Alpine HDP-D90 Status 14-Channel Hi-Res Digital Sound Processor Amplifier

The Alpine Status HDP-D90 is a high-performance 14-channel digital sound processor amplifier engineered for uncompromising in-car audio. It delivers Hi-Res Audio playback up to 192kHz/24Bit, with a 192kHz/64Bit internal sampling rate and an ultra-wide 10Hz-110kHz bandwidth for studio-level fidelity.

A copper-plated chassis achieves a signal-to-noise ratio exceeding 110dB and total harmonic distortion below 0.001%, ensuring pristine, noise-free sound. With 12 amplified channels (50W x 8 plus 80W x 4 at 4 ohms) and 10 RCA pre-outs, it provides extensive system-building flexibility, while Bluetooth streaming and multiple input options allow integration with factory or aftermarket head units.
