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

SWITCHING ON  
The Mains power switch (6) is located on the rear panel of the FM Tuner. This switch should be left ON for normal  
operation. If unattended for a long period, the Mains power should be switched OFF and the lead disconnected  
from the power supply.

the station and indicate the signal strength.  
You may now store this station in a preset (See Page 7)  
Spin the TUNE knob again to repeat the procedure.  
To stop an automatic scan  
Slightly move the TUNE knob in the direction opposite to the scan i.e. if the tuner is scanning up the band an  
anticlockwise rotation will halt the scan.  
The autoscan may also be stopped by clicking the CHANNEL knob one position to the right or left.  
MANUAL TUNING

SIGNAL DISPLAY  
For an FM station to provide good fidelity its signal must be strong enough to trigger the tuner’s tuning and noise  
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.  
STEREO OR MONO?  
Stereo: During stereo reception the Stereo Indicator lights green.  
Mono: During mono reception there is no indication.  
Forced Mono: If stereo reception is noisy or distorted, you may wish to switch the tuner to mono.  
Press the MODE button briefly to force the tuner into mono.  
Press MODE again to restore normal operation.  
During forced mono the Stereo Indicator lights red.  
STORING AND RECALLING A PRESET CHANNEL  
Tune in the desired station.  
Select mono or stereo.  
Press the STORE button. The Channel Indicator will flash.  
Rotate the CHANNEL knob clockwise to select a higher channel and anticlockwise for a lower one. To leave the  
channel unaltered - do nothing.  
Press STORE again.  
The station is now stored in the channel memory. You may store up to 50 channels in this way.  
You can store the same station in mono and stereo by allocating each setting a different channel number.  
To recall a preset channel:  
Rotate the CHANNEL knob to select the channel.  
CHANGING A PRESET CHANNEL  
Select a preset channel using the CHANNEL knob.  
Press STORE. The existing channel number will flash.

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.
