• Compressor: The compressor is a simple soft knee device shown in Figure 4-11
below. The threshold sets the level at which the compressor starts operating and
the ration sets the amount of compression.

There are 8 optional presets, where the power up preset is always configured as Preset
1. If no values are stored in Preset 1, then there will be no power up preset.
The presets operate by first selecting the desired preset number from the pull down
menu (see Figure 4-12 below).

Preset Selection
This will make the preset ‘active’ and the store‐recall buttons will be applied to those
presets, as follows…
• The “Store” button packs the DSP controls, GUI specific control DSP control
information, the CobraNet™ Setup page information and the ION settings and
sends the packet for storage in serial flash in a memory space allocated for the
chosen preset #. This process will take around 2 seconds
• The “Recall” button directs the HMI processor to retrieve the chosen preset #
data from serial flash and send the GUI specific DSP control information to the
GUI and then to parse through the saved CobraNet™ Setup page settings and
implement it via the HMI. The parsing process will take up to 10 seconds, due to
the time taken to restore data to the CobraNet™ flash.
Note 1: the changes are only seen in the GUI when that page is selected and the
operator requests updates for that page.
Note 2: If there is no preset in flash, then an error message will be shown.
