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.

Fairchild SM-1 Cartridge

Fairchild progres is typified in the new SM-1 Rotating Magnet Compatible Stereo/Monophonic cartridge.

The efforts of Fairchild's engineering staff, skilled as no other group in professional transducers, is culminated in a sleek, functionally designed cartridge.

The Fairchild SM-1 will complement any home music system. It is sufficietly rugged to stand the abuse of the most ancient record changer, yet it will enhance the performance of the finest professional arms and turntables.

Its high outputpermits quiet operation of the most economical of kit amplifiers, while the wide response will test the finest stereo amplifier-preamplifier units on the market.

Comparision of the specifications will convince you that, for stereo cartridges, all you need say is Fairchild.
