Headphones

The piano is equipped with two sets of standard stereo headphone jacks to accommodate
private practice or late-night playing. The internal speaker system is automatically shut off
when a pair of headphones is plugged into the 1. Headphone jack.

MIDI OUT

MIDI (Musical Instrument Digital Interface) is a world-standard communication interface
which allows electronic musical instruments to communicate with each other, by sending
and receiving compatible note, program change and other types of MIDI data. You should
only plug the MIDI out in to another device featuring a MIDI input.

Line OUT

The piano's stereo RCA line output can be used to deliver the output of the piano to a
keyboard amplifier, stereo sound system, mixing console or tape recorder. The piano's
internal sound system will remain on unless headphones are plugged in to the 1.
Headphone jack.
