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 Input connections:
Input sockets are RCA Phono Sockets and should be connected according to the
standard convention – Right Channel – Red; Left Channel – White or Black.
Connecting a Preamplifier:
Connect the Preamplifier Output to the INPUT IN Sockets (1) on the rear panel of the
Caspian Power Amplifier.
Chain Connecting Multiple Amplifiers:
If there are no extra ‘PRE OUT’ sockets available for connection to further power
amplifiers; connect the CHAIN OUT Sockets (2) on the rear panel of the first Caspian Power Amplifier to the
INPUT IN Sockets of the second unit, and so on. Several amplifiers can operate together in this way.
Bi-amping with the Caspian Integrated Amplifier:
Connect the PRE 1 or 2 OUT Sockets on the rear panel of the Caspian Integrated
Amplifier to the INPUT IN Sockets (1) of the Caspian Power Amplifier (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.

The right and left loudspeakers are connected to the amplifier via the rear panel binding posts (3) and (4)
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”).
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.
