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 connected. • 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. 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 iAFC uses Yamaha's EMR (Electronic Microphone Rotator) technology to ensure stability against acoustic feedback. 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 ambience simulation or acoustic piano resonance simulation. Each type consists of three sub-types. The depth can also be set for each type. 1 Press the [iAFC SETTING] button to call up the operation display.

If you select the "NATURAL SOUND BOARD" or "SPATIAL ENSEMBLE," make sure to execute the calibration operation (page 77). • 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 produced within the Clavinova is processed to create a spacious sensation. 76 CVP-309/307 Owner's Manual
