Professional Excellence: All-in-One Audio Mastery
The P1 DSPA represents Goldhorn's entry-level powerhouse philosophy: combining high-resolution digital playback, sophisticated DSP processing, and quality amplification in a single, compact unit that eliminates complexity while maximizing performance.
DSD256 Hardware Decoding
At the heart of the P1 DSPA lies true hardware-based DSD256 (Direct Stream Digital) decoding – the same ultra-high-resolution format used for archiving master recordings. Unlike PCM-based systems that sample audio at discrete intervals, DSD captures audio as a continuous 1-bit stream at 11.2 MHz, preserving every nuance of the original performance with unmatched clarity and depth. This isn't software conversion or upsampling – it's genuine audiophile-grade playback.
ADAU1452 DSP Architecture
The P1 DSPA utilizes Analog Devices' flagship ADAU1452 SigmaDSP processor – the same professional-grade chip found in recording studios and high-end home audio systems. This powerful processor provides 10 channels of fully independent signal processing with 31-band parametric EQ on every output, precision time alignment, sophisticated crossover networks, and advanced filtering – all with floating-point precision for transparency and headroom.
Premium DAC & ADC Components
Signal integrity starts with exceptional conversion. The P1 DSPA employs Texas Instruments PCM1609 DAC (Digital-to-Analog Converter) and PCM1862 ADC (Analog-to-Digital Converter) chips – professional-grade components that deliver THD+Noise below 0.003% and signal-to-noise ratios exceeding 111 dB on digital inputs. This ensures that whether you're playing high-resolution files or processing analog signals, the sonic purity remains uncompromised.
Class AB Amplification
Unlike cheap Class D implementations, the P1 DSPA features genuine Class AB amplification delivering 4 × 65W @ 4Ω – combining the efficiency advantages of modern design with the warm, natural sound quality that audiophiles demand. The amplifier section maintains THD+Noise below 0.03% and achieves a 100 dB signal-to-noise ratio, providing clean, powerful amplification for directly driving speakers or serving as a high-quality line driver for external amplifiers.
Bluetooth 5.0 with aptX
Modern convenience meets audiophile quality with Bluetooth 5.0 featuring both aptX-LL (Low Latency) and aptX-HD codec support. While DSD256 playback via USB represents the ultimate in sound quality, Bluetooth streaming provides exceptional wireless performance – aptX-HD delivers near-CD-quality audio while aptX-LL minimizes delay to just 40ms for perfect video sync. The stable Bluetooth 5.0 connection ensures reliable streaming without dropouts or interference.
MC33078 Op-Amp Quality
Signal path integrity extends to every component. Goldhorn specifies premium Motorola MC33078 operational amplifiers throughout the P1 DSPA's analog stages – these low-noise, high-performance op-amps are legendary in professional audio for their sonic transparency and exceptional specifications. Combined with high-temperature 105°C electrolytic capacitors and WIMA film capacitors in critical locations, the P1 DSPA ensures long-term reliability even in demanding automotive environments.

All-in-One Simplicity
The P1 DSPA's integrated design eliminates the complexity and expense of assembling separate components. Instead of purchasing a standalone DSP processor, separate amplifiers, a Bluetooth receiver, and a high-resolution media player – each with their own wiring harnesses, mounting requirements, and power connections – the P1 DSPA consolidates everything into a single compact unit measuring just 180 × 140 × 36 mm.
This integration delivers multiple benefits: simplified wiring reduces installation time and potential failure points, single power connection minimizes voltage drop concerns, consolidated grounding eliminates ground loop possibilities, and the compact footprint fits in locations where multiple separate components would never fit. The gold anodized aluminum chassis provides both premium aesthetics and excellent heat dissipation for reliable long-term operation.
Flexible Input Options
The P1 DSPA accommodates virtually any source configuration through its comprehensive input complement. Eight high-level inputs (6Ω impedance, 10V sensitivity) allow direct connection to factory head units or aftermarket receivers without requiring expensive line-output converters. The intelligent EPS (Error Protection System) safeguards against mis-wiring and voltage irregularities common in factory integration scenarios.
Two stereo RCA inputs (3V sensitivity) provide traditional low-level connectivity for aftermarket source units, while the three USB 2.0 host ports enable direct playback from thumb drives or portable storage. Bluetooth 5.0 with aptX-HD adds wireless convenience, and the automatic input mixer intelligently prioritizes and switches between sources based on signal presence and user-defined preferences.
For advanced installations, the input mixer can be configured for navigation mode – allowing GPS voice prompts to automatically duck music playback without completely muting it. This seamless integration maintains functionality while preserving audio quality, a critical consideration in modern connected vehicles.
Output Configuration Flexibility
The P1 DSPA's 10-channel DSP architecture provides exceptional flexibility in system design. Six RCA pre-amp outputs (6V maximum) can drive external amplifiers for high-power applications, while the four built-in Class AB amplifier channels (65W × 4 @ 4Ω) can directly power speakers in simpler installations or serve as dedicated channels for specific applications like center channel or rear fill.
Common configuration examples include:
Entry-Level Active System: Use the built-in amplifier to drive four speakers (front tweeters and midranges), while the six RCA outputs feed an external subwoofer amplifier and potential rear speakers or signal to additional amplification.
Front-Stage Focus: Dedicate all six RCA outputs to front stage (tweeters, midranges, midbass) via external amplifiers for maximum quality, using the built-in amplifier for rear fill or a center channel application.
2.1 High-Power Setup: Use RCA outputs for high-power external amplification of front speakers and subwoofer(s), reserving the built-in amplifier for rear speakers or leaving it inactive.
Factory System Upgrade: Integrate the P1 DSPA using high-level inputs from the factory head unit, use DSP processing to correct factory speaker deficiencies, and leverage the built-in amplifier to drive upgraded speakers or add a subwoofer while retaining factory source unit functionality.
Professional Tuning Software
Goldhorn's PC-based tuning software (Windows compatible, USB Type-B connection) provides installer-grade access to every parameter within the P1 DSPA. The intuitive graphical interface displays system signal flow, visualizes EQ curves in real-time, and offers measurement-based calibration tools for objective system optimization.
The software enables advanced features like input channel copying (quickly duplicate settings across multiple channels), preset comparison (A/B different configurations to evaluate changes), and detailed measurement mode for using external RTA (Real-Time Analyzer) equipment. Installers can save customer configurations as backup files, streamlining warranty service or system updates.
For end users, the Wi-Fi mobile app (iOS and Android compatible) provides simplified access to common adjustments: volume control, preset selection, basic EQ adjustments (pre-configured curves or simple bass/treble controls), and source selection. This two-tier approach maintains professional system integrity while empowering users with appropriate control over their listening experience.
