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.

If the plug becomes damaged or is not suitable for your socket outlet, it

should be cut off and an appropriate plug fitted in its place by a qualified

service personnel. The replacement plug should have the same fuse rating

as the original plug. The severed plug must be disposed of to avoid a

possible shock hazard and should never be inserted into a mains socket

elsewhere.

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

Please read the safety instructions and follow all guidance.

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.

Surface Heat

The top surface of the unit will get hot in operation. Do not

leave items on the top surface and avoid contact with the

top of the unit. A warning label is affixed to the top surface.

Set-Up

Connecting mains Power

Please refer to the front & rear panel view on Pages 6 & 7. The moulded IEC

connector of 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

respective speakers 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.
