Alpine 3555 - Power Supply and Output Stage; Input Connectivity and Gain Settings; Build Quality and Protection Features

FEATURES
DC-TO-DC SWITCHING MODE POWER SUPPLY
Provides excellent power output throughout the audio bandwidth (20 Hz to 20 kHz).
its soft clipping characteristics ensure superb transient response and musicality.
FULLY DISCRETE, COMPLEMENTARY OUTPUT CIRCUITRY
For excellent reliability, superb sonic performance and high current capability for
accurate transient response.
INDEPENDENT, CONTINUOUSLY ADJUSTABLE GAIN CONTROLS FOR CH1/2
AND CH3/4
Allow different level settings for both pairs of channels.
GOLD-PLATED RCA INPUT CONNECTORS
For most accurate signal transmission and lowest possible loss. Gold-plated terminals
are immune to signal deterioration caused by corrosion in the connectors that can
develop over time.
GOLD-PLATED, SCREW-DOWN POWER AND SPEAKER TERMINALS
For high definition, minimum loss power transfer and oxidization resistance.
HIGH PERFORMANCE, LOW NOISE, AUDIOPHILE QUALITY ACTIVE AND
PASSIVE COMPONENTS
For best possible performance and consistency from unit to unit.
THIRD-ORDER, (18 dB PER OCTAVE) CAPACITIVE/INDUCTIVE POWER SUPPLY
INPUT AND OUTPUT FILTERING
Prevents radio frequency interference (RFI) and immunity to system noises (such as
alternator whine).
EXTRA HEAVY DUTY CONSTRUCTION
Glass-epoxy printed circuit boards and separate high current power transfer bus-bars
for primary voltage and ground connections inside the amplifier.
