Alpine

Using expertise gleaned from over five decades of crafting premium car audio products and trickle-down engineering and design from the Ultra Hi-Res Alpine-F#1Status system technologies, the Alpine Status-System features exceptional tooling and rich build quality for the best possible sound reproduction. Each component was hand-picked from the highest-quality materials for the highest in-class audio performance, that when used as a complete system, can achieve 192kHz/24Bit playback. Powering a Hi-Res sound system without contributing noise during playback requires efficiency and precision and the HDA-V90 was intentionally designed to provide impressive power output to the system while ensuring the purest audio performance. The amplifier’s wide dynamic range capability provides impressive output in a compact chassis that fits most vehicle applications. The HDA-V90 features a high-efficiency digital circuit design that ensures ultra- low distortion levels for precise sound reproduction and superb sound quality. Intentional designs, like a copper-plated chassis and black circuit board, bring the signal-to-noise ratio up to 87dB and minimize noise and distortion during playback for complete music fidelity that’s true to the original source. Featuring technology unique to Alpine, the amplifier features Alpine’s dual negative feedback control circuit to improve linearity for the most accurate sound amplification. This technology also stabilizes the amplifier output while driving the speakers and subwoofers for ultimate reliability. The HDA-V90 features Alpine’s quick- connect power and speaker connectors for quick and safe installation. The one- sided terminal layout and top-panel sound controls give the user quick access to controls on the amplifier. The Alpine Status System is sold separately and can be used to build a custom sound system. Three sets of true 4V preamp outputs are included to add additional amplifiers if more power is needed. For best results, install the complete Alpine Status system together as a full system to achieve the highest in-class audio performance only second to the Ultra High-Resolution AlpineF#1System.

The R-A90S has a unique staggered power channel layout that has double the power on the last two channels. When looking to power a dual subwoofer configuration, the R-A90S’s 5th and 6th channels can be bridged to provide up to 500-watts at 4Ω. The R-A90S is matched in power and performance for the Dual 10-inch Alpine Halo S-Series Preloaded Subwoofer Enclosures with ProLink™. Thanks to the unique staggered power channel layout, the R-A90S can host different levels of power on each channel, compared to traditional, multi-channel amplifiers. This allows the R-A90S to grow with you as it can 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.  Hear the subtle details you’ve been missing in your music. The R-A90S maintains an extremely low phase shift throughout the music spectrum, which minimizes audible imperfections in your music and allows your music to stay faithful to the original recording. With a hi-resolution frequency response, the R- A90S can reproduce sound with incredible accuracy that stays true to the artist’s intention. Using custom Alpine internal components originally launched in Alpine’s premium X-Series amplifiers, the R-A90S has dual post-filter feedback loops that correct signal distortion by making the output as close as possible to the original input for accurate sound reproduction. 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. 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. 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. Features 6-Channel Amp with 5-Channel Power– With double the power on the last two channels, the R-A90S’s 5th and 6th channels can be bridged to provide up to 500-watts at 4Ω to a subwoofer system such as a pair of S-SB12Vs. An Amp that Grows with You – When you’re ready to upgrade your Alpine system, use the R-A90S to amplify a 3-way active system with enough mid-bass power to create the up-front bass impact you crave. Accurate Sound Reproduction – With incredibly low phase shift and hi-resolution frequency response, the R-A90S can reproduce sound with incredible accuracy that stays true to the artist’s intention.  Specifications Dimensions: 12.75" x 10.75" x 2" Hi-Resolution Audio Compliant (40k Hz)  Alpine’s Class D Amplifier Circuit  75W x 4 + 150W x 2 (4Ω, 14.4V, < 1% THD +N)  100W x 4 + 250W x 2 (2Ω, 14.4V, < 1% THD +N)  Bridged: 200W x 2 + 500W x 1 (4Ω, 14.4V, < 1% THD +N)  S/N > 85dB (ref. 1W into 4Ω)  THD + N < 0.03% (ref. 10W into 4Ω)  Frequency response: 10-45kHz (0/-3dB) Damping factor > 500 CTA-2006 Alpine R-A90S Manual
