– 1 – Rockford Fosgate is distinguished as the global leader in building high performance amplifiers. Since the introduction of the 250m 2 and 250m, new performance standards were set for sound quality and flexibility and have risen to an even higher level with the introduction of the 50.2 and 50.1 “competition” amplifiers. The “50 series[...]

– 2 – T ECHNICAL D ESIGN F EA TURES Many of the solutions to common design problems encountered by Rockford Fosgate engineers created entire new circuit designs as well as new ways to construct the Punch 50. 2 and 50. 1 Power Amplifiers. In our flagship amplifiers, no expense was spared in design and construction from the unique circuitry desig[...]

– 3 – ◆ DSM (Discrete Surface Mount Technology) The DSM ( D iscrete S urface M ount) manufacturing process combines the advantages of both discrete components and integrated circuitry. Rockford Fosgate is the only American amplifier manufacturer to have invested millions into this process. DSM components differ from conventional discrete comp[...]

– 4 – Differential inputs only amplify the difference between two conductors. Note: the noise spikes appear on both the center conductor and the outer shield and therefore are not amplified.

M OUNTING L OCA TION S The mounting location and position of your amplifier will have a great effect on its ability to dissipate the heat generated under normal operation. The design of our cast aluminum heatsink serves to easily dissipate the heat generated over a wide range of operating conditions. However, to maximize the performance of your amp[...]

W IRING T HE S YSTEM CAUTION: Avoid running power wires near the low level input cables, antenna, power leads, sensitive equipment or harnesses. The power wires carry substantial current and could induce noise into the audio system. 1. Configure the internal XCard crossovers prior to installation. Refer to the “Using the Signal Switching Network?[...]

U SING P ASSIVE C ROSSOVERS A passive crossover is a circuit that uses capacitors and/or coils and is placed on speaker leads between the amplifier and speaker. The crossover delegates a specific range of frequencies to the speaker for optimum driver performance. A crossover network can perform one of three functions: High-Pass (capacitors), Low-Pa[...]
