Rockford engineers designed the Punch 55.2, 75.2, 125.2 and 225.2 amplifiers to withstand the rugged automotive environment while delivering superior sound quality in a flexible, reliable, and efficient package. TRANS•ANA is a low voltage circuit in the preamp stage of all Punch .2 amplifiers that lets the music sound crystal clear and very real, even when played at high volume levels. This is matched with TOPAZ, a unique grounding circuit used to eliminate noise problems associated with car audio systems and their installation. Flexibility is accomplished with the use of a built-in XCard. Reliability is all but guaranteed with the use of a protection circuit called NOMAD, while MOSFET and DSM (Discrete Surface Mount) technology improve amplifier efficiency. The result of these components give the Punch amplifier awesome sound quality in a “Bullet Proof” package. An explana- tion of these technologies, most of which are exclusively designed and patented by Rockford, are described in the Technical Design Features.
