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 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.

???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.

Installation

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.

Connections

Before making connections, be sure to turn the power off to all audio components. Connect the yellow battery lead from the amp directly to the positive (+) terminal of the vehicle's battery. Do not connect this lead to the fuse block.

To prevent external noise from entering the audio system.

???Locate the unit and route the leads at least 10 cm away from the car harness.

???Keep the battery power leads as far away from other leads as possible.

???Connect the ground lead securely to a bare metal spot (remove any paint, dirt or grease if necessary) of the car chassis.

???If you add an optional noise suppressor, connect it as far away from the unit as possible. Your Alpine dealer carries various noise suppressors. Contact them for further information.

???Your Alpine dealer knows best about noise prevention measures so consult your dealer for further information.

1RCA Input Jacks

Connect these jacks to the line out leads on your head unit using RCA extension cables (sold separately).

2Speaker Output Terminals

The MRV-F900 has one set of speaker outputs. Be sure to observe correct speaker output connections and phasing. Connect the positive output to the positive speaker terminal and the negative to negative.

Do not use the speaker (???) terminals as a common lead between the left and right channels. Do not connect this lead to the vehicle???s chassis.

NOTES:

???Do not connect speaker leads together or to chassis ground.

???Do not connect the speaker output terminals to the battery lead or to the ground lead. Otherwise it may result in malfunction or fire.

4Battery Lead (Sold Separately)

Be sure to add a fuse as close as possible to the MRV-F900???s battery terminal. This fuse will protect your vehicle???s electrical system and the MRV-F900 in case of a short circuit. If you need to extend this lead, the wire gauge should be AWG4 or larger.

NOTES:

???Please make sure not to short the exposed connector to any grounded metal surface when replacing the fuse or making initial connection.

???When adding a fuse to the battery lead, be sure to use the 80A fuse (supplied) with its fuse holder (supplied).

???Do not place the fuse holder (supplied) in the vehicle???s engine compartment because of the high temperatures reached in this area.

???In order to protect the vehicle???s battery and the wiring, be sure to use an equivalent replacement for the supplied (80A) fuse.

???The fuse holder (supplied) corresponds to an 80A fuse or lower. It is not suitable for a fuse rated higher than 80A.

5Ground Lead (Sold Separately)

Connect this lead securely to a clean, bare metal spot on the vehicle chassis. Verify this point to be a true ground by checking for continuity between that point and the negative (???) terminal of the vehicle's battery. Ground all your audio components to the same point on the chassis to prevent ground loops.

6Remote Turn-On Lead (Blue/White, Sold Separately)

Connect this lead to the remote turn-on or power antenna (positive trigger, (+) 12V only) lead of your head unit.

WARNING

Be careful of battery wiring.

Be sure to use attached FUSE.

Don't connect Battery without FUSE.

Cautions on wire lead connections

???Use Power Supply wire sold at your dealer???s store.

???Refer to the description below for the proper procedure.

If you are in doubt about how to make this connection, consult your dealer.

1Check the wire size.

NOTES:

???Wire Size (Battery Lead, Ground Lead):

Recommended wire size for this unit is AWG4 or larger.

???Wire Size (Remote Turn-on Lead):

Recommended wire size for this unit is AWG8 ??? AWG14.

???If the wire gauge used is unknown, ask your dealer.

2Remove the insulation from the ends of the wire leads by about 7 ??? 10mm (9/32"

??? 3/8"). (Fig. 7)

NOTES:

???If length of the exposed wire is too short, a poor connection may occur causing operation failure or sound interruption.

???On the other hand, if the length is too long, an electrical short-circuit may occur.
