With a slow attack time, however, ducking appears to fade in the signal. Too fast an attack time may sound abrupt. +20 +10 0 Output Level (dB) ­10 Threshold = ­20dB ­20 ­30 ­40 ­50 ­60 ­70 Range = ­30dB ­70 ­60 ­50 ­40 ­30 ­20 ­10 Input Level (dB) 0 +10 +20 HOLD-- This determines how long ducking remains active once the trigger signal has fallen below the threshold level. DECAY--This determines how soon the Ducker returns to its normal gain once the trigger signal level drops below the threshold. DME32--Owner's Manual Dynamics 135 Expander & Stereo Expander An expander essentially "stretches" a signal's dynamic range, thereby reducing low-level signals such as noise, effectively increasing the signal-to-noise ratio. Two expander components are available: a single-channel Expander and a Stereo Expander. They can be self-triggering or externally triggered via the sidechain input. The Expander component features one input, one output, and a sidechain input. The Stereo Expander component features two inputs, two outputs, and a sidechain input. The Expander control window features a gain reduction (GR) meter, expander curve, output level meter, and expander controls. The Stereo Expander control window features a gain reduction (GR) meter, expander curve, output level meters, and expander controls. The gain reduction (GR) meter displays the amount of gain reduction being applied by the Expander. The expander curve displays the effect of the Expander. The vertical axis corresponds to the output signal level, while the horizontal axis corresponds to the DME32--Owner's Manual 136 Chapter 8--Component Guide Part I input signal level. A 45-degree line means that the input signal level equals the output signal level, in other words, the Expander is having no effect. The output meter displays the level of the output signal.

On the Stereo Expander, the trigger signal is derived by mixing the signals from both inputs, so the higher of the two input signals will activate the Expander. When SIDECHAIN is on, the Expander is triggered by the signal connected to the sidechain input. THRESHOLD--This determines the level of the trigger signal required to activate the Expander. Trigger signals above the threshold cause the Expander to pass the input signal through unaffected. Trigger signals below the threshold level cause the Expander to expand the input signal by the amount specified using the Ratio parameter. RATIO--This determines the amount of expansion. That is, the change in output signal level relative to the change in trigger signal level. For a 2:1 ratio, for example, a 5 dB change in trigger level (below the threshold) results in a 10 dB change in output level. [. . . ] Linkwitz-Riley--This filter offers slopes of 12 dB, 24 dB, 48 dB, etc. When the output signal from its LPF and HPF are combined, the gain over the entire range is flat. Like the Butterworth filter, it has a flat pass band. The gain at the cutoff frequency is -6 dB. [. . . ]
