The Audio Transient Suppressor is designed to eliminate the potential damaging turn on and turn off transient pop that you get when turning on and off your mixer. Most audio engineers know to turn on your mixer first and then power up the power amplifiers in the system and to reverse the order when powering down the system. The problem is that many times systems are damaged by the large turn on and turn off transients due to an untrained operator, power failures, accidental removal of the power (someone tripping on the power cord) or any number of other reasons. The end result can be blown speakers and or power amplifiers.
