1.6.3 Output Channel EQ ...............................................................
The EQ located in each output Channel is similar in operation to the input channel EQ, with the following exceptions:
Output channel EQs have either have 4 Bands of EQ and HPF/LPF (SD8,9,11) or eight bands – four pre-insert and four post-
insert (SD5,7,10). Buttons in the channel strip (pre-insert eq and post-insert eq) and in the EQ display (pre-insert bands
and post-insert bands) select which set of bands is assigned to the worksurface and display controls. All eight bands are
shown in the EQ graph, with the pre-insert bands shown in lighter shades than the post-insert bands.
The precision and classic buttons above the EQ bands only affect the four bands currently displayed, and not the full 8 bands
available. The pre-insert bands do not have dynamic EQ or bell-shelf switching – the bell button is only used for switching
between precision and classic Q shapes. (SD5,7,10)
1.6.4 Channel Dynamics ................................................................
The SD channel dynamics includes two dynamics modules. Module 1 is a fully configurable compressor which can be split into
three frequency bands or configured as a de-esser; Module 2 can function as a gate, a ducker, or a compressor, all with high-
and low-pass filtering on the key input.
The in-channel display is located below the eq display, with Module 2's controls shown below Module 1's. Each module can be
switched on by pressing the on/off switch in the upper left corner of its channel area. These buttons are grey when off and red
when on.
The display includes an input (In) meter and a gain reduction (GR) meter. The input meter has arrows to its right which display the
current threshold values for each module. Each arrow is distinguished by its colour, which matches its associated threshold pot.
When Module 1 is in Compressor or Multiband mode, threshold and gain pots, each with a value display in dB, are also shown in
the channel strip (when in Multiband mode, the threshold pot affects all bands and the mid band's value is displayed). The De-
esser only displays a threshold pot and its value. There is a threshold pot (with value display) shown for Module 2, with three
status indication lights shown when in Gate or Ducker mode.
1: Compressor
2: Gate 1: Multiband
2: Ducker 1: De-esser
2: Compressor
Pressing anywhere in either module area brings up the expanded dynamics display.
To switch each module between its three modes, touch the button on the left of its expanded display, marked comp/multi/
desser for Module 1, and gate/duck/comp for Module 2. Both modules can be switched on using the on button below their
