YVC-1000 White Paper

YVC-1000 sets an appropriate delay in sound from the built-in speakers in accordance with the measurement results
to correct the differences in delay between the external and built-in speakers. This setting value is retained even if
the power is turned off.
4) Correction for the frequency response of external speaker(s)
If the frequency responses are greatly different between the external and built-in speakers, the localization of
sounds simultaneously reproduced from the external and built-in speakers will be scattered. For example, it is
conceivable that there are situations that would be illusory whereas it would seem that the mid-low range sounds
are being emitted from the external speakers, and that the high range sounds are being emitted from the internal
speakers. As a countermeasure for this type of phenomenon, YVC-1000 adaptively corrects the frequency properties
in regard to the signals being sent to the external speakers, thus it can cause the frequency properties of the
external speakers to get near to the frequency properties of the internal speakers. The frequency response
characteristics of the external and built-in speakers are measured by executing the automatic audio tuning function
and reproducing the measuring sounds. This setting value is retained even if the power is turned off.
