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.

A Tour of the GRIP
GAIN REDUCTION LED Meter
The red LED meter displays the amount of gain reduction applied by the bass limiters. An increase in gain reduction � by turning the BASS DRIVE Knob clockwise - will cause the meter to light from right to left.

BASS LEVEL Knob
This knob adjusts the level of the frequencies that fall below the crossover point set by the XOVER knob, except for the sub-bass.
BASS LEVEL LED Meter
This meter indicates the level of the GRIP�s main output signal. As you increase the level by turning the BASS LEVEL knob clockwise, this meter lights amber from left to right.
LO CUT Knob
This adjusts the cutoff frequency of a steep (6-pole) highpass filter, effectively limiting the lowest frequencies that the GRIP can output. The unit will output only those frequencies that are higher than the one set with the LO CUT knob. This knob is useful for protecting your speakers from ultra-low frequencies that may cause damage.
OUTPUT Knob
This knob controls the level of the GRIP�s total output signal from both the bass and sub-bass channels.
BYPASS Button
When you activate this button, the audio signal bypasses the Grip without being processed. This is useful when you want to compare the processed signal with the unprocessed signal. This button lights red when you enter BYPASS mode.
