R-A75M

Mono Power Density Amplifier

The new R-series amplifier come with new technology that produce high power and accurate imaging. Also, having a built-in bandpass filter which lets you design an active speaker set-up without a separate processor. Let’s experience the great sound you’re looking for.

This is a perfect power matching item for R-series speakers and amplifiers to get better experience.

Hi-Resolution audio compliant

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.

Experience with sound quality

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.

Built-in bandpass filter

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.
