Professional Excellence: Core Features
The DSPA 810 Pro v1.0 combines Goldhorn's refined DSP architecture with powerful Class AB amplification – delivering exceptional 3-way active crossover capabilities in a compact, value-driven package.
ADAU1450 DSP Architecture
The DSPA 810 Pro v1.0 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 v1.0 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.
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 v1.0 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.
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.
