Repeat the settings as explained above.

At this point, the first custom setup can be prepared.
The following is only the description of setup procedure.
The detailed specifications of each parameter are shown in the respective paragraphs of the manual.

Note: The regulation of the MAXIDRIVE3.4's parameters is closely related to the characteristics of the com-

ponents of the sound system. So if you're not the expert, please refer to the documentation and technical
specifications of your power amplifiers, loudspeaker enclosures, monitors, etc.. This will enable you to
work faster and safely.

Note: In this first phase of setting up your sound system, the adjustment of these functions (which if not Indis

-pensable during installation) can wait. But do remember that adjusting the equalizers can also affect the
signal level. So if considerable equalization changes are made, remember to check and adjust the output
levels too, if necessary.
