UTILISATION DE FILTRES

Un filtre est un circuit utilisant des condensateurs ou bobines et qui est placé sur les fils du haut-parleur, entre l’ampli et le haut-parleur. Le filtre délègue une gamme de fréquences spécifique au haut-parleur afin d’assurer une performance optimale de l’ampli. Un filtre peut accomplir une des trois fonctions suivantes : passe-haut (condensateurs), passe-bas (inducteurs ou bobines) et passe-bande (combinaison de condensateur et de bobine).

Les filtres les plus fréquemment utilisés sont les filtres de 6 dB/octave. Ils sont faciles à fabriquer et

nécessitent un composant par filtre. Placé en série avec le circuit, ce type de filtre réduit la puissance du haut-parleur de 6dB/octave au-dessus et au-dessous du point de fréquence, selon qu’il s’agit d’un filtre passe-haut ou passe-bas. Des systèmes plus complexes (12 dB/octave ou 18 dB/octave) peuvent causer des problèmes d’impédance s’ils ne sont pas conçus par des professionnels.

La précision des filtres dépend directement de l’impédance du haut-parleur et de la valeur du composant. Si des composants de filtre sont utilisés dans des systèmes à plusieurs haut-parleurs, il faut tenir compte de l’effet du filtre sur l’impédance globale ainsi que de l’impédance du haut-parleur pour déterminer les charges de l’ampli.

!

MISE EN GARDE : ces amplificateurs ne sont pas recommandés pour des charges

d'impédance inférieures à 2 stéréo et 4 pontées (mono).
