How to Interpret the Graphs (Continued)
Reading the group delay characteristics graph (Group Delay)
Group delay characteristics graphs for before and after calibration can be displayed. By comparing the two,
it is possible to check in detail the group delay characteristics of the speakers being used and the effect of
calibration using the Full Band Phase Control function.
Group delay characteristics graph for before calibration
This graph lets you check that the low frequency band is delayed with respect to the high frequency band
(that a group delay is occurring) for the different channels.
Group delay characteristics graph for after calibration
This graphs shows you that the delay time difference between bands has been reduced and that the group
delay has been calibrated for the different channels.
Depending on the speakers being used, the listening environment, etc., the group delay characteristics
graphs may be displayed with sharp angles. With actual calibration, however, so as not to tarnish the natural
sound, compensation is not performed for characteristics that rise and fall at extremely sharp angles and
but instead with priority on group delay characteristics between the different speakers, so there is no
adverse effect on the sound quality.
