High-pass filter

The high-pass filter removes ultra- low frequency information from the audio signal that could damage or cause distortion in a loudspeaker system. The DIP switch on the rear panel allows you to enable or disable the filter independently for either channel, as well as set it for either a 50 Hz or 30 Hz cut-off.

Always use the 50 Hz filter setting if you are using the amplifier to drive a distributed line system (also known as a constant-voltage line, 70-volt line, etc.).

Filtre passe haut

Le filtre passe haut élimine les informations à très basse fréquence du signal audio qui pourraient endommager le système de haut- parler ou causer de la distortion. Des interrupteurs su le panneau arrière permettent la mise en ou hors circuit des filtres individuellement, et d'en régler la fréquence à 30 Hz ou 50 Hz.

Toujours utiliser les filtres en position 50 Hz lorsque l'amplificateur est utilisé sur un système distribué (aussi connu sous l'appellation système à tension constante, ligne 70 volts, 100 volts, etc.).

Hochpaßfilter

Das Hochpaßfilter unterdrückt sehr tiefe Audiofrequenzen, die zu Zerstörungen im Lautspechersystem führen können. Die DIP-Schalter erlauben das Ein- und Ausschalten dieser Filter, unabhängig für jeden Kanal, sowohl für 30 oder 50 Hz.

Benutzen Sie immer die 50 Hz- Einstellung für den Betrieb mit 100 V Ela-Übertragern.

Filtro Pasa Altos

El filtro pasa altos elimina las frecuencias subsónicas de la señal de audio que podrían dañar o causar distorsiones en los altavoces. El conmutado DIP de la trasera permite habilitar o deshabilitar los filtros para cada canal independientemente, asi como fijar la frecuencia de corte a 50 o 30 Hz.

Emplear sienpre la frecuencia de corte de 50 Hz si estamos usando un amplificador para alimentar un sistema de distribución de audio (también conocido como línea de voltaje constante, línea de 70 voltios, etc.).
