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.

MASTER SECTION DESCRIPTION
6 DIGITAL DELAY The signal from the input channels, processed by the built-in digital delay will feed to the master output. There are three knobs here to control the effect of digital delay. LEVEL This knob adjusts the mix level of the effect sound. TIME This knob adjusts the internal time of the delays; turn to the right to increase the interval time between two delays. REPEAT To increase the rate of the delays, turn this knob to the right. You will hear the signal repeat at a faster rate.
7 TAPE IN CONTROL This knob adjusts the level of signal from the Tape In to the Main bus.
8 MASTER CONTROL This adjusts the final level of the Main bus. It controls the Main bus signal which is output to the speakers.
9 TAPE IN AND REC OUT The TAPE IN sockets allow cassette recorders or CD players to be added to the Main output. The RECORD OUTPUT, with RCA phono sockets, provides signal output to a cassette deck and home audio equipment. The nominal output level and impedance are -10dBV/600ohms.
