Dynamics Plug-Ins : Dynamics III : Expander/Gate III : Expander/Gate III Threshold Control

Expander/Gate III Threshold Control
The Threshold (Thresh) control sets the level below which an input signal must fall to trigger expansion or gating. Signals that fall below the threshold will be reduced in gain. Signals that are above it will be unaffected.
An orange arrow on the Input meter indicates the current threshold, and can also be dragged up or down to adjust the threshold setting.
 
The Dynamics Graph display also shows the threshold as an orange vertical line.
 
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.
