Limiter graph
• (A) – The level at which limiting begins.
Threshold
• Attack time (B to C) – The time it takes for the limiter to reach maximum limiting after the input exceeds the threshold level.
• (A to E) – The amount of limiting applied to the signal.
Ratio

threshold.
• Vertical scale = dB
12. – Sets the ratio of input level change to output level change when the signal exceeds the threshold.
