AlpineF#1Status For a quarter of a century, Alpine’s goal has been the best sound in the mobile environment despite its harsh physical and electrical conditions. To overcome these severe listening conditions, Alpine has developed its own unique on-board acoustic technology.
Even the electrolyte of the electrolytic capacitor is specially ordered, a measure of the thorough considerations taken with the MRV-F900. The polarities of the parts particularly important for achieving high sound quality, such as the transformer, coils and film capacitors, are carefully controlled to achieve maximum time precision.
