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 XLM Mk II



The XML MkII Improved shares many of the virtues of the XLM MkIII Improved. Including excellent tracking ability and channel separation, high definition of musical passages and low record wear, plus the revolutionary Omni-Pivot System. The XLM MkII Improved also features a Diasa stone; a highly polished elliptical diamond tip fused to a sapphire base. Low effective tip mass is achieved by mounting the Diasa stone to a non-tapered hollow tube cantilever. The XLM MkII … a sound investment.
