Amplifier Specs:
- Massively powerful STA-2800 Class D amplifier design
- High resolution 295Mhz Analog Devices Audio DSP with double precision 56bit filtering, with over 5x the processing power of our previous subwoofers, the most advanced subwoofer processor available for perfect audio reproduction.
- DSP monitors every function of the amplifier ensuring precisely regulated clean voltage is delivered to and from the switch mode power supply and maximum current is pushed to the driver’s voice coils.
- DSP Continuously runs complex power management algorithms and multi-point thermal, voltage, and current monitoring systems to optimize AC voltage delivery to the power supply for continuous peak performance with maximum performance and greatest efficiency.
- Advanced digital audio processing and DACs (Digital-to-Analog Converters) with 120 dB Signal-to-Noise Ratio provide greater headroom, lower noise, and flawless fidelity.
- Dual-mono discrete Class D amplifiers create effortless and endless power from eight massive 60A 200V MOSFETs, resulting in lower EMI and highest efficiency while providing effortless power each voice coil, producing SPLs and low frequency output with pristine clarity well beyond reference listening levels.
- All new Switch Mode Power Supply (SMPS) includes a two-stage 100v-240v full range active Power Factor Correction (PFC) which pre-regulates mains to solid 390V DC regardless of mains voltage or quality, ensuring a consistent 160V rail voltage for the dual-mono amplifiers.
- Power-Factor-Correction (PFC) time aligns the AC voltage to the AC current resulting in less heat, greater efficiency, peak power output, and the ability to maintain rated power over a wide-range of AC voltages.
- Onboard AC line conditioner filters and stabilizes incoming voltage, corrects waveform distortions, and eliminates electromagnetic and radio interferences to optimize signal quality and audio performance.
- New convective cooling plate design pulls cool outside air through vents at the bottom of the amplifier plate, flowing over the amplifier components and internal heat sinks, eliminating the need for an external heatsinks.
- Customer EQ and DSP limiter settings specifically for the 17-Ultra allow the subwoofer to take control of a room and pressurize it with accurate, heart-pounding, acoustically tuned bass.
