Description: Rockford steps it up this year with their redesigned Power Series amplifiers. Power series amplifiers begin where the Punch series leaves off. All multi channel Power series amps come with rear Punch Bass, a remote operated bass level control that helps correct for missing low bass output in the automotive sound environment without adding excessive boost. The supplied remote level knob can be installed anywhere for easy tuning. The Power 551X features a built-in 24 dB slope high/low pass front/rear crossover continuously variable from 50-250 Hz. Rockford?s TRANS?ana (TRANSconductance Active Nodal Amplifier) MOSFET circuitry simplifies the current and voltage gain while TOPAZ (Tracking Operation Pre Amplifier Zone) circuitry eliminates 80% of unwanted noise created by ground loops. Power series amplifiers feature discreet surface mount technology (DSM) utilizing high-speed robotics to produce circuit boards that are more efficient, put out more power, and are less prone to unwanted noise. To keep the amp protected, Rockford?s NOMAD (NOn-Multiplying Advanced Decision) protection circuitry uses an analog computer that serves to protect, but not limit the amp. How does the Power amp deliver such a wallop of energy to your music? The answer lies in Rockford?s INDIGO (INDexed Ideal Gain Operation) power supply, which lets the amplifier operate with more flexibility than tightly regulated power supplies. The result is sound so clean and bass so tight you have to hear it to believe it. Minimize
