At Alpine, Sonic Excellence is a goal we consider most important. Your
purchase of this component has told us you feel the same. We take great
pride in the long tradition of excellence in sound quality and reliability that the
Alpine
name
represents.
Now
as
a
part
of
that
tradition,
we
welcome
you
to
the growing number of discerning audiophiles who own Alpine products.
This
manual
has
been
prepared
to
help
you
maximize
your
enjoyment
of
the
outstanding
performance
&
features
of
your
new
Alpine
MRV-F400
4/3/2
Channel
Power
Amplifier.
This
power
amplifier
incorporates
many
advanced
technical
&
perform-
ance
features.
To
realize
the
exceptional
performance
for
which
this
product
is
capable,
it
is
necessary
that
all
signal
sources,
speakers
and
interconnec-
tion
devices
are
of
the
highest
sonic
quality.
We
recommend
Alpine
Head-Units,
Crossovers,
Speaker
Systems,
High
Quality
Interconnection/Speaker
Cables
&
Accessories
wherever
possible.
Due
to
the
complexity
of
this
product,
we
strongly
recommend
that
the
MRV-F400
be
installed
by
your
authorized
Alpine
dealer.
Please study this manual carefully and become acquainted with all the
special features and capabilities of your new MRV-F400. Should you have
any questions, please consult your authorized Alpine dealer.

POWER-ON INDICATOR
This indicator illuminates in green when the amplifier is on and operational.
BUILT-IN ADJUSTABLE CROSSOVER (50 — 200 Hz HP/LP)
A pair of built-in, switchable and independent adjustable crossover network at 50
~ 200 Hz, 12 dB per octave, can be used to set up the amplifier for low-pass
(subwoofer) or high-pass (tweeter/midrange satellite) applications. These net-
works can also be switched off to allow full-range signal amplification.

MULTI-MODE™ CAPABILITY
DUO-8B FEEDBACK CIRCUITRY AND S.T.A.R. CIRCUITRY
Alpine's proprietary Duo-Beta is a technologically advanced form of feedback
circuitry. Duo-Beta supplies low negative feedback throughout the audio fre-
quency bandwidth and very high negative feedback at DC. This stabilizes the
amplifier, removes DC offset, and offers excellent total harmonic distortion
(T.H.D.) characteristics. It also provides low transient intermodulation distortion
(T.I.M.), excellent slew rate, stability, and musicality.
NO CURRENT LIMITING
Absence of current limiters in the audio section ensures low T.I.M., excellent
transient response, and superb sonic quality.
INPUT MODE SELECTOR (MONO/ST/L+R)
This switch allows the user to specify the input signal entering the amplifier.
INDEPENDENT, CONTINUOUSLY ADJUSTABLE GAIN CONTROLS FOR
CH1/2 AND CH3/4
Allow different level settings for both pairs of channels.
GOLD-PLATED RCA INPUT/OUTPUT CONNECTORS
For the most accurate signal transmission and lowest possible loss. Gold-plated
terminals are immune to signal deterioration caused by corrosion in the connec-
tors that can develop over time.
GOLD-PLATED SCREW-DOWN POWER AND SPEAKER TERMINALS
For the high definition, minimum loss power transfer and oxidation resistance.
HIGH PERFORMANCE, LOW NOISE, AUDIOPHILE QUALITY ACTIVE AND
PASSIVE COMPONENTS
For the best possible performance and consistency from unit to unit.

Improper wiring connections could cause damage to your vehicle's electrical
system and/or the MRV-F400 amplifier. Carefully follow the wiring instructions in
this manual.
Attaching the battery lead to the positive (+) terminal of the battery should be the
last connection after all other connections are made. ~
Due to the high power output of the MRV-F400, it is important that all connections
are clean and well secured, or damage could result.
Be sure that the MRV-F400 is mounted in a way that will allow for free air circula-
tion and heat dissipation.
When changing fuses, be sure to replace the old fuse with one of the same
amperage. Use of improper fuses can lead to serious damage to components.
