Alpine 3522S - Features; Channel Operation Modes; Advanced Circuitry and Sound Quality

FEATURES |
2/1 CHANNEL OPERATION
The 3522S can be used as:
a. 2-channel amplifier, producing 30W per channel into 4 Q, or 40W per
channel into 2 Q.
b. 1-channel amplifier, producing 80 W per channel into 4 Q.
MULTIMODE CAPABILITY
Multimode capability allows the 3522S to operate in its 2-channel stereo,
and bridged mono modes simultaneously. This-way, the amplifier can
power a pair of satellite speakers, along with a bridged mono subwoofer,
and/or a true center channel speaker.
3, 2, OR 1 CHANNEL OPERATION
Thanks to its Multimode capability, the 3522S can simultaneously drive a
pair of satellite speakers in stereo, along with a bridged mono subwoofer
(and/or center channel speaker) for a total of 3 channels. In addition to
Multimode, the 3522S can be driven in a conventional 2-channel mode,
or its two channels can be bridged into a single channel of considerably
higher power output.
ACTIVE DIVIDING NETWORK
A built-in, switchable electronic crossover network at 80 Hz, 18 dB per
octave, can be used to set up the amplifier for low-pass (subwoofer) or
high-pass
(tweeter/midrange
satellite)
applications.
This
network
can
also
be switched off to allow full-range signal amplification.
DUO-B FEEDBACK CIRCUITRY
This
stabilizes
the
amplifier,
removes

and
offers

characteristics.
It
also
provides
low
T.1.M.,
excellent

factor,
stability,
and
musicality.
NO CURRENT LIMITING
Absence
of

ensures
low
T.1.M.,
excellent
transient

and
superb
sonic
quality.
S.T.A.R. CIRCUITRY
The Alpine-developed Signal Transit for Accurate Response circuit
topology improves sonic properties by reducing interaction between
different sections of the circuitry.
INPUT MODE SELECTOR
This switch allows the user to specify the input signal entering the ampli-
fier. Among other benefits, it eliminates the need for RCA-type Y-
adaptors when bridging the amplifier.
