2.2.2Exp/Gate
Figure 26
The expander will add dynamic range to the input according to needs of the user. When the signal input is less than
“threshold”, the expander amplifies and outputs the signal input by the “ratio” set. Level output = threshold – (threshold –
level input)/ratio; when the signal input is more than “threshold”, it is output by 1:1. Level output = level input, when the
ratio is adjusted by the maximum value （∞）, the expander becomes a noise gate.
- Bypass : the signal input is bypassed and the signal will go directly to the next processing module. If it is pressed the
expander will not be enabled; otherwise, the expander will be enabled.
- Ratio: the dB of dynamically changed signal input of the expander/the dB of dynamically changed signal output of the
expander.
- Attack time : less than the time needed of the signal input of “threshold” of the expander from the entering into the
expanding status to output by the setting of expanding ratio.
- Release time: the time needed for the signal input returning to the original non-expanding status from the expanding
status.
- All reset: all parameters are reset to the factory settings.
