Alpine HDP-D90

Superior Sound Performance Alpine Introduces the all-new Alpine Status sound system: using the same engineering and design concepts drawn from the third generation, Ultra High-Resolution AlpineF#1Status system, Alpine created “Alpine Status” to achieve High-Resolution Sound at a more approachable and accessible price point. The Alpine Status system is also extremely flexible: all components can be purchased and used in “stand-alone” configuration. The HDP-D90 DSP Amplifier has a 192kHz/32Bit internal sampling rate and an ultra-wide audio bandwidth of 10Hz-110kHz to reproduce sound at its intended high-resolution spec. Intentional designs, like a copper-plated chassis, bring the signal-to-noise ratio up to >110dB and minimize noise and distortion during playback. Drawing inspiration from the internal Master Clock Management System in the AlpineF#1Status DSP, the HDP-D90 contains a Crystal Oscillator Clock Generator at the core of the unit that tracks and aligns digital information to eliminate jitter (timing errors) and accurately reproduce sound. The DSP has multiple input options for flexible system building. For vehicles that are unable to replace the factory Head Unit, the DSP has 12-channels of high-level inputs that allow the factory Head Unit to be retained. The DSP amp also has an optical input to add the Alpine Status HDS-990 Media Player or analog inputs for another aftermarket Head Unit. The HDP-D90 (when used in stand-alone mode) can also receive music sent directly from a smartphone with Bluetooth wireless streaming. While the HDP-D90 has 12-channels of amplification (8x 50W x 4x 80W) and can be used to power an entire system, 10-channels of RCA output can be used to add Alpine Status amplifiers for more power or system building.
