2HP DC Blocker / Active AC Coupler

Keep your patches clean and stable with the Slimline DC Blocker, a compact 2HP Eurorack utility designed to remove unwanted DC offsets from audio, sub-audio and CV signals. It helps recover headroom, reduce clicks and pops, and keeps downstream modules such as mixers, VCAs, filters, compressors and waveshapers working in a predictable way.

The module provides four independent active AC-coupled channels with unity gain. Its Butterworth high-pass topology is designed to stay transparent in the passband while blocking unwanted DC components. Buffered outputs with low output impedance make the behavior consistent even with longer patch cables or more complex signal chains.

Two channels are optimized for high fidelity with a very low cutoff frequency, while two fast-settle channels are useful when offsets need to disappear more quickly after saturation, distortion, wavefolding or other processing stages.
