Divide the distances calculated for the different
speakers by the speed of sound (343 m/s
temperature 20°C).
This value is the time correction value for the various
speakers.
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.

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: Different adjustment values can be set for the left and
right channels.
L+R: Sets the same adjustment values 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.
