Compressor Settings - Yamaha CS1D Owner's Manual

Compressor settings

You can use the COMPRESSOR section of the SELECTED OUTPUT CHANNEL block to manually control almost all of
the compressor parameters.
Hint
The compressors of the PM1D system allow you to select one of three types: COMP (compressor), EXPANDER, and
COMPANDER. However, it is not possible to select the type by operations on the top panel. For this reason, you
must first load compressor data of the desired type from the library, and then use the SELECTED OUTPUT CHAN-
NEL block to edit the parameters as desired.
Separate libraries are provided for the input channel compressors and output channel compressors. Compressor
data cannot be loaded into the opposite type of compressor.
The controls and functions of the COMPRESSOR section are shown below.
COMPRESSOR ATTACK/
RELEASE [TIME] encoder and
[VALUE] indicator
This sets the attack time/release
time of the compressor. Use the
switch located at the right to select
either ATTACK or RELEASE, and
use the [TIME] encoder to adjust
the value. The current value is
shown in the [VALUE] indicator.
COMPRESSOR [LINK] switch and
LED
This specifies whether the compres-
sors of adjacent odd-numbered
even-numbered MIX channels or
MATRIX channels will be linked by
the key-in signal (link=on), or whether
the compressors will operate with
independent key-in signals (link=off).
(The LED will light when link is on.)
For details refer to "CS1D Reference
Manual (Hardware)" ( p.61).
COMPRESSOR [GR] meter LEDs
These LEDs indicate the amount of gain reduc-
tion produced by the internal compressor.
COMPRESSOR [POST] meter LEDs
These LEDs indicate the level of the
signal after being processed by the
compressor.
COMPRESSOR [PRE CLIP] LED
This LED will light when the signal clips
before passing through the compressor.
COMPRESSOR [GAIN] encoder and LEDs
This sets the GAIN parameter of the internal
compressor. The approximate current value is
shown by the perimeter LEDs.
COMPRESSOR [RATIO]
encoder and [VALUE] indicator
Use the [RATIO] encoder located
at the right to adjust the ratio of
the compressor. The current
value is shown in the [VALUE]
indicator at left.
COMPRESSOR
COMPRESSOR [ON] switch and LED
This turns the internal compressor on/off.
Chapter 5. Basic operation for output channels
COMPRESSOR FILTER [ON] switch and LED
The [ON] switch located at the left is an on/off switch for the HPF or
LPF located before the internal compressor. The [FREQUENCY]
encoder at the right sets the cutoff frequency of this filter.
The current value is shown in the [VALUE] indicator.
The HPF and LPF cannot be used simultaneously. The selec-
Hint
tion of either HPF or LPF is made in the display (OUT COMP
function COMP PRM screen).
COMPRESSOR FILTER [FREQUENCY]
encoder and [VALUE] indicator
COMPRESSOR [THR] encoder and LED
Set the THRESHOLD LEVEL parameter
of the internal compressor. The approxi-
mate current value is shown by the perim-
eter LEDs.
COMPRESSOR [ATTACK]/
[RELEASE] switch and LED
COMPRESSOR WIDTH (dB)/
KNEE [TIME] encoder and
[VALUE] encoder
When the compressor type is
COMP or EXPANDER
use the [TIME] encoder to set the
KNEE parameter of the COMP or
EXPANDER. (The [KNEE] LED
will light.)
When the compressor type is
COMPANDER
use the [TIME] encoder to set the
WIDTH parameter of the COM-
PANDER.
