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.

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.

@ Installation Method for the Shielding of Car Noise
Introduction
Measures against car noise are very important for delivering the best perform-
ance from your audio system. In view of this, this product should be installed properly
to suppress the effects of car noise.
Here we present a basic installation method for suppressing car noise.
Keeps the equipment away from the car harness. (Fig. A)
The car harness which is wired throughout the car might be exposed to the
entrance of noise from the various electrical parts in the car.
A basic audio installation practice is to install the main component away
from the car harness and wire it at that location.

Do not have the power system and the signal system close together. (Fig. B)
When making a new audio wiring installation, a basic practice is to do the
wiring as far away from the battery power cable as possible.
lf wired together, the noise will enter the RCA cable from the battery power
supply.

A
power
supply
filter
is
the
first
step
in
noise
prevention.
(Fig.
C)
Use
of
a
power
supply
filter
is
the
first
step
in
preventing
noise
from
entering
the
audio
system
from
the
power
line
that
branches
from
the
car
harness.
Note
that
when
current
flows
through
a
power
supply
filter
a
magnetic
field
is
produced
and
this
can
effect
the
audio
as
a
noise.
The
installation
location
of
the
power
supply
filter
is
also
an
important
factor.
Car Harness
Power Supply Filter
Fig. C
The
amount
of
noise
will
vary
depending
on
the
quality
of
the
ground.
(Fig.
D)
The
current
drawn
by
the
audio
equipment
flows
from
the
power
line
through
the
equipment
and
then
back
to
the
car
body
through
the
ground
wire.
When
a
stress
is
produced
on
this
current,
noise
is
introduced.
Like
the
power
line,
the
ground
is
an
important
factor.
When
fastening
the
ground
wire
by
a
screw,
the
essential
point
is
to
cleanly
remove
the
coating
from
the
car
chassis
to
allow
the
current
to
flow
easily.
*
Alpine
has
a
variety
of
power
supply
filters
(surge
suppressors)
for
noise
preven-
tion
applications.

further
details,
contact
your
store
of
purchase.

Refer to Fig. 2 on page 4.
Due to the high power output of the MRV-F400, 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-F400 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 procedures will help eliminate noise.
