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.
Connecting to Audio Equipment 1
Use commercially available cables to connect the 
external audio equipment to the piano’s 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 cables 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 piano is 
connected. Use the piano’s VOLUME controller to 
adjust the volume level.
Connecting to a Musical Instrument 
Amplifier 2
Use commercially available cables to connect the 
amplifier to the piano’s 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 connecting cable like the one 
shown in the illustration for connection of the 
amplifier. Use the piano’s VOLUME controller to 
adjust the volume level.
IMPORTANT!
• When using the LINE OUT jacks, also connect 
headphones to the PHONES jacks. This will switch 
the LINE OUT output to appropriate sound quality.
Use only accessories that are specified for use with this 
Digital Piano.
Use of unauthorized accessories creates the risk of fire, 
electric shock, and personal injury.
