Effects

Dynamics (Dynamic)

Appe

ndix

a: Envelope Select

When L/R Mix is selected for this parameter, the left and right
channels are linked to control the Limiter using the mixed sig-
nal. If L Only (or R Only) is selected, the left and right channels
are linked, and the Limiter is controlled via only the left (or
right) channel.

With L/R individually, the left and right channels control the
Limiter individually.

b: Ratio
c: Threshold [dB]
e: Gain Adjust [dB]

This parameter sets the signal compression “Ratio”. Compres-
sion is applied only when the signal level exceeds the “Thresh-
old” value.

Adjust the output level using the “Gain Adjust” parameter, since
compression causes the entire level to be reduced.

d: Attack
d: Release

These parameters set the attack time and release time. A higher
attack time will cause the compression to be applied more slowly.

f: Trigger Monitor

Setting this parameter On will cause the trigger signal to be out-
put, instead of the effect sound. Use this parameter to check the
trigger signal with EQ applied.

Usually, set this to Off.

f: Side PEQ Insert
g: Side PEQ Cutoff [Hz]
g: Q
g: Gain [dB]

These parameters are used to set the EQ applied to the trigger
signal.

The Limiter determines whether the compression is applied or
not, based on the post-EQ trigger signal. Setting the equalizer
allows you to set the Limiter to respond to any frequency band.

3: Multiband Limiter

This effect applies the Limiter to the low range, mid range, and
high range of the input signal. You can control dynamics for each
range to adjust the sound pressure of the low range, mid range,
and high range in a different way from the EQ.

e: Low Offset [dB]
f: Mid Offset [dB]
g: High Offset [dB]

These parameters set the gain of the trigger signal.

For example, if you do not want to apply compression to the high
range, reduce the “High Offset” value down below the “Thresh-
old” level. In this way, the high range limiter will not respond,
and compression will not be applied.
