Adjusting the Para-Bass Controls
Setting The Bass Output Control
The bass response in a system is affected by four factors:
(1) The acoustics of the vehicle
(2) The locations of the speakers
(3) The music on the tape
(4) Speakers and speaker enclosures.
Because of the variations in the recording process, we developed OptiX-9 to help
restore any low frequencies lost during the recording process, however, the acoustics
of various environments are different.
The Sweep control allows you to select a center frequency (the frequency most
affected) between 27 and 63 Hz. The Width control then allows you to control the shape
of the filter centered around the Sweep frequency.
The Optix-9 is the most powerful bass component. This device equipped with several
different Bass Output selections. If you should need to change the settings, Please use
the chart below for guidance. It is recommended
：listen to the factory setting before
changing your Bass Output settings.
