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.
