The primary socket is connected to a switchable supply of electrical power.

The equalizer may determine locations of a principal tap, a platform noise tap, and a pre-cursor tap in a feedforward path of an equalizer.

The receiver may align the portable tap in the feedback path with the principal tap in the feedforward path.

A power socket includes an input power supply (10), a main socket circuit (21) and an auxiliary socket circuit (31).

The update coefficient for each tap is computed independently based on the power of each tap (402) relative to the main tap power.

The main socket circuit (21) and the auxiliary socket circuit (31) are both electrically connected with the input power supply (10).

For complete electrical disconnection, pull out the main plug.

For a complete electrical disconnection, pull out the main plug.
