Audiolab DC Block 6 Power Conditioner 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. Manufacturers Details: 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. Engineered With Care: 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 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). Key Features: 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). Suitable for all audio or AV systems Removes DC from AC mains supply, transformer hum, and RF interference Offers radical improvement in mains quality, transformer and power supply performance, and therefore sound quality Six independent outlets for source components; power amps, preamps, integrated amplifiers, CD players, DACs, etc. One single mains input connection Simplified OLED display on voltmeter with display on/off option Ships with complementary 6x IEC C14 to C13 jumper chords to go from your product to the conditioner Gabi recommends: The perfect companion to the Audiolab DC Block 6 Power Conditioner is a good quality power cable to your wall-socket - like the IsoTek Initium. This will provide extra protection to minimise the amount of Differential Mode Noise entering your power signal chain. * Note: The audiolab DC BLOCK is designed for audio equipment with variable power requirements up to max. Peak Load and should not feed any permanent high power loads such as heaters or similar.
