The Threshold (Thresh) control sets the level that an input signal must exceed to trigger compression or limiting. Signals that exceed this level will be compressed. Signals that are below it will be unaffected.
This control has an approximate range of –60 dB to 0 dB, with a setting of 0 dB equivalent to no compression or limiting. The default value for the Threshold control is –24 dB.
An orange arrow on the Input meter indicates the current threshold, and can also be dragged up or down to adjust the threshold setting.
This control ranges from –60 dB (lowest gain) to 0 dB (highest gain).
