Dynamics Parameters - Yamaha CL1 Reference Manual

Dynamics Parameters

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 Range
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)

Description
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.

■ 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)

Range Description
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 signal level drops below
the threshold. The value is expressed as the duration
required for the level to change by 6 dB.
