The PowerQuest 505 is a high-performance power conditioner with non-sacrificial surge protection and ultra-linear filtering. The PQ-505's 12 AC outlets have been optimized for the connected devices (4 High-Current outlets for amplifiers and 8 Linear-Filtered outlets for source components). Differential and common-mode filtering contribute to an ultra-low noisefloor and black backgrounds for surprising clarity and impact. Adding to its class-leading performance and versatility, the PQ-505 comes with a high-performance AudioQuest-designed 2m AC power cable and 2RU rack-mounting kit.

Features

  • Differential- and Common-Mode Ultra-Linear Filtering: Ensures consistent, wide-bandwidth noise reduction for black backgrounds and detailed, nuanced sound.
  • 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 AC outlets: 4 High-Current for power amplifiers, powered speakers and subwoofers; 8 Linear-Filtered for source components.
  • Detachable Power Cable Included: The PQ-715 cable uses high-purity Semi-Solid 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.
  • Rack-Mountable: Includes 2-RU rack-mounting kit for simple, secure installations.

Detachable Power Cable

The detachable PQ-715 cable uses AudioQuest’s high-purity Semi-Solid Long-Grain Copper conductor metal in which strands are packed more tightly and never change position within the bundle, significantly reducing strand-interaction distortion. Long-Grain Copper further minimizes distortion caused by grain boundaries that exist within any metal conductor.

A fundamental aspect of AudioQuest's multifaceted Noise-Dissipation technology, Direction-Controlled Conductors ensure induced noise is dissipated and drained properly — away from the system’s vulnerable circuitry. AudioQuest’s ZERO-Tech ensures uncompressed current transfer and linearized noise-dissipation; RF/ND-Tech minimizes circuit misbehavior by canceling induced RF noise.

Powerful Surge Defense

With non-sacrificial surge protection, the PQ-505 goes beyond traditional surge protectors. It safeguards against high voltage and current, preventing damage to your equipment and ensuring the device’s long-term reliability. The Extreme Voltage Shutdown feature activates the main power circuit relay in less than 0.25 seconds at 140VAC and automatically resets once power returns to a safe level.

Built to Withstand

Built to endure rigorous 6000V/3000A input surge tests, the PQ-505 can withstand multiple surges at the highest level that a building’s AC panel can survive, offering reliable protection without components wearing out over time.
