6 Touch [] of X-OVER.

The X-OVER adjustment screen appears.

7 Touch a desired adjustment mode.

FREQ: Adjust the H.P.F. or L.P.F. cutoff frequency. The adjustable bands differ according to the channel (speaker).

SLOPE: Adjust the H.P.F. or L.P.F. slope.

LEVEL: Adjust the H.P.F. or L.P.F. level.

8 Touch [;] or [:] of the speaker to adjust its channel.

9 When adjusting another channel, repeat steps 7 and 8 above.

10 Touch [RETURN] to return to the previous screen.

When the speaker is set to the “OFF” mode, the X-OVER for that speaker cannot be set. Refer to “Setting the Speakers” (page 44).

Check the playback frequencies of the connected speakers before adjusting.

In order to protect the speakers, there is no OFF setting for the subwoofer low pass filter (the slope remains the same).

Even if Tweeter is selected for FRONT 1, the filter OFF (slope OFF) of the H.P.F. can be set. If the slope is set to OFF, speakers may be damaged. Take care with this setting.

Performing Time Correction Manually (TCR)

Because of the particular conditions inside the vehicle, there can be major differences in the distances between the various speakers and the listening position. It is possible to calculate the optimum correction values and eliminate the time error at the listening position yourself using this function.

1 Check that Defeat mode is off.

2 Sit in the listening position (the driver’s seat, for example) and measure the distance (in meters) between your head and the various speakers.

3 Calculate the difference in distance between the farthest speaker and the other speakers.

L = (distance of farthest speaker)

– (distance of other speakers)

4 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.

Conditions:

Distance between farthest speaker and listening position: 2.25 m (88-3/4")

Distance between front left speaker and listening position:

0.5m (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)

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.
