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 AlpineF#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-F60 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-F60 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 83dB 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 for ultimate reliability. The HDA-F60 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.
