Compressor Section - Yamaha CS1D Owner's Manual

COMPRESSOR section

In this section you can make settings for the internal compressor.
All parameters can be controlled from the top panel, except for compressor library store/recall operations, compressor
type selection, and key-in signal selection.

1 COMPRESSOR [RATIO] encoder and [VALUE]
indicator
This sets the ratio of the internal compressor.
The range of settings is 1:1 – (16 steps) if COMP or
EXPANDER is selected as the compressor type, or
1:1–20:1 (15 steps) if COMPANDER is selected.
2 COMPRESSOR FILTER [FREQUENCY] encoder,
[VALUE] indicator, and [Hz]/[kHz] LEDs
This sets the cutoff frequency of the HPF or LPF that
is placed in the first stage of the internal compressor.
The adjustable range is 20 Hz – 20 kHz (121 steps).
The current value is shown by the [VALUE] indica-
tor. (Either the [Hz] or [kHz] LED will light to indi-
cate the units of the displayed value.)
The selection of HPF or LPF is made in the display
(IN GATE/COMP function COMP PRM screen).
Hint
HPF and LPF cannot be used simultaneously. When
COMP is selected as the type for the internal com-
pressor, selecting HPF will allow it to be used as a
"de-esser."

3 COMPRESSOR FILTER [ON] switch and LED
This is an on/off switch for the HPF or LPF that is
placed in the first stage of the internal compressor.
4 COMPRESSOR [ATTACK]/[RELEASE] switches
and LEDs
These switches select the function of the ATTACK/
RELEASE [TIME] encoder (5) located at the left of
the switches.
When the COMPRESSOR [ATTACK] LED is lit
The ATTACK/RELEASE [TIME] encoder will set the
ATTACK (attack time).
When the COMPRESSOR [RELEASE] LED is lit
The ATTACK/RELEASE [TIME] encoder will set the
RELEASE (release time).
5 COMPRESSOR ATTACK/RELEASE [TIME]
encoder, [VALUE] indicator, and [msec]/[sec] LEDs
According to the setting of the COMPRESSOR
[ATTACK]/[RELEASE] switch (4), this encoder
adjusts the ATTACK (attack time) or RELEASE
(release time) of the internal compressor.
The range of settings is 0 ms–120 msec for the attack
time, and 5 msec–42.3 sec for the release time (when
operating at 48 kHz).
The current value is shown in the [VALUE] indica-
tor. (Either the [msec] or [sec] LED will light to indi-
cate the units of the value.)
6 COMPRESSOR WIDTH (dB)/KNEE [TIME]
encoder, [VALUE] indicator, and [WIDTH]/
[KNEE] LEDs
The function of this encoder depends on the cur-
rently selected compressor type.
When the compressor type is COMP or
EXPANDER
Use the encoder to set the KNEE parameter of the
COMP or EXPANDER. (The [KNEE] LED will
light.)
You can select SF1–SF5 (SOFT 1–SOFT 5), or Hrd
(HARD).
When the compressor type is COMPANDER
Use the encoder to set the WIDTH parameter of the
COMPANDER.
The range is 1 dB–90 dB.
7 COMPRESSOR [GR] meter LEDs
This meter displays the amount of gain reduction
caused by the compressor.
