1 Enhancing the Acoustic Realism of the Sound (iAFC) CVP-509 CVP-505 CVP-503 CVP-501 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. 1 Call up the operation display. CAUTION When using iAFC, do not block or cover the speaker located on the rear panel of the instrument. The optimal iAFC effect cannot be obtained if this speaker is blocked. NOTE 1 [FUNCTION] → [H] iAFC SETTING 2 Press the [D] button to turn the iAFC on. iAFC uses Yamaha's EMR (Electronic Microphone Rotator) technology to ensure stability against acoustic feedback. Perform the piano songs by Clavinova 3 3 Use the [3 ▲▼] - [6 ▲▼] buttons to adjust the iAFC effect depth. [3 ▲▼]/ DYNAMIC [4 ▲▼] DAMPER EFFECT [5 ▲▼]/ SPATIAL [6 ▲▼] 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 instrument is processed to create a spacious sensation. Spatial Effect creates a sense of reverberation and spaciousness by picking up the output sound using internal microphones and output the sound from the speaker on the rear of the instrument. The spread and spaciousness of the sound is different depending on the depth. The default setting for the depth is 0. For lower depth settings: This creates the resonance and enhances the acoustic realism of the sound that is characteristic of acoustic instruments by creating a virtual soundboard. For deeper depth settings: The sound of the instrument itself and the sound of singing and other instruments played nearby is picked up by internal microphones, and processed to simulate the spatial characteristics of performing together on stage. 34 CVP-509/505/503/501 Owner's Manual
