Automatic Adjustments

Preparations for automatic adjustments

The PXI-H990 is equipped with two automatic adjustment functions: “Road Equalizer” and “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 (Using the Road Equalizer function)” (page 15) and “Performing time correction automatically (Automated Time Correction)” (page 21) to perform the respective automatic adjustments.

• When performing automatic adjustment, set the head unit to the TUNER mode before adjusting.

1 Check that the head unit defeat mode is off.

2 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 7.) 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 42, “Crossover adjustment/Switching the phase”, for more information on setting the crossovers.
