PowerQuest® 303 12-Outlet Power Conditioner & Non-Sacrificial Surge Protector

Advanced Power Filtration for Enhanced Sound and Picture

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.

High-Performance, Detachable Power Cable

The detachable PQ-415 cable features AudioQuest’s high-purity Semi-Solid Long-Grain Copper conductor metal. The strands are tightly packed and fixed in place, significantly reducing strand-interaction distortion. Long-Grain Copper further minimizes distortion caused by grain boundaries present in all metal conductors.

A key part of AudioQuest’s Noise-Dissipation technology, Direction-Controlled Conductors ensure induced noise is dissipated and drained away from your system’s sensitive circuitry.

Powerful Surge Defense with Long-Term Reliability

With non-sacrificial surge protection, the PQ-303 goes beyond traditional surge protectors. It shields your equipment from high voltage and current surges, ensuring long-term device reliability.

The Extreme Voltage Shutdown feature activates the main power relay in less than 0.25 seconds at 140VAC and resets automatically once power stabilizes.

Built to Withstand the Strongest Surges

The PQ-303 endures rigorous 6000V/3000A input surge tests, surviving multiple surges at the highest levels a building’s AC panel can deliver. It offers reliable protection without components degrading over time.

Purpose-Built Outlets for Ultimate Performance

Each outlet is designed for optimal home entertainment performance:

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

Rack-Mountable, Sleek Design

Compact and rack-friendly, the PQ-303 includes 2RU rack ears for easy installation in most spaces.
