Advanced Linear Noise Dissipation Technology

AudioQuest’s PowerQuest 303 employs cutting-edge linear noise-dissipation technology, which eliminates electromagnetic and radio-frequency interference that can degrade your sound quality. With more than -22dB of noise attenuation, this conditioner effectively filters differential-mode noise between 30kHz and 1GHz. Paired with the included PQ-415 noise-dissipating cable, featuring semi-solid concentric long-grain copper conductors and a flat-to-wall plug design, the PowerQuest 303 ensures your audio system operates in a pristine power environment.

Non-Sacrificial Surge Protection for Maximum Safety

Protect your gear with confidence, thanks to the PowerQuest 303’s non-sacrificial surge protection. Unlike traditional surge protectors that fail after a single event, the PowerQuest 303 is built to handle multiple transient power surges without sustaining damage. Whether it's micro-spike protection for short, fast blasts or catastrophic surge protection against lightning strikes, this power conditioner safeguards your equipment while maintaining its own functionality.

Automatic Shutdown for Extreme Voltage Events

In the event of a catastrophic power surge, the PowerQuest 303’s extreme-voltage automatic shutdown feature activates at 140VAC, opening the main power relay within 0.25 seconds to protect your gear. Once the incoming power stabilizes, the system automatically resets itself, ensuring your equipment remains secure even in the most unpredictable environments. This feature offers unmatched peace of mind for audiophiles and professionals alike.

Optimized Outlets and USB Charging Ports

With 12 total outlets, including 8 optimized for source components and 4 high-current outlets for amplifiers and power-hungry devices, the PowerQuest 303 ensures tailored performance for all your gear.
