DC offset present on household mains can cause the toroidal transformers commonly used in amplifiers and other Hi-Fi equipment to become partially saturated, potentially increasing mechanical vibration and compromising power-supply performance. The DC Block 6 corrects this imbalance by blocking up to 1.2 volts of DC offset from the incoming mains supply. Audiolab complements its DC-blocking circuitry with high-frequency mains filtering designed to reduce RFI and EMI contamination from appliances, switching power supplies, wireless networks, mobile devices and other sources of electrical interference. Six individually connected IEC outputs allow multiple system components to benefit from the same power-conditioning platform, making the DC Block 6 a practical centralized solution for complete two-channel and home entertainment systems. Highlights & Benefits Blocks Up to 1.2V of DC Offset — Corrects DC contamination on the mains supply that can cause transformer saturation and unwanted mechanical vibration. Six-Way Power Distribution — Six IEC outputs provide conditioned power for multiple source components, amplifiers and other compatible audio or AV equipment. High-Frequency RFI/EMI Filtering — Helps reduce both differential-mode and common-mode electrical noise before it reaches connected components. Up to 10A Total System Load — Each IEC connection supports up to 8 amps individually, with a combined maximum load of 10 amps across the unit. Complete Cable Package Included — Six IEC C13-to-C14 component cables and a mains power cord are supplied for straightforward system installation. Technology & Design DC Offset Blocking Circuit — The DC Block 6 removes DC voltage riding on the AC mains waveform, helping rebalance the positive and negative portions of the sine wave before power reaches connected components. Audio-Class High-Frequency Filtering — Integrated filtering targets unwanted electrical contamination carried through the mains supply, including interference generated by switching power supplies and household electronics. Common-Mode & Differential-Mode Noise Reduction — The filtering architecture addresses both noise carried between power conductors and interference coupled into the mains from wireless and airborne sources. Six Independent IEC Connections with Protection — The rear panel provides six IEC power outputs along with overload protection, allowing several system components to share the DC-blocking and filtering circuitry. FAQ — Audiolab DC Block 6 What does the Audiolab DC Block 6 do? The DC Block 6 blocks DC offset on the household AC mains supply and filters high-frequency electrical noise before power reaches connected audio or AV equipment. It can block up to 1.2V, or 1200mV, of DC offset. How many components can be connected to the DC Block 6? The unit provides six IEC outputs, allowing up to six compatible components to be connected simultaneously as long as the individual and total current limits are observed. What is the maximum load of the DC Block 6? Audiolab specifies a maximum of 8 amps for each individual IEC connection and a maximum combined load of 10 amps across the complete DC Block 6. Does the DC Block 6 also filter mains noise? Yes. In addition to blocking DC offset, the DC Block 6 contains a high-frequency filtering circuit designed to suppress RFI and EMI contamination and reduce both common-mode and differential-mode noise.
