Enhancing The Acoustic Realism Of The Sound (Iafc); Selecting The Iafc Type And Adjusting The Depth - Yamaha CVP-309PE Owner's Manual

Enhancing the Acoustic Realism of the Sound (iAFC)

iAFC cannot be used in the
following cases.
• (CVP-309 grand piano type)
When the lid is closed or open
with the shorter stay.
• When the Speaker setting is
Headphones SW (page 17),
and headphones are con-
nected.
• When the Speaker setting is
Off.
When using iAFC, do not block
or cover the speaker located on
the underside of the keyboard
(CVP-309 grand piano type) or
the rear panel (CVP-309/307) of
the Clavinova. 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.

Enhancing the Acoustic Realism of
the Sound (iAFC)
When iAFC is engaged (the default setting is ON), the Clavinova will sound deeper
and more resonant, similar to an acoustic musical instrument. Sounds picked up by
a microphone and sounds produced internally by the Clavinova are processed and
output from the rear speaker to enhance the acoustic realism of the sound. The iAFC
processing is most effective with the grand piano Voice (the one selected by pressing
the PIANO button).
Turning on the iAFC of the CVP-309 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.
Selecting the iAFC Type and Adjusting the
Depth
This section describes how to adjust various iAFC settings, such as selecting the
iAFC type and adjusting the depth.
There are three iAFC types as shown below. Select the desired type: stage ambi-
ence simulation or acoustic piano resonance simulation. Each type consists of
three sub-types. The depth can also be set for each type.

• 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 Clavinova is processed to create a spacious sensation.
