Audiolab - DC Block 6 Power Distributor

Enhance the Quality of the Electricity Feeding Your A/V System: Six-Outlet Audiolab DC Block 6 Power Distributor Corrects DC Offset, Rebalances Mains Sine Wave, and Removes RFI/EMI Contaminants to Lessen Noise

Improve the quality of the noisy AC electricity coming into your system and help optimize up to six components with the Audiolab DC Block 6 power distributor. By blocking the unwanted DC voltage within the AC mains supply, this six-way solution corrects the DC offset and rebalances the mains sine wave. It further gives you the advantage of a high-performance filtering circuit that removes RFI/EMI contaminants from the mains, which reduces both differential-mode noise (exacerbated by cheap switch-mode power supplies used in home appliances) and common-mode noise (aggravated by airborne interference from phones, Wi-Fi networks, and Bluetooth).

Sold with six IEC C14 to C13 cables to connect its outlets to your gear, as well as a power cable to plug it into the mains, the 10.1-pound DC Block 6 also offers overload protection and is simple to use. Simply connect the supplied IEC cables from the DC Block 6 outputs to the desired units you wish to enhance. Then, connect the supplied power cord from the DC Block input to your AC outlet. Finally, put on some music, sit back, and savor the improvements in clarity, dynamics, detail, and more.

On the front panel, a user-defeatable voltage meter lets you keep tabs on what's happening, while on the back, a breaker button allows for quick recovery in the event of a circuit break. A three-year manufacturer warranty completes this audio-savvy value. Give us a call at 312-433-0200 to learn more. 

DC Mains Supply
One common issue is "DC on the mains," a problem 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. However, the presence of asymmetrical loads causes the waveform to become offset, resulting in the presence of DC voltage on the AC supply.

DC Voltage, and Its Challenge
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, adversely affecting sonic performance and possibly causing audible mechanical vibration. By blocking DC voltage found within the AC mains supply, DC Block 6 corrects the DC offset and rebalances the mains sine wave. It also contains a high-performance audio class filtering circuit that removes RFI/EMI contaminants from the mains supply.
