Delivering ‘clean’ power to your amp, the Audiolab DC Blocker reduces transformer noise, letting you hear more of the music and less of the electronics.

Direct Current Blocker – banish the hum
DC (Direct Current) signals within the mains current may be small but can noticeably affect sound quality. As the DC current enters a toroidal power transfer it becomes saturated, reducing the transformer’s efficiency and causing audible vibration. Connecting the DC Blocker reduces the mechanical hum and restores the mechanical efficiency – letting you concentrate on the music and not the background noise.

Mains conditioner and RF filter
As well as DC removal, the DC Block also provides additional mains conditioning and RF filtering. These help reduce background noise further still, as noise from other components on the mains system (such as a fridge or dimmer switch switching on and off) is effectively filtered out.

Improves the entire system
With a quieter mains signal being feed to your amplifier, the whole system benefits. A quieter amp means less distortion relayed to other components, helping reduce distortion and enhance music dynamics.

Easy to connect
No special installation or even additional mains sockets are required to fit the DC Blocker to your system. Simply plug into your amp’s IEC power socket and then connect to the mains socket vacated by the amp’s power cable.

Styled to match your system
With its clean, crisp lines, the DC Block looks every bit as sleek as you’d expect from the Audiolab brand. Available in black or silver, the DC Block perfectly matches Audiolab’s other products and also blends well with components from other brands.

Hear the music you’ve been missing, with the Audiolab DC Blocker.

Rated 5 out of 5 by from Toroidal buzzing vanished My oven was causing my Mackie nearfield monitors (with inbuilt toroidal transformers) to buzz when the heater was energised. A little bit of reading, and the fact that it was happening in both speakers simultaneously led me to believe that DC offset was the cause. The circuitry inside is pretty simple, but I looked at the price of the components to purchase in small quantities and it was going to cost 80% of the purchase price of this unit to build it myself, so this seemed like the most sensible option, even when budget constrained. Pleased to say it has completely eliminated the buzz, and the noise floor seems to have gone down a touch, though hard to say for sure. I've got both monitors powered by the same unit at the moment. In theory, at full whack they'll overload it, but as I never go anywhere near full whack, this should be suitable, but remains to be seen

Rated 5 out of 5 by from Works exactly as described A similar story to other reviewers. I bought this to try and cure a slightly buzzing toroidal transformer. The Audiolab DC Block did that job and more! I was not expecting an overall improvement in sound quality, but it was there from switch on. Great service from Richer Sounds as always. I read about DC Block in Hi-Fi World magazine at lunchtime on Monday, ordered the item from Richers that afternoon, and it was delivered, plugged in and working its magic on Tuesday morning! Can't get much better than that.

Rated 5 out of 5 by from Did what it said on the tin.....and so much more I had some DC hum in my Rega Aethos amp. Research suggested the Audiolab would solve the problem. Plugged it all in and hey presto, no more hum. Marvelous. What I wasn't prepared for was the marked improvement in so many areas of the sound quality. Soundstage is wider and deeper. Vocals are sharper and more defined. Presentation on the whole is just a little cleaner and more enjoyable. It's definitely worth an audition. Top bit of kit.

Rated 5 out of 5 by from Surprisingly Good So having bought a new Audiolab amp and cd transport back in November 2021 and reading the reviews I thought I would try one of these out. Happy to report the reviews are correct. The DC Block works surprisingly well connected to my 6000A. Difficult to put my finger on exactly what is better but the whole sound of the system is just that bit cleaner with a little more crispness in the highs and definition in the lows. Made such a difference that I bought a second one for the CD transport. Very pleased with my purchase and would happily recommend to anyone.

Rated 5 out of 5 by from Simple cheap way to improve your sound I did not have any audible hum from my system. But thought for £99 I would see what difference the DC Block made to my Audiolab 6000a amplifier. A noticeable difference. So much so I have now ordered another one.
