Introd uc tion
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 technol-
ogy 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 experi-
ence.
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.
I 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.
I 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.
I 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.
I 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.

tions.
Failure to heed them can result in
serious injury or death.
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 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.
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.
KEEP THE VOLUME AT A LEVEL WHERE YOU
CAN STILL HEAR OUTSIDE NOISE WHILE
DRIVING.
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.
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.
DO NOT DAMAGE PIPE OR WIRING WHEN
DRILLING HOLES.
When drilling holes in the chassis for installa-
tion, take precautions so as not to contact,
damage or obstruct pipes, fuel lines, tanks or
electrical wiring. Failure to take such precau-
tions may result in fire.
USE THIS PRODUCT FOR MOBILE 12V
APPLICATIONS.

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.
5-EN
Insta lla tion
Due to the high power output of the MRV-F900, considerable heat is produced when the
amplifier is in operation. For this reason, the amplifier should be mounted in a location which will
allow for free circulation of air, such as inside the trunk. For alternate installation locations,
please contact your authorized Alpine dealer.
1. Using the amplifier as a template, mark the four screw locations.
2. Make sure there are no objects behind the surface that may become damaged during drilling.
3. Drill the screw holes.
4. Position the MRV-F900 over the screw holes, and secure with four self-tapping screws.
NOTE:
To securely connect the ground lead, use an already installed screw on the metal part of the
vehicle (marked (#)). Be sure this is a good ground by checking continuity to the battery (–)
terminal. As much as possible connect all equipment to the same ground point. These proce-
dures will help eliminate noise.
