16 Channel DSP/DSD Player with 8x80w Amplifier
All-in-One: DSP + Hi-Res DSD Player + 8-Channel Amplifier | Plug & Play Installation
All-in-One Solution
$1,599.99
DSP + DSD Player + 8x80W Amp | Replaces $3,000+ Separate Components
The Ultimate All-in-One Audio Integration Solution
The Goldhorn P2 DSPA Pro revolutionizes car audio integration by combining three essential components in a single, beautifully engineered chassis: a 16-channel digital signal processor, a hi-resolution DSD music player, and a powerful 8-channel Class D amplifier (8x 80W @ 4Ω = 640W total). This isn't just convenience—it's a fundamental reimagining of system architecture that eliminates complexity, reduces installation time, and delivers professional-grade audio performance at a fraction of traditional multi-component costs.
Built around the ADAU1452 DSP processor (Analog Devices' flagship automotive audio chip), the TI PCM1690 24-bit/192kHz DAC, and an efficient Class D amplifier section, the P2 DSPA Pro provides 16 total output channels: 8 amplified speaker outputs (80W each) plus 8 RCA pre-outs (6Vrms) for external amplifier connections. This dual-output architecture enables unprecedented flexibility—drive smaller speakers directly from internal amplification while connecting high-power external amps for subwoofers and premium components.
What truly distinguishes the P2 DSPA Pro is its integrated DSD Hi-Res music player with native DSD256 support—a feature rarely found in car audio, typically reserved for $5,000+ home audiophile equipment. Connect up to three USB drives simultaneously (USB 2.0 Host), and access your entire DSD, WAV, FLAC, APE, AIFF, and MP3/AAC music library with bit-perfect playback. The built-in Bluetooth 5.0 module (aptX-LL/aptX-HD) adds convenience for wireless streaming without compromising system capabilities.
Why P2 DSPA Pro? At $1,599, it costs $400-$600 less than competitors (Helix V EIGHT DSP MK2: $1,600; Audison BitOne.1 HD + external amp: $2,200+) while delivering more DSP channels (16 vs 10-13), integrated DSD playback (competitors lack player modules), and plug-and-play installation via 8 high-level inputs (no wire cutting, no LOC converters). The distinctive red anodized aluminum finish isn't just aesthetically striking—it's functional, providing superior heat dissipation for the integrated Class D amplifier section.

DSD Hi-Res Player: Audiophile-Grade Features
🎵 What is DSD? (Direct Stream Digital)
DSD (Direct Stream Digital) is a high-resolution audio format originally developed by Sony and Philips for Super Audio CD (SACD). Unlike PCM (Pulse Code Modulation) used in CDs and most digital audio, DSD uses 1-bit delta-sigma modulation at extremely high sampling rates—creating a digital representation that more closely resembles the original analog waveform.
DSD Sampling Rates:
- DSD64: 2.8224 MHz (64x CD sampling rate) — equivalent to SACD quality
- DSD128: 5.6448 MHz (128x CD) — double DSD, studio mastering quality
- DSD256: 11.2896 MHz (256x CD) — ultra-high-res, archival quality
Why DSD matters for audiophiles: Many listeners describe DSD as having a more "analog-like" smoothness compared to PCM. The P2 DSPA Pro's native DSD256 support means you can play the highest-quality DSD files without PCM conversion—preserving the format's inherent sonic characteristics.
💾 Triple USB Host: Music Library Management
The P2 DSPA Pro includes three USB 2.0 Host ports—enabling unprecedented flexibility for music library organization and access:
- Front USB port: Easily accessible for temporary files, new music additions
- Rear USB port: Permanent installation for main music library (hide cable routing)
- Trunk/cargo USB port: Large-capacity drive for extensive DSD/FLAC collections
Organizational strategies:
- By genre: USB1 (Rock/Pop), USB2 (Jazz/Classical), USB3 (Electronic/Hip-Hop)
- By format: USB1 (DSD files), USB2 (FLAC/WAV), USB3 (MP3/AAC playlists)
- By mood: USB1 (Energetic driving music), USB2 (Relaxed cruising), USB3 (Audiophile test tracks)
Supported storage: USB flash drives, portable SSDs, USB hard drives (FAT32/exFAT formatted). Maximum tested capacity: 2TB per port (6TB total across three ports).
🎶 Comprehensive Format Support
The P2 DSPA Pro supports virtually every music file format used by audiophiles and casual listeners:
Playback tip: For best sonic results, use DSD files for acoustic/jazz recordings (smoother highs, analog-like presentation) and 24-bit/192kHz FLAC for rock/electronic (precise transients, dynamic punch).
📶 Bluetooth 5.0: aptX-HD Wireless Quality
While USB/DSD playback provides ultimate audio quality, the P2 DSPA Pro's Bluetooth 5.0 module with aptX-HD and aptX Low Latency ensures wireless streaming doesn't compromise system performance:
- aptX-HD: 24-bit/48kHz wireless transmission (576 kbps) — near-lossless quality for streaming services (Tidal HiFi, Qobuz, Apple Music Lossless via iPhone)
- aptX Low Latency: <40ms audio delay — eliminates lip-sync issues when watching videos or using navigation
- AAC/SBC fallback: Ensures compatibility with all Bluetooth devices (iPhone, Android, laptops)
- Bluetooth 5.0: Extended range (~30 meters vs 10m BT 4.2), improved stability in electrically noisy car environments
Practical use: Use Bluetooth for casual listening, podcasts, navigation audio, and switch to USB/DSD playback for critical listening sessions—the P2 DSPA Pro's input mixer allows seamless transitions without manually switching sources.
