## Overview

The Audiolab DC Block is a compact, metal-encased mains filter designed to remove DC contamination and reduce transformer hum and RF interference from your AC power supply. Operating at 120 volts and supporting up to 600 watts, it enhances the performance of audio and AV systems by delivering cleaner power, resulting in clearer, noise-free sound reproduction.

## Description

The DC Block has been designed to improve the quality of AC electricity that feeds our audio and 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 the AC waveform to distort before it reaches each component. This creates noise in the audio signal, which degrades sound quality – a situation that continues to worsen as the electrical devices we use in our homes proliferate.
