CAUTIONS
C a s p i a n Mono Power Amplifier
AC MAINS SUPPLY
Your Caspian Power 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 Power Amplifier, please contact the appointed ROKSAN distributor for assistance.
Please observe correct mains polarity at all times.
The Power 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.

•
•
•
•
Re-orient or re-locate the receiving antenna

SETUP
C a s p i a n Mono Power 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 (5) on the rear of the unit first and then plugged into the mains supply. The Mains power
switch (8) is on the rear panel of the Power 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:
Input socket is high quality gold plated RCA Phono Socket and should be connected
to corresponding preamplifier output.
Connecting a Preamplifier:
Connect the Preamplifier Output to the INPUT SIGNAL Sockets (1) on the rear panel
of the Caspian Mono Power Amplifier.
Chain Connecting Multiple Amplifiers:
If the preamplifier used does not have sufficient number of pre outs, connect the
CHAIN OUT Socket (2) on the rear panel of the first Caspian Power Amplifier to the INPUT SIGNAL Sockets of
the second unit, and so on. Several amplifiers can operate together in this way.
Bi-amplifiying with the Caspian Dual Mono Preamplifier:
Connect the PRE 1 OUT Sockets on the rear panel of the Caspian PreaAmplifier to
the INPUT SIGNAL Sockets (1) of the first pair of Caspian Mono Amplifiers and the PRE 2 OUT Sockets to the
INPUT SIGNAL Sockets (1) of the second pair of Caspian Mono Amplifiers (See diagram on Page 6).
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 loudspeakers are connected to the amplifier via the rear panel binding posts (3) and/or (4). 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”).
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
amplifiers are 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 MULTI-AMPING
LF
HF
Multi-Amping The Loudspeakers
Operation
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 hence 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 Mono Power Amplifier
Please refer to the front and rear panel views on page 4.
SWITCHING ON
The Mains power switch (8) 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 Mains socket on the wall.
When switched ON from the rear panel, after running a quick self-test your Caspian Mono Power Amplifier enters
operational mode. The MODE Indicator Light (1) will glow RED.

AUTOMATIC OPERATION
The Caspian Mono Power Amplifier auto senses the audio signal and remains operational while there is a signal
present with the MODE indicator RED. It will prepare itself for standby after approximately 2 minutes of no signal
and the MODE indicator will change colour to ORANGE. If there is still no signal for about 20 minutes, it will go
into stand by and the MODE indicator will glow GREEN. As soon as a signal is detected, it will come out of
standby and revert to operational mode with the MODE indicator will glow RED again.
With this facility the Caspian Mono Power Amplifier is ideal for Multi-amping, high-end A/V installations or in any
application, (e.g. multi-room), where the amplifier is required to switch ON and OFF with the rest of the system
with no loss of functionality.
KNOW YOUR CASPIAN
•
When you first power up from the Mains Switch on the rear panel, the amplifier runs a quick self-test and
then enters operational mode with the Indicator glowing RED.
•
•
During Standby, the power consumption of the amplifier is reduced thus reducing generated heat.
If the amplifier detects a fault, such as power rail failure, over current etc. it will go into protection mode and
the indicator will flash. You can only bring the amplifier out of this mode when the fault is cured by simply
switching it off and on.
•
If the amplifier overheats through overload or lack of ventilation, it will also enter protection mode. When it
has cooled down you will be able to bring it out of this mode.
In the unlikely event of an internal fault such as a power supply fault, the amplifier will go to permanent Standby.
TROUBLESHOOTING
C a s p i a n Mono Power Amplifier
If you suspect that your ROKSAN Caspian Mono Power Amplifier is not operating properly, you should check all
the connections carefully. Pay particular attention to speaker phasing and signal connections. Phono plugs
should be fully inserted- a frequent cause of problems is that Phono plug surrounds do not make proper contact.
Below are some commonly encountered problems with suggestions for possible cure. The list is not exhaustive:
If you have any unresolved problems, please consult your appointed ROKSAN dealer or distributor.
SYMPTOM
LIKELY CAUSE
SUGGESTED REMEDY

by mode. Bad speaker connections
rear panel
(Indicator Light RED) No input signal.
Missing or bad input signal connection
Check source is connected and
playing.
Check all input connections
Over heating
Allow amplifier to cool, increase
ventillation or use at lower volume
