Advanced Power Filtration for Enhanced Sound and PictureEngineered 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 CableThe 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 Long-Term Reliability
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 the Strongest Surges
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 for Ultimate Performance
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.

Rack-Mountable, Sleek DesignWith its compact, rack-friendly dimensions and provided 2-RU rack ears, the PQ-303 fits comfortably in most spaces.
