Dirty power can have a negative impact — both on you and your gear. The AudioQuest PowerQuest 303 offers a comprehensive solution. This 12-outlet power conditioner boasts linear noise dissipation, safeguarding you against unwanted electromagnetic and radio-frequency interference. The PowerQuest 303 also includes non-sacrificial surge protection, enabling you to keep your gear safe from power spikes without damaging the unit itself. You also get extreme voltage shutdown to bail you out of catastrophic situations. The PowerQuest 303 sports optimized outlets for your source components and high-current devices, along with a noise-dissipating cable with a flat-to-wall plug and rack ears for rackmounting. You've invested a lot in your gear; give it the protection it deserves with the AudioQuest PowerQuest 303.

Industrial-strength sanitation for your power

Electromagnetic interference, radio-frequency interference, and other AC-fueled gremlins will wreak havoc on your gear. But there's an antidote: AudioQuest's linear noise-dissipation technology. This revolutionary system is at the heart of the PowerQuest 303, providing you with more than -22dB of noise attenuation with differential-mode filtering between 30kHz and 1GHz. Moreover, the PowerQuest 303 comes with a PQ-415 RF-noise-dissipating cable with semi-solid concentric long-grain copper conductors and a convenient flat-to-wall plug. If you're sick and tired of dealing with noisy AC power, the PowerQuest 303 offers a truly effective solution.

Non-sacrificial surge protection

Errant power spikes can spell doom for your sensitive electronic equipment. That's why the engineers here at Sweetwater would never dream of operating our high-dollar gear without a rock-solid surge-protection device like the AudioQuest PowerQuest 303. This outstanding 12-outlet power conditioner safeguards against the full gamut of surges, equipping you with micro-spike protection against short, fast blasts as well as catastrophic surge protection against lightning strikes and large-scale power surges. Best of all, the PowerQuest 303 offers non-sacrificial surge protection, which allows it to withstand multiple transient power surges and spikes without sustaining damage.

Extreme-voltage automatic shutdown

If you ever find yourself face-to-face with a true cataclysmic power event, the PowerQuest 303 will be ready. Its extreme-voltage automatic shutdown feature deploys at 140VAC, opening the main power relay within 0.25 seconds and then automatically resetting when the incoming power stabilizes. No matter what type of power environment you're working in, the PowerQuest 303's automatic shutdown feature offers the utmost peace of mind.
