HI-RES AUDIO DSP AMPLIFIER
The Alpine Status system features many technologies, components, and materials of the AlpineF#1Status system to achieve ultra high-precision music reproduction - at an affordable price tag. High-Res Audio playback of 192kHz / 24bit allows Alpine Status to create a heightened listening experience in the vehicle that emulates the feeling of an intimate recording studio session.
This DSP amplifier uses many components and technologies of the AlpineF#1Status processor for audiophile sound quality and is very flexible with tons of different input and output capabilities. It runs an internal sampling rate of 192kHz / 24bit and features a 14-Ch 31-band P-EQ, 3-Way X- Overs, and 12-Ch digital time correction with 7mm steps adjustment.
The HDP-D90 features an ultra-wide Hi-Res Audio bandwidth of 10Hz to 110kHz. Very low phase shift and distortion ensure high-quality static performance and great imaging. The cop-per-plated chassis and other features bring the signal-to-noise ratio to >110dB.
Each digital component processes digital signals using a different clock (timing), which causes slight signal misalignment, known as jitter when transmitting the audio data. This jitter distortion results in a decreased feeling of realism in the music. In the case of 192kHz/24bit audio, even a slight amount of jitter is a factor that cannot be overlooked. This means that a high degree of precision is required between the Head Unit, which sends the digital music data, and the DSP Amplifier, which receives the data and performs the sound tuning. The Alpine Status system uses an extremely high precision clock, having the same high specifications as top-grade home audio components, for both the Head Unit and the DSP Amplifier, ensuring the most compatible and accurate data transmission.
