Quarter Space (Pi): An example of quarter space would be with speakers mounted on stands in a corner, or on the meter
bridge against a wall or mounted on small stands or shelves against a wall. Also typical PC/Mac editing in a confined space
on a desk near a wall. This is usually also a close field situation. Follow the DIP settings below for Quarter Space and adjust
for the listening distance accordingly. Adjust the LF-Q settings to balance the system.

"Difficult Space" (pi/2): An example of a difficult space would be with speakers against a wall, mounted on the same surface
as the PC/Mac machine tilted upwards towards the listener with one or other (or both!) speakers in a corner. This is also a close
field situation and demands extreme EQ to make the speakers measure reasonably flat. Typical examples might be a mobile
or temporary sound booth set up during an outside broadcast or live field event. Follow the DIP settings in the diagram below
for "Difficult Space" for the speakers in corners and adjust for the listening distance accordingly. Adjust the LF-Q settings to
balance the system.
