6. 1 Linn Products Limited All rights reserved 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 supplies 5V to the display amp 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 provides 5V 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 provides 35V to the power amplifier section and supplies 15V 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 amp rating In our experience however fuses

The Receiver circuit in the other Classik K then reconverts the balanced audio to Line level which its amplifier circuit can process as normal NOTE Audio distribution is from Main room to Secondary rooms only Distribution from Secondary room to Secondary room is not possible nor is it possible to distribute from Secondary room to Main room This is the case for Knekt and Connect Multiroom Display A Classik K in a Secondary room which is accessing the Main room Classik K also receives the display information from the Main room unit so that any useful aspect of its display can be seen on the Secondary room display such as CD track amp time information tuner frequencies source selection etc In this respect the user will find control of the Main room Classik from a Secondary room just as easy as controlling the Classik in that room In fact the only indication that they are controlling the Main room Classik and not the one that is facing them is an LED on the display which will light up showing the word MAIN Multiroom Control In a Secondary room the simple act of pressing the Listen button on the handset or Source amp buttons on the front panel together allows you to alternate between the Main room or the room that you are in Page 8 Copyright 2001 Linn Products Limited All rights reserved Classik K Product Description Control of the Main room system from a Secondary room is done very simply as long a

10. erved Classik K Product Description Introduction About the Classik K The Classik K is an independent CD Tuner Multiroom amplifier which replaces the Classik T in our product range Since the Classik T Multiroom functions Connect and Knekt have been added as well as a CD digital output which allows recording of the Classik s CD player to a digital recording device such as Minidisk The Connect function provides a very simple but extremely effective DIY plug and play multiroom system whereby the output of one Classik K can be distributed to another one two three or four Classik K s in other rooms in the house and controlled from those rooms via simple plug in connections and cable runs The term Connect in the sense of multiroom applies exclusively to a Classik only system The Knekt function allows the Classik K to be incorporated into a full Linn Knekt system This is not a customer DIY option and must be carried out by a trained Knekt installer As the audio distribution in both cases is carried via balanced audio cables there is no discernable noise or loss of quality at its destination even over very long cable runs Cabling information can also be found later in this document Classik K in multiroom systems is covered in more detail later in this document Important Information e The Mains out socket which was included on the Classik T has been removed as a response to customer feedbac
