This is the correct representation of the DB25 input on the H9000, however, you would need to ground the cold pins when using an unbalanced input. Also, you may not be able to connect this pickup directly to the H9000’s inputs without a preamp or buffer depending on the output level.
There is another H9000 user who has been using it with hexaphonic pickups, I will send him a link to this thread and see if he has any suggestions for your setup.
