Abstract

Egaliseur pour la correction de courbe de réponse en fréquence d'une chaîne électroacoustique. L'égaliseur comprend trois voies 1, 2, 3 en parallèle, entre l'entrée E et un amplificateur de sortie 4, chacune des trois voies se terminant par un atténuateur 19, 29, 39. La voie 1 est un amplificateur apériodique, les voies 2 et 3 sont des filtres actifs passe-bande, dont la fréquence centrale est choisie par sélection des condensateurs 22, 23 et 32, 33, l'amortissement étant réglé par les résistances 26 et 36. Les fréquences centrales peuvent être choisies sur toute l'étendue du spectre. L'égaliseur introduit un minimum de déphasage et se prête à la réalisation d'effets spéciaux. Application à l'enregistrement acoustique professionnel.
