Cautions
AC Mains Supply
!
Your K3 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 the
label as below:
230V Products: Voltage Range 220V – 240V
115V Products: Voltage Range: 110V – 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 set of replacement leads.
Should you move to another area where either the mains voltage or the
mains plug 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 fuse is located on the rear panel next to the
IEC mains connector. This 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.
!
This product requires connection to earth (ground). The earth wire (in the
UK this is colour coded green/yellow) of the mains cable supplied with your
Integrated Amplifier must be connected to a suitable earthing point
established for this purpose by your electricity supply company. If you are in
any doubt, consult a qualified electrician.
If the equipment is likely to be unattended for some time, unplug it from the
mains supply. !

General Cautions
FCC Warning
!
This equipment may generate or use Radio Frequency energy. The user may
lose the right to operate this equipment if unauthorised modifications are
made.
Interference
!
Properly installed, this unit should not cause harmful interference to radio
communications. There is, however, no guarantee that such interference will
not occur in a specific installation. If interference arises (which you can
determine by switching the unit off and on) you could try to remedy matters
by using the following methods:
•Re-orient or re-locate the receiving antenna.
•Increase the distance between the K3 Integrated Amplifier and receiver.
•Connect the unit to a different mains circuit from that of the receiver.
•Consult your ROKSAN appointed dealer or an experienced Radio/TV
technician for help and advice. !
Location
!
Your K3 Integrated Amplifier should be located in a well ventilated area and
kept away from sources of heat, dust and humidity and from direct sunlight.!
The integrated Amplifier may be positioned either as a free standing unit or
along side another audio/video product. Never allow liquids or other
objects to fall into the unit.
This unit contains no user serviceable parts. DO NOT remove any panels or
attempt to service it yourself. Unauthorised servicing will void the warranty.

Set-Up
Connecting mains Power
!
Please refer to the front & rear panel view on Pages 5&6. The moulded IE
connector or the supplied mains lead should be plugged into socket (27)
on the rear of the unit first and then plugged into the mains supply.!
The mains power switch (15) is on the front under side of the Integrated
Amplifier. This switch can be left on; if however the amplifier is likely to be
unattended for a long period of time, switch it off and unplug the mains
lead from the wall.
Signal Connections
!
There are 6 Inputs (18 -24) on your K3 Integrated Amplifier. Except for
PHONO input (19) all other inputs are line level and will accept virtually all
currently available source components. The PHONO input is factory set for
Moving Magnet Cartridges to accommodate record players fitted with MM
phono cartridges. The AV input (22) is linked to the BYPASS input (18) and
switch to set BYPASS, then the AV input will be deactivated and the BYPASS
input will become activated. In this mode, the BYPASS input can be used to
a surround sound processor’s front L & R pre output for home theatre use.
The BYPASS input is directly connected to the power amp section and
bypasses the preamp. The volume is then controlled via the surround sound
processor and not the K3 Integrated. You could also use the integrated as a
power amp in this mode.
All the inputs use gold plated 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 row carries the Right Channel.!
The input sockets are labelled with their legends upside down as well as the
normal way up to assist you should you be connecting an input from a
position in front of and above the amplifier.

MC Input Connection
If you wish to use a Moving Coil Cartridge, an in-line MC step-up
transformer should be connected to the Phono Input. Alternatively a
dedicated Phono Stage can be connected to a line level input.!
(NOTE: if you wish to connect to the Phono input, it must be set for line level
signal. See above). For advice and demonstration of ROKSAN state of the
art turntable reproduction systems contact your authorised retailer.
!
Loudspeaker Connections
!
The right and left loudspeakers are connected to the amplifier via the rear
panel binding posts (25) and (26) 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 over all 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 12 mm (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 5 mm 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 the
irrespective speaker’s the amplifier is ready for use.

IMPORTANT NOTE: For optimum performance it is recommended to use
high quality inter-connect cable such as ROKSAN HDC-03A High Definition
Analogue Cable.
IMPORTANT NOTE: For optimum performance it is recommended to use
high quality cable such as ROKSAN HDC 03S High Definition Loudspeaker
Cable. Many speaker cables such as the ROKSAN HDC-03S are directional.
Please observe this characteristic. DO NOT use a speaker cable with
conductor size less than 16 AWG (1.6mm Diameter). The binding posts
accept conductor sizes up to 12 AWG.
!
Multi-amping Loudspeakers
!
If the system loudspeakers utilise more than one drive unit with individual
input terminals, for example a Tweeter and Woofer, then the loudspeakers
performance should benefit from bi-amping by use of the addition of a K3
Power Amplifier. 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 significantly better with most
amplifiers when multi-amped than using one, more powerful, amplifier.
For setup and connection details on multi-amping refer to the K3 Power
Amplifier Manual.
!
Multi-wiring Loudspeakers
NOTE: Multi-Wiring connects the Woofer and the Tweeter terminals directly
to the output terminals of the amplifier and is the first step towards Multi-
Amping.
