Connections
Connecting a Pair of Headphones
Plug a pair of standard stereo headphones in the PHONES/OUTPUT
jack.
Turn on the Phones Sense.
Press and hold [FUNCTION], then press the [F7] key to turn on the
Phone Sense function. When headphones are connected, the internal
speakers system will be muted. Sound can only be heard from the
headphones.
Turn off the Phone Sense.
Press and hold [FUNCTION], then press the [F#7] key to disable the
Phone Sense function. When headphones are connected, the sound
can be heard from the headphones and speakers.
Note:
To avoid the risk of hearing loss, do not use headphones at high
volume levels for a long period of time.
Connecting an Audio Equipment
The PHONES/OUTPUT jack delivers the output of the instrument to
external audio equipment such as a keyboard amplifier, stereo sound
system, mixing console, or recording interface.
Use an audio cable to connect the PHONES/OUTPUT jack of the
instrument to the INPUT jack of the external audio equipment.
Notes:
1. Turn off the power to all devices before connecting or disconnecting
external equipment.
2. To avoid damaging the speakers, set the master volume level to
minimum before turning on the power.
Connecting a Pedal
Plug the included pedal into the SUSTAIN jack. When you step on the
pedal, the notes you play on the keyboard will have a longer sustain.
Connecting a Computer
Use a standard USB cable to connect the USB jack of the instrument
to the USB port of a computer.
With USB, you can save the MIDI data played on the keyboard to the
computer or use the instrument to play back the MIDI data played on
the computer.
Note:
Do not set the USB MIDI device to be both input and output simultane-
ously when configuring the software on your computer. Otherwise, the
sound will be overlapped when playing the keyboard.
