Positioning the unit
Always place the tuner on a level, fi rm surface.
Setting up the aerial
Your new Arcam tuner is capable of superb reception but only if
it is receiving a good quality transmission signal.
We recommend that a roof mounted aerial is used where
possible, to ensure the best performance. Use a Band III (multi-
element Yagi) array 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. this should be mounted
with all elements vertical as the transmissions are vertically
polarised. Be sure to use a good quality coaxial cable such as
URM43, CT-100 or similar. For Band III use you can use either
50
Ω
or 75
Ω
cable provided it is good quality. Always use 50
Ω
cable for L-band use.
If the signal is strong the supplied indoor aerial may be
suffi cient. It should be hung on a wall with both wires fully
stretched out vertically. However there will be many areas
where one DAB ensemble (i.e. a group of stations transmitted
together) is strong and others are weak. An external aerial is
desirable in these cases in order to receive a higher number
of services. If the DAB services in your area are transmitted
on L-band (1.5GHz) then consult your dealer with regard to the
best aerial to use.
NOTE
: The supplied indoor aerial is suitable only for Band
III, not L-band. An aerial is not supplied in US or Canada.
There is a small aerial made by Bosch which is suitable for
L-Band and Band III and has been used with good results. The
Bosch part number is: F01DE00144

Aerial input socket
The coaxial cable from the aerial should be fi tted with a 50
Ω
BNC plug. Connect this to the aerial socket on the back of this
tuner, turning to lock in place.
Connecting to other equipment
Interconnect cables
Interconnecting cables are not supplied with this tuner. We
recommend high quality cables as inferior quality cables will
degrade the sound quality of your system. Please contact your
Arcam dealer for details of suitable cables.
Digital outputs
Optical and co-axial digital audio outputs are provided. These
can be connected to an external DAC (Digital to Analogue
Converter) in order to enhance the audio potential of this tuner.
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.
NOTE
: The digital output data includes Serial Copy
Management System (SCMS) codes. This allows you to make
one generation of digital recording but further digital copies
will be prevented.
AM/FM tuner audio input
The audio output from a conventional tuner can be connected
here to save an input on the amplifi er. When this tuner is
switched off or is set to bypass mode, this input is routed
straight to the audio output of this tuner.
Remote control in/out
If you are using this tuner with an amplifi er that also features a
remote bus (such as the Arcam Diva A85 or FMJ A22) you can
connect the
REMOTE OUT
of the amplifi 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 as commands are passed through the
amplifi er. It can also be used to route control signals for multi-
room use.
