Amplifier Specs:
Sledge STA-2800D with 2800 watts RMS continuous power (6000+ watts peak dynamic power)
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.
