Introduction

Meeting a new challenge to realize the best sound possible for the mobile environment AlpineF#1Status

For a quarter of a century, Alpine’s goal has been the best sound in the mobile environment despite its harsh physical and electrical conditions. To overcome these severe listening conditions, Alpine has developed its own unique on-board acoustic technology. This is totally different from that of home audio. The Mobile Multimedia Era is flourishing, and recording media and reproduction technology have evolved in a remarkable fashion. For an exciting and wide range of emotional experience, sound is more important than ever, and is becoming the central factor.

In the fashion of the master artisans of musical instruments, Alpine has concentrated its incomparable craftsmanship to establish its standing as a Mobile MultiMedia specialist. Alpine’s technical foundation is based on its unique technology and expertise accumulated through years of experience. Alpine constantly strives to deliver the best possible sound in this new era with an approach called “micro-dynamics.” This approach consists of micro- and macroscopic- technological analysis and design. This gives Alpine the ability to deliver increased precision in reproduction speed and time measurement, to maximize the musical sensory experience.

The best sound in the mobile environment promises the most advanced multimedia experience to serious listeners in their vehicles. Alpine F#1Status. The passionate challenge begins here.

4 Channel Amplifier

The MRV-F900 is designed to convey all the passion and impact of exceptional performances. The high fidelity circuitry of this 100W x 4-channel power amplifier, consists of high grade audio components. This combination produces beautiful harmonics, aiming at the ultimate in craftsmanship and following the ideas of microdynamics.

■ High performance MOS-FETs used in power supply unit and final stage

Unlike regular transistors, MOS-FETs can operate at extremely high speeds. They feature low loss of broad range response as well as excellent signal response.

■ Exclusive audio high speed, high current SBD (Schottky barrier diode) used in power supply circuit

The specially designed troidal transformer aiming at low noise and a sense of power has been given the maximum possible capacity. Even the electrolyte of the electrolytic capacitor is specially ordered, a measure of the thorough considerations taken with the MRV-F900. The polarities of the parts particularly important for achieving high sound quality, such as the transformer, coils and film capacitors, are carefully controlled to achieve maximum time precision.

■ Copper foil patterns are used for the circuit boards essential for achieving high quality sound.

Their thickness is increased to boost speed at high currents. The circuit boards are made of glass epoxy. Parts have been carefully selected for their low noise levels and stable performance to achieve unprecedented high sound quality.

■ The circuitry is designed through a process of repeated simulations, and high sound quality S.T.A.R circuits are used extensively.

Far more attention than with previous tunings prioritizing static characteristics has been paid to group delay. The constants of both multiple circuits and individual components have been researched scrupulously, in a tuning process many times more extensive than in the past. As a result, the harmonic spectrum and high energy characteristics of exceptional performances is output beautifully in every detail of the sound to achieve unprecedented dynamism.

WARNING

This symbol means important instructions. Failure to heed them can result in serious injury or death.

DO NOT OPERATE ANY FUNCTION THAT TAKES YOUR ATTENTION AWAY FROM SAFELY DRIVING YOUR VEHICLE.

Any function that requires your prolonged attention should only be performed after coming to a complete stop. Always stop the vehicle in a safe location before performing these functions. Failure to do so may result in an accident.

KEEP THE VOLUME AT A LEVEL WHERE YOU CAN STILL HEAR OUTSIDE NOISE WHILE DRIVING.

Failure to do so may result in an accident.

DO NOT DISASSEMBLE OR ALTER.

Doing so may result in an accident, fire or electric shock.

USE THIS PRODUCT FOR MOBILE 12V APPLICATIONS.

Use for other than its designed application may result in fire, electric shock or other injury.

USE THE CORRECT AMPERE RATING WHEN REPLACING FUSES.

Failure to do so may result in fire or electric shock.

DO NOT BLOCK VENTS OR RADIATOR PANELS.

Doing so may cause heat to build up inside and may result in fire.

MAKE THE CORRECT CONNECTIONS.

Failure to make the proper connections may result in fire or product damage.

USE ONLY IN CARS WITH A 12 VOLT NEGATIVE GROUND.

(Check with your dealer if you are not sure.) Failure to do so may result in fire, etc.

BEFORE WIRING, DISCONNECT THE CABLE FROM THE NEGATIVE BATTERY TERMINAL.

Failure to do so may result in electric shock or injury due to electrical shorts.

DO NOT ALLOW CABLES TO BECOME ENTANGLED IN SURROUNDING OBJECTS.

Arrange wiring and cables in compliance with the manual to prevent obstructions when driving. Cables or wiring that obstruct or hang up on places such as the steering wheel, gear lever, brake pedals, etc. can be extremely hazardous.

DO NOT SPLICE INTO ELECTRICAL CABLES.

Never cut away cable insulation to supply power to other equipment. Doing so will exceed the current carrying capacity of the wire and result in fire or electric shock.

DO NOT DAMAGE PIPE OR WIRING WHEN DRILLING HOLES.

When drilling holes in the chassis for installation, take precautions so as not to contact, damage or obstruct pipes, fuel lines, tanks or electrical wiring. Failure to take such precautions may result in fire.

DO NOT USE BOLTS OR NUTS IN THE BRAKE OR STEERING SYSTEMS TO MAKE GROUND CONNECTIONS.

Bolts or nuts used for the brake or steering systems (or any other safety-related system), or tanks should NEVER be used for installations or ground connections. Using such parts could disable control of the vehicle and cause fire etc.

KEEP SMALL OBJECTS SUCH AS BOLTS OR SCREWS OUT OF THE REACH OF CHILDREN.

Swallowing them may result in serious injury. If swallowed, consult a physician immediately.

CAUTION

PRECAUTIONS

This symbol means important instructions. Failure to heed them can result in injury or material property damage.

HALT USE IMMEDIATELY IF A PROBLEM APPEARS.

Failure to do so may cause personal injury or damage to the product. Return it to your authorized Alpine dealer or the nearest Alpine Service Center for repairing.

HAVE THE WIRING AND INSTALLATION DONE BY EXPERTS.

The wiring and installation of this unit requires special technical skill and experience. To ensure safety, always contact the dealer where you purchased this product to have the work done.

USE SPECIFIED ACCESSORY PARTS AND INSTALL THEM SECURELY.

Be sure to use only the specified accessory parts. Use of other than designated parts may damage this unit internally or may not securely install the unit in place. This may cause parts to become loose resulting in hazards or product failure.

ARRANGE THE WIRING SO IT IS NOT CRIMPED OR PINCHED BY A SHARP METAL EDGE.

Route the cables and wiring away from moving parts (like the seat rails) or sharp or pointed edges. This will prevent crimping and damage to the wiring. If wiring passes through a hole in metal, use a rubber grommet to prevent the wire’s insulation from being cut by the metal edge of the hole.

Temperature

Be sure the temperature inside the vehicle is between +60°C (+140°F) and –10°C (+14°F) before turning your unit on.

Installation Location

Make sure the MRV-F900 will not be installed in a location subjected to:

• Direct sun and heat

• High humidity and water

• Excessive dust

• Excessive vibrations

Maintenance

If you have problems, do not attempt to repair the unit yourself. Return it to your Alpine dealer or the nearest Alpine Service Station for servicing.

DO NOT INSTALL IN LOCATIONS WITH HIGH MOISTURE OR DUST.

Avoid installing the unit in locations with high incidence of moisture or dust. Moisture or dust that penetrates into this unit may result in product failure.
