AudioQuest PowerQuest 909 20-Amp Power Conditioner with Non-Sacrificial Surge Protection

  • Differential- and Common-Mode Ultra-Linear Filtering: Ensures consistent, wide-bandwidth noise reduction for black backgrounds and detailed, nuanced sound.
  • Transient Power Correction (TPC):
Low-impedance circuit provides current-starved amplification components with a reservoir of 45 amps (peak, up to 25ms) for uncompressed current on demand, enabling thrilling dynamic contrasts, bass impact, and control.
  • Non-Sacrificial Surge Protection:
Withstands multiple transient power surges and spikes up to 6000V or 3000A (the maximum that can make it through a home or office electrical panel). Damage from electrical storms or power-line interruptions is virtually impossible. Set it and forget it.
  • Extreme Voltage Shutdown: 140V AC activates main circuit relay in under 0.25 seconds and automatically resets once incoming voltage is within a safe range.
  • 12 Hospital-Grade AC outlets (4 High-Current w/ TPC for power amplifiers, powered speakers and subwoofers; 8 Ultra-Linear Filtered for source components): Provide superior retention strength; optimized for connected device.
  • Detachable Power Cable Included: 2m PQ-920 detachable power cable features Semi-Solid Concentric Perfect-Surface Copper+ (PSC+) and Long-Grain Copper conductors; ZERO-Tech (No Characteristic Impedance) for uncompressed current transfer; RF/ND-Tech, which minimizes circuit misbehavior by cancelling induced RF noise; and a flat-to-wall plug to aid installation in tight places. 12AWG | 20A RMS capacity; NEMA male wall plug and IEC C-19 female connector.
  • Rack-Mountable: Includes 2-RU rack-mounting kit for simple, secure installations.
