Actually, I was looking for this information for 3 years!...now thanks to you, the manual is on my hands and of great help, cause I understand now where I was doing wrong connections and wires...excellent, I'll be back to you if in need, thank you.
This manual covers the main equipment features only. While it also includes the procedure for saving and loading from the now long obsolete memory cards it does not mention the how to operate with the optional floppy drive interface so I am still at a loss about how to use this! Note that there is a separate manual covering the MIDI interface and programming via the keyboard, not included in this download. You will also need to get hold of this if you want to use the MIDI interface properly. Basically there is little difference between this manual and the free to download manual for the similar PR60 model.
Good list of manuals. I found a very rare one and easily get. Should be promptly to download, as we must to wait hours even after confirmed payment.

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.
