The Alpine R-Series Sound Components
The R-Series lineup is “The Loudest Family on the Block”. The products are designed to be played loud, delivering a fun and exciting listening experience, and are known for dependable performance and high-quality sound. All R-Series components are developed to perfectly match each other.
Small Footprint
Compact and Powerful: the new digital amplification circuit allows high power output while keeping a small footprint. The R-A75M measures just 274mm in width x 223mm in length for easy installation in virtually any vehicle.
Thermal Protection
Along with Alpine’s new intelligent amplifier platform, the new R-Series amplifiers feature an improved heat sink and protection circuit design that eliminates thermal shut-down, for dependable music playback.
Bass EQ and Subsonic Filter
The Bass EQ adds a 50Hz bass boost of up to +12dB to tune your bass response, while the subsonic filter is cutting ultra-low frequencies from the input signal before being amplified. This helps to protect smaller speakers from receiving too low frequencies, minimizes power wasted from reproducing inaudible sound and protects your subwoofer in a vented enclosure from over-excursion below the tuning frequency.
Low/High-Power Speaker Signal Inputs
The 2-Channel RCA speaker signal inputs accept low and high-power signals (cables not included). This makes it easy to connect the R-A75M directly to your original car stereo, regardless of your head unit’s power output. The power cable terminal accepts heavy gauge cables of up to 4 AWG.
Control Your Subwoofer
You can connect the RUX-KNOB2 remote bass knod (optional available) to the R-A75M to controll the subwoofer level straight from your dash.
Digital Amplification Circuit
The R-A75M uses a fully digital amplification design, which allows for a much better efficiency compared to a Class-A or B design. Higher efficiency means less power is dissipated to heat, allowing for a much smaller heat sink design and therefore a smaller amplifier body.
High-End Audio Components
The Alpine R-Series amps use many audiophile grade, custom designed components to achieve excellent sound quality and accuracy. The image for example shows the high-quality, large-capacity condensers, which are custom designed for Alpine.
Best Performance with R-Series Subs
The R-A75M is designed to perfectly match the Alpine R-Series R-W12D2 and R-W10D2 subwoofers for perfect system building.
