c) Set to the "OFF" position when the ampli- fier will be used for driving full-range speakers. The full frequency bandwidth will be output to the speakers with no high or low frequency attenuation.

ä,ç,è 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.

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

ã,é,ê Input Gain Adjustment Control

Set the MRV-F357/MRV-F307/MRV-T707/MRV- T407 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.

c) Régler sur la position "OFF" lorsque l'am- plificateur est utilisé pour exciter les haut- parleurs de large bande. La bande entière sortira aux haut-parleurs sans que les fré- quences basses ou hautes soient coupées.

ä,ç,èBouton de réglage de la fréquence de trans- fert

ã,é,ê Contrôle de réglage de gain d'entrée Régler les boutons de gain d'entrée du MRV-F357/MRV-F307/MRV-T707/MRV-T407 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.

b) Fíjelo en la posición "HP" cuando se utilice el amplificador para excitar el sistema de altavoz de agudos/tonos medios. Las fre- cuencias bajo el punto de cruce se corta- rán (a razón de 12 dB por octava).

c) Ajuste a la posición desactivada ("OFF") cuando el amplificador se utilice para ex- citar un sistema con altavoces que repro- duzcan la gama completa de frecuencias. La anchura de banda total se emitirá sin cortar ni las frecuencias altas ni las bajas.

ä,ç,èBotón 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.

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

ã,é,ê Controles de ajuste de ganancia de entrada Ajuste los controles de ganancia de entrada del MRV- F357/MRV-F307/MRV-T707/MRV-T407 a su posi- ción mínima (4V). Utilizando una cassette o mejor un CD como fuente, aumente el volumen de la uni- dad principal hasta que haya distorsión. Después, reduzca de un paso el volumen. Usted podrá enton- ces aumentar la ganancia del amplificador hasta que el sonido de los altavoces salga distorsionado.

MRV-T407, MRV-F357, MRV-F307, mrv-t707 specifications

Alpine has long been a pioneer in the world of car audio, and its MRV series amplifiers exemplify the company’s commitment to delivering high-quality sound and robust performance. The MRV-T707, MRV-F307, MRV-F357, and MRV-T407 models showcase cutting-edge technologies and features that make them ideal for both audiophiles and casual listeners alike.

Starting with the MRV-T707, this powerful two-channel amplifier is built to deliver clean and dynamic sound. With an RMS power output of 130 watts per channel at 4 ohms, it can drive both speakers and subwoofers with authority. The compact design allows for easy installation in tight spaces, while the proprietary D-Class technology ensures high efficiency, minimizing heat while maximizing output. The built-in low-pass filter enables precise tuning of subwoofer performance, allowing users to tailor their audio experience.

The MRV-F307 introduces versatility into the mix, functioning as a four-channel amplifier. With an RMS power rating of 75 watts per channel at 4 ohms, it's perfect for driving multiple speakers in a car system. This amplifier also features high-level inputs, which means it can be connected to factory-sound systems without requiring aftermarket head units. This feature, along with its advanced equalization capabilities, allows for customization and enhanced sound reproduction across all frequencies.

Moving on to the MRV-F357, it slightly boosts the power output to 100 watts per channel at 4 ohms. This model stands out with its bridgeable channels, meaning it can be configured to deliver higher power to fewer speakers, offering flexibility in system setup. The thermal protection circuitry ensures the amplifier runs smoothly without risk of overheating, which is essential during long drives or high-volume listening sessions.

Lastly, the MRV-T407 amplifies performance with its impressive power ratings, providing 150 watts per channel at 4 ohms. This model targets serious enthusiasts looking for deep bass and crystal-clear highs. The advanced circuitry lends itself to efficient thermal management, while a sophisticated bass boost feature allows users to adjust low-end frequencies for tailored sound profiles. The aesthetics of each amplifier boast a sleek design, complemented by a rugged build quality to withstand the demands of the automotive environment.

In summary, Alpine's MRV-T707, MRV-F307, MRV-F357, and MRV-T407 amplifiers encapsulate a blend of power, efficiency, and flexibility. With features like D-Class technology, bridgeable channels, and customizable filtering options, these amplifiers set a high bar in car audio performance, making them essential components for any serious audio system. Whether for enhancing everyday listening or creating an immersive sound experience, Aqua amplifiers cater to a range of needs and preferences.
