Using, Creating and Editing Voices Enhancing the Acoustic Realism of the Sound (iAFC) 4 Press the [5π†]/[6π†] buttons to adjust the SPATIAL EFFECT depth. If you select the "SPATIAL EFFECT", make sure to execute the calibration operation (see below). • SPATIAL EFFECT 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 underside (CVP-409 grand piano type) or the rear (CVP-409/ 407) 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. Calibrating the iAFC Settings This automatically adjusts the sensitivity and response of iAFC so that the optimal iAFC effect will be obtained. Make sure to execute this operation when you use "SPATIAL EFFECT." 1 Press the [I] (MIC CALIBRATION) button in the iAFC operation display (page 82) to call up the calibration display. 2 Press the [G] (CALIBRATION START) button to begin calibration. When automatic adjust begins, a test sound (noise) will sound for about five seconds. While automatic adjustment is being performed, do not make audible noises in the vicinity of the Clavinova. If the iAFC effect is slight or inaudible: If it seems that iAFC is not effective when playing back Songs or Styles, turn the iAFC feature off. 1 Call up the operation display.
