Ground Control

There's low end you want to feel. Then there's low end you can't hear, can't use, and somehow still have to make room for. Ground Control helps you tell them apart.

Its dynamic subsonic limiter watches energy at the very bottom of the signal and steps in when that energy gets out of line. When the low end behaves, the limiter backs off. You can control stray excursions without automatically thinning every kick, bass note, and synth that passes through the plugin.

Call security only when you need it.

Set Threshold for the amount of sub-bass you're willing to tolerate. Release controls how the limiter recovers, from 50 to 1500 ms; Auto-Release adjusts the recovery to the material. A reduction meter shows when Ground Control is actually working, and Mix lets you blend the result with the original signal.

Use Dual mode when the left and right channels need independent treatment. Stereo mode shares detection across the pair, keeping the correction coordinated when a stable center matters.

For persistent trouble, close the floor.

The separate high-pass filter handles problems that don't come and go: room rumble, handling noise, turntable or transfer debris, and other low-frequency clutter. Set the corner anywhere from 5 to 60 Hz, select a 6, 12, or 24 dB/octave slope, or switch the filter Off. The dynamic limiter and the static filter have different jobs; you can use either one or both.

Zero should mean zero.

DC Removal is its own switch. It clears offset before the filter and limiter process the signal, without forcing you to choose a high-pass setting just to recenter the waveform.

Hear the part you took away.

Turn on Delta to listen to the material Ground Control is removing. If it's mostly rumble and subsonic wandering, good. If the bass line just walked out with it, ease back and try again. Your ears get the final vote; the meter is there to show its work.
