It therefore eliminates amplifier transformer hum.\u003c\/p\u003e\n \u003ch3\u003e\u003cstrong\u003eSpecs\u003c\/strong\u003e\u003c\/h3\u003e\n \u003cul\u003e\n \u003cli\u003eZERO DC Block technology: Blocks incoming DC up to 1,200mV\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eVoltage rating: 90–240 volts\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eMaximum current rating: 7A\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eMax amplifier power: 880W\/VA on 220V, 440W\/VA on 110V\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eContinuous current rating: 4A\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eUniversal IEC: Hospital-grade IEC connectors\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eDimensions: 68 x 37 x 32 mm \/ 2.7” x 1.5” x 1.3”\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eWeight: 63g \/ 2.2oz\u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003eNote: The image colour may differ from the actual product due to lighting; refer to the product for accuracy.\u003c\/li\u003e\n \u003c\/ul\u003e","brand":"iFi","offers":[{"title":"Default Title","offer_id":46866191777967,"sku":"APS-1163-1","price":129.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/6415\/2239\/files\/apos-audio-ifi-accessory-ifi-audio-silentpower-dc-blocker-blocks-any-dc-offset-iec-connector-1208375885.webp?v=1777716199","url":"https:\/\/freshized.com\/products\/ifi-audio-silentpower-dc-blocker-blocks-any-dc-offset-iec-connector","provider":"Freshized","version":"1.0","type":"link"}
