Using The Compressor - Yamaha CS1D Operating Manual

CS1D Operating Manual (Basic Operation)

Using the compressor

By using the COMPRESSOR section of the SELECTED INPUT CHANNEL block, you can manually operate nearly all of
the compressor parameters.
Hint
The compressors provided by the PM1D system allow you to choose from three types: COMP (compressor),
EXPANDER, and COMPANDER. However, the choice of type cannot be made from the top panel. For this reason,
you must first load compressor data that uses the desired type from the library, and then use the SELECTED INPUT
CHANNEL block to adjust the parameters as necessary.
The COMPRESSOR section contains the following controls and functions.
COMPRESSOR FILTER [ON] switch and LED
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 by the [VALUE] indicator.
COMPRESSOR [LINK] switch and LED
This specifies whether compressor opera-
tion for pairable input channels will be
linked by the key-in signal (link=on) or
whether the compressors will operate
independently (link=off). (The LED will light
if link is on.) For details refer to "CS1D Ref-
erence Manual (Hardware)" p.26.
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 entering the compressor.
COMPRESSOR [GAIN] encoder and LED
This encoder sets the GAIN parameter of the
internal compressor. The approximate current
value is shown by the perimeter LEDs.
52
COMPRESSOR [RATIO] encoder and [VALUE] indicator
The [RATIO] encoder located at the right sets the ratio of the compressor.
The current value is shown by the [VALUE] indicator at left.
COMPRESSOR
COMPRESSOR [ON] switch and
LED
This switches the internal compres-
sor on/off.
COMPRESSOR FILTER [FREQUENCY]
encoder and [VALUE] indicator
Use the [ON] switch located at the left to
switch on/off the HPF or LPF placed
before the internal compressor, and use
the [FREQUENCY] encoder at the right to
set its cutoff frequency. The current value
is shown by the [VALUE] indicator.
The HPF and LPF cannot be used simul-
Hint
taneously. The selection of either HPF or
LPF is made in the display (IN GATE/
COMP function COMP PRM screen).
COMPRESSOR [ATTACK]/[RELEASE]
switches and LEDs
COMPRESSOR [WIDTH (dB)/KNEE]
encoder and [VALUE] indicator
If the compressor type is COMP or
EXPANDER
Use the [WIDTH (dB)/KNEE] encoder to
set the KNEE parameter of the COMP or
EXPANDER. (The [KNEE] LED will light.)
If the compressor type is COMPANDER
Use the [TIME] encoder to set the WIDTH
parameter of the COMPANDER.
COMPRESSOR [THR] encoder and LEDs
This sets the THRESHOLD LEVEL
parameter of the internal compressor.
The approximate current value is shown
by the perimeter LEDs.
