,, Crossover Frequency Adjustment Knob Permits adjustment of the crossover frequency, by rotating the knob to select any frequency between 50 to 200 Hz as the crossover point.

... Adjust a crossover frequency point for the subwoofer. The adjustment range is 50 – 200 Hz over a low frequency.

,, Input Gain Adjustment Control

Set the MRV-F353/MRV-F303/MRV-T503/MRV- T303 input gain knobs to the minimum (4V) posi- tion. Using a loud cassette or preferably a CD as a source, turn up the head unit volume until it dis- torts. Then, reduce the volume 1 step. You can then increase amplifier gain until the sound from the speakers becomes distorted.

Permet le réglage de la fréquence de transfert en tournant le bouton pour sélectionner une fréquence entre 50 et 200 Hz comme point de recouvrement.

... Règle le point de recouvrement pour le haut- parleur de sous-graves. La gamme de réglage est 50 – 200 Hz sur la basse fréquence.

,, Contrôle de réglage de gain d'entrée Régler les boutons de gain d'entrée du MRV-F353/MRV-F303/MRV-T503/MRV-T303 à la position mi- nimale (4V). En utilisant une cassette ou de préfé- rence un CD comme source, augmenter le volume de l'unité principale jusqu'à ce que le son s'altère. Puis, réduire le volume d'un pas. Vous pouvez aug- menter le gain de l'amplificateur jusqu'à ce que le son des haut-parleurs devienne altéré.

,, Botón de ajuste de frecuencia del filtro divi- sor (de frecuencias)

Permite el ajuste de la frecuencia de cruce, girando el botón para seleccionar una frecuencia entre 50 y 200 Hz como punto de intersección.

... Ajusta el punto de intersección para el altavoz de frecuencias ultrabajas. La gama de ajuste es 50 – 200 Hz sobre la frecuencia baja.

,, Controles de ajuste de ganancia de entrada Ajuste los controles de ganancia de entrada del MRV- F353/MRV-F303/MRV-T503/MRV-T303 a su posición mínima (4V). Utilizando una cassette o mejor un CD como fuente, aumente el volumen de la unidad principal hasta que haya distorsión. Después, reduzca de un paso el volumen. Usted podrá entonces aumentar la ganancia del amplificador hasta que el sonido de los altavoces salga distorsionado.
