Graphical display and control
A graph displaying the compressor curve is located at the bottom of 130c variant and at the top of the graphical strip in the 130
dynamics module. The values for threshold (lower cross) and ratio (upper cross) can be modified from the graph, and appear in red
at the base of the relevant dial.
Multi-Channel Variants
In/Out (130c: five channels or more)
This switch changes the bar graph meters to display either the input or output levels. The modules display the input levels as default
and when the switch is activated (and illuminated) the output levels are displayed.
LFE (130c: 5.1/6.1/7.1)
If the user desires the LFE channel to be compressed, then activating (and illuminating) this switch places it into the compressor
path. All channels are compressed together.
Dynamics
De-esser
The de-esser section allows the user to remove excess sibilance from a vocal performance or, in expand mode, boost the selected
frequency band.
De-ess
Pressing the ‘De-ess’ switch inserts the de-esser into the signal path. Essentially, this is a narrow band filter- driven compressor or
expander. The dial on the right, labelled ‘Hz’, controls the frequency of the filter, ranging from 1kHz to 10kHz. The dial on the left
allows control of the compressor knee, with greatest compression occurring when fully anticlockwise (DS/- 1) and expanding
substantially when fully clockwise (EX/+1).
Lstn
Press the ‘Lstn’ (listen) switch to audibly monitor the signals that are triggering activation of the de-esser; this is the filter in the
de-esser panel, visibly displayed in the graph in the 2U space alongside (see Graphical display section). This provides the user with
more accurate control over de-essing, rather than struggling to hear the effect in a complex signal.
