Adjusting the Crossover Settings (X-OVER)
Before performing the following procedures, refer to “About the
Crossover” (page 38).
2.2ch (3WAY) System
1 After selecting X-OVER from the Sound Field
Adjustment mode, turn the Rotary encoder to
select the band adjustment, and then press
/ENTER.
2.2ch (3WAY) System / NORMAL (L=R)
Setting items:
LOW / MID-L / MID-H / HIGH
2.2ch (3WAY) System / INDIVIDUAL (L/R)
Setting items:
LOW-L / LOW-R / MID-L-L / MID-L-R / MID-H-L /
MID-H-R / HIGH-L / HIGH-R
2 Turn the Rotary encoder to select an item to
adjust, then press
/ENTER.
Cut-off frequency
3 -1 Turn the Rotary encoder to select the desired cut-
off frequency (Crossover Point).
Adjustable frequency bands:
2.2ch (3WAY) System
Setting items:
LOW / MID-L 20 Hz~200 Hz
MID-H 20 Hz~20 kHz
HIGH (1 kHz~20 kHz)*

1
When FACTORY’S is selected, refer to “Setting the Response Slope
for the High Range Speaker (TW Setup)” (page 36).
*
2
When USER’S is selected, refer to “Setting the Response Slope for
the High Range Speaker (TW Setup)” (page 36).
Level Adjustment
3 -2 Turn the Rotary encoder to adjust the output level.
Adjustable output level: –12 to 0 dB.
Slope Adjustment
3 -3 Turn the Rotary encoder to adjust the slope.
Adjustable slope: FLAT*, 6 dB/oct., 12 dB/oct., 18 dB/oct.,
24 dB/oct.
* FLAT can be set for the HIGH slope only when USER’S is selected in
“Setting the Response Slope for the High Range Speaker (TW
Setup)” (page 36). Depending on the response characteristics of the
speaker, care should be taken when setting the response slope to
FLAT, as speaker damage may result. With this unit, a message is
displayed when the response slope for the high range speaker is set
to FLAT.
4 Repeat steps 1 to 3 to make adjustment to the other
bands.
4.2ch (FRONT/REAR/SUBW.) System
1 After selecting X-OVER from the Sound Field
Adjustment mode, turn the Rotary encoder to
select the band adjustment, and then press
/ENTER.
4.2ch (FRONT/REAR/SUBW.) System / NORMAL (L=R)
Setting items:
LOW (SUB-W) / MID (REAR) / HIGH (FRONT)
4.2ch (FRONT/REAR/SUBW.) System / INDIVIDUAL (L/R)
Setting items:
LOW (SUB-W)-L / LOW (SUB-W)-R / MID (REAR)-L /
MID (REAR)-R / HIGH (FRONT)-L / HIGH (FRONT)-R
2 Turn the Rotary encoder to select an item to
adjust, then press
/ENTER.
Cut-off frequency
3 -1 Turn the Rotary encoder to select the desired cut-
off
frequency (Crossover Point).
Adjustable frequency bands:
4.2ch (FRONT/REAR/SUBW.) System
Setting items:
20 Hz~200 Hz
Level Adjustment
3 -2 Turn the Rotary encoder to adjust the output level.
Adjustable output level: -12 to 0 dB.
Slope Adjustment
3 -3 Turn the Rotary encoder to adjust the slope.
Adjustable slope: FLAT, 6 dB/oct., 12 dB/oct., 18 dB/oct.,
24 dB/oct.
4 Repeat steps 1 to 3 to make adjustment to the other
bands.
• While adjusting the X-over, you should consider the frequency
response of the connected speakers.
• About the 2.2ch (3WAY)/4.2ch (FRONT/REAR/SUBW.) system
You can switch to 2.2ch (3WAY)/4.2ch (FRONT/REAR/SUBW.)
system mode with the 2.2ch (3WAY)/4.2ch (FRONT/REAR/SUBW.)
switch on the PXA-H100. For details, refer to the Owner’s Manual of
PXA-H100.
