For private practicing and playing without
disturbing others, connect a set of stereo
headphones to the rear panel PHONES/OUT-
PUT jack. Sound from the built-in speaker
system is automatically cut off when you
insert a headphone plug into this jack.
CAUTION
Do not use headphones for a long time at high
volume levels. Otherwise, you may damage
your hearing.
Though the EZ-30 is equipped with a built-in
speaker system, you can also play it through an
external amplifier/speaker system. First, make
sure the EZ-30 and any external devices are
turned off, then connect one end of a stereo
audio cable to the LINE IN or AUX IN jack(s) of
the other device and the other end to the rear
panel PHONES/OUTPUT jack on the EZ-30.
CAUTION
To prevent damage to the speakers, set the vol-
ume of the external devices at the minimum
setting before connecting them. Failure to
observe these cautions may result in electric
shock or equipment damage. Also, be sure to
set the volumes of all devices at their mini-
mum levels and gradually raise the volume
controls while playing the instrument to set the
desired listening level.
This feature lets you use an optional foot-
switch (Yamaha FC4 or FC5) to sustain the
sound of the voices. The footswitch func-
tions the same way as a damper pedal on an
acoustic piano - press and hold down the
footswitch as you play the keyboard to sus-
tain the sound.
•Make sure that the footswitch plug
is properly connected to the SUS-
TAIN jack before you turn on the
power.
•Do not press the footswitch while
turning the power on. Doing this
changes the recognized polarity of
the footswitch, resulting in
reversed footswitch operation.
The EZ-30 also features MIDI terminals,
allowing you to interface the EZ-30 with
other MIDI instruments and devices. (For
more information, see page 78.)
•Special MIDI cables (sold sepa-
rately) must be used for connecting
to MIDI devices. They can be
bought at music stores, etc.
•Never use MIDI cables longer
than about 15 meters. Cables
longer than this can pick up noise
which can cause data errors.
