Introduction
To adjust the volume of the entire keyboard sound, use
the [MASTER VOLUME] while playing the key-
board.
Intelligent Acoustic Control (IAC)
With this function, the sound quality of this instru-
ment is automatically adjusted and controlled accord-
ing to the overall volume. Even when the volume is
low, you can hear both low sounds and high sounds
clearly. IAC Control is effective only from the sound
output of the instrument speakers.
IAC On/Off
Default setting: on
IAC Depth
Setting range: -3 – 0 – +3
Default setting: 0
When a setup is changed using a button and key com-
bination, an operation sound (“On,” “Off,” click,
tempo value input) is sounded. This confirmation
sound can be enabled (On) or disabled (Off) as
desired.
Connect a pair of headphones to the [PHONES] jack.
Since this instrument is equipped with two
[PHONES] jacks, you can connect two pairs of head-
phones. If you are using only one pair, insert the plug
into either of these jacks.
Reproducing natural sound distance (Stereo-
phonic Optimizer)
Default setting: on
The Stereophonic Optimizer recreate for headphones
a natural distance between your ears and the instru-
ment, just as when playing an acoustic piano.
Stereophonic Optimizer On/Off
While holding down [PIANO], press the F3 key to
turn the function off or F#3 to turn on.
