Accessory Jacks
■
Using Headphones• • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • •
For private practicing and playing without disturbing others, connect a set of ste-
reo headphones to the rear panel PHONES/OUTPUT jack. Sound from the built-
in speaker system is automatically cut off when you insert a headphone plug into
this jack.
■
Connecting a Keyboard Amplifier or Stereo System • • • • • • •
Though the EZ-150 is equipped with a built-in speaker system, you can also play
it through an external amplifier/speaker system. First, make sure the EZ-150 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-150.
■
Using a Sustain Footswitch • • • • • • • • • • • • • • • • • • • • • • • • •
This feature lets you use an optional footswitch (Yamaha FC4 or FC5) to sustain
the sound of the keyboard voice. This is used in the same way as a damper pedal
on an acoustic piano — press and hold down the footswitch as you play the key-
board to sustain the sound.
■
Using the MIDI Terminals • • • • • • • • • • • • • • • • • • • • • • • • • • •
The EZ-150 also features MIDI terminals, allowing you to interface the EZ-150
with other MIDI instruments and devices. (For more information, see page 54.)
• To prevent damage to the
speakers, set the volume of
the external devices at the
minimum setting before con-
necting 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 minimum lev-
els and gradually raise the vol-
ume controls while playing the
instrument to set the desired
listening level.
• Make sure that the footswitch
plug is properly connected to the
SUSTAIN jack before turning 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.
