– 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 250.
– 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.
– 4 – Differential inputs only amplify the difference between two con- ductors. Note: the noise spikes appear on both the center conduc- tor and the outer shield and therefore are not amplified. Center Conductor Outer Shield RCA Input Differential Input Figure 2 ◆ Balanced Line Inputs (250.
250. 2 D ESIGN F EA TURES 1. Cast Aluminum Heatsink – The cast aluminum heatsink of the Punch Power amplifier dissipates heat generated by the amplifier's circuitry. The inherent advantage of casting provides a 30% improvement of cooling over conventional extrusion heatsink designs.
10. Input Sensitivity Controls – The input level controls are preset to match the output of most source units. They can be adjusted to match output levels from a variety of source units. 11. Internal Crossovers – These built-in crossover cards are configurable for a multitude of operating frequencies.

10. Internal Crossover – This built-in crossover card is configurable for a multitude of operating frequencies. The orientation of the card in its socket determines the function of high-pass, low-pass or full range operation. 11. Phase Switch – This switch enables you to easily invert the phase without having to disconnect the speaker wires.

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.
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.
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.
