Connections

Phones/Output Terminal

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.

Connecting Phones (Figure 1)
Connecting phones 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.
* 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.

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.

Microphone Jack

You can connect a commercially available microphone to the
microphone jack and sing along with notes played on the
keyboard. For details, see "Using the Microphone Jack" on
page E-16.
