DC blocking in the AC mains power, EMI suppression and over voltage protection in one circuit.
A problem well known to affect the performance of audio equipment is DC on the mains, especially power amplifiers with large toroidal transformers are sensitive to these DC levels. In theory the mains electricity we obtain from the sockets in our homes should be pure AC with a perfectly symmetrical sine wave alternating between positive and negative phases. However, the presence of asymmetrical loads like household devices that use the AC energy available in the mains cycle unevenly, from dimmer switches to kitchen appliances and computer power supplies causes the waveform to become offset, resulting in the presence of DC voltage on the AC supply. This DC voltage often result in humming power transformers.
The Audio products MPOA largely reduces the DC part in the AC line and in addition suppresses EMI with a powerful mains filter circuit and also adds a over voltage protection circuit to the mix.
