Audiolab DC Block 6 Main filter

The DC BLOCK 6 has one single mains input and offers six IEC outlets for the mains power supply of your audio system components. What block 6 does is remove DC from the AC mains supply, transformer hum, and RF interference, meaning your Hifi will sound better than ever. It also isn't limited to only Audiolab equipment, you can use it with a great number of other audio brands including home cinema amps.

The DC Block 6 has been designed to improve the quality of AC electricity that feeds our audio and AV systems.

Mains electricity has a fundamental influence on the audio signal as it passes through a system, from source to amplifiers to speakers. The mains supply in a typical home is subject to interference induced by a range of issues, causing the AC waveform to distort before it reaches each component. This creates noise in the audio signal, which degrades sound quality – a situation that continues to worsen with more and more electrical devices being added to the home mains supply.

Perfectly sized to match Audiolab components and to easily fit into a typical hi-fi shelf/rack system, the DC BLOCK 6 also features a front-panel voltmeter display (which can also be powered off for a more discreet placement).

By blocking, or cancelling, the DC voltage found within the AC mains supply, the DC BLOCK 6 corrects the DC offset and rebalances the mains sine wave. But tackling ‘DC on the mains’ is not the only benefit delivered by this dual-action device – it also contains a high-performance audio-class filtering circuit that removes RFI/EMI contaminants from the mains supply. This is effective in reducing both differential-mode noise (exacerbated by cheap switch-mode power supplies used by many home appliances) and common-mode noise (aggravated by airborne interference from phones, Wi-Fi networks and Bluetooth).

Who is Audiolab?

Originally created by Philip Swift and Derek Scotland over 30 years ago, Audiolab has always designed high-performance electronics at real-world prices and with a great build quality. The original 8000 series have been re-engineered for the 21st century and the resulting 6000 models extended to embrace digital music streaming.
