154 Appendix: Parameter Lists EXPAND An expander attenuates signals below a specified THRESHOLD by a specified RATIO. Parameter Range THRESHOLD (dB) -54.0 to 0.0 (541 points) 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) ATTACK (ms) 0-120 (121 points) RELEASE (ms) OUT GAIN (dB) 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) 0.0 to +18.0 (180 points) KNEE Hard, 1-5 (6 points) Description This determines the level of input signal required to trigger the expander. This determines the amount of expansion. This determines how soon the expander returns to its normal gain once the trigger signal level exceeds the threshold. 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. This sets the expander's output signal level. This determines how expansion is applied at the threshold. For higher knee settings, expansion is applied gradually as the signal falls below the specified threshold, creating a more natural sound.
