Earthquake products are capable of generating high sound pressure
levels. You
should exercise caution when operating these products. Long term exposures to
high levels of sound pressure will cause permanent damage to your hearing.
Sound pressure levels exceeding 85dB can be dangerous with constant exposure. Set your audio
system to a comfortable loudness level. Earthquake Sound Corporation does not assume liability
for damages resulting from the direct use of Earthquake amplifiers or other Earthquake products ,
and urges users to play their music at moderate listening levels.

Care and Maintenance
Your Earthquake Stereo 7-Band Graphic Equalizer is an example of superior design and
craftsmanship. The following advisories will help you care for your equalizer so you can
enjoy it for years to come.
Keep the graphic equalizer dry. If it gets wet, wipe it dry immediately.
Liquids contain minerals that can corrode electronic circuits. Additionally
liquids can cause severe electrical shock.
Use and store the graphic equalizer only in normal temperature
environments. Temperature extremes can shorten the life of electronic
devices and warp or melt plastic parts.
Handle the graphic equalizer 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.
Keep the graphic equalizer away from dust and dirt, which can cause
premature wear of parts.

Input Gain setting:
Designed to set the maximum upper volume level, the Input Gain is a tool for installer to protect the system from excessive
high volume. Setting the Input Gain level depends on the sources' maximum signal strength (expressed in V
oltage). Installer
needs to know the output voltage of the source units and set the Input gain accordingly
.
