152 Appendix: Parameter Lists DUCKING Ducking is commonly used for voice-over applications in which the background music level is reduced automatically when an announcer speaks. When the KEY IN source signal level exceeds the specified THRESHOLD, the output level is attenuated by a specified amount (RANGE). Parameter Range Description THRESHOLD (dB) RANGE (dB) ATTACK (ms) HOLD (ms) DECAY (ms) -54.0 to 0.0 (541 points) -70 to 0 (71 points) 0-120 (121 points) 44.1kHz: 0.02 ms - 2.13 sec 48kHz: 0.02 ms - 1.96 sec 88.2kHz: 0.01 ms - 1.06 sec 96kHz: 0.01 ms - 981 ms (160 points) 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 the level of trigger signal (KEY IN) required to activate ducking. This determines the amount of attenuation when ducking is activated. This determines how soon the signal is ducked once the ducker has been triggered. This determines how long ducking remains active once the trigger signal has fallen below the THRESHOLD level. This determines how soon the ducker returns to its normal gain once the trigger signal level drops below the threshold. The value is expressed as the duration required for the level to change by 6 dB.
