About dynamics
Input Channels feature two dynamics processors: Dynamics 1 and Dynamics 2. Output Channels feature one
dynamics processor. They include the following features:
(
You can select a dynamics function from six types, including GATE and COMP.
(
You can store two sets (A/B) of parameter settings.
(
You can use the parameter copy, paste, and library functions for Dynamics 1 and Dynamics 2 individually.
(
The key-in signals can be selected from other input or output channels, or from input patches.
The available dynamics types include:
LEGACY COMP
This is a standard compressor that has been equipped with many of Yamaha’s legacy
digital mixers, such as PM1D and PM5D.
COMP 260
This is an analog-flavored compressor built using Yamaha’s proprietory VCM (Virtual
Circuitry Modeling) technology. It emulates the characteristics of compressors and
limiters of the mid-1970s, which are now a standard for live sound reinforcement. This
compressor has faithfully modeled the VCA (Voltage Controlled Amplifier) circuit and
the RMS (Root Mean Square) detection circuit. Compression curve (Knee) can be set to
Hard, Medium, or Soft. Attack time and release time are variable. The preset settings
recreate the fixed value of the early legacy models. Designed under the supervision of
top SR engineers, the parameter effects have been optimized for live sound
reinforcement.
GATE
This dynamics type reduces the output by a fixed value (RANGE) when a signal smaller
than the THRESHOLD level is input.
DE-ESSER
This dynamics type detects only the sibilants and other high-frequency consonants of
the vocal, and compresses its bandwidth.
EXPANDER
This dynamics type reduces the output by a fixed ratio (RATIO) when a signal smaller
than the THRESHOLD level is input. DUCKING This dynamics type reduces the output
by a fixed value (RANGE) when a signal greater than the THRESHOLD level is input.
This is effective if you want to lower the volume level of background music using the
KEY IN SOURCE signal.
There are three ways to control the dynamics processors.
