Skyatom Surround System
Version 1.1 features full Skyatom Surround support – Goldhorn's revolutionary 3D audio technology that expands the soundstage beyond physical speaker locations. Through sophisticated time alignment and phase correction algorithms, Skyatom creates a wide, spacious soundstage with precise three-dimensional imaging. Sounds are placed in exact locations with depth and realism, delivering distinct separation between instruments and vocals that transforms your vehicle into an immersive concert hall.
ADAU1450 DSP Architecture
The DSPA 810 Pro v1.1 utilizes Analog Devices' ADAU1450 SigmaDSP processor – a powerful platform delivering 10 channels of fully independent signal processing. With 31-band parametric EQ on every output channel, precision time alignment, and comprehensive crossover networks (Butterworth, Bessel, and Linkwitz-Riley topologies from 6 to 48 dB/octave), the ADAU1450 provides professional-grade processing with floating-point precision for transparency and headroom.
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 that deliver 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.
Voltage Build-Up Amplification
The DSPA 810 Pro v1.1 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.
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.
3-Way Active Crossover Ready
With 10 RCA outputs and 8 amplified channels, the DSPA 810 Pro v1.1 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.

Skyatom Surround: 3D Audio Revolution
Version 1.1's Skyatom Surround System transforms your vehicle into an immersive listening environment, creating three-dimensional soundscapes that transcend the limitations of traditional car audio.
🎭 The Science of Skyatom Surround
Goldhorn's proprietary Skyatom Surround System represents years of acoustic research specifically tailored for automotive environments. Unlike home theater systems that rely on idealized room acoustics and speaker placement, Skyatom was engineered to overcome the unique challenges of car audio – asymmetric listening positions, reflective surfaces, road noise, and limited speaker placement options.
The Skyatom algorithm analyzes incoming audio in real-time, identifying spatial cues embedded in stereo recordings. It then applies sophisticated phase manipulation, time alignment corrections, and frequency-dependent processing to create the perception of sound sources extending beyond the physical speaker locations. The result is a soundstage that stretches wider than the vehicle's cabin, with depth layers that place instruments and vocals at realistic distances from the listener.
🎯 Skyatom vs. Traditional Stereo Processing
Traditional Stereo: Sound appears to originate from speaker locations, with imaging limited to the space between left and right speakers. Off-axis listeners experience collapsed imaging and poor tonal balance.
Skyatom Surround: Sound sources appear throughout and beyond the vehicle cabin – extending left and right beyond the doors, with depth extending from the dashboard back toward rear passengers, and height cues creating overhead perception. All passengers enjoy balanced imaging and tonal accuracy regardless of seating position.
Installation & System Integration
The DSPA 810 Pro v1.1's compact form factor and comprehensive connectivity options enable flexible integration into virtually any vehicle audio system.
