Product Highlights: 

Thank you for considering the EQ10 MP3 Player with USB, SD, Aux input 4-Band Parametric Equalizer from Gravity.  This unit will provide you with years of performance and reliability and here's the highlight.

The EQ10 is intended for those who value the acoustic benefits of a multi-band parametric  equalizer coupled with the power of controlling four amplifier channels and two independent sub woofer channels directly from the car dash board.

This is a passive pre-amp equalizer requiring external amplifier to power the speakers.  It provides 2 channels of front output, 2 channels of rear output and 2 channels of sub woofer output.

Let's talk a little about parametric graphic equalization.

Every car interior produces at least one sharp peak or dip in the frequency response that results in highly unnatural sound reduction.  But the exact frequency and its level of intensity depend on unpredictable factors such as the size and volume of the interior, type of material used for the interior (cloth, leather, vinyl), whether a window is open or how many passengers are inside the car.

Because of these variables, even a multi-band graphic equalizer will not be able to control a particular frequency without unnecessarily affecting others.  The listener is therefore faced with either unwanted alterations of frequencies or having unnatural peaks and dips, which might result in boomy bass, muddied vocal range or harsh treble response.

The purpose of the 4 parametric frequency bands built into this unit is to allow you to tune the basic frequencies in order to correct the problems in the car responses.  Once brought into focus, the problem frequency can then be attenuated or boosted.  Precise control is therefore possible over the entire frequency range.

When increasing the boost of any frequency you are actually increasing the output voltage of the equalizer to the amplifier.  Please be sure that your amplifier has enough "head room" and is capable of handling the source increase without clipping.  It is also important that your speakers are capable of reproducing the frequency range which you have chosen to boost without being over driven.  For example, do not attempt to boost a 60Hz signal to a small midrange driver, this will only cause the midrange to burn out.  The proper procedure for a successful installation is to incorporate either an electronic crossover or a passive crossovers to help control which frequencies will actually reach the proper speakers like these units right here.

Which either of these, combine with the EQ10, you will have full control over the frequency response that push out to your speakers.
