Dynamics Parameters - Yamaha M7CL Owner's Manual

Input channels provide DYNAMICS section 1 and DYNAMICS section 2. Output channels provide
DYNAMICS section 1.
An input channel's DYNAMICS section 1 provides the following four types:
GATE, DUCKING, COMPRESSOR, and EXPANDER.
An input channel's DYNAMICS section 2 provides the following four types:
COMPRESSOR, COMPANDER-H (Compander Hard), COMPANDER-S (Compander Soft), and DE-ESSER.
An output channel's DYNAMICS section 1 provides the following four types:
COMPRESSOR, EXPANDER, COMPANDER-H (Compander Hard), and COMPANDER-S (Compander Soft).
■ GATE
A gate attenuates signals below a set THRESHOLD level by a specified amount (RANGE).
Parameter
THRESHOLD (dB) –72 to 0 (73 points)
RANGE (dB) –∞, –69 to 0 (71 points)
ATTACK (ms) 0–120 (121 points)
44.1kHz: 0.02 ms – 2.13 sec
HOLD (ms)
48kHz: 0.02 ms – 1.96 sec (160 points)
44.1kHz: 6 ms – 46.0 sec
DECAY (ms)
48kHz: 5 ms – 42.3 sec (160 points)

■ DUCKING
Ducking is commonly used for voice-over applications in which the background music level is reduced automatically when an
announcer speaks. When the KEY IN source signal level exceeds the specified THRESHOLD, the output level is attenuated by a
specified amount (RANGE).
Parameter
THRESHOLD (dB) –54 to 0 (55 points)
RANGE (dB) –70 to 0 (71 points)
ATTACK (ms) 0–120 (121 points)
44.1kHz: 0.02 ms – 2.13 sec
HOLD (ms)
48kHz: 0.02 ms – 1.96 sec (160 points)
44.1kHz: 6 ms – 46.0 sec
DECAY (ms)
48kHz: 5 ms – 42.3 sec (160 points)

Dynamics Parameters

Range
This determines the level at which the gate effect is applied.
This determines the amount of attenuation when the gate closes.
This determines how fast the gate opens when the signal exceeds the threshold
level.
This determines how long the gate stays open once the trigger signal has fallen
below the threshold.
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.

THRESHOLD
Range
This determines the level of trigger signal (KEY IN) required to activate ducking.
This determines the amount of attenuation when ducking is activated.
This determines how soon the signal is ducked once the ducker has been triggered.
This determines how long ducking remains active once the trigger signal has fallen
below the THRESHOLD level.
This determines how soon the ducker returns to its normal gain once the trigger sig-
nal level drops below the threshold. The value is expressed as the duration required
for the level to change by 6 dB.
