Alpine S-A32F S-Series 4/3/2 Channel Class D Amplifier (RMS: 55W*4 (4Ω) 80W*4 (2Ω))

Alpine introduces the all-new S-Series amplifiers - a perfect match to the S-Series speakers. These amps have an excellent Watts-per-Euro ratio in the Class-D category, feature a very high heat resistance and won’t shut down due to overheating. They also feature excellent sound quality in their price range.

The S-Series amplifiers are available in mono, 4-channel and 5-channel configuration.

Highlights:

• Terminal Layout: One side
• Small footprint for easy installation
• Screw terminals (for speaker and power cables)
• Amplifier Type: Class-D (Digital)
• Channel Design: 4/3/2 Channel
• Thermal Management Control
• Top Mounted LED Power/Status Indicator
• Speaker Level Input with remote turn on
• Crossover: Adjustable Low-pass (LPF) / High-pass Filter (HPF)
• Gain Control: Adjustable
• Bass Control: Remote Bass Control (RUX-KNOB2) Ready

All Digital Design
       Compact and Powerful: the new digital amplification circuit allows high power output while keeping a small footprint. The S-A32F measures just 204mm in width x 204mm in length for easy installation in virtually any vehicle.

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 side of the amplifier to allow a clean installation.

Low/High-Power Speaker Signal Inputs
       The 4-Channel RCA speaker signal inputs accept low and high-power signals. This makes it easy to connect the S-A32F directly to your original car stereo, regardless of your head unit’s power output (RCA connectors with open cable leads are available separatly).

Control Your Subwoofer
       You can connect the RUX-KNOB2 remote bass knod (optional available) to the S-A32F to control the subwoofer level straight from your dash (applicable for channel 3+4 in bridged mode for subwoofer usage).

High-Pass / Low-Pass Filter
       With this filter switch you can assign the amplification channel (pair) to be used for door speakers or a subwoofer. You can then adjust the cut-off frequency for more precise tuning.
