PowerQuest 303

AudioQuest PowerQuest 303 is a high-performance power conditioner with 12 AC outlets (4 High-Current outlets for amplifiers and 8 Linear-Filtered outlets for source components), a 2m detachable AC power cable, and 2RU rack ears for simple rack-mounting. Engineered with advanced power filtration, the PowerQuest 303 removes significantly more noise and distortion than typical power conditioners, helping your system perform at its best.

Detachable Power Cable

The detachable PQ-415 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.

Powerful Surge Defense

With non-sacrificial surge protection, the PQ-303 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-303 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.

Purpose-Built Outlets

Each of the PowerQuest 303’s outlets is specifically engineered for optimal performance in your home entertainment system. It includes:

• 4 High-Current Outlets: Designed for soundbars, power amplifiers, audio/video receivers, or subwoofers.
• 8 Linear Filtered Outlets: Ideal for audio/video source components, computers, modems, or routers.

Key Features

Linear Noise-Dissipation
Compromises Differential-Mode filtering, which addresses asymmetrical noise already present on the utility line or backwashed via electronic appliances and components.

Non-Sacrificial Surge Protection
Accepts 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 are virtually impossible. Set it and forget it.

Extreme Voltage Shutdown
At 140VAC, the main power relay opens in <0.25 seconds, resetting when power stabilizes, ensuring protection against voltage spikes for your devices.

Flat-to-Wall 45 Degree Plug
Flat-to-Wall 45 degree plug can be easily installed in tight spaces behind furniture or other hard-to-reach areas.

Catastrophic Surge Protection
Protects against lightning strikes and large-scale power surges; 2160 Joule, max. spike 6kV, 144kA.

Micro-Spike Protection
Protects against daily short, fast power spikes that damage equipment over time. Typical surge protectors can actually contribute to this sustained damage.
