SETUP Kandy K2 BT Integrated Amplier
CONNECTING MAINS POWER
Please refer to the front & rear panel view on Page 3. The moulded IE connector or the supplied mains lead should be
plugged into socket (27) on the rear of the unit rst and then plugged into the mains supply.
The mains power switch (15) is on the front under side of the Integrated Amplier. This switch can be left on; if however
the amplier 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 Kandy Integrated Amplier. 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 accomodate record players tted 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 Kandy 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 amplier.
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 amplier 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 parellel, either side by side, or spaced by insulation.
• Over all sheathed cable has both conductors insulated and enclosed in an overall plastic heath.
Carefully remove any over all sheath or split the gure 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 connencted to
the RED(+) amplier terminal and the BLACK(-) speaker terminal to the BLACK(-) amplier terminal. When both left and
right channels are connected to the irrespective speaker’s the amplier 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 Denition Analogue Cable.
IMPORTANT NOTE: For optimum performance it is recommended to use high
quality cable such as ROKSAN HDC 03S High Denition 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 upto 12 AWG.

Multi-Amping The Loudspeakers
If the loudspeakers utilises more than one drive unit with individual input terminals, for example a Tweeter and Woofer,
then the loudspeakers performance should benet from Bi-Amping. Dedicating one amplier 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 ampliers when multi-amped than using one more powerful amplier.
For setup and connection details on Multi-Amping refer to the Kandy Power Amplier Manual.
Please refer to the front and rear panel views on Page 3.
SWITCHING ON
The mains power switch (15) is located on the front under side of the amplier.This switch can be left ON for normal
operation. If unattended for a long period of time (going on a short break, holidays etc.) the mains power should be
switched OFF and the power cord disconnected from the mains power input.
When swithched ON, THE K2 logo in the ‘mirror‘ display will glow red and your Kandy integrated amplier will be on
STANDBY with the MODE indicator (4) illuminated in GREEN. The amplier is now ready for use.
You can activate your Kandy Integrated Amplier in two ways:
• Press the MODE button (1) on the front panel once.
• Press the POWER button (3) on the remote handset once.
The Kandy Integrated will ‘wake up’, the MODE indicator illumination will change to RED, the CD input will be selected
and the CD input indicator (5) will illuminate RED. The amplier will then automatically check its input/output status and
after a brief moment when no problems are detected, the speaker output relays will click on and the amplier starts in
normal operation mode responding to all front panel buttons and the remote.
MULTI-WIRING THE LOUDSPEAKERS
NOTE: Multi-Wiring connects the Woofer and the Tweeter terminals directly to the output terminals of the amplier
and is the rst step towards Multi-Amping.

USING THE CONTROLS
MODE CONTROL
The MODE button on the Front Panel (1) has the following functions:
• It activates the amplier from Standby. NOTE: From the Remote Handset, only the POWER Button (3) can put
the amplier in and out of standby.
• Pressing the MODE button once with the amplier activated will mute/lower the volume level by 20dB. The
MODE indicator light will change to AMBER. The amplier remains fully functional in this mode. Another signal
press, un-mutes the amplier and the MODE indicator light will change to GREEN.
VOLUME CONTROL
The VOLUME control is a precision device. It follows algorithmic law so that its response approximates that of the human
ear. There is an indicator on the volume control to show the appropriate volume setting.
INPUT SELECTOR BUTTON
The INPUT Selector Buttons (2) and (3) shift through the inputs one click at at time. They connect each signal source to
the amplier by shifting through the Inputs. Pressing the Forward Button (3) repeatedly will select inputs in this sequence:
CD - AUX1 - AV - AUX2 - AUX3 - PHONO
Pressing the Backward Button (2) repeatedly reverses the sequence.
Whenever an input is selected the appropriate indicator light will illuminate.
NB: To select the Bluetooth input, press the Bluetooth on/off button (12). The Bluetooth on light will illuminate when
selected.
BLUETOOTH CONNECTION & PAIRING
Make sure your device’s Bluetooth is enabled and press the Bluetooth on/off button (12) located on the front panel of
the amplier. This will select the Bluetooth source and when your device has found the amplier, ‘ROKSAN K2 BT’ will
appear on your device. Next, connect to pair your device. You are now ready to stream music to the K2 BT from the
paired device. If your device is apt-X compatible and contains high resolution audio les, then these will be streamed in
the original high quality bit rate through the K2 BT.
KNOWING YOUR KANDY
When you rst power up from the Mains Switch (refer to diagram on page 3), the amplier goes into Standby and the
MODE indicator glows Green.
In order to reduce power consumption and heat, the power stage of the amplier is shut down when in STANDBY mode.
If the amplier output current exceeds its safe operating range (very low loudspeaker impedance and/or very high
volume level) the protective circuitry of the Kandy will take the amp into Standby mode. If subsequently lowered or the
loudspeakers changed, the amplier can be brought out of Standby to resume as normal.
NOTE: First time when you bring the Kandy out of STANDBY mode after switching it ON at the Mains, the input
selector will default to CD (as described previously.)
Subsequently, bringing the Kandy out of the standby from standby using the MODE or the POWER (Remote handset)
buttons, will restore the inputs that was selected before it was put into Standby.
