Features
•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 canoperatein4-channelstereoandbridgedmono 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 interactionbetweendifferentsectionsofthecircuitry.
•INPUT MODE SELECTOR SWITCH - Mono; Stereo; Left + Right.
•CONTINUOUSLY ADJUSTABLE GAIN CONTROL
•FULLY DISCRETE, COMPLEMENTARY OUTPUT CIRCUITRY
•GOLD PLATED RCA INPUT CONNECTORS
•GOLD PLATED SCREW-DOWN POWER AND SPEAKER TERMINALS
•HIGH PERFORMANCE, LOW NOISE, AUDIOPHILE QUALITY ACTIVE AND PASSIVE COMPONENTS
•MOSFET PULSE WIDTH MODULATED (PWM) 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.
•ISOLATED AUDIO AND POWER SUPPLY SECTIONS
