If you select the “SPATIAL EFFECT”, make sure to execute the calibration
operation (page 83).
•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 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 per-
forming 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.”
1Press the [I] (MIC CALIBRATION) button in the iAFC operation display
(page 82) to call up the calibration display.
2Press 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.
