CONNECTINGTO A POWER SUPPLY

WRONG PLUG I

If the plug supplied with the tuner does not fit your power
supply, see the inside back cover of this handbook for guidelines on
changing a plug, or contact your dealer to obtain a suitable power
cord.

Check that your mains supply voltage agrees with the voltage
setting indicated on the rear panel of the ^ tuner

If your mains supply voltage is different, consult your Arcam dealer or
Arcam Customer Support on 01223 203203.

PLUGGING IN

Push the plug (lEC line socket) of the cable supplied with the tuner
into the socket ©(POWER INLET) in the back of the tuner
Make sure it is pushed in firmly.

CONNECTINGTO OTHER EQUIPMENT

All the sockets carrying messages to other hi-fi equipment (output
channels) are colour coded for identification.

The use of high quality interconnect cables to and from other hi-fi
equipment is recommended to ensure the best sound quality (sonic
performance).
Interconnect cables are not supplied with these tuners.

The left channel sockets are marked L.
The right channel sockets are marked R.

CONNECTING YOUR TUNER TO YOUR AMPLIFIER

0 AUDIO OUTPUTS

There are two pairs of identical outputs provided. Connect
one of these to your amplifier's tuner input using a suitable
interconnect cable. Insert the red phono plug into the
socket labelled ‘R’ for Right and the other phono plug into
the socket labelled 'L' for Left.

The second set of audio outputs can be used to connect to
a second amplifier set up for 'multi room' use or routed to
a tape recorder for‘off air' recording.

Push the plug on other end of the cable into your power supply
socket.

The tuner is double insulated and does not require an earth.

This Is why there is no centre (Earth) pin in the socket (POWER

Setting up the aerials

Your new Arcam Tuner is capable of superb reception...

but only if it is receiving a good quality transmission signal.

As the signal is so important for good reception we have created a
quick reference guide to setting up the aerials.

You are recommended to fit an FM and an AM Aerial.

FM AERIAL

Required to receive VHF radio signals.

FOR BEST FM RADIO RECEPTION

A roof mounted aerial is essential. For your own safety it is
recommend that a rooftop aerial is fitted by an experienced
contractorYou can find these in your local telephone directory or
Yellow Pages. Your contractor will tune and direct the aerial to your
nearest FM transmitter In blocks of flats, an aerial system may
already be installed and connected to wall mounted sockets
marked FM orVHF (notTV).

Alternatively, you may decide to install an aerial yourself Use one
designed for‘Band 2' (VFHF/FM) reception.These are available from
electrical accessories shops (e.g.TANDY).This should be put
outside the building, mounted as high up as possible. Aerials can be
fitted in lofts, but metal foil cladding used for heat insulation may
make this option useless.
As a rough guide use the following table to indicate the type of
aerial you may require.

Up to 40 miles (65 km) from a transmitter

Over 60 miles (100 km) from a transmitter 6 or 8 element aerial

See ‘Radio Transmitting Stations’, mentioned later for details of how
to find the location of your nearest transmission station.

Alternatively a circular‘Omni-directional’ aerial can be used, though
this will not usually provide as much signal as the multi-element
types of aerial mentioned above.

The coaxial cable from the aerial should be fitted with a coaxial
plug and used with the adaptor provided. Plug it into the socket

Q in the back of your Arcam Alpha 7/8 tuner

FOR GOOD FM RADIO RECEPTION
If you will be using your tuner within a few miles of a major radio
transmitter theT shaped wire aerial (dipole design) supplied should
give a good reception. Use the aerial and the coaxial plug adaptor
provided, to connect it to the socket Mount the aerial as high
as possible on a wall.Try each usable wall of the room to see
which position gives best reception,The usual configuration is to
use the aerial in aTshape, with the two ends (elements) forming
the top cros-spiece. Use tacks or tape to hold the aerial in aT
shape.The tacks should not come into contact with the internal
aerial wire.

VERTICALLY POLARISED SIGNALS
Some signals from radio transmitter are ‘vertically polarised', (see
‘Radio Transmitting Stations’mentioned later for details) in which
case the aerial needs to be located with its elements vertical.
Most, but not all signals have a ‘horizontal component’, if all the
stations you wish to receive have this, then aligning the aerial
elements horizontally may help to avoid interference. It is best to
try several positions.

3 element aerial

AM AERIAL

Required for Medium Wave (MW) and Long Wave (LiVV) radio
radio signals.

There is an AM loop aerial supplied. Connect one end of the loop
aerial into socket and the other end into © . It does not
matter which of the wires go to which socket Rotate the aerial to
see which position gives the best reception. Some interference of
the signal may be experienced near a fluorescent light tube or a
television. Each transmitting radio station may require the aerial to
be adjusted slightly. Even on the same frequency, the best aerial
orientation can vary with time.

In areas of weak reception or when the tuner is used inside a steel
framed building (such as a block of flats) you can use a long wire
approximately 3-5 metres long and mounted high up outside the
building. Connect the end of the wire to © as well as the loop
aerial supplied. Do not disconnect the loop aerial.

Radio signals are not transmitted in LW in the USA , Canada and
some European countries.
