Connections
Before connecting phones or other external equipment, be
sure to first turn down the volume settings of the keyboard
and the connected equipment. You can then adjust volume to
the desired level after connections are complete.
Rear Panel
J Connecting Phones 1
Connecting phones cuts off output from the keyboard’s built-
in speakers, so you can play even late at night without
disturbing anyone.
J Audio Equipment 2
Connect the keyboard to a audio equipment using a
commercially available connecting cord with a standard plug
on one end and two PIN plugs on the other end. Note that the
standard plug you connect to the keyboard must be a stereo
plug, otherwise you will be able to output only one of stereo
channels. In this configuration, you normally set the input
selector of the audio equipment to the terminal (usually
marked AUX IN or something similar) where the cord from
the keyboard is connected. See the user documentation that
comes with your audio equipment for full details.
J Musical Instrument Amplifier 3
Use a commercially available connecting cord to connect the
keyboard to a musical instrument amplifier.
• Be sure to use a connecting cord that has a stereo standard
plug on the end you connect to the keyboard, and a
connector that provides dual channel (left and right) input to
the amplifier to which you are connecting. The wrong type of
connector at either end can cause one of the stereo channels
to be lost.
• When connected to a musical instrument amplifier, set the
volume of the keyboard to a relatively low level and make
output volume adjustments using the amplifier’s controls.
Connection Example
• You can also connect the keyboard to a computer or
sequencer. See “MIDI” on page E-75 for details.
You can connect an optional sustain pedal (SP-3 or SP-20) to
the SUSTAIN/ASSIGNABLE JACK terminal to enable the
capabilities described below.
For details on how to select the pedal function you want, see
“Changing Other Settings” on page E-66.

SUSTAIN/ASSIGNABLE JACK Terminal
J Sustain Pedal
• With piano tones, depressing the pedal causes notes to
linger, much like a piano’s damper pedal.
• With organ tones, depressing the pedal causes notes to
continue to sound until the pedal is released.
J Sostenuto Pedal
• As with the sustain pedal function described above,
depressing the sostenuto pedal causes notes to be
sustained.
• This difference between a sostenuto pedal and sustain
pedal is the timing.
• With a sostenuto pedal, you press the keys and then
depress the pedal before you release the keys. Only the
notes that are sounding when the pedal is depressed are
sustained.
J Soft Pedal
Depressing the pedal softens the sound of the notes being
played.
J Rhythm Start/Stop Pedal
In this case, the pedal performs the same functions as the
START/STOP button.
Use only the accessories and options specified for this
