Description

All Digital Design

The all-new S-Series utilise Alpine’s advanced digital design which unlike a typical Class-D amplifier circuit adds all-digital dual post-filter feedback loop for unmatched accuracy and control, while minimising internal noise.

Thermal Protection

Along with Alpine’s new intelligent amplifier platform, the new S-Series amplifiers feature an improved heat sink and protection circuit design that eliminates thermal shut-down, for dependable music playback.

One-sided Cable Terminals

The speaker and power cable terminals are conveniently located on the left hand side of the amplifier providing an easy and clean installation. The power cable terminals accept heavy gauge cables.

Low/High-Power Speaker Signal Inputs

The S-Series amplifiers are equipped with low-level RCA inputs, which can also accept high-level speaker signal inputs. This allows for installation of the R-Series amplifiers into virtually any aftermarket or OEM factory audio system.

Control Your Subwoofer

Conveniently control your subwoofer directly from the dash with the optional RUX-KNOB.2 remote bass knob controller. This accessory is also applicable for the S-A32F for when channels 3 and 4 are bridged.

High-Pass / Low-Pass Filter

With the High-Pass and Low-Pass filter you can assign the amplification channel to be used for door speakers or a subwoofer. You can then adjust the cut-off frequency for more precise tuning.
