MRV-1000

2/1 Channel V12 Series Power Amplifier

Specifications and design are subject to change without notice.

Features

•

2/1 CHANNEL OPERATION - Can be used in a 2
channel mode providing 100W x 2 into 4 ohms or
200W x 2 into 2 ohms, or in mono mode producing
400W x 1 into 4 ohms. (all power ratings are from 20Hz
to 20kHz at 12V DC).

•

MULTIMODE™ CAPABILITY - The MRV-1000 can
operate in 2-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 nega-
tive feedback throughout the audio frequency band-
width and very high negative feedback at DC. This
stabilizes the amplifier, removes the DC offset, offers
excellent total harmonic distortion (THD), and pro-
vides low transient intermodulation distortion (TIM).

•

NO CURRENT LIMITING - Absence of current limit-
ers 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 improves

sonic properties by reducing interaction between dif-
ferent sections of the circuitry.

•

•

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 12V DC and allows for an approximately
40% increase in output power at higher, real world,
battery levels.
