A more cost effective solution to the problem of DC on the mains (DC is responsible for amplifier hum and low level humming through your speakers amongst other things). The MCRU DC blocker has been proven to reduce or eliminate the humming/buzzing from your amplifiers transformer as well as blocking DC, in addition we have further ehanced this new design to include some non intrusive filtering in the main unit.

The DC blocker has a short length of mains cable terminated with either a standard C13 kettle lead type IEC connector or a 16 amp high current C19 IEC connector. The other side has an IEC inlet to allow you to attach your own power lead.

We recommend this model DC blocker to power low current individual units such as CD players, DAC's, tuners etc etc and low current draw amplifiers.

If you wish to use the DC blocker on power amplifiers, monoblocks, mains conditioners and regenerators we recommend our Ultimate DC blocker here. 

Both the standard and ultimate in line versions are also available as a complete mains lead available on request.
