The DC BLOCK is a very compact and attractive product which, as its name suggests, has been specifically designed to block the DC input from the mains in all kinds of audio electronics. The idea behind this versatile accessory is the established fact that, as a general rule, the AC signal present in the mains is subject to various types of interference and distorting non-linear loads. In particular, asymmetrical loads will cause shunts in the AC signal, resulting in what is known as "DC current in the AC electrical signal". The magnitude of this DC current is small, in the order of 500 mV, but a small amount of DC current is enough to saturate a modern high-flux toroidal transformer, resulting in reduced efficiency and increased mechanical vibration. This is where the DC BLOCK comes in, combining a simple connection with an intelligent design to instantly eliminate the DC current present in the mains signal, to which it adds additional conditioning of the latter and filtering of the RF signals, both processes that contribute to optimising the performance of any audio component.
