WALL is a brickwall limiter with a detector that hears 1.5 milliseconds into the future, so gain is already coming down before a peak arrives — nothing passes the ceiling you set. CEIL sets that ceiling, REL sets how fast the gain recovers after each peak (5 to 500 ms), and DRIVE pushes up to eight times pre-gain into the wall when you want the whole program leaning on it. SOFT trades the hard clamp for a soft saturation knee at the ceiling.

A multi-LED gain-reduction meter shows exactly how hard the wall is working, moment to moment. The detector is patchable: feed DET IN a different signal and the wall reacts to that signal ahead of time — key the limiter from a kick while it limits a bass. DET also sends the reduction out as 0–5 V CV, so whatever the wall does to your level can duck, pump, or animate anything else in the patch. Full CV over CEIL, REL, and DRIVE.
