Description

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.

Key Features

  • DC Voltage Elimination: The DC Blocker intelligently prevents any DC voltage from entering your amplifier, particularly beneficial for larger amplifiers with susceptible toroidal transformers.
  • Universal Application: With a voltage range of 90-240V and a maximum rating exceeding 10A, the DC Blocker is versatile and suitable for various applications.
  • Safety First: Rest assured, the DC Blocker prioritizes equipment safety. Its design ensures that EMI shielding is retained, and it won't interfere with other connectors, sockets, or cables.
  • Zero DC Block Technology: Our DC Blocker is equipped with advanced Zero DC Block technology, effectively stopping DC from entering your amplifier and eradicating transformer hum.
  • High-Performance Components: Featuring high-performance glass passivated semiconductors with a high-case dielectric strength of 1500VRMS, the DC Blocker is UL listed and incorporates flame-resistant materials for added safety.
  • Compact Design: The small size of the DC Blocker, along with its flame-resistant IEC socket/connecter/chassis, ensures a universal fit without obstructing other connections.
