate signal. Please contact your
Arcam dealer for further information or advice.
Switching to mono
In some weak signal areas it can be benecial to force the FM tuner to mono output, as mono requires a
much lower signal strength to produce acceptable results. Press MENU, then turn the control knob until
‘Mono’ is displayed. If the signal strength in your area is good, leave this set to ‘Stereo’.
Programming a preset radio station
Preset stations are available for both DAB and FM. Up to 16 stations can be stored as presets.
First select the radio station you wish to assign to a preset. Press STORE 1–8 or STORE 9–16, then press
the appropriate preset button to store the service.
Selecting a preset
To select presets 1 to 8, press and release the corresponding button. To select presets 9 to 16, press and
hold the corresponding button for two seconds.
Changing the display mode
The bottom line of the display can be set to different modes: programme type, transmission frequency,
dynamic label (scrolling text), data rate (showing service data rate and stereo/mono mode) and signal-
quality (a bar graph). Press DISPLAY MODE on the front panel or MODE on the remote control to cycle
through these display options.
Note that the display modes for DAB and FM are set independently.
Programme type
The ‘programme type’ label is a short description of the type of programme being transmitted, and (if
selected) is displayed below the station name.
Transmission frequency (FM only)
The transmission frequency setting shows the station name (if available), together with the frequency
the station is being transmitted on. This can be useful, in areas where the same station is transmitted on
different frequencies, in ensuring that the correct transmission of the station is selected.
Dynamic label (DAB) / RDS (FM)
This is a 128 character block of scrolling text used by most broadcasters to display programme
information (such as song titles, useful phone numbers and website addresses).
Data rate (DAB only)
The data rate setting allows the data rate of the station, together with the MPEG mode, to be seen. The
data rate is given in kbits/second, with a higher data rate indicating better audio quality. The maximum
data rate supported by the DT91 is 224kbps, but most radio stations are broadcast at 128kbps, or less.
The MPEG mode of the station indicates whether the station is broadcast in stereo or mono.
Signal quality
The signal quality meter is a simple bargraph that gives a quick visual guide to reception quality. For
DAB transmissions, it is an inverse measure of the Viterbi error rate, with zero errors at full scale (all
segments are lit) and 500 errors/second (with all segments off). For FM transmissions, the bar graph
shows a simple analogue measurement of signal strength.
Secondary services (DAB only)
Primary services can have one or more secondary services attached to them. These tend to be
temporary; sporting events such as football matches, for example, may be broadcast as secondary
services. Services that have secondary services attached to them are indicated by a ‘>’ symbol. Turning
the rotary selector clockwise will then reveal these services. The secondary services themselves are
indicated by a ‘<’ symbol.
You need to select a main service in order to see if there are secondary services attached. Note that only
primary services can be attached to a preset.

Appendix: Serial programming interface
Introduction
This section of the document describes the remote control protocol for controlling the DT91 via the
RS232 interface.
Conventions
n The remote controller is referred to as the ‘RC’.
n All values in this section are hexadecimal values, unless otherwise specied.
Data transfer format
n Transfer rate: 19,200bps.
n 1 start bit, 8 data bits, 1 stop bit, no parity, no ow control.
Command and response formats
Communication between the RC and the DT91 takes the form of sequences of bytes, with all commands
and responses having the same basic format. Communication between the two is full duplex. The DT91
shall always respond to a received command.
Each transmission by the RC shall be at least ve bytes long in the following format:
<STR> <CC> <DL> <Data> <ETR>
n STR (Start transmission): 0x21
n CC (Command code): the code for the command
n DL (Data length): the number of data items following this item, excluding the ETR
n Data: the parameters for the command
n ETR (End transmission): 0xD
Each response by the DT91 shall be at least six bytes long in the following format:
<STR> <RC> <AC> <DL> <Data> <ETR>
n STR (Start transmission): 0x21
n RC (Reply code): = command code
n AC (Answer code): answer code (see below)
n DL (Data length): the number of data items following this item, excluding the ETR
n Data: the information associated with this response
n ETR (End transmission): 0xD
Note that the DT91 shall transmit messages whenever its status changes.
State changes as a result of other inputs
It is possible that the state of the DT91 may be changed as a result of user input via the front panel
buttons or via the IR remote control. Changes resulting from these inputs shall be relayed to the RC
(using the appropriate message type) as they occur.
For example, if the user changed the front panel display brightness using the DISP button on the remote
control, a display message (dened below) would be sent to the RC. A similar action would be taken for
all other state changes.
Answer codes
The following answer codes are dened:
n Command OK 0x1: The command has been accepted and processed completely.
n Command Failed 0x0: The command has failed for some reason.

Installation de l'appareil
n Placez le DT91 sur une surface plane et dure, à l’abri des rayons directs du soleil et de toute
source de chaleur ou d’humidité.
n Veillez à ne pas poser le DT91 au-dessus d'un ampli cateur de puissance ou de toute autre
source de chaleur.
n Lors du fonctionnement normal du DT91, sa température augmente. Veillez donc à ne pas placer
l’appareil dans un espace clos, tel qu'une bibliothèque ou un placard fermé, sauf si la ventilation est
suf sante.
n Véri ez que le récepteur de la télécommande, situé au centre du panneau avant de l'unité, n'est pas
obstrué. Ceci risquerait de provoquer le dysfonctionnement du boîtier de télécommande. Si vous ne
pouvez pas dégager une ligne directe entre le récepteur et le boîtier de télécommande, vous pouvez
brancher un répéteur infrarouge sur le connecteur IR du panneau arrière de l'unité (voir ci-dessous).
n Veillez à ne pas poser de platine d’enregistrement sur cette unité. Les platines sont très
sensibles au bruit généré par l'alimentation secteur, qui risque d'être audible à la lecture.
Raccordements
Sorties audio analogiques
Le DT91 est équipé de deux paires de
sorties analogiques stéréo, qui transportent
toutes deux les mêmes signaux. Branchez
l'une d'elles à votre ampli cateur à l'aide
d'un câble stéréo phono approprié. La
deuxième peut être branchée à tout autre
appareil audio de votre choix, par exemple
un lecteur de cassette.
Notez que les câbles de branchement
ne sont pas fournis avec ce tuner. Il est
recommandé d'utiliser des câbles blindés et
de qualité supérieure, a n de ne pas altérer
la qualité générale du système. De même,
employez uniquement des câbles conçus
pour une application audio. L'utilisation
de câbles inadéquats et possédant des
caractéristiques d'impédance différentes
risque de nuire aux performances de votre
système (veillez, par exemple, à ne pas
utiliser de câbles vidéo pour le transport de
signaux audio). Les câbles doivent être aussi
courts que possible.
Il est préférable, lors de la connexion de
l’équipement, de s’assurer que le câblage
de l’alimentation électrique principale est
à bonne distance des câbles audio. Vous
éviterez ainsi les bruits indésirables dans les
signaux audio.
Sorties numériques
Le DT91 est doté de sorties audio numériques optiques et co-
axiales ; les deux transmettent les mêmes informations à tout
moment. Si vous le souhaitez, vous pouvez les brancher à un
convertisseur numérique/analogique (CNA) externe ou à votre
récepteur AV, a n d’améliorer la qualité audio nale. Elles vous
permettent également de connecter ce tuner à un dispositif
d’enregistrement numérique (par exemple, un enregistreur de
CD-R ou MiniDisc) pour l’enregistrement direct.
Lorsque vous écoutez une station radio RAN, ces sorties
transportent le signal audio au taux d’échantillonnage
de 48 kHz. Lors de la réception d'une station FM, le taux
d’échantillonnage est de 32 kHz.
Branchement de la
télécommande
Si vous utilisez ce tuner avec un
ampli cateur également doté
d’un bus distant (par exemple,
l’AVR300 DiVA Arcam), vous
pouvez brancher la sortie
télécommande (REMOTE OUT)
de l’ampli cateur à l’entrée
télécommande (REMOTE IN) du
tuner au moyen d'une che jack
de 3,5 mm.
Vous pouvez ainsi placer le tuner
en ligne indirecte tout en gardant
l’usage de la télécommande,
puisque les commandes sont
transmises via l’ampli cateur.
Cette con guration permet
également d’acheminer les
signaux de la télécommande pour
l'utilisation dans plusieurs pièces.
L’entrée de la télécommande
nécessite une che jack mono
de 3,5 mm, avec pointe active et
mise à la terre de la douille.
Les signaux de la télécommande
doivent être au format RC5
modulé, avec une tension
comprise entre 5 V et 12 V.
Prise d’entrée antenne
Le câble coaxial de
l’antenne doit être doté
d’un connecteur de type F
50 Ω (à vis). Branchez ce
câble à la prise antenne
qui se trouve à l’arrière
du tuner, en poussant la
broche au centre de la
prise, puis en la vissant
sur le couvercle a n de
bien la xer en place.
Veillez à ne pas trop
serrer le connecteur F
(serrez-le avec les doigts
seulement ; n’utilisez
pas d’outils, car vous
risqueriez d’endommager
le circuit imprimé derrière
le connecteur).
Pour plus d’informations
sur le type d’antenne à
utiliser, reportez-vous à la
section « Installation de
l’antenne ».
Cordon secteur
L'appareil est normalement livré avec
une prise secteur moulée déjà montée
sur le câble. Si vous devez, pour une
raison quelconque, retirer la che,
jetez-la immédiatement avec précaution.
Son branchement sur une prise murale
risquerait de provoquer une électrocution.
Véri ez que la che fournie avec l'appareil
correspond à votre prise secteur et que
la tension secteur correspond au réglage
(115 V ou 230 V) indiqué sur le panneau
arrière de l'appareil.
Si votre tension secteur ou votre prise
secteur est différente ou si vous avez
besoin d’un nouveau cordon, contactez
votre revendeur Arcam.
BRANCHEMENT
Enfoncez la che (prise IEC) du cordon
secteur fourni dans la prise POWER INLET
située à l'arrière de l'appareil. Véri ez
qu'elle est complètement enfoncée.
Interface RS232
L’interface série permet
de commander le DT91
à partir d’un ordinateur
ou de tout autre
contrôleur. Le protocole
de la télécommande est
décrit à l’Annexe de ce
manuel.
Tension d’alimentation
Déplacez le curseur en
position 115 V ou 230 V,
selon la tension secteur
en vigueur dans votre
région.
