Using, Creating and Editing Voices Enhancing the Acoustic Realism of the Sound (iAFC) iAFC cannot be used in the following cases. • When the Speaker setting is Headphones SW (page 17), and headphones are connected. • 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 (Electronic Microphone Rotator) technology to ensure stability against acoustic feedback. 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 reverberation 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. 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. Adjusting the iAFC Depth The depth of the acoustic piano resonance simulation and stage ambience simulation can be set. 1 Call up the operation display.
