MB1 Digital Bass Synthesizer (Open-Box)

Most factory stereos, even high-end systems, protect speakers by reducing subharmonic output when the volume is high. That’s OK in a regular system, but this bottleneck system will handicap low frequency performance if you want to upgrade your factory stereo with amplifiers and subwoofers.

The Earthquake MB1 detects the input level from a factory stereo and adds more bass at high volume levels while keeping your bass response balanced at low volume. Now, you can keep your factory stereo looking flush and its steering wheel controls intact while improving the bass quality and depth.

The MB1 easily wires up to any system and can be mounted in the front or rear of the vehicle. It has two gold-plated inputs and outputs, plus a remote dash control for easy adjustments. The SWEEP and WIDE controls manage frequency ranges for extremely high-precision custom-built bass response.

PLEASE NOTE: This is an open-box item that has been refurbished and tested. Minor signs of use may be cosmetically visible.

Advanced Bass Maximization:

The MEGA BASS Digital Synthesizer contains a bass maximization circuit that perfectly reproduces and pumps low frequency information back into the voltage line. This means the synthesizer will enhance bass impact when using CDs, Tapes, and even portable media players, such as iPods and MP3 players.

Bass Circuit:

This is how MEGA BASS allows you to control your newfound bass. This cool equalization circuit contours the restored bass to your speaker system.

Easy Access Dash Mount Control Center:

MEGA BASS is designed to be mounted anywhere in your vehicle, with the exception of the obvious things like the bumpers and the gas tank. The MEGA BASS package comes with a dash-mount control center, which allows you to control the intensity of your 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.

DCF D.C. Filter:

The DCF over-drive circuit allows the user to experience massive bass while protecting the speaker from DC failure, which is typical in other bass enhancement devices.

Bass Expander Limiter:

The MEGA BASS circuitry produces huge amounts of hard-hitting, concrete-shattering bass without damaging speakers. The Bass Expander Limiter circuit allows MEGA BASS to enhance the bass output of any audio system while controlling damaging burps.
