The invention relates to a device comprising: a circuit that is used to mix a stereo input signal with another monaural input signal, independently amplifying and/or attenuating the mixture of both signals; three active frequency dividers that are used to separate the low, medium and high frequencies; three independent amplifiers for the three separate frequency ranges; a sub-bass generator which is connected to the outlet of the low- frequency monaural amplifier; an earpiece and/or a two-way baffle system which is connected to the outlets of the medium- and high-frequency amplifiers. Optionally, said amplifier outlets can be the two channels of a stereo amplifier.
L'invention concerne un dispositif comportant : un circuit permettant de mélanger un signal stéréo d'entrée avec un signal mono d'entrée et d'amplifier et/ou d'atténuer indépendamment le mélange des signaux ; trois diviseurs de fréquence actifs permettant de séparer les fréquences basses, moyennes et hautes ; trois amplificateurs indépendants pour les trois gammes de fréquences séparées ; un générateur d'extrêmes graves relié à la sortie de l'amplificateur mono de basses fréquences ; et des écouteurs et/ou un système de haut-parleurs à deux voies reliés aux sorties des amplificateurs de moyennes et hautes fréquences. Ces sorties des amplificateurs peuvent éventuellement être les deux canaux d'un amplificateur stéréo.
