The Audiolab 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.
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 affcts 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 Audiolab DC Block corrects the DC offset and rebalances the mains sine wave (see illustration above). 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).
