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.

Delivers as promised
In my system I would simply describe the sound as cleaner and better focused with the DC blocker. Better sound stage depth, better instrument separation and even a very slight improvement in the timbre of instruments probably due to the reduction in what I would describe as glare in the upper mid.

Noticeable improvement for me
I had been in the cable tweaking deniers category until I started doing so. I noticed that my 15 year old Audiolab 8000S amp transformer was humming. I don't know if this is new or if I just hadn't noticed it before since it isn't noticeable unless you know to listen for it. If mains hum is because of DC in the AC mains then eliminating that DC can stop the hum.
Whilst this mains filter / conditioner hasn't stopped the hum, probably just the age of the amplifier, I'm glad I've added the device to my system. Lower frequencies are more powerful without being louder and the whole system is clearer and more sprightly.
I've just ordered another one, this time for my CD player.

Who would have believed it!
I must admit purchased on a whim whilst looking for a Tacima mains conditioner.
Well gob smacked, inserted between mains and amplifier music still the same but so much cleaner and vibrant.
Very happy man.
