Audiolab DC Block 6 Mains Filter and Direct Current Blocker (Silver)

Description

DC Block 6

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.

DC mains supply

One common issue is ‘DC on the mains’ – a problem that is
well known to affect the performance of audio equipment, especially amplifiers.
In theory, the mains electricity we obtain from the sockets in our homes should
be pure AC, with a perfectly symmetrical sine wave alternating between positive
and negative phases.

DC Voltage

The AC transformers commonly used in home audio equipment
cannot tolerate the presence of significant levels of DC voltage without being
compromised. Less than 500mV of DC – typical in an average household
electricity supply – can be sufficient to cause toroidal transformers of the
kind often found in amplifiers to become saturated, which adversely affects
sonic performance and may cause audible mechanical vibration.

The audiolab DC BLOCK 6 is a six-way solution for this
all-too-common problem.

By blocking, or cancelling, 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).

A specialized six-way power optimization device of such
impressive efficacy, DC block 6 is available in black or silver. It comes with
a full set of power cables – six IEC C14 to C13 cables to connect its outlets
to the user’s system components, plus a cable to plug it into the mains.

Simple setup

The DC BLOCK 6 has one single mains input and offers six IEC
outlets for the mains power supply of your audio system components.

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).
