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.Setting (Pedal 
Setting)” (page E-96).
You can connect a dynamic microphone (only) to the Digital 
Keyboard for output thorough the Digital Keyboard’s 
speakers.
• You can adjust the volume level of microphone input with 
the T-6 (MIC VOLUME) knob. Microphone volume control 
is independent of overall keyboard volume.
• Built-in effects (reverb, chorus, DSP) are also applied to 
input from the microphone. You also can use the Mixer to 
adjust how effects are applied, the speaker stereo pan 
position, and other parameters.
For details, see “Selecting and Playing a Tone” (page E-13) 
and “Using the Mixer” (page E-38).
• Before connecting a microphone, make sure that the 
Digital Keyboard and microphone are turned off.
• Before connecting a microphone, set both the L-2 
(VOLUME) and T-6 (MIC VOLUME) knobs to low levels. 
Adjust volume settings to appropriate levels after 
connecting the microphone.
