Features

•

4/3/2 CHANNEL OPERATION - Can be used in a 4
channel mode providing 25W x 4 into 4 ohms or 35W
x 4 into 2 ohms, or in mono mode producing 70W x 2
into 4 ohms. (all power ratings are from 20Hz to 20kHz
at 12V DC).

•

MULTIMODE™ CAPABILITY - The 3527Vcan oper-
ate in 2-channel stereo and bridged mono modes
simultaneously.

•

ACTIVE DIVIDING NETWORK - A built in electronic
crossover network (18 dB per octave) can be used to
set up the amplifier for low pass (80Hz and down) or
high pass (80Hz and up) 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.

•

LINE AND SPEAKER LEVEL INPUT CAPABILITY -
In addition to RCA-type line inputs, balanced low
impedance speaker inputs can be connected to high or
standard power head units that do not have pre-amp
outputs. The head unit's internal fader and balance
controls will continue to function properly.

•

INPUT MODE SELECTOR SWITCH - Stereo; ch1
