[AUX IN] jack—Listen to a portable music

player using the digital piano’s speakers

By connecting the headphones jack of an audio device

such as a portable music player to the digital piano’s

[AUX IN] jack using a stereo audio cable as shown

below, you can route audio from that device to the

built-in speakers.

[L/L+R] and [R] AUX OUT jacks—Listening to

the digital piano using external speakers

If you need to raise the volume of the digital piano

beyond the limit of the built-in speakers, you can con-

nect it to powered speakers using the [L/L+R] and [R]

AUX OUT jacks. The volume of the sound output via

these jacks can be adjusted using the instrument’s

[MASTER VOLUME] slider. If necessary, you can

turn off your digital piano’s built-in speakers when

using external speakers. Refer to page 44 for details.

With your digital piano’s [USB TO HOST] terminal con-

nected to a computer using a USB cable, you can exchange

MIDI data with the computer and also get much more out

of music software running on it. For details on how to con-

nect to a computer and exchange data, please refer to the

• When connecting other equipment to your digital piano, ensure that all devices are turned off first. In addition, be sure to set all volume levels

to minimum (0) before turning devices on or off. Failure to observe these precautions can lead to electric shock, hearing damage, or equip-

ment damage.

• In order to avoid damaging an audio device when you want to listen to it using the digital piano’s built-in speakers, be sure to turn on the

audio device first, followed by the digital piano. In addition, remember to always turn off the digital piano before the audio device.

CAUTION

NOTICE

Connecting audio equipment

• Using the corresponding Function parameter (page 40), you can specify whether

or not the volume of audio output via the AUX OUT jacks will be adjustable using

the [MASTER VOLUME] slider.

• Select cables and plugs with the lowest resistance possible.

• You should never directly or indirectly connect the digital piano’s AUX OUT jacks

to the [AUX IN] jack. For example, if you have connected the AUX OUT jacks to

powered speakers or the like, you should never route sound from the speakers

back to the digital piano’s [AUX IN] jack.

• Use only the [L/L+R] AUX OUT jack if you wish to output the digital piano’s

sound in mono.
