About The Product
Superior Sound
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.
Impressive Output
Powering a Hi-Res sound system without contributing noise during playback requires efficiency and precision and the HDA-M80 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.
Precise Sound Reproduction
The HDA-M80 features a high-efficiency digital circuit design that ensures ultra-low distortion levels for precise sound reproduction and superb sound quality. Intentional designs, like 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.
