Automatic Adjustments

Preparations for automatic

adjustments

The PXA-H900 is equipped with two automatic adjustment

functions: “Adaptive Equalizer” and “Precision Automated Time

Correction”.

The preparations described below must be made in order to

perform these automatic adjustments. After making these

preparations, refer to “Automatic adjustments (Adaptive

Equalizer)” (page 16) and “Performing time correction automati-

cally (Precision Automated Time Correction)” (page 20) to

perform the respective automatic adjustments.

Check that the defeat mode is off.

(See page 53.)

Adjust the head unit and amplifier levels.

Head unit:

Set the balance and fader to “center”.

Front, rear and center amplifiers:

Set the amp gains to “center” or “normal” to start.

If there are no rear speakers, check that the rear

speakers are turned off. (See page 8.) Gain

levels may be changed if you are not satisfied

with the automatic results. Make the gain

changes and return the automatic adjustment.

Subwoofer amplifier:

Set the amplifier gain to “center” or “normal”. If

the subwoofer is located in the trunk or a remote

place (for example at the very back of a station

wagon), adjust the subwoofer to increase the

volume several steps.

Speaker Crossovers:

Set the crossovers for all the speakers in the

system that will require them. See page 32,

“Crossover adjustment”, for more information on

setting the crossovers.

Connect the included microphone to the PXA-

H900.

Refer to the Installation manual.

• The adjustment differs according

to the position of the micro-

phone. Search for the position at

which the desired sound quality

can be achieved.

• We recommend using speaker

boxes or box locations that

produce low levels of indirect

sound (for example, sealed boxes

or vented boxes with the vents

firing into the trunk).

• The proper adjustments cannot

be achieved if the subwoofer is

located in the trunk and the trunk

and cabin are separated by a

metal sheet. Either move the

subwoofer into the cabin or open

a hole in the rear tray to join the

two spaces. (This is not

necessary if the partition is not a

metal sheet.)

If the partition is a metal sheet,

open a hole in the rear tray.

If you encounter a problem,

consult your authorized dealer.

Is the partition a metal

sheet?

Or move the subwoofer into the

cabin.

• Do not disconnect the micro-

phone during the automatic

adjustment procedure.
