Audiolab DC Block Audio Grade Mains Filter & Direct Current Blocker (Black)

Reduce the noise over AC power with the black Audiolab DC Block Single-Outlet Inline Power Conditioner. It is designed to reduce the noise carried over your AC power and, when used with an amplifier, is rated for amps that output up to 300W total. DC Over AC One common issue with AC power is "DC over AC," a problem well known to affect the performance of audio equipment, especially amplifiers. In theory, the AC 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" – myriad household devices that use the AC energy available in the power cycle unevenly, from dimmer switches to kitchen appliances to computer power supplies – causes the waveform to become offset, resulting in the presence of DC voltage on the AC supply.

High-Performance Filtering
The DC Block also contains a high-performance audio filtering circuit that removes RFI/EMI contaminants from the power supply. This is effective in reducing both differential-mode noise (exacerbated by inexpensive switch-mode power supplies used by many home appliances) and common-mode noise (aggravated by airborne interference from phones, Wi-Fi networks, and Bluetooth).

Combining DC Blocking and Filtering
This combination of technologies ensures that the DC Block does more than solve the problem of transformer saturation caused by DC over your AC line; it also helps to unlock the sonic potential of any audio component to which it is connected. The noise floor drops and the sound gains greater focus, with reduced grain, improved clarity, better-defined bass, and "airier" treble.
