It was built for light bulbs and motors, not for today’s audio and video gear. Modern noise from WiFi, dimmer switches, and LED bulbs makes it worse — yours and your neighbors’.\u003c\/p\u003e\n\u003cp\u003eAudioQuest has measured what this does. Up to a third of a high-resolution audio signal can be lost or covered up by AC noise before it reaches your speakers. Once that detail is gone, it’s gone for good.\u003c\/p\u003e\n\u003cp\u003eIn our experience, a good power conditioner will almost always noticeably improve the sound of any high-end audio system.\u003c\/p\u003e\n\u003cp\u003eThe PowerQuest 2 is AudioQuest’s 6-outlet entry into real power conditioning. It’s a slim unit, easy to install, with a dedicated outlet optimized for 4K and 8K video, Non-Sacrificial Surge Protection, and the same Extreme Voltage Shutdown found on the higher-end PowerQuest rack-mount conditioners.\u003c\/p\u003e\n\u003ch3\u003eDifferential-Mode Noise-Dissipation\u003c\/h3\u003e\n\u003cp\u003eThe PQ-2 provides more than 22 dB of noise reduction across a wide 30 kHz – 1 GHz bandwidth in differential mode.\u003c\/p\u003e\n\u003cp\u003eThe filter is linearized for dynamic line impedance, from 0.05 Ohms (source) to 10–50 Ohm load. That means even filtering across the whole range — not a sharp peak at one frequency that leaves nearby bands open.\u003c\/p\u003e\n\u003ch3\u003eNon-Sacrificial Surge Protection + Extreme Voltage Shutdown\u003c\/h3\u003e\n\u003cp\u003eMost surge protectors are “sacrificial” — they work once. After a big surge, the parts inside are used up and the unit stops protecting your gear, even though it still passes power.\u003c\/p\u003e\n\u003cp\u003eThe PQ-2 doesn’t work that way. It’s rated to withstand repeated 6,000V \/ 3,000A surges — the most that can pass through a home’s electrical panel — without wearing out.\u003c\/p\u003e\n\u003cp\u003eExtreme Voltage Shutdown adds a second layer of safety. If incoming voltage goes above 140VAC, the main relay opens in under a quarter of a second. It resets on its own once power is safe.\u003c\/p\u003e\n\u003ch3\u003eSix Outlets, Including a Dedicated 4K\/8K Video-Optimized Outlet\u003c\/h3\u003e\n\u003cp\u003eFour Linear-Filtered outlets serve your DACs, streamers, preamps, CD players, and other source\/networking gear. One High-Current outlet is engineered for your soundbar, AV receiver, or powered subwoofer. One 4K\/8K Video-Optimized outlet adds extra noise-dissipation technology specifically tuned for high-resolution video components — use it for your TV, projector, or 4K\/8K player.\u003c\/p\u003e\n\u003ch3\u003eDesigned to Hide\u003c\/h3\u003e\n\u003cp\u003eThe PQ-2 has a slim profile and a rugged floor-mounting stand, ideal for mounting behind cabinets. Power cords plug straight down to the top-layer outlets, keeping installations clean. The stand is detachable if you’d rather shelf-mount.\u003c\/p\u003e\n\u003cp\u003eAlso included: two USB charging ports (3.4A total), signal-line protection for cable\/satellite TV, and a 7-foot AudioQuest power cord. AudioQuest’s Connected Equipment Protection Warranty is included.\u003c\/p\u003e\n\u003c!-- WHO IS THIS BEST FOR --\u003e\n\u003ch2\u003eWho Is This Product Best For?\u003c\/h2\u003e\n\u003cp\u003e\u003cimg class=\"emoji\" role=\"img\" draggable=\"false\" src=\"https:\/\/s.w.org\/images\/core\/emoji\/17.0.2\/svg\/2714.svg\" alt=\"✔️\" width=\"15\"\u003e You have a compact system — a TV setup, gaming rig, desktop audio, or small two-channel room — and you want real AudioQuest power protection without going to a rack-mount unit.\u003c\/p\u003e\n\u003cp\u003e\u003cimg class=\"emoji\" role=\"img\" draggable=\"false\" src=\"https:\/\/s.w.org\/images\/core\/emoji\/17.0.2\/svg\/2714.svg\" alt=\"✔️\" width=\"15\"\u003e You own a 4K or 8K TV \/ projector \/ media player and you want a dedicated outlet optimized for video performance.\u003c\/p\u003e\n\u003cp\u003e\u003cimg class=\"emoji\" role=\"img\" draggable=\"false\" src=\"https:\/\/s.w.org\/images\/core\/emoji\/17.0.2\/svg\/2714.svg\" alt=\"✔️\" width=\"15\"\u003e You want to tuck the conditioner out of sight — behind a cabinet, behind the TV, or on a shelf — while still getting legitimate Non-Sacrificial Surge Protection.\u003c\/p\u003e\n\u003cp\u003e\u003cimg class=\"emoji\" role=\"img\" draggable=\"false\" src=\"https:\/\/s.w.org\/images\/core\/emoji\/17.0.2\/svg\/2714.svg\" alt=\"✔️\" width=\"15\"\u003e You want AudioQuest’s Connected Equipment Protection Warranty in addition to standard product coverage.\u003c\/p\u003e\n\u003c!-- FEATURES \u0026 SPECIFICATIONS TABLE --\u003e\n\u003ch2\u003eFeatures \u0026amp;

AudioQuest states the PQ-2 reduces AC noise with differential-mode filtering and protects your gear with Non-Sacrificial Surge Protection.\u003c\/p\u003e\n\u003cp\u003eThe dedicated 4K\/8K Video-Optimized outlet adds extra noise-dissipation tuned for high-resolution video. Many users report a real bump in picture contrast and black-level detail after plugging a TV or projector into it.\u003c\/p\u003e\n\u003ch3\u003eWhich outlet do I use for what?\u003c\/h3\u003e\n\u003cp\u003ePlug your TV, projector, or 4K\/8K media player into the dedicated 4K\/8K Video-Optimized outlet. Plug a soundbar, AV receiver, subwoofer, or other higher-draw component into the High-Current outlet.\u003c\/p\u003e\n\u003cp\u003ePlug source gear — streamers, DACs, CD players, preamps, cable boxes, game consoles, networking gear — into any of the four Linear-Filtered outlets. Use the USB ports for phones, tablets, and remotes.\u003c\/p\u003e\n\u003ch3\u003eDo I need this if I already have a good surge protector?\u003c\/h3\u003e\n\u003cp\u003eSurge protection and power filtering are two different jobs. A basic surge strip blocks voltage spikes but does nothing for AC noise — and most use throwaway MOV parts that wear out with every surge.\u003c\/p\u003e\n\u003cp\u003eThe PQ-2 handles both: Non-Sacrificial Surge Protection that withstands repeated 6,000V \/ 3,000A surges, plus differential-mode linear noise filtering across 30 kHz – 1 GHz.\u003c\/p\u003e\n\u003ch3\u003eHow does the PQ-2 compare to the PQ-3?\u003c\/h3\u003e\n\u003cp\u003eThe PQ-2 has 6 outlets (including 1 dedicated 4K\/8K video-optimized outlet and 1 High-Current outlet), differential-mode filtering, and 2 USB ports.\u003c\/p\u003e\n\u003cp\u003eThe PQ-3 has 8 outlets (2 High-Current), adds common-mode filtering on top of differential, and includes 4 USB-A ports with 4.8A total charging.\u003c\/p\u003e\n\u003cp\u003ePick the PQ-2 if you want the dedicated 4K\/8K video-optimized outlet or need the smallest footprint. Step up to the PQ-3 if you need more outlets, the second filter, or more USB charging.\u003c\/p\u003e\n\u003ch3\u003eWhere can I install this?\u003c\/h3\u003e\n\u003cp\u003eThe PQ-2 is built to hide. With the floor-mounting stand attached, it stands vertically and slides into tight spaces behind cabinets or entertainment units. Remove the stand and the PQ-2 lies flat on a shelf — either way, all six outlets remain accessible.\u003c\/p\u003e\n\u003cp\u003eThe 7-foot AudioQuest power cord gives you flexibility in where you mount it relative to the nearest wall outlet.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c!-- WHAT'S IN THE BOX --\u003e\n\u003ch2\u003eWhat’s in the Box\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAudioQuest PowerQuest 2 Power Line Filter\u003c\/li\u003e\n\u003cli\u003eDetachable floor-mounting stand\u003c\/li\u003e\n\u003cli\u003e7’ AudioQuest Directionally Optimized Concentric-Geometry Power Cord\u003c\/li\u003e\n\u003cli\u003eOwner’s manual and warranty documentation\u003c\/li\u003e\n\u003cli\u003eAudioQuest Connected Equipment Protection Warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c!-- WHY AUDIO ADVISOR --\u003e\n\u003ch2\u003eWhy Audio Advisor?\u003c\/h2\u003e\n\u003cdiv class=\"ec-titlebox-text\"\u003e\n\u003cp\u003e\u003cimg class=\"emoji\" role=\"img\" draggable=\"false\" src=\"https:\/\/s.w.org\/images\/core\/emoji\/17.0.2\/svg\/1f3b5.svg\" alt=\"music note emoji\" width=\"20\"\u003e  \u003cstrong\u003e40+ Years of Expertise\u003c\/strong\u003e — Audio Advisor has served over one million audiophiles since 1981.\u003c\/p\u003e\n\u003cp\u003e\u003cimg class=\"emoji\" role=\"img\" draggable=\"false\" src=\"https:\/\/s.w.org\/images\/core\/emoji\/17.0.2\/svg\/1f504.svg\" alt=\"repeat emoji\" width=\"20\"\u003e  \u003cstrong\u003e60-Day Money-Back Guarantee\u003c\/strong\u003e — Try it in your system.
