What is stereo?




There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

Linn Asak MC


The Linn Asak Moving Coil Cartridge
Extending the philosophy of the turntable and arm to the design of the cartridge, it is obvious that the stylus, cantilever, and coils ahould be allowed to move freely in response to the information in the groove of the record. The rest of the cartridge should remain in a fixed position centered over the groove. This seemingly simple task is complicated by the fact that very high levels of energy are generated at the stylus tip. That energy travels up the cantilever and into the cartridge. The only way to prevent that energy from moving the cartridge body and the magnet assembly is to make the mass of the body and magnet very, very large. The most practical way to accomplish this is to use the mass of the arm and even the mass of the turntable. This is done by coupling the cartridge body very firmly to the arm.
The most significant differences between the Linn Asak and other moving-coil cartridges concern Linn's  efforts in designing a body that is rigid enough and strong enough to accomplish the task of coupling the cartridge to the arm. In order to provide  the strength necessary, the body is considerably wider than most. The unique recessed cartridge mounting holes allow the mounting screws slipping away from the body and / or the screwdriver accidentally slipping off the screws and damaging the stylus. In addition, to prevent any movement of the magnet assembly, great care has been taken to couple it very firmly to the body.

Arm Selection
If an arm other than the LV-II is to be used with the Asak, care should be taken to insure that it has a very rigid bearing assembly (knife edge or unipivots are generally not suitable), and that the headshell is wide enough to accept the 20 mm wide body of the cartridge.
