Connecting Headphones (Figure
1
)
Connecting headphones cuts off output from the keyboard’s
built-in speakers, so you can play even late at night without
disturbing anyone.
Audio Equipment (Figure
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.
Musical Instrument Amplifier (Figure
3
)
Use a commercially available connecting cord to connect the
keyboard to a musical instrument amplifier.
NOTE
• 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.

keyboard. For details, see “Using a Microphone for Sing
Along” on page E-26.
