Goldhorn DSPA 816 Pro
Professional Audio Processing Meets Integrated Power
The DSPA 816 Pro occupies a strategic position: premium processing without flagship pricing. Built around the automotive-qualified ADAU1452 SigmaDSP processor and PCM1690 DAC, it delivers reference-grade fidelity with efficient Class D amplification in a compact form factor.
Comprehensive input flexibility includes: 8 high-level inputs, 2 RCA inputs, optical input (192kHz/24-bit), coaxial input (192kHz/24-bit), and Bluetooth 5.0 with aptX HD. The 16-channel DSP output enables complex systems with active crossovers, center channel processing, time alignment, and dedicated subwoofer management.
Strategic Positioning in Goldhorn's Lineup
The DSPA 816 Pro sits between the DSPA 810 Pro (10-channel, 8x65W Class AB) and DSPA 1012 Plus (20-channel, 10 amps):
- vs. DSPA 810 Pro: Adds 6 DSP channels, ADAU1452 processor, Class D amplification, coaxial digital input
- vs. DSPA 1012 Plus: 80% of processing capability at $200 savings—ideal for most non-competition builds
- Luxury Integration Sweet Spot: Perfect for high-end factory integration where 16 channels suffices
At $1,099.99, it undercuts AudioControl D-6.800 ($1,200-1,300) while offering superior specifications.
ADAU1452 SigmaDSP: Automotive-Qualified Processing Power
The heart of the DSPA 816 Pro is the Analog Devices ADAU1452 SigmaDSP, an automotive-qualified audio processor that represents a significant step up from entry-level DSP chips. This processor is part of Analog Devices' premium automotive audio lineup, designed specifically to meet the demanding environmental and reliability requirements of automotive applications.
ADAU1452 Technical Advantages
The ADAU1452 operates at 294.912 MHz, providing computational headroom for complex processing without latency or artifacts.
- 48-Channel Digital I/O: Handles up to 48 channels @ 192 kHz (implements 16 outputs)
- 32-Bit Processing: Maintains signal integrity through complex processing chains
- Automotive Qualified: Tested for -40°C to +105°C operation, voltage transients, EMI
- Flexible Architecture: Four independent serial ports for expandability
PCM1690 DAC: Reference-Grade Conversion
The Texas Instruments PCM1690 DAC (24-bit/192 kHz) delivers 112 dB dynamic range, <0.001% THD+N, and multi-channel conversion without crosstalk—the same DAC architecture found in products costing significantly more.
16-Channel DSP Architecture
Extensive system design flexibility:
- 3-Way Front Stage + Rear: 6 channels tri-amped front, 2 rear, 8 remaining for subs/center/height
- Multi-Subwoofer Zones: Independent tuning per location with unique EQ/crossover/time alignment
- Center Channel: Improved imaging and vocal clarity
- Dual Listening Positions: Optimized tuning for driver and passenger
Every channel features independent 31-band parametric EQ for surgical correction of acoustic anomalies with adjustable frequency, gain, and Q factor.
Class D Amplification: Efficiency Meets Performance
The DSPA 816 Pro's integrated amplification section delivers 8 x 80W @ 4Ω using Class D topology—a deliberate engineering choice that balances power efficiency, thermal management, and audio quality. This represents a notable evolution from the Class AB amplification used in the DSPA 810 Pro, offering measurable advantages for modern automotive installations.
Class D Advantages
- Thermal Efficiency: 85-90% efficiency (vs. 60-70% Class AB), less heat, compact chassis
- Power Draw: Lower current draw reduces electrical system stress
- Compact Form Factor: 296 x 217 x 43 mm fits factory locations/under seats
- Start-Stop Compatible: Handles voltage fluctuations with built-in protection
Amplifier Performance
| Specification | Performance |
|---|---|
| Power Output | 80W RMS x 8 @ 4Ω |
| THD+N (Amplifier) | 0.02% @ 1kHz, 1W |
| Frequency Response | 20Hz - 40kHz (±0.5dB) |
| Signal-to-Noise Ratio | >100dB (A-weighted) |
| Damping Factor | >200 @ 1kHz |
| Channel Separation | >75dB @ 1kHz |
8 RCA Pre-Outputs
8 independent RCA pre-outputs @ 6V enable system expansion:
- Hybrid Amplification: Internal amps for front stage, external amps via RCA for subs/rear
- Full External: Use as pure DSP with all channels routed to external amplifiers
- Subwoofer Optimization: Dedicated high-power amps for subs, internal for full-range
The 6V output voltage (vs. 4V common in competitors) provides 50% more voltage swing, improving signal-to-noise in long cable runs.
Universal Input Architecture: Every Source, Every Scenario
The DSPA 816 Pro's input architecture demonstrates Goldhorn's understanding of real-world installation challenges. Modern automotive audio systems must integrate with an increasingly diverse array of source equipment: factory head units with proprietary digital audio protocols, aftermarket receivers with analog outputs, digital streaming devices, and wireless connectivity. The DSPA 816 Pro accommodates all of these simultaneously.
8 High-Level Inputs
8 discrete high-level inputs accept speaker-level signals (0.2V-18V) directly from factory systems with optimized input impedance to prevent fault codes.
- Automatic Sensing: Auto-detects signal presence and adjusts sensitivity
- Noise Rejection: Advanced circuitry rejects ground loop noise and EMI
- Differential Design: Maximizes noise immunity in vehicle environments
Digital Inputs
Optical input (192kHz/24-bit Toslink) for luxury factory integration (Porsche, BMW, Audi), digital streaming devices, and external processors.
Coaxial input (192kHz/24-bit RCA) offers longer cable runs (10m+ vs. 5m optical), mechanical robustness, and alternative source compatibility. Having BOTH inputs is rare in this price category.
Bluetooth 5.0
Bluetooth 5.0 module (aptX HD, aptX, AAC, SBC):
- aptX HD: 24-bit/48kHz near-lossless for Android
- AAC Optimized: High-quality iOS device support
- Extended Range: 10m line-of-sight, multi-device stability
- External Antenna: Optimal placement for RF-shielded locations
USB-B PC Connection
USB-B port for PC software configuration, tuning, firmware updates, and real-time monitoring during installation.
Professional Signal Processing Tools
The DSPA 816 Pro's signal processing capabilities go far beyond basic equalization and crossover functions. Goldhorn has implemented a comprehensive suite of tools that enable professional-level system tuning and acoustic optimization.
31-Band Parametric EQ
Per Channel: Every output channel features independent 31-band parametric EQ with adjustable frequency (20Hz-20kHz), gain (±12dB), and Q factor (0.5-16).
Application: Surgical correction of speaker response irregularities, cabin acoustic anomalies, and installation-specific resonances.
Active Crossovers
Filter Types: Butterworth, Bessel, Linkwitz-Riley topologies with slopes from 6dB/octave to 48dB/octave.
Flexibility: Independent high-pass and low-pass filters on every channel enable complex multi-way active designs.
Time Alignment (0-20ms)
Precision: Adjust signal delay in 0.1ms increments (equivalent to ~3.4cm of acoustic path difference).
Application: Compensate for driver distance differences, align wavefronts from multiple speakers, create coherent soundstage imaging.
Phase Adjustment
Range: 0-180° phase rotation per channel for optimizing driver integration and managing acoustic interference.
Application: Critical for subwoofer integration and multi-driver arrays where phase alignment affects overall system response.
Input Mixing & Routing
Flexibility: Route any input to any output with adjustable mixing ratios, enabling complex signal distribution scenarios.
Application: Combine multiple sources, create aux-in feeds, implement upmixing from stereo to multi-channel.
8 Memory Presets
Instant Recall: Store complete system configurations and recall them instantly via software or optional remote control.
Application: Save different tuning profiles for various music genres, listening modes, or passenger configurations.
Output Level Control
Range: Independent level adjustment for each channel (-60dB to 0dB) with 0.1dB precision.
Application: Balance system levels, compensate for speaker sensitivity differences, adjust subwoofer integration.
EPS Error Protection
Monitoring: Real-time monitoring of amplifier temperature, voltage levels, and output signals with automatic protection engagement.
Protection: Thermal shutdown, over-voltage protection, DC offset detection, short-circuit protection.
Competitive Analysis: Value in the $1,000-1,300 DSP/Amp Category
The $1,000-1,300 price range for integrated DSP amplifiers is highly competitive, with offerings from established brands like AudioControl, Mosconi, Helix, and JL Audio. The DSPA 816 Pro's positioning in this market segment is strategic: it delivers premium specifications at a price point that undercuts most competitors while avoiding the compromises typical of budget-oriented products.
