À propos de l’enregistrement stéréo M-S

Le format de signal M-S du MKH 418 S permet de doser facilement l’équilibre entre l’information principale, captée par le micro central (M) et les informations « spatiales » délivrées par le micro latéral

(S). Vous pouvez même effectuer ce dosage après l’enregistrement, sans aucune perte si vous avez pris la précaution d’enregistrer les deux signaux M et S tels quels sur des pistes séparées. Le signal M-S est ensuite converti au format X-Y (micros coïncidents), qui permet une écoute stéréophonique classique, selon la formule suivante : X = M + S, Y = M – S (matriceur). Ce processus s’appelle le matriçage. La proportion de signal S détermine la largeur stéréo, autrement dit l’impression d’espace sonore, il faut donc doser le signal S avec soin, en fonction de la situation d’enregistrement. Pour éviter tout compromis et laisser une latitude de choix maximale à l’utilisateur, le MKH 418 S n’intègre pas de matriceur M-S —> X-Y en sortie.

Si votre table de mixage ne propose pas de fonction de matriçage, vous pouvez utiliser la méthode dite « des trois faders » (voir schéma). Il faut envoyer le

Le signal S doit être envoyé sur deux voies de consoles à la fois ; le potentiomètre de panoramique de l’une à fond à gauche, celui de l’autre voie à fond à droite, et il faut inverser la phase du canal droit. Les faders des deux voies S doivent être couplés, mécaniquement ou électroniquement.
