{"product_id":"audio-hungary-qualiton-filter","title":"Audio Hungary Qualiton Filter","description":"\u003cp\u003eThe Qualiton Filter is a vacuum tube power line filter for a complete audio system. It connects between the wall outlet and the components, and it is designed to remove power line noise before it reaches them. Qualiton designs and builds its components in Nyíregyháza, in eastern Hungary.\u003c\/p\u003e\n\u003ch3\u003eTube-based EMI cancellation\u003c\/h3\u003e\n\u003cp\u003eAt the center of the Filter is an active circuit that cancels electromagnetic interference (EMI) on the power line. The circuit runs on four 6H30Pi double triodes, which stand in a row at the front of the chassis. The same unit also provides broadband filtering, DC blocking and transient surge protection.\u003c\/p\u003e\n\u003cp\u003eEMI suppression is bidirectional. The Filter works on noise arriving from the mains and on noise that connected components send back onto the line. Its power components are from Furutech.\u003c\/p\u003e\n\u003ch3\u003eFour output channels\u003c\/h3\u003e\n\u003cp\u003ePower comes in through a single IEC inlet with a built-in fuse holder. On the rear panel it is divided into four output channels. The front panel carries the main switch and a power indicator.\u003c\/p\u003e\n\u003cp\u003eThe connection diagram in the manual shows one Filter supplying a full system: stereo amplifiers, a preamplifier or phono stage, a turntable, a CD player, a tape deck and a media server.\u003c\/p\u003e\n\u003ch3\u003eSetup\u003c\/h3\u003e\n\u003cp\u003eThe tubes fit under a removable protective cover, and Qualiton recommends using only the tubes supplied with the unit. Because of the tubes, the Filter warms up in use, and the manual asks for at least 200 mm of open space around it for ventilation. Each unit is configured at the factory for 115 V or 230 V mains and connects to a grounded outlet.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eType: vacuum tube power line filter\u003c\/li\u003e\n\u003cli\u003eVacuum tubes: 4 x 6H30Pi double triode\u003c\/li\u003e\n\u003cli\u003eInput: 1 IEC AC inlet with built-in fuse holder\u003c\/li\u003e\n\u003cli\u003eOperating voltage: 115 V \/ 60 Hz or 230 V \/ 50 Hz (factory configured)\u003c\/li\u003e\n\u003cli\u003eMaximum operating current: 10 A\u003c\/li\u003e\n\u003cli\u003eOutput channels: 4\u003c\/li\u003e\n\u003cli\u003eMaximum output current per channel: 8 A\u003c\/li\u003e\n\u003cli\u003ePower requirement: 80 W idle\u003c\/li\u003e\n\u003cli\u003eWeight: 10 kg (22 lb)\u003c\/li\u003e\n\u003cli\u003eDimensions: 40 x 33 x 16 cm (15.7 x 13 x 6.3 in)\u003c\/li\u003e\n\u003cli\u003eIncluded: Filter, 4 x 6H30Pi tubes, standard mains cable, pair of gloves, user's manual\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Audio Hungary","offers":[{"title":"Default Title","offer_id":50908095217883,"sku":null,"price":8000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1363\/6553\/files\/audio-hungary-qualiton-filter-front.jpg?v=1792727058","url":"https:\/\/almaaudio.com\/products\/audio-hungary-qualiton-filter","provider":"Alma Music and Audio","version":"1.0","type":"link"}
