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.

ADC LMF's Tonearms

 The ADC LMF  Carbon Fibre Low Mass Tonearms
The LMF-1 has an integrated head for lowest mass.
The LMF-2 has a removable head.
 We chose carbon fibre because of its low mass to high tensile strength ratio. Then we were able to further lower the mass by abandoning the traditional tubular shape and engineering the fully tapered profile. Carbon fibre has yet another asset which anyone with a serious love of quality music reproduction will love. The inherent properties of the material are antiresonant.
The combination of a fine cartridge and the LMF low mass tonearm will not interact with typical building resonant frequencies or with typical record warp frequencies. The LMF tonearms are styled in mat-black to blend into the design of any high quality turntable.
 The cueing is viscous damped in both directions for optimum stylus care. Tracking forces are calibrated in 1/10 th gram increments with a precision click-stop dial. Anti-skate adjustments are infinitely variable to 2 grams.
The LMF tonearms each come with three cylindrical counterweights to enable you to achieve zero balance with minimum effective tonearms mass, regardless of the weight of your favorite cartridge even up to 11 grams. 
 The LMF-2 has a removable head.
This allows the audiophile whose tastes require alternative phono cartridges to make premounted changes in seconds, both permit the use of the highest compliance cartridges with lowest tracking forces.
 The pivot system uses stainless steel instrument bearings, which are hand picked and perfectly matched to both the outer and inner races for virtually frictionless movement without the vulnerability to damage found with typical "knife-edge" bearing sytems.
