CONNECTING MAINS POWER
Please refer to the rear panel view on page 4.
The moulded IEC connector of the supplied mains lead should be plugged into the socket (5) on the rear of the
unit first and then plugged into the mains supply. The Mains power switch (6) is on the rear panel of the FM
Tuner. This switch is normally left on. If the unit is likely to be unattended for a long period, switch it off and
unplug the mains lead from the wall.
SIGNAL CONNECTIONS
AUDIO OUTPUT:
The Audio Output (2) uses RCA Phono sockets and should be connected to the
TUNER or LINE input of your Preamplifier, Inegrated Amplifier or DSP.
The connection is: Right Channel – Red or
R ; Left Channel – White, Black or L .
AERIAL INPUT:
Your Caspian FM Tuner ia provided with a standard FM 75 Ω Coaxial Aerial Socket.
FM aerials in the UK use 75 Ω screened coaxial cable and this is the prefered cable.
If you live in an area where 300
Ω
aerials and balanced feeder cables are used (as in
some parts of the USA) you will need to use a ‘balun’ transformer to get the best
performance from your Caspian tuner. Your ROKSAN dealer will be happy to advise
you.
It is important that you have an adequate multi-element FM aerial installed outdoors
(or loft mounted) by a professional. The sensitivity (and cost) of the aerial will depend
on the height of your house, how far it is from your favourite stations’ transmitters,
and the presence of obstacles such as tall buildings or trees.
If you live close to a transmitter you may be able to get by with an indoor aerial, but
reception could well be sporadic and noisy, particularly in stereo. Indoor aerials are
affected by people moving in their vicinity and are very susceptible to electrical
interference from thunderstorms, passing cars, washing machines, etc.
Quality levels between broadcast stations are variable. In addition to the quality of the
programme there are technical factors affecting reception such as multipath
reflections, the degree to which the transmitter is off beam to the aerial axis, and, of
course, its distance.
When you have an aerial installed, a good idea is to have a ‘shopping list’ of stations
so that your installer can optimise the aerial installation to your requirements.
IMPORTANT NOTE: For optimum performance it is recommended to use high quality inter-connect cables such
as ROKSAN HDC-02A High Definition Analogue Cable and HDC-01D High Definition Digital Cable 75
Ω (for
aerial connection). The HDC-01D could be terminated to suit the aerial socket/connections.
