Rockford engineers designed the Punch 2-channel 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 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 crossover. The use of a protection
circuit called NOMAD, along with MOSFET and DSM (Discrete Surface
Mount) technologies improve amplifier efficiency. The result of these
components give the Punch amplifier awesome sound quality in a “Bullet
Proof” package. An explanation of these technologies, most of which are
exclusively designed and patented by Rockford, are described in the
Technical Design Features.
