An automatic mixer apparatus is described which comprises a plurality of channels each including a level detecting circuit, a comparator and a voltage control amplifier, a gain control circuit for controlling the gains of the voltage control amplifiers of the respective channels and a mixer circuit for mixing signals from the voltage control amplifiers. The level detecting circuit detects a level of an aural signal received at the corresponding channel and the comparator operates to compare the detected level from the detecting circuit and a reference level. When the detected level is higher than the reference level, the comparator outputs a comparison signal to the corresponding voltage control amplifier to turn on. The gain control circuit receives the comparison signals from the whole comparators and outputs a gain control signal to the respective voltage amplifiers whereby the gains thereof are controlled in accordance with the number of the comparison signals received at the gain control circuit.

L'invention est un appareil de mixage automatique qui comprend une pluralité de canaux incluant chacun un circuit détecteur de niveau, un comparateur et un amplificateur de commande de tension, un circuit de commande de gain utilisé pour commander les gains des amplificateurs de commande de tension des divers canaux et un circuit de mixage servant à mixer les signaux de sortie des amplificateurs de commande de tension. Le circuit détecteur de niveau détecte le niveau d'un signal sonore reçu dans l'un des canaux et le comparateur compare ce niveau avec un niveau de référence. Quand le niveau du signal détecté dépasse le niveau de référence, le comparateur transmet un signal de comparaison à l'amplificateur de commande de tension correspondant pour mettre celui-ci sous tension. Le circuit de commande de gain reçoit les signaux de comparaison de tous les comparateurs et transmet un signal de commande de gain aux amplificateurs de tension respectifs et les gains des amplificateurs sont alors commandés selon le nombre des signaux de comparaison reçus par le circuit de commande de gain.
