An optional foot switch (FC4, FC5) can be connected here to act as a sustain
pedal.
An optional foot switch (FC4, FC5, etc.) can be connected here to perform the
function (hold on/off, portamento on/off, etc.) determined by the Assignable Foot
Switch setting of Utility mode.
A pair of stereo headphones can be connected here to monitor the combined
stereo sounds of outputs 1 and 2.
If the OUTPUT 2 L/R jacks are not plugged in, these jacks will output the com-
bined stereo signal from output group 1 and group 2. If the OUTPUT 2 L/R jacks
are plugged in, these jacks will output the sound from the group 1 stereo output.
If only the L/MONO jack is used, it will carry the combined output of L and R.
(Use the L/MONO jack if your mixer/amp system has only one input.)
These jacks output the sound from the group 2 stereo output. If your mixer/amp
system has four or more inputs, using both the OUTPUT 1 and the OUTPUT 2 jacks
will allow you to treat the two output groups in different ways, perhaps by pan -
ning them to different locations, or processing them through different external
effect devices.
There are five expansion memory slots behind the YAMAHA SY99 logo plate.
You can install optional expansion memory boards (model SYEMB05) in these
slots to expand the SY99's MDR/sample memory area to a maximum of
3 Mbytes. For details, refer to Memory expansion boards in the appendix (page
325).
Press to turn the power on or off. The front panel display will light when the
power is turned on.
Plug the power cable into an AC outlet of the correct voltage.
