Dynamics Parameters
4 RIVAGE PM series Data List
■ GATE
A gate attenuates signals below a set THRESHOLD level by a specified amount (RANGE).
■ DE-ESSER
This detects and compresses only the sibilants and other high-frequency consonants of the vocal.
■ EXPANDER
An expander attenuates signals below a specified THRESHOLD by a specified RATIO.
Parameter Range Description
THRESHOLD –72.0 to 0.0 (dB)
This determines the level at which the gate effect is
applied.
RANGE –∞, –72.0 to 0.0 (dB)
This determines the amount of attenuation when the
gate closes.
ATTACK 0 to 120 (msec)
This determines how fast the gate opens when the
signal exceeds the threshold level.
HOLD 0.02m to 1.96 (sec)
This determines how long the gate stays open once
the trigger signal has fallen below the threshold.
DECAY 3.34m to 42.7 (sec)
This determines how fast the gate closes once the
hold time has expired. The value is expressed as the
duration required for the level to change by 6 dB.
Parameter Range Description
THRESHOLD –60.0 to 0.0 (dB) Threshold level at which the de-esser effect applies.
FREQUENCY 800 to 16.0k (Hz) Cutoff frequency of the filter used to detect the high frequencies.
TYPE BELL, H.SHELF Type of filter used to detect the frequency band.
Q (TYPE BELL) 25.0 to 0.5 Q (steepness) of the filter when TYPE is BELL.

Parameter Range Description
THRESHOLD –60.0 to 0.0 (dB)
This determines the level of input signal required to
trigger the expander.
RATIO 1:0 to ∞:1 This determines the amount of expansion.
ATTACK 0 to 120 (msec)
This determines how soon the expander returns to its
normal gain once the trigger signal level exceeds the
threshold.
RELEASE 3.34m to 42.7 (sec)
This determines how soon the signal is expanded
once the signal level drops below the threshold. The
value is expressed as the duration required for the
level to change by 6 dB.
OUT GAIN –20.0 to +40.0 (dB) This sets the expander’s output signal level.
KNEE Hard, Soft-1, Soft-2, Soft-3, Soft-4, Soft-5
This determines how expansion is applied at the
threshold. For higher knee settings, expansion is
applied gradually as the signal falls below the
specified threshold, creating a more natural sound.
