This hum is caused by a small amount of DC voltage in the mains cable, which can saturate the main transformer and cause it to hum. The DC Blocker is placed at the IEC (power input on the back) of the amplifier and blocks DC voltage from entering the amplifier, preventing the hum.<\/p>\n<p>Key specifications and features of the Ifi Audio DC Blocker include:<\/p>\n<p>- Works on a voltage range of 90-240V<br \/>\n- Has a maximum rating of more than 7A, with a continuous current rating of 4A.<br \/>\n- Compact size that does not obstruct other plugs, sockets or cables<br \/>\n- Retains EMI shielding<br \/>\n- Does not affect equipment safety<br \/>\n- Uses high performance glass passivated semiconductor with a high case dielectric strength of 1500VRMS. It also uses a flameproof IEC socket\/plug\/chassis made of flameproof polymers (UL94-V0).<\/p>\n<p>By removing DC from the equation, the DC Blocker allows the transformer to operate in an optimal environment, effectively eliminating mechanical transformer hum.<\/p>","protected":false},"excerpt":{"rendered":"<p><h3>A product for those who have problems with hum from amplifiers.<\/h3><br \/>\nDC-Blocker removes the hum from amplifiers. If you plug your ear, or if it is really bad, you can hear a humming sound from the listening position. This is because a small DC voltage finds its way to the transformer which becomes \"saturated\" and starts humming.<br \/>\nIFi Audio has developed a nifty little device that plugs into the power socket of your device. On the back of the CD-Blocker you insert your power cable.
