Crossover Network Settings

System Type 2

Filter Description:

In this system type, the woofer is in a different plane from the tweeter, making it necessary to use the phase correction sections of the network to compensate for the different relative positions. With this particular network set- ting, user adjustment of the woofer axis jumpers is not recommended due to the response correction engaged for driver placement. It is important to note that use of Blend-A in the WF-LP jumper group results in a complete bypass of the lowpass section of the network. From the graphs below, the effect of the active jumper settings can be seen.

Configuration du filtre de voies

Type de système 2

Description du filtre :

Dans ce type de système, le woofer est situé à un niveau différent de celui du tweeter ou du woofer, nécessitant ainsi l'utilisation des groupes de correction de phase du filtre afin de compenser les différences de position. Avec cette configuration spéciale du fil- tre, il est déconseillé à l'utilisateur d'ajuster les câbles de pontage en axe du woofer vu la correction de réponse générée par l'emplacement de l'amplificateur. Il est important de remarquer que l'utilisation de la solution A dans le groupe de pontage du WF-LP engendre une déviation complète du groupe passe-bas du filtre. Les graphes ci- dessous illustrent l'effet des configurations de pontage actives.

Note:

These simulations only illustrate the effect of each filter upon the input signal, and therefore do not represent the actual summed frequency response of the speaker system.

Remarque :

Ces simulations n'illustrent que l'effet de chacun des filtres sur le signal d'entrée et ne représentent donc pas la réponse en fréquence accumulée réelle du système du haut- parleur.
