Goldhorn DSPA 810 Pro: 10-Channel DSP & Amplifier v1.0
Professionally Maintained Demo Units
Every demo unit has been carefully maintained by our certified technicians. These aren't customer returns or damaged goods - they're the same high-quality equipment we've used to demonstrate premium sound to our customers for years.
Pre-Tested & Verified
Unlike typical clearance sales, every item has been tested and verified by our technical team. We stand behind the quality of our relocation inventory.
Everything Must Go Pricing
These aren't regular sale prices - this is genuine "moving warehouse" pricing. Discounts you simply won't find under normal retail circumstances.
Trade Show Display Models
Many items are pristine display models from major audio trade shows - equipment that's been seen but never installed. These pieces often include special editions or limited releases not available through regular retail channels.
Goldhorn DSPA 810 Pro v1.0
10-Channel DSP & Amplifier • Standard Edition
Professional 3-Way Active Processing with Built-In Class AB Amplification
Factory Sealed • Limited Remaining Stock • Replaced by v1.1
🔍 Version 1.0 vs Version 1.1: Understanding the Difference
The DSPA 810 Pro v1.0 (Standard Edition) is the original discontinued model that has been replaced by the v1.1 in Goldhorn's current product lineup.
The ONLY difference: Version 1.0 does NOT include Skyatom Surround 3D audio processing. Version 1.1 adds this feature. Everything else is identical — same ADAU1450 DSP chip, same 8×65W Class AB amplification, same 31-band parametric EQ, same crossover capabilities, same time alignment, same Texas Instruments conversion components.
✅ If you don't need Skyatom Surround 3D processing, the v1.0 delivers identical core DSP and amplification performance at exceptional value with limited remaining factory-sealed stock.
✨ BRAND NEW FACTORY SEALED — NOT Display or Demo
These are brand new, unopened, factory-sealed units — never used as display models or demos. While the v1.0 has been discontinued and replaced by v1.1, we have limited remaining new-in-box inventory available at exceptional pricing. Each unit includes original packaging, all factory accessories, and represents uncompromised value for enthusiasts seeking professional DSP capabilities without the Skyatom Surround feature.

Professional Excellence: Core Features
1 ADAU1450 DSP Architecture
The DSPA 810 Pro v1.0 utilizes Analog Devices' ADAU1450 SigmaDSP processor — a powerful 295 MHz SHARC core platform delivering 10 channels of fully independent signal processing. With 31-band parametric EQ on every output channel, precision time alignment (0-20ms, 0.02ms resolution), and comprehensive crossover networks (Butterworth, Bessel, and Linkwitz-Riley topologies from 6 to 48 dB/octave), the ADAU1450 provides professional-grade processing with 32-bit floating-point precision for transparency and headroom.
The same DSP chip powering professional studio processors and high-end home audio equipment — now in your vehicle.
2 Premium Conversion Components
Signal integrity starts with exceptional conversion. The DSPA 810 Pro employs Texas Instruments PCM1690 + PCM1754 DAC chips and dual PCM1840 ADC chips — professional-grade components delivering THD+Noise below 0.003% on RCA outputs and signal-to-noise ratios exceeding 105 dB. Combined with premium Motorola MC33078 operational amplifiers and high-temperature 105°C electrolytics with WIMA film capacitors, the 810 Pro ensures sonic purity across all signal paths.
24-bit/192 kHz conversion capability preserves every nuance of the original recording with studio-monitor transparency.
3 Voltage Build-Up Amplification
The DSPA 810 Pro v1.0 features Goldhorn's voltage build-up technology in its Class AB amplifier section delivering 8×65W @ 4Ω with exceptional consistency and reliability. This advanced power supply design maintains stable voltage rails even under demanding loads, ensuring clean amplification with THD+Noise below 0.03% and a 100 dB signal-to-noise ratio. The Class AB topology combines efficiency with warm, natural sound quality that audiophiles demand.
Class AB's sonic superiority over Class D — linear response, low distortion, and effortless dynamic capability without switching artifacts.
4 Bluetooth 5.0 with aptX HD
Modern convenience meets audiophile quality with Bluetooth 5.0 featuring aptX HD, aptX, AAC, and SBC codec support. The aptX HD codec delivers 24-bit/48 kHz audio quality wirelessly — approaching CD quality with the convenience of smartphone streaming. The stable Bluetooth 5.0 connection provides extended range and freedom from interference, while multiple codec support ensures compatibility with any source device for exceptional wireless performance.
No compromises — stream high-resolution audio wirelessly without the sonic degradation of standard Bluetooth.
5 3-Way Active Crossover Ready
With 10 RCA outputs and 8 amplified channels, the DSPA 810 Pro v1.0 excels at 3-way active crossover configurations. Dedicate separate channels to tweeters, midranges, and woofers for optimal driver control and performance. The comprehensive crossover options (variable slopes, phase rotation 0-359°, and independent time alignment per channel) enable precise driver integration that passive crossovers simply cannot achieve — delivering superior imaging, clarity, and dynamic range.
Active crossovers unlock 3-6 dB of additional efficiency and eliminate passive component losses for maximum driver potential.
6 Precision Time Alignment
Achieve pinpoint sound imaging with independent time alignment on each of the 10 output channels. The DSPA 810 Pro offers 0-20ms of delay per channel with 0.02ms resolution — allowing you to compensate for asymmetric speaker placement and create a perfectly focused soundstage. Combined with 0-359° phase control per channel, you can achieve phase-coherent driver integration across all crossover points for seamless frequency transitions.
Time alignment is the difference between "speakers in a car" and "sitting in the recording studio" — 0.02ms resolution equals sub-millimeter positioning accuracy.

💡 Why This Matters: The Audiophile Perspective
The Active Crossover Advantage
Passive crossovers waste 20-40% of amplifier power as heat through resistors, inductors, and capacitors. Active crossovers eliminate these losses, delivering 3-6 dB more efficiency — equivalent to doubling amplifier power. More critically, active crossovers enable independent driver optimization with precise frequency, phase, and time alignment control that passive networks cannot match. The result: superior imaging, increased dynamic range, and seamless driver integration.
Time Alignment: The Forgotten Dimension
In vehicles, speakers are never equidistant from the listener. A tweeter in the A-pillar might be 24" away while the midbass in the door is 36" distant. These 12" cause the tweeter's output to arrive 0.88ms earlier — enough to destroy imaging coherence. The 810 Pro's 0.02ms time alignment resolution corrects this phase shift, creating a perfectly focused soundstage as if all drivers were equidistant. This is why every serious SQ competitor uses DSP time alignment.
Component Quality: Texas Instruments vs Generic
The PCM1690/PCM1754 DACs and PCM1840 ADCs deliver THD+N below 0.003% with >105 dB signal-to-noise ratios — specifications matching professional studio equipment. Generic converters found in budget DSPs suffer 0.05-0.1% THD and 80-90 dB S/N ratios, introducing audible harshness and reduced dynamic range. Combined with Motorola MC33078 op-amps (revered in audiophile circles for low-noise, high-linearity performance), the 810 Pro's signal path rivals standalone audiophile DACs costing thousands.
Version 1.0 Value Proposition
The v1.0's discontinued status and lack of Skyatom Surround processing creates exceptional value for purists focused on stereo accuracy rather than surround effects. Skyatom Surround is a spatial audio enhancement feature — impressive for casual listening but often disabled by serious audiophiles and SQ competitors seeking reference-grade stereo imaging. With identical DSP processing, amplification, and conversion components, the v1.0 delivers 100% of the core performance at significantly reduced pricing. For enthusiasts prioritizing transparent, accurate reproduction over spatial effects, the v1.0 represents uncompromised value.
