Description
The innovative and highly anticipated all-new R-Series amplifiers are truly remarkable powerhouse masterpieces.
With a meticulous approach, every aspect of their design composition and engineering has been embarked upon to achieve sonic excellence and power performance, all-while embodied in a compact form factor. Furthermore, they incorporate advances in technology gained from the ultra-high-end Alpine Status series amplifiers.
A true class-leader, with 750W RMS of onboard power coupled to its all-digital “no shutdown” circuit design, the R2-A75M maintains peak performance at high power output achieving earth-shattering, authoritative bass at virtually any volume.
Be wowed by the bold aesthetic design and stunning build quality—from the moment you see, touch and hold these amplifiers exudes quality. With their solid cast aluminium body, precision machined finishes and high quality terminal blocks, every detail is premium and first-class.
Smaller and more powerful than ever. Alpine’s all-new exclusive digital design architecture has enabled the footprint size to be significantly reduced without compromising on audio specifications and power output.
Beneath the exquisite beauty cover panel lay the top panel controls providing convenient access to configure the amplifier and fine-tune audio calibration adjustments. What’s more, the single sided terminal layout and integrated chassis mounting makes installation a breeze.
These pint-sized, yet potent amplifiers gives you enormous and effortless power delivery, coupled with incredible audiophile-grade sound quality, making them the perfect choice for the astute system builder enthusiast and discerning music fans.
Born to be played Loud—the all-new R-Series gives you legendary performance with extreme power output matched with unrivalled sound quality and reliability.
Exquisite Design, Inside and Out
The all-new ultra-modern R-Series amplifiers are beautifully designed and constructed with machined alloy detailing and premium finishes throughout. Internally, An all-digital dual post-filter feedback loop is added for unmatched accuracy and control, while minimising internal noise.
Top Panel Controls
There when required and hidden when not, gain and crossover controls have been relocated beneath a sleek brushed alloy cover panel atop the amplifier for convenient, yet discreet use. Furthermore, mounting feet are now integrated into the chassis of the amplifier for improved aesthetics and installation simplicity.
Single Sided I/O Terminals
A considered design from every aspect, all speaker I/O is consolidated onto a single side of the chassis. This not only makes positioning and connecting the amplifier easier and more flexible, but also allows for beautifully clean installations.
Compact and Powerful
The R2-A75M has a footprint that’s a whopping 15% smaller than the outgoing model (R-A60F). This compact size greatly expands installation flexibility, making it suitable for almost any vehicle application while still punching out the same potent performance.
Trickle-Down Technology
Using “trickle-down” technology inspired design, and performance cues from the High-Resolution Alpine Status systems, the Next-Generation R-Series Amplifiers feature Alpine’s exclusive circuit design architecture that will take this legendary system to the next level in sound performance.
Control your Subwoofer
The optional RUX-KNOB.2 remote bass knob controller (sold separately) connects directly to R-Series amplifiers, providing easily accessible subwoofer control to make bass adjustments on the fly to enhance your listening experience. Its tiny dimensions allow it to be mounted in a number of handy locations for convenient control.
Better than Ever
A pillar of Alpine’s best-ever lineup of R-Series, Next Generation R-Series amplifiers provide pinnacle performance matched to the powerful and authoritative bass of R-Series Shallow Mount Subwoofers or stunning clarity of R-Series Speakers. R-Series components are designed to be played loud, for a detail rich and immersive experience thanks to their Hi-Res Audio specifications.
