How to Install the Optional
Plug-in Board
A variety of optional Plug-in boards sold separately let you
expand the voice library of your instrument. The S90 ES
provides three slots behind the rear panel for the Plug-in
Boards, allowing you to install up to three board to the
instrument. For details about the Plug-in Boards which can
be used with the S90 ES, see page 99.
n The Vocal Harmony Plug-in board (PLG100-VH) can be installed
only to slot 1.
n The Multi part Plug-in Board (PLG100-XG) can be installed only to
slot 3.
n The Single Part Plug-in boards can be installed to any of the three
slots.
1 Turn the S90 ES’s power off, and disconnect the AC
power cord. Also, make sure to disconnect the S90
ES from any other external devices.
2 Remove the large screw from the expansion bay
cover on the rear panel using a Phillips screwdriver.
Keep the removed screw in a safe place. Be careful not to
misplace any of the screws since all of them are used.
3 Remove the ribbon cables that are to be connected
to the Plug-in board from the inside of the S90 ES.
The slots are assigned to the color-coded cables as
follows: Slot 1 — orange, Slot 2 — yellow, Slot 3 — green.
4 Insert the board along the guide rails about two-
thirds of the way inside the S90 ES, with the
connector side face up and toward you.
5 Insert the Plug-in board the rest of the way into the
expansion bay.
n The Vocal Harmony Plug-in Board (PLG100-VH) can be installed
only to slot 1. It cannot be installed to slot 2 or 3.
