Filtering the supply lowers noise and distortion on the mains line before they reach the connected equipment. The version offered here is the European one, with Schuko sockets and plug.\u003c\/p\u003e\n\u003ch3\u003eOutlets and filtering\u003c\/h3\u003e\n\u003cp\u003eThe outlets are split into two groups. The high-current ones are meant for power amplifiers, AV receivers, soundbars and subwoofers. The linear-filtered ones feed audio and video sources, computers, modems and routers. Linear noise dissipation keeps the reduction of disturbances constant, which favours a quieter background and a sound rich in detail.\u003c\/p\u003e\n\u003ch3\u003eSurge protection\u003c\/h3\u003e\n\u003cp\u003eProtection is non-sacrificial: it copes with repeated surges without its parts wearing out over the years, and so without losing effectiveness after each event. If mains voltage rises beyond the safe level, the extreme-voltage shutdown opens the main circuit relay in under 0.25 seconds; reset is automatic once the supply is back at safe values.\u003c\/p\u003e\n\u003ch3\u003eDetachable cable and mounting\u003c\/h3\u003e\n\u003cp\u003eThe 2-metre PQ-415 detachable power cable is supplied. Its conductors are Semi-Solid Long-Grain Copper: the strands are compacted and hold the same place in the bundle, which lowers the distortion caused by interaction between wires, while long-grain copper limits the distortion produced by the grain boundaries of the metal. Direction-Controlled conductors lead induced noise away from the most sensitive circuits in the system. The flat wall plug helps in installations where space is tight, and the supplied 2U rack ears allow fitting into a rack cabinet.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eOutlets in two groups: high current for amplification, linear filter for sources\u003c\/li\u003e\n\u003cli\u003eLinear noise dissipation\u003c\/li\u003e\n\u003cli\u003eNon-sacrificial surge protection\u003c\/li\u003e\n\u003cli\u003eExtreme-voltage shutdown in under 0.25 seconds, with automatic reset\u003c\/li\u003e\n\u003cli\u003e2-metre PQ-415 detachable power cable with flat wall plug\u003c\/li\u003e\n\u003cli\u003e2U rack-mounting ears supplied\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AudioQuest","offers":[{"title":"Default Title","offer_id":56981343994200,"sku":"AQ-POWERQUEST-303","price":599.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0615\/5278\/7645\/files\/AudioQuest_PowerQuest_303_1.jpg?v=1774517257","url":"https:\/\/videosell.it\/en\/products\/audioquest-powerquest-303","provider":"Videosell store","version":"1.0","type":"link"}
