The typical mains supply is subject to various kinds of
interference and non-linear loads, which distorts the AC waveform. Asymmetrical
loads will cause the waveform to be offset and result in what is known as ‘DC
on the mains’.
The amount of DC is only small, typically less than 500mV,
but it only takes a small amount of DC to saturate a modern high flux toroidal
transformer. Saturation of the transformer will invariably result in reduced
efficiency and mechanical vibration. This typically manifests in ‘noisy
operation’ and acoustically compromised performance.
Removing the DC from your mains supply will not only restore
efficiency and reduce mechanical hum of noisy transformers, it will also
improve the performance of the connected audio equipment, resulting in greater
clarity and dynamics.
The audiolab DC BLOCK utilizes a simple connection and
intelligent design that will help remove DC from your mains power supply,
As well as DC removal, the audiolab DC BLOCK provides
additional mains conditioning and RF filtering, of both common and differential
mode noise, which further contributes to the optimal operation of your audio
The audiolab DC BLOCK mains conditioner is compatible with
most audio equipment that utilizes an IEC mains inlet and will offer a
no-nonsense, instant improvement to the mains power supply, and ultimately, the
performance of your Hi-Fi system.
