Pedal Connector
You can connect the optionally available 3-Pedal Unit 
(SP-33) to the pedal connector on the bottom of the 
Digital Piano. You can then use the pedals for 
expression that is similar to that available on an 
acoustic piano.
NOTE
• The SP-33 Pedal Unit supports half-pedal operation 
(pressing the pedal part way). You can adjust the 
amount of the effect is applied when the damper 
pedal is pressed part way. For details, see “Half 
Pedal Effect” (page E-46).
• The optionally available CS-67P special stand is 
required in order to use the SP-33 Pedal Unit.
You can connect audio equipment or a music amplifier 
to the Digital Piano and then play through external 
speakers for more powerful volume and better sound 
quality.
IMPORTANT!
• The Digital Piano automatically adjusts sound output 
to optimize for headphone output (when headphones 
are connected) or built-in speaker output (when 
headphones are not connected). This also will cause 
a change in the output quality from the Digital 
Piano’s LINE OUT R and L/MONO jacks.
• Whenever connecting a device to the Digital Piano, 
first use the VOLUME controller to set the volume to 
a low level. After connecting, you can adjust the 
volume to the level you want.
• Whenever you connect any device to the Digital 
Piano, be sure to read the user documentation that 
comes with the device.
