DC Block

About the DC Block

The Audiolab DC Block is a compact dual-purpose mains accessory that blocks or cancels DC voltage on the AC supply, correcting DC offset and helping prevent transformer hum and vibration. It also incorporates an audio-grade filtering circuit to reduce common-mode and differential-mode RFI/EMI noise. Designed for a single audio or AV component, it is particularly suited to integrated or power amplifiers. It is available in black or silver.
