WHY THE MB1 MEGA BASS?

The bass response in a system is affected by four (4) factors:
   1. The acoustics of the vehicle
   2. The location of the speakers
   3. The music being played
   4. The speakers and/or speaker enclosures
Due to the variations in the recording process, the  MB1 is engineered with 
amazing features to help restore any low frequencies lost during the process or 
cause by the source unit, regardless of the different environment acoustics.

A

DVANCED DIGITAL BASS RESTORATION SYSTEM

The  MB1  MEGA  BASS  Digital  Synthesizer  contains  a  bass  maximization 
circuit  that  perfectly  reproduces  and  pumps  low  frequency  back  into  the 
voltage line. Therefore, this synthesizer will enhance bass impact when using 
CDs, tapes and portable media players.

SUBWOOFER MAXIMIZATION CONTROL CIRCUITRY

The MB1’s advanced bass equalization circuit contours the restored bass to 
your speaker system.

EASY ACCESS DASH MOUNT CONTROL CENTER

The  MB1  is  designed  to  be  mounted  anywhere  in  the  vehicle,  with  the 
exception of the obvious places like the bumpers and gas tank. Each  MB1 
comes  with  a  dash  mount  control  center  which  allows  you  to  control  the 
intensity of the system’s bass output right from the driver’s seat. In addition, the 
dash mount unit comes with a built-in dual LED that dims and brightens as the 
bass increases and decreases.

DPF (DC PROTECTION FILTER)

The  MB1’s  DPF  overdrive  circuitry  allows  the  user  to  have  massive,  hard 
hitting,  concrete  shattering  bass  while  protecting  the  speakers  from  DC 
failures, commonly found in other bass enhancement devices.  

BASS EXPANDER LIMITER

The  MB1’s  Bass  Expander  Limited  circuitry  allows  it  to  enhance  the  bass 
output of any audio system while controlling damaging burps.

CARE AND MAINTENANCE

Your Earthquake MB1 bass synthesizer is an example of superior design and 
craftsmanship.  The  following  advisories  will  help  you  care  for  your  bass 
synthesizer so you can enjoy it for years to come:

Keep  the  bass  synthesizer  dry.  If  it  gets  wet,  wipe  it  dry 
immediately. Liquids contain minerals that can corrode electronic 
circuits. Additionally, liquids can cause severe electrical shock.

Handle the bass synthesizer gently and carefully. Dropping it can 
damage the circuits or cause components to break or become 
loose. These kind of actions can cause the units to work poorly or 
improperly.

Use and store the bass synthesizer only in normal temperature 
environments.  Temperature  extremes  can  shorten  the  life  of 
electronic devices and warp or melt plastic parts. 

Keep the bass synthesizer away from dust and dirt, which can 
cause premature wear of parts.
