The Audiolab DC Block 6 Direct Current Blocker Black (Open Box) is a little Gem. DC (Direct Current) components in the mains current might be small but can have a quite significant effect on sound quality. For instance, when the DC current is supplied to the magnetic core of a toroidal power transformer, the core becomes saturated.
Thereby severely limiting the output capacity and resulting in the production of an audible hum. This Open Box model is offered at a huge discount. Saving £20.00 off the new price. Grab this bargain now and save
Audiolab DC Block 6 Direct Current Blocker Black (Open Box)
The use of the DC Block can therefore lead to the reduction of the unwanted mechanical hum and the reviving of the mechanical efficiency. So that one can be able to focus solely on the music without the distraction of the background noise.
Mains Conditioner And RF Filter
Besides preventing DC, the DC Block also functions as a mains conditioning device and RF filter. These are major contributors towards reducing background noise by cutting out the noise which results when other appliances connected to the mains (e.g. a refrigerator, dimmer switch, etc.) are being switched on and off.
Very Easy to Install
With just one primary power input. The DC BLOCK 6 unit provides six outlets with IEC connectors for delivering the mains power to your audio system device components.
The DC BLOCK 6 with its dimensions not only suit Audiolab components. But also practically serve as the standard size of a hi-fi type shelf/rack system. Additionally it comes with a voltmeter on a front panel (the display of which can be temporarily turned off for a more discreet placement).
Safeguards Your Equipment
Besides blocking DC noise. This unit acts as a protector for your audio gear against damage resulting from unstable power supply. By minimizing the strain on system components. It indirectly contributes to the longevity of your setup.
Emptied Packaging, Not a Performance
Getting one that has been opened doesn’t necessarily mean getting less power. Even if the DC Block 6 is opened and used it still provides dependable results. You enjoy the same top-notch sound experience at a lower price.

Summary of the Audiolab DC Block 6 Direct Current Blocker Black (Open Box)
The DC Block 6 is the answer to power noise-related issues. Cleaner power results in better sound from your hi-fi components. You will notice a change in sound that makes a difference, especially if you are an audiophile.
Protects Your Investment
By blocking, or cancelling, DC voltage residing in the AC mains supply, DC Block 6 eliminates the DC offset and restores balance to the mains sine wave. However addressing the issue of ‘DC on the mains’ is not the only advantage provided by this dual-action device. It also features a high-performance, audio-class filtering circuit that cleans the mains supply by removing RFI/EMI pollutants.
Reducing Common Mode Noise
It works well in reducing differential-mode noise (which can be made worse by cheap switch-mode power supplies that are used by many home appliances) as well as reducing common-mode noise (which can be worsened by airborne signals such as from phones, Wi-Fi networks, and Bluetooth).
