CAUTIONS
C a s p i a n FM Tuner
AC MAINS SUPPLY
Your Caspian FM Tuner is set to operate from a fixed supply voltage which is marked on a label next to the
mains input plug. Before connecting the mains lead please check that your mains supply corresponds to this
label as below:
230V Products ………………………………….Voltage Range: 220V – 240V
115V Products ………………………………….Voltage Range: 100V – 120V
100V Products ………………………………….Voltage Range: 90V – 110V
The mains lead supplied with this product has an IEC mains socket which plugs into the IEC connector on the
unit’s rear panel. The other end is normally attached to the appropriate mains plug for your country. In the UK
this is the standard UK13A plug.
This plug should ordinarily not be removed from the lead. If you do remove it, please dispose of it safely so that it
cannot be plugged into a mains socket whilst in a potentially dangerous condition. We suggest that you obtain
from your dealer a complete replacement lead.
Should you move to another area where either the mains voltage or the mains plugs are different from those as
supplied with your FM Tuner, please contact the appointed ROKSAN distributor for assistance.
Please observe correct mains polarity at all times.
The FM Tuner mains fuses are located on the rear panel next to the IEC mains connector. They must only be
replaced by the fuse of the type and rating as described on the fuse rating label on the rear panel of the unit.
If the equipment is likely to be unused for some time, unplug it from the mains supply.

SETUP
C a s p i a n FM Tuner
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 75Ω Coaxial Aerial Socket.
FM aerials in the UK use 75Ω screened coaxial cable and this is the prefered cable.
If you live in an area where 300Ω 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 75Ω (for
aerial connection). The HDC-01D could be terminated to suit the aerial socket/connections.

limiting circuits. The tuner must also lock precisely on to the centre of the broadcast signal.
The Signal Display Unit on your Caspian tuner displays both Signal Strength and Centre Tuning.
No Signal
Very Weak & Noisy
Strong Signal
Accurately Tuned
Fairly Strong Signal
Tuned Off Centre
When manually tuning a station, the centre figure of the above display is the one to aim for.

AUTO STORE FUNCTION
Your Caspian FM Tuner has the facility to automatically tune in and store up to 25 stations.
To activate the Auto Store Function:
Switch the tuner OFF via the rear panel switch.
Hold down the STORE button and switch the tuner on.
Release the STORE button.
Your Caspian tuner will scan the band, increasing in frequency. As a station is detected and stored, the channel
indicator will flash to register the information.
When 25 stations have been memorised the tuner will enter STANDBY. If less than 25 stations are detected the
tuner will memorise those and enter STANDBY.
During auto scan the station with the lowest frequency is stored in channel 50, the next lowest in 49 and so on.
Information in the memory between channels 50-26 will be overwritten. Channels 1-25 are unaffected.
Bring the tuner out of STANDBY.
The tuner display will default to Channel1.
Turn the CHANNEL knob one position to the left. This will select Channel 50 which is the first station memorised
by the auto-store routine.
Re-arrange the channels as required. (See Page 7.)
MUTE THRESHOLD LEVEL
Your tuner has been set up to ignore signals below 20dB µV when auto tuning or auto storing. This corresponds
to two dots on the Signal Indicator.
Distant or low level signals should be tuned and stored manually. (See Pages 7&8).
MEMORY STORAGE AND PRESET RECALL
Information in the Caspian tuner is held in non-volatile memory. You can leave the tuner switched off at the mains
indefinitely without losing any information.
Use channels 1-25 to store favourite stations as these are unaffected when the tuner is in auto-store mode.
When scanning, if a station is detected that is already preset in the channel memory, that number will indicate. If
the same station is held in more than one preset, the indicator will default to the lowest number.
