JPA260/JPA285

Low Pass Filter (LPF)

The Low Pass Filter controls adjust the crossover point from 40Hz to 250Hz. Typical crossover is between 60Hz and 80Hz for ported and sealed enclosures. Bandpass boxes will typically use a higher crossover setting between 125Hz and 175Hz. Depending on your sub-woofer/box combination, the crossover may be set anywhere between 40Hz and 250Hz. Since musical tastes vary, you should play music that you would normally listen to in your vehicle, with the above settings as a starting point. If necessary, set the crossover by ear.

High Pass Filter (HPF)

The high pass filter will limit the low frequencies being transmitted to your speakers. This can be useful in number of situations. For example, if you selected the high pass filter and set the crossover to 40Hz, then you would have an infra-sonic (sub-sonic) filter at 40Hz, which would be useful with certain enclosure/subwoofer combinations that were tuned between 45 – 50Hz. Other uses might include limiting the low frequencies to smaller speakers (61/2", 6 X 9", etc.) by adjusting the crossover to a higher setting (80 – 100Hz).

Crossover (X-OVER)

The JPA series of amplifiers have built-in low-pass and high- pass crossover filters for bi-amplifying the system. Adjust the crossover to accommodate your chosen installation method. Select LPF (low pass filter) when the amplifier will be driving woofers or subwoofers. Choose FULL when crossover mode is not active and the amplifier is in “full range” mode. Select HPF (high pass filter) when the amplifier will be driving full- range or separate speakers, and you want to limit the “bass” being transferred to these speakers.

Filtro de Bajo Paso (LPF)

Estos controles ajustan el punto de cruzamiento desde 40 Hz a 200 Hz. El cruzamiento típico es entre 60 Hz y 80Hz. El cruzamiento típico de paso alto es entre 125 Hz y 175 Hz. La cruce se puede fijar dondequiera entre 40Hz y 200Hz. Debido a que el gusto musical varía, utilice la configuración siguiente como punto de partida y ajuste el cruzamiento de oído mientras escuche la música de su preferencia. Asegúrese de colocar en plano los controles de tono de la unidad principal antes de ajustar el cruzamiento.

Filtro de Alto Paso (HPF)

El filtro de alto paso limitará las frecuencias bajas que pasen a sus altavoces. Esto puede ser útil en diferentes situaciones. Por ejemplo, si usted seleccionó un filtro de alto paso y configuró el cruzamiento a 40Hz, entonces usted tendría un filtro infrasónico (subsónico) a 40Hz, lo cual sería útil con ciertas combinaciones de cercamientos/altavoces de graves que fueron sintonizados entre 45

-50Hz. Otros usos incluirían limitar las frecuencias bajas a altavoces menores (6 1/2", 6 X 9", etc.) ajustando el cruzamiento a una configuración más alta (80 - 100Hz).

Cruce (X-OVER)

Los amplificadores JPA tienen cruces integrados de paso bajo y paso alto para amplificar doblemente su sistema. Regule el cruce para adecuarlo al método de instalación seleccionado. LPF (Filtro de paso bajo) – seleccione este filtro cuando el amplificador vaya a accionar bajos y contrabajos. FULL–El cruce no está activo, y el amplificador está en el modo “rango total”. HPF (Filtro de paso alto)

seleccione este filtro cuando el amplificador vaya a accionar altoparlantes de rango completo/separados, y desea limitar los “bajos” que van a estos altoparlantes.

Filtre passe bas (LPF)

Ces contrôles ajustent le point de croisement de 40Hz à 200Hz. Un croisement typique est entre 60 Hz à 80 Hz. Un croisement haut passe typique est entre 125Hz et 175Hz. Le croisement peut être placé n'importe où entre 40Hz et 200Hz. Puisque les goûts en musique varient, utilisez les réglages ci-dessus comme un point de départ et ajustez le croisement par oreille lorsque vous écoutez la musique de votre choix. Soyez sûrs de mettre les contrôles de tonalité des installations en tête à plat avant d'ajuster les croisements.

Filtre passe haut (HPF)

Le filtre passe haut va limiter les fréquences basses allant vers votre haut parleur. Cela peut être utile dans des situations différentes. Par exemple, si vous avez sélectionné un filtre passe haut et réglé l'aire de recouvrement à 40 Hz, vous aurez alors un filtre infrasonique (sous-sonique) à 40Hz, qui serait utile avec certaines combinaisons caisson de basse/clôture qui ont été syntonisées entre 45-50 Hz. D'autres utilisations peuvent comprendre limiter les fréquences basses aux petits hauts parleurs (61/2'', 6'' x 9'') en ajustant l'aire de recouvrement à un réglage plus haut (80-100Hz).

Filtrage (X-OVER)

Les amplificateurs JPA ont un sélecteur intégré pour les transferts (filtre passe-bas - FPB, et filtre passe-haut - FPH), afin de commuter la fréquence de coupure de deux amplificateurs connectés à l'unité. Réglez le dispositif de filtrage en fonction du type d’installation choisi. LPF (Filtre passe-bas) - Choisissez ce filtre si l’amplificateur doit être raccordé à des hautparleurs de graves ou d’extrêmes graves. FULL - Le filtre est mis hors fonction et l’amplificateur rehausse l’ensemble des fréquences. HPF (Filtre passe-haut) - Choisissez ce filtre si l’amplificateur est raccordé à des haut-
