First there are ten parametric EQ buttons plus the high pass filter;-
As you can see there are a number of colour variations for these buttons. Unused bands are pale blue until they are selected for
editing by clicking on them in which case the colour goes to a brighter blue and the image shows the button depressed. Unused
is defined as the gain left at 0dB. A red button indicates that the band has been bypassed, irrespective of whether any gain
change has been made. Bypassed bands will change to a pale red when selected. Green buttons indicate a band that has either
cut or boost applied, these will go a pale green when selected. Note that the high pass filter is always active so will always appear
green.
Next there are the zone buttons;-
In this example the array has three zones with zone 1 selected. As well as individual gain as already discussed, zones each have
completely independent PEQ to allow precise adjustment, most commonly used with the MLD which often requires a different
equalisation to the rest of the array. Clicking on the zone number brings up the PEQ page for that zone. If the array has not been
divided into zones there will just be one button with a number 1, essentially the entire array is a single zone.
The graphic view of the equalisation is a relatively standard frequency response graph;-
The horizontal axis is frequency in Hertz from 20Hz to 20KHz, the vertical axis is gain from -18dB up to +18dB. Colour coding is
also used on the graph to represent the various modes.
First there are two traces, one red, and the other blue. The red trace is the response of the band that is currently selected; the
blue trace is the overall response of the entire PEQ.
Each small rectangle represents the position of each of the ten bands plus the high pass. For all of the EQ bands the position on
the horizontal represents the EQ centre frequency, the vertical position is the cut or boost applied. A blue rectangle is an active
EQ, a grey rectangle is an EQ that has been bypassed. The green rectangle identifies the cut-off frequency of the highpass filter.
