• (A) – The level at which compression begins.
Threshold

Attack time
• (A to E) – The amount of compression applied to the signal.
Ratio
• (C to D) – The time it takes for the compressed signal to rise to the threshold level once the input level no longer exceeds the threshold.
Release time
11. – Sets the ratio of input level to output level when the signal exceeds the threshold.
