Description
Alpine's legendary R collection
Alpine R-Series includes amplifiers, subwoofers and separate sets and coaxial speakers. Over the years, the R-Series has already become a kind of concept when you want the best possible sound quality, performance and reliability for the sound side of the car.
The new R-Series amplifiers further reinforced this notion.
R2-A75M is a class D mono amplifier made for subwoofer use.
The amplifier's installation and usability are even easier, because compared to the previous model, the new R2-A75M is physically smaller than its predecessor and all adjustments can be found under the cover on top of the amplifier.
Smaller “footprint”
The R2-A75M is 15% smaller than its predecessor (R-A75M), but still offers as much power as its predecessor.
Versatile adjustment possibilities
Under the cover of the R2-A75M you will find all the settings of the amplifier. With Subsonic, you can cut off the lowest frequencies (8Hz-40Hz) and the adjustment range of the low-pass filter is 50-400 hertz. Subsonic and low-pass filter are 24dB steep. In addition, the amplifier has a Bass EQ, with which you can emphasize (0 – +12dB) the level of the Sub at 50 hertz.
Easier installation
Installability and usability have also been taken into account in the design of the amplifier. All the power, speaker and RCA connections are on the same edge, and all the controls of the amplifier can be found under the cover on top of the amplifier. In addition, the "foot print" required by the amplifier, i.e. the surface area, has been reduced by 15% compared to the previous generation R-Series amplifier.
The amplifier also does not have separate mounting feet, but the mounting holes of the amplifier are integrated into the body of the amplifier.
RUX Knob2
The Alpine R2-A75M is compatible with the optional RUX-Knob2 level control.
The R2-A75M is the perfect amplifier for R-Series subs
All R-Series amplifiers are designed to pair perfectly with R-Series subwoofers and speaker sets.
R-Series coaxial and separate sets are naturally also Hi Res Audio certified.
