IMPORTANT!
• Whenever connecting external equipment, first set the MAIN
VOLUME knob of the digital piano and the volume controller
of the external equipment to relatively low volume settings. You
can later adjust volume to the level you want after connections
are complete.
Connecting Headphones
Connect commercially available headphones to the digital piano’s
PHONES jacks. This cuts off the built-in speakers, which means
you can practice even late at night without disturbing others. To
protect your hearing, make sure that you do not set the volume
level too high when using headphones.

Connecting to a PEDAL Jack
Depending on the type of operation you want the pedal (SP-3) to
perform, connect the pedal’s cable to the digital piano’s PEDAL
DAMPER jack or PEDAL SOFT/SOSTENUTO jack. If you want
to use both jacks at the same time, you need to purchase another
optionally available pedal.
See “Using the Digital Piano’s Pedals” on page E-9 for information
about using a pedal.

Connecting an audio or musical
instrument amplifier
Connecting to an audio or musical instrument amplifier provides
even clearer, more powerful sound through external speakers.
IMPORTANT!
• The digital piano automatically adjusts sound output to optimize
for headphone output (when headphones are connected) or built-
in speaker output (when headphones are not connected). Note
that this feature also affects the sound output from the LINE
OUT R and L/MONO jacks.
Connecting to Audio Equipment 1
Use commercially available cables to connect the external audio
equipment to the digital piano’s LINE OUT jacks as shown in
Figure 1. R jack output is right channel sound, while L/MONO
jack output is left channel sound. It is up to you to purchase
connecting cables like the ones shown in the illustration for
connection of audio equipment. Normally in this configuration you
must set the audio equipment’s input selector to the setting that
specifies the terminal (such as AUX IN) to which the digital piano
is connected. Use the digital piano’s MAIN VOLUME knob to
adjust the volume level.
Connecting to a Musical Instrument
Amplifier 2
Use commercially available cables to connect the amplifier to the
digital piano’s LINE OUT jacks as shown in Figure 2. R jack output
is right channel sound, while L/MONO jack output is left channel
sound. Connecting to the L/MONO jack only outputs a mixture of
both channels. It is up to you to purchase connecting cables like
the ones shown in the illustration for connection of the amplifier.
Use the digital piano’s MAIN VOLUME knob to adjust the volume
level.
