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 material
(4) Speakers and speaker enclosures.
Because of the variations in the recording process, we developed BX-4EQ 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.
Adjusting the Para-Bass Controls
The BX-4EQ is the most powerful bass component. This device is 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.
