The Audiolab DC Block Direct Current Blocker removes transformer hum from your components caused by DC, creating greater clarity and dynamics in the music.

The Audiolab DC Block eliminates transformer hum, caused by a small amount Direct Current leaking into the transformer from the mains. This DC can easily saturate a modern toroidal transformer, resulting in reduced efficiency and mechanical vibrations. The DC Block removes the direct current from the mains supply of your component, reducing the hum and improving performance, with greater clarity and detail.

The DC Block uses intelligent design, along with a simple connection to remove the DC from your mains power supply. The DC Block also provides additional mains conditioning and Radio Frequency filtering, to remove extra noise from the power supply for an optimal operation of your equipment. With a simple IEC connection, the DC Block is easy to position within your system, to remove transformer hum.
