Overview
The Audiolab DC Block 6 is a six-way mains power optimizer designed and engineered in the UK by Audiolab, the British hi-fi electronics maker founded in 1983. It is not a source and makes no sound on its own. Instead, it sits between your wall outlet and your components, cleaning up the AC waveform before it ever reaches your amplifier, streamer, DAC or transport.
Its job is twofold. First, it blocks DC offset that rides on the mains supply, the common cause of mechanical transformer hum and premature transformer saturation. Second, it applies audio-grade high-frequency RFI and EMI filtering to correct the AC waveform and lower the overall system noise floor. Overload protection is built in, and six IEC C13 to C14 cables plus a mains power cord are included so you can connect a full stack straight out of the box.
The DC Block 6 is for anyone running a multi-box Audiolab system, or any listener bothered by transformer buzz and grunge on a busy mains supply. By giving connected electronics a cleaner, quieter feed, it lets each component perform to its potential without adding any sonic character of its own.

Cleaner Power For These Components
The DC Block 6 makes no sound on its own, so pair it with the Audiolab electronics whose power supplies it cleans. Removing DC offset quiets transformer hum, while RFI and EMI filtering lowers the noise floor so these components sound their best.
- Audiolab 9000A A large integrated amplifier draws heavily on its transformer, so blocking DC offset reduces mechanical hum and lets its Class AB output stage run against a quieter background.
- Audiolab 9000P Power amplifiers benefit most from a clean supply; cleaner AC lowers transformer saturation and hum, allowing low-level detail to emerge from a lower noise floor.
- Audiolab 9000N Digital sources are sensitive to mains-borne RFI and EMI; filtering that noise ahead of the streamer helps keep its Roon Ready playback clean and quiet.
- Audiolab 9000Q A preamplifier handles delicate low-level signals, so a lower system noise floor directly supports its transparency and its dedicated MM phono stage.
- Audiolab D9 DAC The D9's ES9038PRO DAC and headphone stage reveal fine detail, so filtering high-frequency mains noise supports the quietest possible background.
Frequently Asked Questions
What does the Audiolab DC Block 6 do?
It is a six-way mains power optimizer that blocks DC offset on the incoming AC and applies high-frequency RFI and EMI filtering to correct the AC waveform, reduce transformer saturation and mechanical hum, and lower your system noise floor.
Is the DC Block 6 a source or does it make sound?
No. It makes no sound on its own. It sits between the wall and your components to give them a cleaner power supply.
How many components can I connect?
It has six IEC C13 to C14 outputs, so you can power a full multi-box stack from a single unit.
Does it come with cables?
Yes. It includes six IEC C13 to C14 cables plus a mains power cord.
Will it stop my amplifier from humming?
Transformer hum is often caused by DC offset on the mains. The DC Block 6 blocks that DC offset, which helps reduce mechanical transformer hum and saturation.
What is DC offset and why does it matter?
DC offset is a small direct-current component that can ride on your AC supply. It can push transformers toward saturation and cause audible mechanical buzz. Blocking it helps transformers run quietly and cleanly.
What does the RFI and EMI filtering achieve?
It filters high-frequency radio and electromagnetic interference riding on the mains, helping correct the AC waveform and lower the overall system noise floor.
Does the DC Block 6 have overload protection?
Yes, overload protection is built in.
What finishes are available?
It is available in Black or Silver.
What are the dimensions and weight?
It measures 3.1 x 17.5 x 12.1 inches and weighs 10.1 pounds.
Which components should I connect to it?
Connect your active electronics such as integrated amplifiers, power amplifiers, preamplifiers, streamers, DACs and CD transports. It improves the power feeding any component you plug into it.
Will it change the tonal character of my system?
It adds no sound of its own. Its purpose is to deliver cleaner power so your existing components can perform to their potential against a lower noise floor.
Can I use it with non-Audiolab equipment?
Yes. Any component with a standard IEC input can benefit from the cleaner supply, though it pairs naturally within an Audiolab system.
Does it regenerate power or just filter it?
It is a mains power optimizer that blocks DC and filters RFI and EMI to correct the AC waveform. It is not described as a regenerator.
Is it suitable for a full Audiolab stack?
Yes. With six outputs and included cables, it is well suited to powering a complete Audiolab system such as an integrated amplifier, streamer and CD transport.
Does it help digital sources as well as amplifiers?
Yes. Digital sources like streamers and DACs are sensitive to mains-borne noise, so filtering RFI and EMI ahead of them supports cleaner, quieter playback.
Who designs and builds Audiolab products?
Audiolab is a British hi-fi electronics maker founded in 1983, with products designed and engineered in the UK.
What warranty does the DC Block 6 carry?
It is covered by a 3 year parts and labor warranty through Audiolab via MoFi Distribution for the original owner.
Do I still need good power cords with it?
The unit includes six IEC C13 to C14 cables and a mains power cord, so you have everything needed to connect your system out of the box.
