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 combined with features familiar from Alpine MRV series terminals: Bomb-safe reliability, the toughest attenuation factors on the market, individual measurement report of actual amplifier outputs, advanced thermal management for uninterrupted playback and, of course, compact size and timeless elegant look.

Powerful and compact
The new digital amplifier circuit allows for a larger output, while keeping the physical dimensions of the amplifier very small. The size of the S-A55V is only 28.6cm x 20.4cm, so installing the amplifier is almost “car-like” in terms of size.

Advanced thermal management
The S-Series amplifiers have a revamped thermal management circuit and cooling profile, so the amplifiers do not go into protection mode when the heat rises, but playback continues uninterrupted.

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

Low and high pass filters
50-400Hz low or high pass filtering can be selected for all channel pairs separately and for the subbar channel there is also 0 - + 12dB BassBoost

Optional RUX-KNOB2
The S-A32F is compatible with the Alpine RUX-KNOB2 level controller. The level control works for channel pair 3 + 4 when this channel pair is bridged for subwoofer operation.
