- Page 2 Meeting a new challenge to realize the best sound in the passenger compartment AlpineF#1Status For a quarter of a century, Alpine has been pursuing the best sound in the passenger compartment which is subject to harsh physical and electronic conditions. Alpine has developed its own unique on-board acoustic technology, which is totally differ- ent from that of home audio, in order to overcome these tough listening conditions.
- Page 3 CD Head Unit Carefully selected and fine-tuned high-precision parts to attain “best accuracy” for distortion-less reproduction of minute signals. A new high precision “DP-ST”, ensures precise retrieval of digital information and high vibration resistance. The DP-ST achieves six times greater precision than conventional CD products by incorporating accurate skew optimization along the X, Y, and Z axes.
- Page 4 Noise from various points of the circuit is restricted to the ultimate level to reproduce unprecedented “quietude” Black-finish DP/ST mechanism & copper-plated black-finish chassis for less noise effects, electric distortion, and data reading deterioration. Reflections of the laser from the CD surface can bounce into the laser reading head, causing transition errors when the digital bits change between 0 and 1 (“jitter”).
- Page 5 Unprecedented “wide dynamic range” Persistent pursuit of energetic and enjoyable “high-speed sound” Resonant DC-DC converter for stable power supply Whereas the general DC-DC converters send rectangular waves to the step-up transformer, the resonant DC-DC converter, with a simple design integrating capacitors in its Taylor circuit, sends sine waves to the step-up transformer.
- Page 6 High-precision signal transmission to maintain high quality sound information. All design factors, including contact resistance, noise effects, durability and matching, are opti- mized for the in-vehicle environment. 4V PREOUT improves the S/N ratio by cutting off noise effects and restricting ampli- fier gain The high voltage output level allows reduction of amplifier gain.
- Page 7 Advanced ergonomic design concept for “user-friendly interface” even while driving BioLite display with wide viewing angle and high resolution/contrast The high quality display uses biochemical luminescence technology that ensures outstanding visibility even in daylight. It also emphasizes advanced technology with an interactive display environment and feedback to every operation by the user.
