unnecessary but trying to get the DSP to get the signal from hard avoid immediately to audience is expecting far too much, it is
much more realistic to keep the stage floor as hard avoid and the front of the stage and pit non audience.
You will also notice a pink area at the back of the stalls in our example. This indicates any part of the venue plane that is not in
line of site of the array, essentially in "shadow". In many venues, particularly theatre style rooms with one or more balcony, this
is very common and additional balcony fills may need to be deployed. You can of course close the Cover tab and return to the
Slice tab to try alternative array positions to try and minimise any such shaded areas if audience areas are affected. In our
example it is only under the balcony and on the rear wall at the back of the stalls that are not in line of site and so there is no
need for any remedial action.
Changing Plane Properties
On the right hand side of the window is the section for adjusting the plane line properties;-
Each plane between nodes needs to be adjusted individually, to do this, click on the required plane property first, and then select
the line you wish to change. For example, on our example, we want to make the balcony from hard avoid and under the balcony
non audience. As it’s the top button, let’s do the non audience first. Click on the Non audience button and then hover over the
planes, as you hover over each line you will see the feint dashed lines turn a bright white, thick dashed line. When you are over
the plane you need to change, under the balcony in this case, a single mouse click changes the plane colour to red. Now we can
do the same for the balcony front, click the Hard Avoid button and then select the small vertical balcony front which will change
to blue to show it is now hard avoid.
You can click on the Audience button to change any planes to audience but this is rarely required as long as you initially defined
the audience areas correctly in the Venue slice, you are more likely to have too many audience planes rather than not enough
although you may need to change a plane back to audience if you have accidentally changed it to something else. If you get
several wrong you can click on the Reset which returns all planes to the default that you started with.
Here is our example with all planes changed to what we need;-
