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.
