Select the Media Xpander mode by sliding your
finger on the GlideTouch bar to the left or right.
Press the GlideTouch bar under the Media
Xpander mode.
9
Select the MX Level by sliding your finger on the
GlideTouch bar to the left or right. Press the
GlideTouch bar under the desired level or OFF
(Non Effect).
FM (MX level 1 to 3):
The medium to high frequencies become clearer, and
produces well balanced sound at all frequencies.
CD (MX level 1 to 3):
CD mode processes a large amount of data during playback.
MX takes advantage of this large data quantity to reproduce a
more clear, clean output.
CMPM (MX level 1 to 3):
This corrects information that was lost at the time of
compression. This reproduces a well-balanced sound close to
the original.
DVD (Video CD)
(MOVIE MX level 1 to 2):
The dialogue portion of a video is reproduced more clearly.
(DVD MUSIC):
A DVD or Video CD contains a large quantity of data such as
music clip. MX uses this data to reproduce the sound
accurately.
AUX (MX level 1):
Choose the MX mode (CMPM, MOVIE, or MUSIC) that
corresponds to the media connected.
If two external devices are connected, a different MX
mode for each media can be selected.

After setting, press and hold MENU for at least 2
seconds to return to normal mode.
The contents of MX set here is reflected to PXA-H700 or PXA-
H701.
When OFF is selected, MX effect of each MX mode will be OFF.
Each music source, such as radio, CD, and MP3 can have its own
MX setting.
MX mode does not function when MX is ON for AM radio.
MX COMPRESS MEDIA is applied for MP3/WMA, MMD and
iPod.
If no operation is performed for 15 seconds, the unit will return to
the normal mode.
X-OVER Adjustment
1
Check that Defeat mode is off (page 20).
2
Press and hold MENU for at least 2 seconds.
3
Select the Crossover (X-OVER) mode by sliding
your finger on the GlideTouch bar to the left or
right. Press the GlideTouch bar under the
Crossover (X-OVER) mode.

Select L+R or L/R by pressing and holding BAND
for at least 2 seconds.
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.
5
Select the desired channel by pressing BAND.
6
Touch the GlideTouch bar, and select the desired
cut-off frequency (Crossover Point) by sliding it to
the left or right, then press the GlideTouch bar.
7

When the setting is complete, press and hold
MENU for at least 2 seconds.
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).
The H.P.F. filter cannot be set to OFF (slope OFF) if Tweeter is
selected for FRONT1. Or, only the subwoofer is adjustable if
STEREO is selected for the subwoofer.
When the setting is complete, it is recommended to store the setting
contents. For storing, refer to page 51.
Performing Time Correction Manually (TCR)/
Phase Switching
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.
Calculating the Time Correction
1
Sit in the listening position (the driver’s seat, for
example) and measure the distance (in meters)
between your head and the various speakers.
2
Calculate the difference in distance between the
farthest speaker and the other speakers.
L = (distance of farthest speaker)
– (distance of other speakers)
3
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:
0.5 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)
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.
