Holton DC Blocker One


This device might be useful and helpful for some of you. Holton writes: "If your amplifier has ever suffered from a noisey buzzing power transformer that seems to come and go depending on the time of day. Your sound system is most likely suffering from DC on the AC mains. DC on the mains is generated from a lot of modern appliances like air conditioners, laser printers, switchmode power supplies etc. its causes clipping of the AC mains waveform and this generates direct current to be formed which is piggy backed on the AC mains."

"The result is it saturates power transformers primary winding creating a very loud acoustic buzz which can more often than not be heard across your listening room.

It also robs the power transformer of power and dynamics, which in turn rob the amplifier of sound quality.

The Holton DC blocker is a very high power AC mains conditioner which not only removes the DC from the mains but also filters high frequency noise from the mains as well.


The Holton DC blocker is capable of power devices as high as 2400 watts from your standard Australian GPO without any drop off in power delivery.

The DC blocker also comes with high quality AC volt and AC current meters so you can see exactly what is happening with what you are powering.

The result of using the Holton DC Blocker is restored dynamics and resolution in your sound system and no noisey power transformers.


The Holton DC Blocker One is designed to power your entire sound system not just your power amplifier. The best place to wire in the Holton DC Blocker One is between your household AC Mains GPO and your multi outlet power board.

The Holton DC Blocker One can be supplied with UK BS1363 13 Amp 230VAC Mains Outlet or USA 2143 15 Amp 125VAC AC Mains Outlet upon request."
