Bye Bye Mechanical Hum.\u003c\/h2\u003e\n\u003cp\u003eMany large amplifiers have a really annoying mechanical hum (emitted from the toroidal transformer itself). You can hear it when you place your ear close or next to the chassis. This is caused by a small amount of DC voltage in the mains which makes its way through to the mains transformer, it will become ‘saturated’ and start to hum like a trooper. The DC Blocker is a clever device that you place at the IEC (at the rear power inlet) and as its name implies, it stops DC from getting into the amplifier. It therefore eliminates amplifier transformer hum.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSmall design won’t block connectors sockets or cables\u003c\/li\u003e\n\u003cli\u003eIntelligently stops any DC voltage from the mains to eliminate transformer hum\u003c\/li\u003e\n\u003cli\u003eEMI shielding is retained while equipment safety is unaffected\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"iFi Audio","offers":[{"title":"Default Title","offer_id":50830697791705,"sku":"181230","price":149.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1123\/6098\/files\/0_c45971b1-75da-48f5-8614-ad3a26555db0.jpg?v=1793048075","url":"https:\/\/skybygramophone.com\/products\/ifi-audio-dc-blocker-dc-noise-blocker","provider":"GRAMOPHONE","version":"1.0","type":"link"}
