Description
14-Channel Hi-Res Digital Sound Processor Amplifier
The Alpine Status 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 Alpine F#1 Status DSP. The HDP-D90 contains a Crystal Oscillator Clock Generator at the core of the unit. Tracking and aligning digital information to eliminate jitter (timing errors) and accurately reproduce sound.
Alpine HDP-D90 (HI-RES AUDIO DSP AMPLIFIER)
This Alpine DSP Amplifier uses many components and technologies of the Alpine F#1 Status processor for audiophile sound quality. Input and output capabilities make the Alpine HDP-D90 super flexible. Running an internal sampling rate of 192kHz / 24bit and featuring a 14-Ch 31-band P-EQ. As well as 3-Way X- Overs, and 12-Ch digital time correction with 7mm steps adjustment.
Audiophile Sound Quality
The Alpine 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.
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.
STATUS SOUND
Active & Passive Outputs
You can use the DSP amp in passive configuration, connecting external amplifiers to the 10-channel PreOuts, or directly connect it to your vehicle’s speakers and subwoofers using the built-in 12-channel amplifier (featuring 8x 50 Watts + 4x 80 Watts @ 4 Ohm, 14,4V). You can also bridge the 80 Watt outputs to 2x 160 Watts
STATUS DSP POWERHOUSE
Matrix Input Summing
Matrix input summing allows you to combine several speaker-level channels on the input side to repurpose them in different configurations on the output side. This lets you continue to use your original radio with its fixed speaker output channels while building an entirely different amp & speaker system in your vehicle.
STATUS ULTRA-PROCESSING POWER
Purpose-built for Hi-res Audio playback, the Alpine HDP-D90 has a 192kHz/64Bit internal sampling rate and an ultra-wide audio bandwidth of 10Hz-110kHZ for recording studio-level sound.
Internal designs, like copper-plated chassis, bring the signal-to-noise ratio up to >110db and minimise noise and distortion during playback for complete music fidelity that's true to the source.
STATUS SYSTEM FLEXIBILITY
The Alpine Status HDP-D90 includes multiple source inputs for flexible system building for the option to retain a factory head unit, add an aftermarket head unit, or the Alpine Status HDS-990 Digital Media Controller. For older vehicles with no source player, the Alpine Status HDP-D90 can also function as a standalone music source and receiver for music sent directly from a smartphone with Bluetooth® wireless streaming.
High-Quality Analog Circuit
The operational amplifier is a key device for the performance and sound quality of audio analog circuits. These ICs are used throughout the circuit to process the analog signals. Ensuring uncompromised sound. Alpine sound tuning experts chose the MUSES8820, the industry's best operational amplifier.
