Classik-K Product Description
Functional Description
Power Supply
The Classik-K power supply is based on a powerful, yet quiet transformer. You may
notice that the transformer and mains inlet are located in a slightly different position
compared with earlier versions of Classik – the reason for this is very simply to allow
for optimum use of space inside the product as the additional functionality requires
more space.
There are two separate power supplies within the Classik – the auxiliary supply and
the main supply:
Auxiliary Supply
– this is on at all times, as long as the Classik is switched on, even
if the unit is in standby. It su5V to the display & control circuits at all times,
which allows constant monitoring for incoming user commands via remote or front
panel to bring the Classik out of standby. When the Classik is out of standby (normal
operating mode) the auxiliary supply also pr5V to the CD engine board and
switches the main power relay to activate the Main Power Supply.
Main Power Supply
– this is only active when the Classik is in normal operating
mode. It pr35V to the power amplifier section and su15V and +10V
to the audio preamplifier and other analogue low-voltage circuits.
Fuse
– the fuse is now located internally, beside the mains-inlet. If it blows, try
replacing it (with correct value & rating). In our experience, however, fuses in Linn
products seldom blow except where a problem exists either inside or external to the
product, which may require to be traced and eradicated before fuse replacement has
any permanent effect.
Control & Display
The control board provides the user interface to the Classik via the remote sensor &
front panel control keys.
Logic level data lines include power fail detection, interface, I
2
C interrupt from the
Tuner RC5 control and display data from the CD engine and other Classik-K’s (via
the internal multiroom facility).
CD-Player
The CD control has its own processor, which receives commands from the control
board’s keypad and remote control sensor via the RC5 connection. The display data
is written directly from this processor to the display driver IC’s on the front panel.
The CD board carries out tracking, focus & spindle servo control, diode detection, D-
A Conversion and CD loading operations.
CD-Digital Output (new feature)
The CD-Digital Output is a simple digital feed, which comes directly from the CD
board, i.e. by-passing the internal D-A converter stage. This can be connected to the
‘record’ input of a digital recording device such as a CD-R, Minidisc, DAT etc to allow
digital recording. The connection is Optical, in order to allow connection to the vast
majority of digital recording devices. Any recording devices that do not have an
optical connector cannot be used for digital recording from the Classik-K.
Please note, the Classik-K does not contain an A-D converter, so cannot provide a
digital output for any other sources (such as Tuner or any external sources)
