Concrete examples
Calculating the time correction value for the front left speaker on
the diagram below.
In other words, setting the time correction value for the front left
speaker to 5.1 (ms) sets a virtual distance matching the
distance to the farthest speaker.
4
Touch
[
]
or
[
]
of Time Correction.
Select L+R or L/R.
5
Touch the title bar of Time Correction.
The Time Correction adjustment screen appears.
6
Adjust the time correction value (0.00 ~ 20.00ms) of a
desired speaker by touching the respective
[
]
or
[
]
button (1 step = 0.05ms).
•
When the speaker is set to the “OFF” mode, the TCR for that
speaker cannot be set. Refer to “Setting the Speakers” (page 81).
•
The adjustment value for Front2 (Speakers) which is adjusted in time
correction, is also applied to the front speakers in “Setting Bass
Focus” (page 78).
•
The adjustment (AUTO TCR) cannot be automatically set on this
unit.
Setting item: Phase
Switch the phase (0° or 180°) by touching
[
]
or
[

of
the desired speaker.
The graphic equalizer allows you to modify the sound using 31 bands
each for the front (left and right), rear (left and right) and center
speakers. An additional 10 bands are available for the subwoofer. This
allows you to customize the sound to suit your taste.
Setting item: G-EQ
1
Select L+R or L/R by touching
[
]
or
[
]
of G-EQ.
When parametric EQ is adjusted, this setting will be turned
off.
2

The G-EQ list screen appears.
3
Touch the title bar of the desired speaker (channel).
The G-EQ adjustment screen appears.
4

When Graphic EQ is adjusted, this setting will be turned off.
Conditions:
Distance between farthest speaker and listening position:
2.25 m (88-3/4")
Distance between front left speaker and listening position:
0.5 m (20")
Calculation:
L = 2.25 m (88-3/4") – 0.5 m (20")= 1.75 m (68-3/4")
Compensation time = 1.75 ÷ 343 x 1000 = 5.1 (ms)
L+R:
Sets the same adjustment values for the left and right
channels.
L/R:
Different adjustment values can be set for the left and
right channels.
2.25m
0.5m
5.1ms
The sound is uneven because
the distance between the
listening position and the
different speakers is different.
The difference in the distance
between the front left and rear
right speakers is 1.75 meters
(68-3/4").
Time correction eliminates
the difference between the
time required for the sound
from the different speakers to
reach the listening position.
Setting the time correction of
the front left speaker to 5.1
ms makes it possible to
coordinate the distance from
the listening position to the
speaker.
