HDBR FEATURES

Bass Driver: The HDBR contains a Bass Driver circuit that accurately recreates and injects

Low Frequency information back into the signal path. What that means in everyday terms is
that the HDBR will give more bass impact to your best compact discs or lowest quality
recordings.

Bass Equalization Circuit: The HDBR has a unique equalization circuit that contours the
restored bass to your speaker systems.

Dash Mount Remote Control: The HDBR comes with a Dash Mountable Remote Control
that allows you to enjoy the effects of the HDBR without having to leave the drivers seat. The
Dash mount Control has an LED indicator that will grow brighter as you add more bass or
dimmer when you decrease it.

Bass Maxximizer Indicator: Not only does the HDBR provide good music to your ears, but
it also gives you some visual enjoyment as well. On the chassis of the HDBR there are three
LED indicators that flash when the bass maxximization circuit is activated.

Bass Output Control: The HDBR has the ability to produce large amounts of deep, ear
blowing bass without damaging your speakers. The Bass Output Control circuit allow the
HDBR to maxximize the bass output of any autosound audio system while restraining
destructive bursts.
