Enhancing the Acoustic Realism of the Sound (iAFC)
When iAFC is engaged, the instrument will sound deeper and more resonant, similar
to an acoustic musical instrument. This lets you experience the ambience and rever-
beration that are characteristic of performing on stage or simulates the sustain sound
that occur when you press the damper pedal of a grand piano.
This section describes how to make various settings for the iAFC function. You can
also perform an automatic adjustment in order to obtain the optimal iAFC effect.

Adjusting the iAFC Depth

The depth of the acoustic piano resonance simulation and stage ambience simula-
tion can be set.

• DYNAMIC DAMPER Effect
This simulates the sustain sound that occurs when you press the damper
pedal of a grand piano. The microphone is not used, but the sound pro-
duced within the instrument is processed to create a spacious sensation.
iAFC cannot be used in the
following cases.
•When the Speaker setting is
Headphones SW (page 17),
and headphones are con-
nected.
•When the Speaker setting is
Off.
•(CVP-409 grand piano type)
When the lid is closed or open
with the shorter stay.
When using iAFC, do not block
or cover the speaker located on
the underside of the keyboard
(CVP-409 grand piano type) or
the rear panel (CVP-409/407) of
the instrument. The optimal iAFC
effect cannot be obtained if this
speaker is blocked.
iAFC uses Yamaha’s EMR (Elec-
tronic Microphone Rotator) tech
-
nology to ensure stability against
acoustic feedback.
Turning on the iAFC of the CVP-409 grand piano type
To turn on the iAFC, open the lid with the longer stay using the inner recess.
When the lid is closed or open with the shorter stay, the iAFC will not be
turned on.
