Turn the Rotary encoder to adjust the output level.
Adjustable output level: -12 to 0 dB.

Repeat steps 3 to 6 to make adjustment to the other
bands.
• While adjusting the X-over, you should consider the frequency
response of the connected speakers.
• The stored contents are not deleted even when resetting the unit or
disconnecting the battery.
• The stored contents can be recalled by performing operation in
"Recalling the Stored Crossover Settings" (page 16).
• Pressing
/RTN when X-over is adjusted will return to the previous
item.
• If MultEQ is turned on, the A.SEL button is ineffective. For details,
refer to "Turning MultEQ on/off" (page 12).

About Time Correction
The distance between the listener and the speakers in a car vary widely
due to the complex speaker placement. This difference in the distances
from the speakers to the listener creates a shift in the sounds image and
frequency characteristics. This is caused by the time delay between the
sound reaching the listener's right versus the left ear.
To correct this, this unit is able to delay the audio signal to the speakers
closest to the listener. This effectively creates a perception of increased
distance for those speakers. The listener can be placed at an equal
distance between the left and right speakers for optimum staging.
The adjustment will be made for each speaker in 3.4 cm steps.

Example 1. Listening Position: Front Left Seat
Adjust the time correction level of the front left speaker to a high
value and the rear right to zero or a low value.
0.5m
2.25m
The sound is not balanced because the distance between the
listening position and the various speakers is different.
The difference in distance between the front left speaker and the rear
right speaker is 1.75 m (68-7/8").
Here we calculate the time correction value for the front left speaker
in the diagram on the above.
Conditions:
Farthest Speaker – listening position : 2.25 m (88-9/16")
Front left speaker – listening position : 0.5 m (19-11/16")
Calculation: L = 2.25 m – 0.5 m = 1.75 m (68-7/8")
Time correction = 1.75 ÷ 343
* Speed of sound: 343 m/s (765 mph) at 20°C
In other words, giving the front left speaker a time correction value of
5.1 ms makes it seem as if its distance from the listener is the same
as the distance to the farthest speaker.
Time correction eliminates the differences in the time required for the
sound to reach the listening position.
The time of the front left speaker is corrected by 5.1 ms so that its
sound reaches the listening position at the same time as the sound of
other speakers.
Example 2. Listening Position: All Seats
Adjust the time correction level of each speaker to almost the same
level.
1
Sit in the listening position (driver's seat, etc.) and
measure the distance (in meters) between your head
and the various speakers.
2
Calculate the difference between the distance to the
farthest speaker and the other speakers.
L = (distance to farthest speaker) – (distance to other
speakers)
3
Divide the distances calculated for the speakers by
the speed of sound (343 m/s (765 mph) at 20°C).
These values are the time correction values for the different
speakers.
