Thank you for having the manual I needed for an older model Aiwa stero I had found on Ebay --- I wanted the Aiwa because I had tapes and cd's but I did not have a manual as to how to operate the system... I found what I needed and it has enabled me to set the system up for my enjoyment.
I wished detailed information of the JBL S310 and here I found it! Very happy with the service from this site!

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.
