(A-9060DH/S, A-9120DH/S, A-9240SH)
When using the 9000 for the first time or any time the MODE selector is changed or a module is added or removed.

• Before making any changes, unplug the AC cord

• Decide on the MODE required, MATRIX or MIX

Insert the modules in the correct order:

• Plug the AC cord in

• The 9000 display will show, depending on the previous mode, “ERASE MIXER MEMO?” or “ERASE MATRIX MEMO?”

• Select ENTER on the front of the 9000

• The unit will power down and now be at factory reset condition.

• Select the POWER button on the front panel and you will now be ready to program.

TIP:
Please note that some programming information is contained in the modules and if a programmed module is moved from one 9000 to another, the programming will not change unless the above procedure is followed. This could happen if swapping a module into a slot that had already contained the same module type. Applying power may not recognize the changed module.

Unplugging the 9000 before making the above changes and re-initialization will help prevent unpredictable results.
