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.

iFi DC Blocker
It's no secret that many large amplifiers suffer from an irritating mechanical hum, often emitted from the toroidal transformer itself. This bothersome noise becomes noticeable when you place your ear close to or next to the chassis.
The culprit? A small amount of DC voltage in the mains, finding its way to the mains transformer, causing it to become 'saturated' and hum persistently.
Enter the iFi Audio DC Blocker – a smart solution placed at the IEC (rear power inlet), effectively preventing DC from infiltrating the amplifier. This simple yet ingenious device eliminates transformer hum, providing a quieter listening experience.
Smart and effective.
Enjoy all the benefits of eliminating annoying hum with no drawbacks. The DC Blocker intelligently prevents any DC voltage from the mains, ensuring amplifier safety and retaining EMI shielding.
Behind every exceptional component lies a DC Blocker.
The larger the amplifier, the more susceptible the toroidal transformer is to residual DC voltage. Simply add the DC Blocker at the IEC to halt DC intrusion.
Specifications:
Voltage range: 90-240V
Maximum rating: >7A, continuous current rating: 4A
Compact size, universal application, does not obstruct other connectors, sockets, or cables
Featuring ZERO DC Block technology, this device halts DC from entering your amplifier, effectively eradicating transformer hum. With a high-performance glass passivated semiconductor and UL-listed flame-resistant components, it ensures safety and reliability while retaining EMI shielding.
By removing unwanted DC and eliminating mechanical transformer hum, the DC Blocker creates an optimal operating environment for your amplifier. Experience pristine audio with zero DC pass-through, courtesy of the iFi Audio DC Blocker.
