MRV-F400

4/3/2 Channel Power Amplifier

Features

proves sonic properties by reducing interaction be-
tween different sections of the circuitry.

•

INPUT MODE SELECTOR-CH1 Mono;Stereo; Left +
Right

•

CONTINUOUSLY ADJUSTABLE GAIN CONTROL

•

FULLY DISCRETE, COMPLEMENTARY OUTPUT
CIRCUITRY

•

GOLD PLATED RCA INPUT CONNECTORS AND
SCREW-DOWN POWER AND SPEAKER TERMI-
NALS.

•

HIGH PERFORMANCE, LOW NOISE, AUDIOPHILE
QUALITY ACTIVE AND PASSIVE COMPONENTS

•

PULSE WIDTH MODULATED (PWM) DC-DC
POWER SUPPLY- Alpine developed a new type of
PWM power supply that maintains rated power out-
put down to 12 V DC and allows for an approximately
40% increase in output power at higher, real world,
battery levels.

•

LED STATUS MONITOR

•

NON-FADED PRE-AMP OUTPUT- A set of non-fad-
ing preamp outputs are included which can eliminate
the need for RCA "Y" connectors and allows for greater
system flexibility.

•

4/3/2 CHANNEL OPERATION-Can be used in a 4-
channel mode providing 40 Wx4 into 4 ohms or 50 W
x4 into 2 ohms, or in a two channel mode producing
100W x 2 into 4 ohms (all power ratings are from 20
Hz to 20 kHz at 12V DC).

•

MULTIMODE

TM

CAPABILITY-

The MRV-F400 can

operate in 2-channel stereo and bridged mono modes
simultaneously.

•

ACTIVE DIVIDING NETWORK-A built in variable
electronic crossover network form 50 - 200 Hz (12 dB
per octave) is independent for channels 1/2 and 3/4
and can be used to set up the amplifier for low pass
or high pass applications. This network can also be
switched off to allow full-range operation

•

DUO-ß FEEDBACK CIRCUITRY-Supplies low nega-
tive feedback throughout the audio frequency band-
width and very high negative feedback at DC. This
stabilizes the amplifier, removes the DC offset, of-
fers excellent total harmonic distortion (THD), and
provides low transient intermodulation distortion
(TIM).

•

NO CURRENT LIMITING - Absence of current lim-
iters in the audio section ensures low TIM, excellent
transient response and superb sound quality.

•

S.T.A.R. CIRCUITRY - Alpine-developed Signal Tran-
sient for Accurate Response circuit topology im-
