Appendix: Parameter Lists
01V96i—Reference Manual
EXPAND
An expander attenuates signals below a specified THRESHOLD by a specified RATIO.
Parameter
Range
Description
THRESHOLD (dB)
–54.0 to 0.0 (541 points)
This determines the level of input signal required to
trigger the expander.
RATIO
1.0:1, 1.1:1, 1.3:1, 1.5:1,
1.7:1, 2.0:1, 2.5:1, 3.0:1,
3.5:1, 4.0:1, 5.0:1, 6.0:1,
8.0:1, 10:1, 20:1,
:1
(16 points)
This determines the amount of expansion.
ATTACK (ms)
0–120 (121 points)
This determines how soon the expander returns to
its normal gain once the trigger signal level exceeds
the threshold.
RELEASE (ms)
44.1kHz: 6 ms – 46.0 sec
48kHz: 5 ms – 42.3 sec
88.2kHz: 3 ms – 23.0 sec
96kHz: 3 ms – 21.1 sec
(160 points)
This determines how soon the signal is expanded
once the signal level drops below the threshold.
The value is expressed as the duration required for
the level to change by 6 dB.
OUT GAIN (dB)
0.0 to +18.0 (180 points)
This sets the expander’s output signal level.
KNEE
Hard, 1–5 (6 points)
This determines how expansion is applied at the
threshold. For higher knee settings, expansion is
applied gradually as the signal falls below the speci-
fied threshold, creating a more natural sound.
