Overview

The Audiolab DC Block 6 is a specialized mains distribution and filtration component designed to eliminate the mechanical hum and sonic degradation caused by DC offset on the AC power line. Many home appliances leak small amounts of direct current into the household electrical circuit, causing transformer saturation in sensitive hi-fi equipment. By stripping away this DC component and providing high-frequency RFI/EMI filtration for six individual outlets, it restores quiet operation and increases the dynamic clarity of a complete audio system.

Simcoe Audio Video Insight

In our showroom, we often find that a customer's high-end amplifier is making a physical buzzing sound that has nothing to do with the speakers. This is almost always caused by "dirty" power. The DC Block 6 is a simple, effective remedy that physically quiets the transformers in your gear. Unlike some power conditioners that can squash dynamics by limiting current, this unit is designed to maintain the full speed and impact of your power amplifiers while cleaning up the background noise floor.

Pro Tip: Connect your most power-hungry components—like integrated or power amplifiers—to the first few outlets. Cleaning the DC offset at the source of your amplification provides the most immediate and noticeable improvement in soundstage depth and bass definition.

More Details

Why It Wins

• Transformer Hum Elimination: Targets the specific DC offset issue that causes physical transformer vibration and audible "buzz" from the chassis.
• Six Independent Outlets: Provides six IEC outlets to power your streamer, CD player, and amplifier from a single, tidy mains hub.
• Mains Signal Correction: Rebalances the AC sine wave to ensure that internal power supplies operate at their peak efficiency.

What Makes It Different

The DC Block 6 stands apart from standard power strips by focusing on the specific DC offset imbalance rather than just basic surge protection. It utilizes a dedicated circuit that blocks direct current without restricting the peak current delivery required by large high-fidelity components. It also incorporates a high-frequency filter to suppress RFI/EMI noise on the mains line, resulting in a lower noise floor for both digital and analog sources.

Technical Highlights

• One-Box Solution: Provides six high-quality outputs in a single chassis, matching the standard Audiolab 9000 and 7000 series aesthetic for seamless rack integration.
• High-Frequency Filtering: A dedicated filter circuit suppresses RFI/EMI noise on the mains line, helping uncover micro-details in the music that can otherwise be buried by electrical interference.
• Digital Voltage Display: Features a front-panel voltage display (with a rear-panel on/off switch) for easy monitoring of power stability.

Buyers Guide

Who This Is For

• The "Buzzy" Amp Owner: Anyone who can hear their amplifier's transformer hum from across the room or through the chassis.
• The System Builder: Ideal for users with multiple components who want a centralized, high-quality power distribution hub.

What To Pair It With

• Audiolab 7000 or 9000 Series Stack: The chassis is designed to match these components perfectly in both width and height for a professional-looking system.
• High-Quality Power Cables: To maximize the benefits of the filtered outlets, use shielded power cords from the DC Block 6 to your individual components.

Alternative Options

For users who only need to treat a single component, the Audiolab DC Block offers a compact, single-outlet solution. If your primary concern is high-voltage surges rather than DC offset or noise, a dedicated surge protector may be a more appropriate starting point. For those seeking the ultimate in power regeneration rather than filtration, specialized AC regenerators are available at a significantly higher price point.
