VERSATILE SYSTEM BUILDS

The R-A90S features a staggered power channel layout that allows each channel to host different levels of power, compared to traditional, multi-channel amplifiers. This allows the R-A90S to effectively function as both a 3-way active amplifier and a 5-channel amplifier by delivering the power you need to the channels where you need it the most. Now you can use one amplifier to either power an active 3-way sound system or use it to power your speakers and subwoofer without the bulk of an additional amplifier.

Next-Level System Builds

For the best possible sound experience, use the built-in bandpass, high pass, or low pass filter to individually power each component in your sound system and assign frequency bands for accurate and reliable sound reproduction.

Proper Sound Stage

The R-A90S maintains an extremely low phase shift throughout the music spectrum which minimizing audible imperfections in your music and allows your music to stay faithful to the original recording. The result is hair-raising detail that puts you in the center of the performance.

Accurate Sound Reproduction

Using the same exclusive technology launched in Alpine’s premium X-Series Amplifiers, the R-A90S has dual “Sierra” post-filter feedback loops that correct signal distortion by making the output as close as possible to the original input. The result is music that stays true to the artist’s intention.

MUSIC IN HI-RES

Hear the subtle details you’ve been missing in your music with the R-A90S.‚ÄØWith the highest power output in its category, the R-A90S drives power to your sound system to create a big dynamic music range for the listener, reproducing‚ÄØhigh-frequency sounds up to 45k Hz, making the R-A90S Hi-Res Audio Compliant.‚ÄØ

Remote Bass Knob-Ready

The R-A90S has input capability to add an optional RUX-KNOB.2 Remote Bass Control Knob (sold separately). The remote bass knob controls the bass in your subwoofer by adjusting the gain on your amplifier for quick bass adjustments when needed.

Optimized for Alpine’s R-Series Sound System

Alpine’s R-Series line of speakers, subwoofers, and amplifiers have a heritage of sound quality that can be heard from a block away. The R-A90S is tuned to emphasize the characteristics of the R-Series speakers and subwoofers for a legendary R-Series experience.
