Audiolab DC Block 6 Direct Current Blocker – Black

3 Year Warranty (Subject To Registration) Black Has Been Designed To Improve The Quality Of AC Electricity That Feeds Audio & AV Systems Mains Electricity Has A Fundamental Influence On The Audio Signal As It Passes Through A System, From Source To Amp To Speakers. The Mains Supply In A Typical Dwelling Is Subject To Interference Induced By A Range Of Issues, Causing AC Waveform To Distort Before It Reaches The Component This Creates Noise In The Audio Signal, Which Degrades Sound Quality – A Situation That Continues To Worsen With More & More Electrical Devices Being Added To The Home Mains Supply One Common Issue Is ‘DC On The Mains’ – A Problem 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 & Negative Phases. However, The Presence Of ‘Asymmetrical Loads’ – Myriad Household Devices That Use The AC Energy Available In The Mains Cycle Unevenly, From Dimmer Switches To Kitchen Appliances To Computer Power Supplies – Causes The Waveform To Become Offset, Resulting In The Presence Of DC Voltage On The AC Supply The AC Transformers Commonly Used In 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 & May Cause Audible Mechanical Vibration The Audiolab DC Block 6 Is a 6-Way Solution For This All-Too-Common Problem By Blocking, Or Cancelling, DC Voltage Found Within The Mains Supply, The Audiolab DC Block 6 Corrects The DC Offset & Rebalances The Mains Sine Wave. 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) & Common-Mode Noise (Aggravated By Airborne Interference From Phones, WiFi Networks & Bluetooth) Simple Set-Up The DC Block 6 Has 1 Single Mains Input & Offers 6 IEC Outlets For The Mains Power Supply Of Your Audio System Components (Cables Included) Perfectly Sized To Match Audiolab Components & To Easily Fit Into A Typical Hi-Fi Shelf/Rack System, the DC Block 6 Also Features a OLED 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, & RF Interference Offers Radical Improvement In Mains Quality, Transformer & Power Supply Performance, & Therefore Sound Quality Amplifier Compatibility: Max Total Loading 10A Audio Power: Each Receptacle Loading 8A Height: 78.4mm, Width: 444mm, Depth: 306.4mm Weight: 4.6Kg Reserve Now
