Progressive ratio which increases with the threshold level. Two ratio ranges, 1:1 to 20:1 or soft 1:1 to 2:1. Five RMS settings, fast to slow and an adaptive mode. Classic 160vu RMS mode. Blend control for easy parallel compression. Feed-forward or feed-back mode. The T-Komp has a unique design which offers a modern take on the old vari-mu ratio curve. The ratio is progressive and increases with the threshold level. To make the T-Komp more useful it has two ratio ranges. The first one goes up to 20:1, perfect for instrument tracking and smashing drums etc., the second, 2:1, is a more narrow range which makes it more suitable for bus compression. The T-Komp can be selected between feed-forward mode for a punchy, modern response or feed-back mode with a smoother, more musical response. The RMS detector has five settings, four from fast to slow where number four, the slowest, is similar to the old 160VU. The fifth position is a program dependent adaptive mode.

To prevent unnecessary low frequency distortion thecircuit acts slower for slow moving signals and faster for fast moving signals. The attack and release are locked in relationship to each other.
