R-A90S
Experience your music in Hi-Res with the R-A90S 6-channel R-Series amplifier. This is one of the most versatile Class-D 6-channel amplifiers on the market, with a unique variable power channel layout that offers twice the power on the last two channels. Built-in high-pass and low-pass filters allow installation of many types of sound systems.
The new R Series speakers and subwoofers have sound quality you can hear from the ground. The new R Series amps are no exception. Apart from the best performance in this class. These amplifiers are configured to best match the tonal characteristics of the R Series speakers and subwoofers.
The Alpine R Series sound components
The speakers and amplifiers of the R Series astound with amazing levels at the same time unbelievable clarity - this makes for an absolutely fantastic sound.
They combine high output power and resilience with a broad frequency response and powerful bass. The R Series includes component and coaxial speakers, subwoofers and now, for the first time, amplifiers.
Variable power design
the 5th and 6. Channel of the R-A90S can be bridged for subwoofer operation. This means that the subwoofer system has up to 500 watts RMS at 4 ohms. The R-A90S has a unique power concept so that twice the power is available on the last two channels. This means you can set the amp to deliver 4x 75 watts + 2x 150 watts to drive 2 separate subwoofers. Or 4x 75 watts + 1x 500 watts with the appropriate power for a very powerful subwoofer.
An amplifier that grows with its tasks
Thanks to the unique variable power concept, the R-A90S can offer different frequency bands on each channel compared to conventional multi-channel amplifiers. The R-A90S can be used both as a 3-way active amplifier and as a 5-channel amplifier. This is possible because it directs the required frequencies exactly to the channels where they are needed.
Accurate sound reproduction
Hear the fine details that make your music so special. The R-A90S operates more of a very low phase shift across the entire frequency spectrum. This minimizes audible errors in playback and your content remains absolutely true to the original. With a high-resolution frequency response, the R-A90S can reproduce music and sounds incredibly accurately.
Exclusive Alpine technology
With selected Alpine components derived from Alpine's premium "X-Series" amplifier series, the R-A90S features a dual "Sierra" equalization process. This corrects the signal distortion so well that an output signal corresponds as closely as possible to the original signal as at the input.
The next step for an optimal system structure
For the best sound experience, use the built-in bandpass, highpass, or lowpass filter to power each component in your system individually and assign frequency bands for accurate and reliable sound reproduction.
Subwoofer remote control
For direct subwoofer control from the cockpit, you can connect the RUX-KNOB2 (sold separately) to the R-A90S (channel 5+6).
High flexibility and low space requirement
Compact and powerful: The new digital amplification circuit enables high output power with a small footprint. The R-A90S measures just 324mm wide x 273mm long for easy installation. The logo plate can be adjusted to install the amplifier in landscape or portrait orientation.
overheat protection
In addition to Alpine's new intelligent amplifier platform, the R Series amplifiers feature an optimal heatsink and protection circuit. This ensures reliable music playback without shutdowns.
Low & high power speaker signal inputs
The 6-channel cinch/speaker signal inputs accept low and high power signals (connection cable not included). In this way, you can connect the R-A90S directly to your original car radio, regardless of the output power of your car radio. The power terminal accepts wire up to 20 mm² (4 AWG).
