Dear Technicsplayer

Thanks for your kind and prompt response to my KN7000 problem.

I have tried what you suggested but I discover that I still experience the very bazzy sound when I play any of the 12 black and white notes from the middle C of the board.

Maybe I should explain better my experience: When the APC button is switched off, the sound that I get across the breath of the keyboard is very crisp, wonderful and all that I could ask for in a keyboard. But I always require the accompaniment when I play. I need the APC to be switched on so I could use the accompaniment. However, when the APC button is switched on, any key that I play with my right hand from the Middle C white key all through the 12 white and black keys from Middle C upwards - they sound very deep and bazzy and they tend to drown any accompaniment that is on. After the 12th note from the Middle C, the keys start sounding beautiful and crisp again even with the APC on. Again, when I switch off the APC, those same notes/keys sound very good.

As you suggested, I went to the overall Equalizer and under FLAT, I set all the five Gain sliders to zero, changed all the 5 FC(Hz) settings to the minimum which is 40 each, and changed the four Q(Hz) settings also to their minimum which is 0.1. And when I tried playing with the APC on, there was no change at all. I tried switching OFF the equalizer, and still there was the same problem - very deep and bazzy sounds produced by any keys played with the 12 black and white keys from the Middle C upwards. I really need help to solve this problem. I believe there must be something to turn off or on, or something to adjust somewhere in order to solve this problem. But I don't know, and I therefore need your help and that of members of the Forum out there.

eanwhile, I need to mention that I have just discovered that my KN7000 is PAL ver 1.3. I have read in some other Forum postings about members updating to ver 1.6. I have not yet updated mine, and hope that it is not the reason that I have the problem.

I look forward to your kind and expert advice on this. Thank you and thanks to all you members of the Forum for all your help to fellow members.
