Circuit Switch
A Linn Knekt product - A switching box. Used in a Knekt system to automatically switch devices on, off etc
(an example might be switching on amps, TV etc ) when the RCU is powered up. Can also be used to make
and break connections (e.g. to switch speakers on and off)
Cirkus
Bearing & sub-chassis upgrade for the LP12. Already fitted to LP12s > s/no 90581 (Apr 93) , but can be
retro-fitted to older models as a sound quality improvement.
Classik
Linn Independent Amplifier – originally introduced 1998. This version (i.e. the first version) was an integrated
amplifier, containing a CD player. Other sources can be connected via inputs at rear. Superseded by Classik
with Tuner (known as Classik-T) and later by Multiroom version (Classik-K)
Classik-K
Version of Classik that superseded the Classik-T – contains all the functionality of the Classik-T with added
multi-room capability. Can be easily interconnected with up to four other Classiks to form a simple DIY ‘plug-
and-play’ multi-room system or can be incorporated into a Linn Knekt system.
Classik-T
Version of Classik that superseded the first incarnation. Contained all the functionality of the original Classik
with the addition of an integrated radio tuner.
Control Board
The circuit board in a product which is the user’s interface with the product, i.e. contains the control buttons,
display (if applicable) etc. Usually it is the front panel board.
Crossover
(Universal term) - The device which separates the music signal coming from the Power amp output
according to frequency: either into Bass and Treble or Bass, Mid and Treble, depending on the speakers
used. Can be passive or active (see Aktiv above). Passive crossovers are the basic version, using a very
simple circuit to divide the signal - not powered up - these are usually (but not always) located inside the
speaker cabinet.
Linn Aktiv crossovers were originally located in a box by themselves but now are fitted inside Linn Power
amps. Quite simply Active crossovers do the same job as passive but better and in a controlled manner.
Active crossovers require to be powered up.
Cross-talk
A term used generally in electronics, which mean that a signal within a part of a circuit is somehow crossing
to another part of the circuit or another device that it should not be. In Hi-Fi, it is most commonly used to
describe a situation where music from one input is crossing to another input or music from one channel is
crossing to another.
