MRV-F401
.
Features
Specifications
4/3/2 CHANNEL OPERATION - Can be used in
a 4 channel mode providing 40W x 4 into 4 ohms
or 50W x 4 into 2 ohms, or in mono mode
producing 100W x 2 into 4 ohms. (all power
ratings are from 20Hz to 20kHz at 12V DC).
MULTIMODE™ CAPABILITY - The MRV-F401
can operate in 4-channel stereo and bridged mono
modes simultaneously.
ACTIVE DIVIDING NETWORK - A built in
variable electronic crossover network from
50 - 200Hz (12 dB per octave) can be used to
set up the amplifier for low pass or high pass
applications.  This network can also be switched
off for full range applications.
DUO ß FEEDBACK CIRCUITRY - Supplies low
negative feedback throughout the audio
frequency bandwidth and very high negative
feedback at DC.  This stabilizes the amplifier,
removes the DC offset, offers excellent total
harmonic distortion (THD), and provides low
transient intermodulation distortion (TIM).
NO CURRENT LIMITING - Absence of current
limiters in the audio section ensures low TIM,
excellent transient response and superb
sound quality.
S.T.A.R. CIRCUITRY - Signal Transient for
Accurate Response. A Luxman developed circuit
design which improves sonic properties by reducing
interaction between different sections of the circuitry.
INPUT MODE SELECTOR SWITCH - Mono;
Stereo; Left + Right.

DC-DC POWER SUPPLY - Alpine developed a
new type of PWM power supply that maintains
rated power output down to 12V DC and allows
for an approximate 40% increase in output power
at higher, real world, battery levels.
TOP MOUNTED LED POWER INDICATOR
NON-FADING PRE-AMP OUTPUT - A set of
non-fading preamp outputs are included which
can eliminate the need for RCA "Y" connectors
and allows for greater system flexibility.
DC STRAIGHT DESIGN - Fewer components in
the audio path to improve sound quality.
SOLID COPPER BUS BARS - Improved power
transfer and less voltage drop in power supply.
LARGE INTERNAL CAPACITANCE -  The
MRV-F401 has 16,400uF of internal capacitance.
