  • Page 4: Introduction

    N T R O D U C T I O N Rockford engineers designed the Punch 40x 200x 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 x and very real, even when played at high volume levels.
  • Page 5: Technical Design Features

    ECHNICAL TRANS•ANA (TRANSconductance Active Nodal Amplifier) The TRANS•ANA (TRANSconductance Active Nodal Amplifier) is a circuit that allows the audio signal to pass through the amplifier at low voltage. The signal is directly level-shifted to the fixed high voltage rails via a pair of driver transistors. Signal linearity is assured by an active node formed by the drive transistors at ultrasonic frequencies.
  • Page 6 The DSM (Discrete Surface Mount) 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 components in different ways. They are more compact, more rugged, and they efficiently dissipate generated heat.
  • Page 7: Mosfet Devices

    MOSFET Devices Rockford Fosgate is one of the few manufacturers in the sound community to utilize MOSFET devices in both the power supply and the output stages . MOSFET (Metal Oxide Semiconductor Field Effect Transistor) devices offer several important inherent advantages over the 30 year old technology of bi-polar design.

    ESIGN EATURES 1. Cast Aluminum Heatsink – The cast aluminum heatsink of the Punch 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. 2. End Caps – Interchangeable end caps conceal the wiring and input cables, giving the amplifier a clean “stealth”...
  • Page 9 7. Input Sensitivity Controls – The input level controls are preset for 500mV which will match the output of most source units. They can be adjusted to match input levels ranging from 150mV to 3V. 8. Punch Equalization Controls – The Punch EQ helps correct for acoustical deficiencies of the listening environment.

  • Page 11: Mounting Location

    Engine Compartment Mounting Rockford Fosgate amplifiers should never be mounted in the engine compartment. Not only will this void your warranty but could create an embarrassing situation caused by the ridicule from your friends.
  • Page 12: Battery And Charging

    Rockford amplifier without problems, although battery and alternator life can be reduced slightly. To maximize the performance of your Rockford Fosgate amplifier, we suggest the use of a heavy duty battery, high output alternator and an energy storage capacitor.

  • Page 14 6. Prepare the REM turn-on wire for connection to the amplifier by stripping 5/8" of insulation from the wire end and crimping an insulated spade connector in place. Slide the connector over the REM terminal on the amplifier. Connect the other end of the REM wire to a switched 12 volt positive source.
  • Page 15: Using The Xcard

    S I N G T H E The crossover functions are controlled through the use of an XCard and can be set for high-pass, low-pass or full range operation. The 100Hz XCard shipped with your amplifier is set for Full Range. Each crossover card has two faces: one face operates Full Range, the other has arrows to indicate the edge for selecting HP (high-pass) or LP (low- pass) operation.
