C A U T I O N S K a n d y Integrated Amplifier

A C M A I I N S S U P P L Y

Your Kandy 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 this label as below:

230V Products ………………………………….Voltage Range: 220V – 240V

115V Products ………………………………….Voltage Range: 100V – 120V

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 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 unused for some time, unplug it from the mains supply.

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 (15) on the rear of the unit first and then plugged into the mains supply. The Mains power switch (14) is on the rear panel of the Integrated 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.

S I I G N A L C O N N E C T I O N S

Signal Input connections:

There are six Inputs (5 – 10) on your Kandy Integrated Amplifier in addition to the Tape

Input (3). Except for the PHONO input (5), 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 a MM phono cartridge. (This input can be set by Roksan or Roksan appointed service centres to Line Level input if so required.)

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 labeled 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 Connections:

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.

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 right and left loudspeakers are connected to the amplifier via the rear panel binding posts (11) and (12) 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.




Page 5 of 11


Version 3.3

ENGLISH

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-01S High Definition Loudspeaker Cable. Many speaker cables such as the ROKSAN HDC-01S are directional. Please observe this directionality. 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.

M u l l t t i i A m p i i n g T h e L o u d s p e a k e r s S e t t u

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 p 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.

For setup and connection details on Multi-Amping refer to the Kandy Power Amplifier Manual.

Note: Multi-Wiring connects the Woofer and the Tweeter directly to the output of the amplifier and is the first step towards Multi-Amping.

O P E R A T I O N K a n d y Integrated Amplifier

Please refer to the front and rear panel views on page 4 and the Remote Handset View on page 8.

S W I I T C H I I N G O N

The Mains power switch (14) 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 power supply.

When switched ON from the rear panel, your Kandy Integrated Amplifier will go to STANDBY and the MODE indicator light (4) will glow GREEN. The amplifier is now ready for use.

You can activate your Kandy Integrated Amplifier in two ways:

1

2

Press the MODE button (1) on the front panel once.

Press the POWER button (2) on the remote handset once.

The Kandy Integrated will ‘wake up’ and the MODE indicator light (4) will glow RED. The amplifier will automatically check its input/output status and select and connect to the CD input and the CD input indicator light

(5) will glow RED. After a brief moment the output relays will click on and the amplifier goes into normal operation mode.

U S I I N G T H E C O N T R O L S

MODE CONTROL

The MODE button on the Front Panel (1) has the following functions:

• It activates the amplifier from Standby. NOTE: From the Remote Handset, only the POWER Button (2) can put the amplifier in and out of standby.

• Pressing the MODE button once with the amplifier activated will mute/lower the volume level by 20dB. The

MODE indicator light will glow AMBER. The amplifier remains fully functional in this mode. Another single press unmutes the amplifier and the MODE indicator light will revert to RED.

• Full mute is only accessed from the Remote Handset by pressing the MUTE button (4). The MODE indicator light (4) will flash RED and the sound will be fully muted. Another single press unmutes the amplifier and the

MODE indicator light will revert to RED.

• With the amplifier activated, a sustained press on the MODE button reverts the amplifier to Standby, all the input indicator lights will be extinguished and the MODE indicator light will glow GREEN.

NOTE: When you bring the Kandy out of STANDBY having switched it ON at the Mains, the input selector will default to CD (as described previously).

When, however, the Kandy has been put into Standby from the MODE (Front panel) or the POWER (Remote handset) button, bringing it out of Standby will restore previously selected input and tape values.

INPUT SELECTOR BUTTONS

The INPUT Selector Buttons (2, Back) and (3, Forward) march through the inputs one click at a time. They connect each signal source to the amplifier by marching through the Inputs with the exception of TAPE. Pressing the Forward Button (3) repeatedly will select inputs in this sequence:

CD - TUNER - VIDEO - LINE1 - LINE2 - PHONO - CD - …

Pressing the Backward Button (2) repeatedly reverses the sequence.

Whenever an input is selected the appropriate indicator lights up.

VOLUME CONTROL

The VOLUME Control is a precision device. It follows a logarithmic 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.

TAPE MONITOR

When you select an INPUT, the selected source is connected to the amplifier and to the Tape Output Sockets (4) of the Kandy thus enabling you to record off of the selected INPUT.




Page 7 of 11


Version 3.3

ENGLISH

The Tape Monitor is an override. Pressing the TAPE Button (12) connects the output of your tape deck to the

Kandy, overriding the selected input. However, the selected input is left connected to the recording input of your tape deck. If you have a suitable tape deck, this facility enables you to record a programme whilst monitoring its playback.

When the TAPE Button is depressed, the TAPE Indicator light (11) glows and the selected source Indicator remains illuminated.

The input selector remains functional when the Tape Monitor is ON, allowing a range of sources to be recorded.

Pressing the TAPE Button toggles between Tape Monitor ON and OFF.

R E M O T E H A N D S E T

The Kandy Integrated Amplifier MKIII Remote Handset uses two AA size 1.5V batteries. These are housed in the battery compartment on the underside of the handset.

Carefully remove the battery compartment cover and insert the supplied batteries in place observing polarity.

Replace the cover. The handset is now ready for use.

The front panel controls of the Kandy Integrated Amplifier are replicated on the remote handset.

• When you first power up from the Mains Switch on the rear panel, the amplifier goes into Standby and the

MODE Indicator glows GREEN.

• During Standby, the power stage of the amplifier is shut down to reduce power consumption and heat.

• In normal operation when an external fault such as a short circuit on the loudspeaker leads is detected, the amplifier will go into standby and the speaker output and AC power relays will disconnect and the MODE indicator light will glow GREEN. Unless the fault is rectified the amplifier can not be brought out of standby.

• If the amplifier output current exceeds its safe operating range (very low loudspeaker impedance and high volume level) the Kandy integrated will revert to Standby. If subsequently the volume is lowered or the loudspeakers changed, the amplifier can be brought out of standby to resume normal operation.
