Dynamics Control Ranges

Section	Threshold	Ratio/Range	Attack	Hold	Release
GATE	-80 – 0dB	-80 – 0dB	5us* – 26ms	10ms – 10s	7.8 – 519ms
EXPANDER	-60 – 0dB	-80 – 0dB	26us – 104ms	10ms – 20s	5.2 – 519ms
COMPRESSOR	-60 – 0dB	1:1 – Limit	519us – 52ms	10ms – 30s	52ms – 3.1s
LIMITER	-60 – 0dB	–	100us – 500ms	50ms – 10s	100ms – 10s

All values in the table are referenced to full scale and time constants apply to a 10dB gain change. Therefore the time value marked * denotes a calculated value for 10dB gain change, since the true figure is 40dB gain change in 20.8us. (Sample rate at 48kHz)

 

Side-Chain EQ Control Ranges

Section	Gain	Frequency	Q/Slope	Overshoot
LF Peak/Shelf	+/-20dB	20Hz – 1kHz	0.5 – 16	0 – 50% (Q adjust in Shelf)
HF Peak/Shelf	+/-20dB	1KHz – 20Khz	0.5 – 16	0 – 50% (Q adjust in Shelf)
