Abstract
AMPLIFICATEUR COMPORTANT D'UNE PART DES PREMIER ET DEUXIEME ELEMENTS D'AMPLIFICATION DONT LES SORTIES SONT RACCORDEES A UNE CHARGE, ET D'AUTRE PART UN CIRCUIT DE DIFFERENCE QUI COMPORTE UN ATTENUATEUR ET DANS LEQUEL LE SIGNAL DE SORTIE DU PREMIER ELEMENT EST COMPARE AU SIGNAL D'ENTREE POUR PRODUIRE UN SIGNAL DE CORRECTION QUI EST FOURNI AU DEUXIEME ELEMENT; LES DEUX ELEMENTS SONT EVENTUELLEMENT PRECEDES DE PRE-AMPLIFICATEURS UTILISES COMME AMPLIFICATEURS DE PUISSANCE, TANDIS QUE LE DEUXIEME ELEMENT EST MUNI EGALEMENT D'UN CIRCUIT DE DIFFERENCE PRATIQUEMENT IDENTIQUE A L'AUTRE ET MUNI D'UN ATTENUATEUR, CE CIRCUIT FOURNISSANT UN SIGNAL DE CORRECTION AU PREMIER ELEMENT D'AMPLIFICATEUR, ALORS QUE LES DEUX ELEMENTS D'AMPLIFICATION RECOIVENT LE SIGNAL A AMPLIFIER. DU FAIT QUE LES SIGNAUX DE DISTORSION ONT LA MEME PHASE SUR LA CHARGE, LA DISTORSION DEVIENT PRATIQUEMENT NULLE DANS LE CAS OU L'ATTENUATION EST LA MEME DANS LES DEUX CIRCUITS AUXILIAIRES. APPLICATION A L'EQUIPEMENT DE SALLE DE SPECTACLE.
