Auto HummBuster technology (patent pending) is a state of the art troubleshooting
system invented in the research labs of Roemtech outside of Dallas, Texas. Until now,
when there was an unwanted hum or buzz in an audio system, it required a technician to
come in and analyze the sound system. Typically, this required a modification of the
existing setup, sometimes leading to many more hours of work and untold expenses.
This sort of scenario is not uncommon. With Roemtech's new Auto HummBuster
technology, unwanted noise issues can be resolved with the simple push of a button.
When the Auto HummBuster button is pushed, the PMA-350H's internal circuitry
intelligently analyzes each incoming audio signal. It next determines which audio
source is guilty of generating the noise, then it safely and properly gets rid of it. Due to
sophisticated and proprietary circuitry pioneered by Roemtech, it does all of this while
leaving the original audio content pure and unaffected. The HummBuster feature
should be operated during a time when the source material has been muted or is not
being played but the sources have all been plugged in. It can then make a decision that
