Audiolab DC-BLOCK 6 Six-Way DC Blocker

Audiolab DC-BLOCK 6 – Six-Way DC Blocker (Available in black or silver)

The ultimate solution against hum and interference

Whether it’s transformer hum, ground loop noise, or high-frequency interference – the Audiolab DC BLOCK 6 eliminates DC offset and filters power line noise for a cleaner signal path and more dynamic sound.

The quality of mains power has a fundamental impact on audio signals as they travel through a system from source to amplifier to loudspeakers. In a typical home, the power grid is subject to various interferences that distort the AC waveform before it reaches your components. This introduces noise into the audio signal and degrades sound quality – a problem that increases with the number of electrical devices connected to the mains.

One common issue is “DC on the mains” – a known cause of degraded audio performance, especially in amplifiers. In theory, the electricity supplied to our homes should be pure alternating current (AC), with a perfectly symmetrical sine wave alternating between positive and negative phases.

However, the transformers used in most home audio gear cannot tolerate significant levels of DC voltage without being affected. As little as 500 mV of DC – typical in household power – can saturate toroidal transformers (commonly found in amplifiers), leading to reduced performance and audible mechanical hum.

The Audiolab DC BLOCK 6 offers a six-way solution to this all-too-common problem.

It blocks DC from the AC power line, corrects DC offset, and restores a balanced AC sine wave. But eliminating DC is not its only benefit – the unit also includes a high-performance audio-grade filter stage that removes RFI/EMI interference from the mains power. This effectively reduces both differential-mode noise (caused by cheap switch-mode power supplies in many appliances) and common-mode noise (caused by airborne disturbances from phones, Wi-Fi, and Bluetooth).

Safety information — Audio Everywhere

These notes apply to all HiFi devices and accessories sold by us.

Electronic devices (amplifiers, streamers, CD players, turntables)

Operate only in dry, enclosed indoor spaces. Avoid moisture, direct sunlight and extreme temperatures. Use only the specified mains voltage — do not overload power strips. Do not switch on devices with damaged cables or housings. Keep ventilation slots clear: at least 10 cm distance from walls and other devices. Place stably and securely — no open liquid containers nearby. Keep out of reach of children and pets.

Speakers

Place on a stable surface or suitable stands. No moisture, no direct sunlight. Operate only with matching amplifiers and correctly polarised cables. Do not use as a storage surface. Keep out of reach of children and pets.

Cables (speaker cables, RCA, power cables)

Use only for the intended purpose. Always pull by the plug, never by the cable. Avoid kinks, sharp edges and pressure from heavy objects. Replace visibly damaged cables immediately. Keep out of reach of children and pets.

Accessories (adapters, mounts, cleaning agents, styli, headshells)

Use only according to the manufacturer's instructions. No aggressive cleaning agents, no damp environments. Store small parts safely due to choking hazard. Mount accessories correctly to avoid damage or malfunction.

General notes

Read the operating instructions before use. No unauthorised repairs or opening of devices. Always contact a specialist service for technical problems. We are happy to answer any questions about safe use at any time.
