Digital Designs SS9000 Full Bridge Hybrid Digital Competition Series Monoblock Amplifier

Description

The DD Audio SS9000 is a compact, high-power, full-range Class D monoblock car audio amplifier manufactured by Digital Designs (DD Audio). Key Specifications & Power Output • Type: Full-bridge hybrid monoblock amplifier • RMS Power Output (at 14.4V test voltage): • 3,000 Watts RMS at 4 Ohms • 6,000 Watts RMS at 2 Ohms • 9,000 Watts RMS at 1 Ohm • Power Supply: Six-pack (sextuple) toroidal transformer design with oversized capacitors • Frequency Response: 20 Hz – 20 kHz (full-range capability for subwoofers or pro-audio speaker/stunt walls) • Crossover Filters: • Sub-Sonic Filter: 20 Hz – 80 Hz (12 dB/Oct) • Low-Pass Filter: 80 Hz – 20 kHz (12 dB/Oct) • Signal-to-Noise Ratio (S/N): >95 dB • Total Harmonic Distortion (THD): <1.0% • Max Current Draw: 900 Amps • Wire Gauges: Dual 0 AWG power terminals and 4 AWG speaker terminals • Dimensions: 15.7" × 7.3" × 2.4" (398 × 185 × 60 mm) Design Highlights • Hybrid Architecture: Combines full-bridge efficiency with high-current devices typically found in half-bridge amps, lowering the noise floor and improving high-frequency speed. • Compact Footprint: Engineered to pack 9,000 watts into a dense, heavy-duty aluminum chassis featuring thick sidewalls and extended heatsink fins. • Power Requirements: Due to the extreme power density, short runs of pure Oxygen-Free Copper (OFC) power cabling are strongly recommended over Copper-Clad Aluminum (CCA).
