About This

• 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.
• 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 copper-plated chassis and other features bring the signal-to-noise ratio to >110dB.
• 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.
