You can hear it when you bring your ear close to or next to the chassis.\u003c\/p\u003e\n\u003cp\u003eThe DC Blocker+ is a smart device that, when you place it at the IEC (the rear power inlet), prevents DC from getting into the amplifier, thus eliminating transformer hum.\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"iFi DC Blocker+ Power Filter Lifestyle 1\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0065\/4432\/6771\/files\/iFi_DClocker-slate-26.png?v=1722444568\"\u003e\u003c\/p\u003e\n\u003ch2\u003ePlus.
