AC MAINS SUPPLY
Your Caspian Integrated Amplifier 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 Integrated Amplifier, please contact the appointed ROKSAN distributor for assistance.
Please observe correct mains polarity at all times.
The Integrated Amplifier mains fuses are located on the rear panel next to the IEC mains connector. These must
only be replaced by the fuse 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 Integrated Amplifier
CONNECTING MAINS POWER
Please refer to rear panel view on Page 4. The moulded IEC connector of the supplied mains lead should be
plugged into the socket (13) on the rear of the unit first and then plugged into the mains supply. The Mains power
switch (16) is on the rear panel of the Integrated Amplifier. 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
Signal Input connections:
There are five Inputs (1 – 5) on your Caspian Integrated Amplifier in addition to the
Tape Input (6). All these inputs are line level inputs and will accept virtually all currently available source
components.
All the inputs use RCA Phono Connectors and should be connected according to the standard convention –
Right Channel – Red; Left Channel – Black or White.
Also in accordance with standard practice, the Upper row of Phono Sockets carries the Left Channel and the
Lower carries the Right Channel.
The Input Sockets are labelled with their legends upside down as well as the normal way round to assist you
should you be connecting an input from a position in front of and above the amplifier.
Phono Input Connections:
As your Caspian Integrated Amplifier is a line level unit you cannot connect a phono
cartridge directly to it but will need a dedicated phono preamplifier. The ROKSAN range of Caspian Phono
Amplifiers accept conventional moving coil and moving magnet cartridges and have custom equalisation for the
outstanding ROKSAN Shiraz cartridge. For a demonstration of ROKSAN state of the art turntable reproduction
contact your authorised retailer.
IMPORTANT NOTE: For optimum performance it is recommended to use high quality inter-connect cables such
as ROKSAN HDC-02A high definition analogue Cable.
LOUDSPEAKER CONNECTIONS
The right and left loudspeakers are connected to the amplifier via the rear panel binding posts (11) and (12)
respectively. There are two basic types of cable –
•
•
Figure 8 cable has two insulated conductors which lie parallel, either side by side, or spaced by insulation.
Overall sheathed cable has both conductors insulated and enclosed in an overall plastic sheath.
Carefully remove any overal sheath or split the figure 8 cable to a depth of about 75mm (3”).

Page 5
ENGLISH
Carefully strip the insulation on each wire to a depth of about 12mm (1/2”) exposing the
bare core. If the conductor is stranded, twist the strands together on each conductor.
Unscrew the binding post. There is a cross-hole about 5mm from the panel end of the
binding post. Insert the bared conductor through the hole and tighten the binding post
securely making sure that there are no loose strands or bare ends protruding through
the post.
Carefully observe polarity ensuring that the RED (+) speaker terminal is connected to
the RED (+) amplifier terminal and the BLACK (-) speaker terminal to the BLACK (-)
amplifier terminal.
When both left and right channels are connected to their respective speakers the
amplifier is ready for use.
IMPORTANT NOTE: For optimum performance it is recommended to use high quality cables such as ROKSAN
HDC-02S high definition Loudspeaker Cable. Many speaker cables such as the ROKSAN HDC-02S are
directional. Please observe this directionality. DO NOT use speaker cable with conductor size less than 16 AWG
(1.6mm Diameter). The Binding posts accept conductor sizes up to 12 AWG.
MULTI-WIRING AND MULTII-AMPING
Multi-Amping The Loudspeakers
If the Loudspeakers utilise more than one drive unit with individual input terminals, for example a Tweeter and a
Woofer, then the loudspeaker performance will benefit from Bi-Amping. Dedicating one amplifier to the Tweeter
and another to the Woofer isolates them from each other reducing distortion and increasing reserved power.
Speakers work far better with most amplifiers when Multi-Amped than using one yet more powerful amplifier.
Note: Bi-Wiring reduces the impedance seen by the Woofer and the Tweeter and is a first step towards Bi-
Amping.

OPERATION
C a s p i a n Integrated Amplifier
Please refer to the front and rear panel views on page 4.
SWITCHING ON
The Mains power switch (16) is located on the rear panel of the amplifier. 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.
When switched ON from the rear panel your Caspian Integrated Amplifier runs a self-test and the indicator lights
on the front panel pulse twice. The amplifier then reverts to STANDBY and the MODE indicator light (3) will glow
GREEN. The amplifier is now ready for use.
You can activate your Caspian Integrated Amplifier in two ways:
1
2
Press the MODE button (2) once.
Rotate the INPUT selector (1) in either direction by one step.
NOTE: The remote handset will activate the amplifier in the same manner.
The Caspian will ‘wake up’ and the MODE indicator light (3) will glow RED. The amplifier will automatically select
the CD input and the CD input indicator light (4) will glow.
USING THE CONTROLS
MODE CONTROL
The MODE button has the following functions:
•
•
It activates the amplifier from Standby.
Pressing the MODE button once with the amplifier activated will mute the volume level by 20dB. The
MODE indicator light will glow ORANGE. The amplifier remains fully functional in this mode. Another
single press unmutes the amplifier and the MODE indicator light will revert to RED.
With the amplifier activated, a sustained press on the MODE button reverts the amplifier to Standby, all
the input indicator lights will be extinguished and the MODE indicator light will glow GREEN.
•
NOTE: When you bring the Caspian out of STANDBY having switched it ON at the Mains, the input selector will
default to CD (as described previously).
When, however, the Caspian has been put into Standby from the MODE button, bringing it out of
Standby will restore previously selected input, tape and mute values. Bringing the Caspian out of
Standby by moving the INPUT Selector one step in either direction also leaves these amplifier settings
unaffected.
INPUT SELECTOR SWITCH
The INPUT Selector is an endless rotary switch that moves round one click at a time. It connects each signal
source to the amplifier by rotating through the Inputs with the exception of TAPE. Rotating the Selector
continuously clockwise will select inputs in this sequence:
CD – TUNER – VIDEO – LINE1 – LINE2 – CD - …
Rotating the Selector anti-clockwise reverses the sequence.
Whenever an input is selected the appropriate indicator light will glow.
VOLUME CONTROL
The VOLUME Control is a precision device. It follows a logarithmic law so that its response approximates that of
the human ear. There is an illuminated indicator on the volume control to clearly show the appropriate volume
setting.
TAPE MONITOR
When you select an input source, the INPUT Selector connects the selected source to the amplifier and connects
this source to the Tape Output Sockets of the Caspian thus enabling you to record.
The Tape Monitor is an override. Pressing the TAPE Button (10) connects the output of your tape deck to the
Caspian, overriding the selected input. However, the selected input is left connected to the recording input of
your tape deck. If you have a suitable tape deck, this facility enables you to record a programme whilst
monitoring its playback.

ENGLISH
When the TAPE Button is depressed, the TAPE Indicator light glows and the selected source Indicator remains
illuminated.
The input selector remains functional when the Tape Monitor is ON, allowing a range of sources to be recorded.
Pressing the TAPE Button, toggles between Tape Monitor ON and OFF.
REMOTE HANDSET
The Caspian System Remote Handset uses two AAA size 1.5V batteries. These are housed in the battery
compartment on the underside of the handset.
Carefully remove the battery compartment cover and insert the supplied batteries in place observing polarity.
Replace the cover. The handset is now ready for use.
The front panel controls of the Caspian Integrated Amplifier are replicated on the remote handset.

KNOW YOUR CASPIAN
•
When you first power up from the Mains Switch on the rear panel, the amplifier runs a self-test during
which all the Indicators pulse twice. When the self-test is complete the amplifier goes into Standby and the
MODE Indicator glows GREEN.
•
•
During Standby, the power stage of the amplifier shuts down to reduce power consumption and heat.
If the amplifier overheats through overload or lack of ventilation, the Caspian will revert to Standby until it
has cooled down. If it subsequently overheats the amplifier will revert to Standby and stays in Standby.
You will then have to wait until the amplifier cools down fully and will have to bring it out of Standby
manually.
In the unlikely event of an internal fault such as a power supply failure, the MODE Indicator light will flash
GREEN and the amplifier will shut down. The amplifier will then run a self-test. If all is well, the amplifier will
revert to Standby. If the fault persists, the Indicator light will continue to flash.
