Alpine S-A55V 5-channel amplifier

Alpine's new S-Series product family now also includes amplifiers. 1-, 4- and 5-channel terminals are available, all of which are united by the features known from Alpine's MRV series terminals: Bomb-proof operational reliability, the highest damping coefficients on the market, an individual measurement report of the real power provided by the amplifier, advanced thermal management that guarantees uninterrupted playback and, of course, compact size and timeless stylish look.

Efficient and compact
The new digital amplifier circuit enables a larger output, while the physical dimensions of the amplifier remain very small. The S-A55V is only 28.6cm x 20.4cm in size, so it is possible to install the amplifier almost "in a car like a car" in terms of size.

Advanced heat management
The S-Series amplifiers have a renewed heat management circuit and a cooling profile, so the amplifiers do not go into protection mode when the temperature rises, but playback continues without interruption.

RCA and speaker level inputs
RCA connections can also be used as speaker-level signal inputs. The S-A55V can also be connected to the car's original stereo, if the stereo does not have RCA outputs. The S-A32F starts automatically when it receives a speaker-level signal, so the amplifier does not need a separate excitation cable in this case.
A compatible speaker-level input can be found here.

Low and high pass filters
50-400Hz low- or high-pass filtering can be selected for all channel pairs separately, and the subwoofer channel also has 0 – +12dB BassBoost

RUX-KNOB2 as an accessory
The S-A32F is compatible with Alpine's RUX-KNOB2 level control. The level control works for channel pair 3+4 when this channel pair is bridged for subwoofer use.
