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.
Text excerpt from page 7 (click to view)
HiDyn plus is a wideband compander system which compresses
the audio signal in the transmitter in a ratio of 2:1 (related to dB). In the receiver the signal is expanded in an identical and opposite way in a 1:2 ratio to restore the original signal. HiDyn plus has been specially developed for high quality radiomicrophone systems. Note: Only transmitters and receivers that are equipped with HiDyn plus can work correctly with each other. If non HiDyn plus equipment was mixed with HiDyn plus, the dynamic range would be drastically reduced and the transmission would sound blunt and flat. HiDyn plus is permanently active and cannot be switched off.
