Product Details
- Got Big Amplifier? Bye Bye Mechanical Hum.Many 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.FeaturesSmall design won’t block connectors sockets or cablesIntelligently stops any DC voltage from the mains to eliminate transformer humEMI shielding is retained while equipment safety is unaffectedWhat's in the BoxDC Blocker+ DC Noise Blocker
