Using headphones cuts off output from the built-in speakers, 
which means you can practice playing even late at night 
without disturbing others.
 Be sure to turn down the volume level before connecting 
headphones.
 Headphones do not come with the Digital Keyboard.
 Use commercially available headphones.
 Do not listen to very high volume output over 
headphones for long periods. Doing so creates the risk 
of hearing damage.
 If you are using headphones that require an adaptor 
plug, make sure you do not leave the adaptor plugged 
in when removing the headphones.
Connecting an optionally available pedal let’s you perform 
pedal operations that add more versatility to your keyboard 
play. For information about the types of effects that can be 
applied by pressing the pedal, see “Ped.Assign  (Pedal 
Assign)” (page E-126).You can connect audio equipment or a music amplifier to the 
Digital Keyboard and then play through external speakers for 
more powerful volume and better sound quality.

Use commercially available connecting cords to connect the 
external audio equipment to the Digital Keyboard’s T-9 (LINE 
OUT) jacks as shown in Figure 
1. LINE OUT R jack output is 
right channel sound, while LINE OUT L/MONO jack output is 
left channel sound. It is up to you to purchase connecting 
cords 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 
Keyboard is connected. Use the L-2 (MAIN VOLUME) knob 
to adjust the volume level.
Use a commercially available connecting cord to connect the 
amplifier to either of the Digital Keyboard’s T-9 (LINE OUT) 
jacks as shown in Figure 
2. LINE OUT R jack output is right 
channel sound, while LINE OUT L/MONO jack output is left 
channel sound. Connecting to the LINE OUT L/ MONO jack 
only outputs a mixture of both channels. It is up to you to 
purchase a connecting cord like the one shown in the 
illustration for connection of the amplifier. Use the L-2 (MAIN
