Alpine R-A75M Mono Class D Subwoofer Amplifier



Alpine has consistently developed innovative, top-quality car audio devices for vehicle manufacturers and the consumer market around the world. Alpine prides itself to fully satisfy those who are eager to customize their car interiors with the latest, high-quality components and has established its position as a global brand of high-end car audio systems. Alpine has also developed a diverse range of car AV products and navigation systems that provide exciting in-car audio/video experiences, as well as make driving more comfortable and safer.

The R-Series amplifiers utilize Alpine’s advanced amplifier platform that takes the classic Class-D amplifier circuit and adds dual post-filter feedback loops for unmatched accuracy and control. This technology., originally launched in the premium X-Series amplifiers,, produces efficient power with enhanced dynamic range, qualifying the R-Series amplifiers to be Hi-Resolution Audio compliant.
This new technology minimizes audible imperfections like excessive phase shift and internal noise which can deteriorate sound quality. With an incredibly low phase shift of 46°, the R-A60F 4-channel amplifier delivers accurate imaging compared to well over 100° of phase shift by a competitive amplifier model. This superior phase curve ensures a proper sound stage among the singers and instruments.
R-Series amplifiers have a built-in bandpass filter which lets you design an active speaker set-up without a separate processor. Improve the sound quality of component speakers by ditching your passive network.  Avoid added phase shifts and power losses by individually powering each component and assigning your own frequency bands for the incredible sound you’re looking for.
The “R” line of speakers and subwoofers have a heritage of sound quality you can hear from a block away, and the newly added R-Series amplifiers are no exception.  Aside from their best-in-class performance, these amplifiers are tuned to emphasize the characteristics of the R-Series speakers and subwoofers, giving you that legendary R-Series experience .
