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.

Clarion series UFO



Il marchio Clarion conosciuto oggi sopratutto come il produttore leader nel settore dei impianti car stereo, ma nel suo passato ha realizzato anche i sistemi di hi fi per ascolto domestico. Uno dei sistemi meglio riusciti è il famoso "UFO series" prodotto tra 1977 e 1978. Un sistema senza precedenti. Nell' estetica, perchè il design di ogni elemento è concepito in modo da essere perfettamente compatibile con quello degli altri, cosi da farne un perfetto tutt'uno. Nell'ascolto, perchè l'elettronica dei singoli elementi è perfettamente in simbiosi con quella degli altri, anzi, concepita in modo da ottimizzare la qualità del suono.
Il sistema è composto da 3 elementi principali come: MT 7800; MA 7800; MD 7800.
Per completare un impianto c'e' ancora il giradischi MP 78000
