  • Page 5: Technical Design Features

    ECHNICAL ESIGN 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. was spared in design and construction from the unique circuitry design to the manufacturing process that has proven to be the industry reference for many years.
  • 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 (Metal Oxide Semiconductor Field Effect Transistor) Rockford Fosgate is one of the few manufacturers in any of the sound communities 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.
  • Page 8 E S I G N E AT U R E S Cast Aluminum Chrome 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.
  • Page 9 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. Internal Crossovers – These built-in crossover cards are configurable for a multitude of operating frequencies. The orientation of the card in its socket determines its function of high-pass, low-pass or full range operation.

    NSTALLATION ONSIDERATIONS Tools Needed The following is a list of tools you will need for installing the “50 Series” Power amplifiers: Allen wrenches 9/64" & 3/32" (included) Wire strippers Battery post wrench Electric hand drill and assorted bits This section focuses on some of the vehicle considerations for installing your new Punch amplifier. Checking your battery and present sound system, as well as pre-planning your system layout and best wiring routes will save installation time.
  • Page 13: Mounting Locations

    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 14: Wiring The System

    I R I N G Y S T E M 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.

    11. After the final inspection is complete, install the power fuse and enjoy listening. During the initial listening period, you may need to “fine tune” any phasing and level settings within your particular vehicle. To aid in this procedure, play a track with high musical content and cruise around your neighborhood.

  • Page 17: Using The Xcard

    SING THE 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 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.

(Power LED is on) Diagnosis Voltage applied to the REM terminal of the amplifier is not between 10.5 and 15.5 volts or there is no voltage present. Voltage to the B+ terminal of the amplifier is not between 10.5 and 15.5 volts or there is no voltage present.

Phase selection of amplifier incorrectly se- lected or speakers wired out of polarity from the left to right channel. XCards are missing or not placed properly in crossover slots and/or switches are not properly selected.
  • Page 45 Low battery voltage or large voltage drops to the amplifier under load. RCA cable or amplifier connected to Pass- Thru output is defective. • If noise persists, see your local Authorized Rockford Fosgate Dealer. Diagnosis Readjust input gains of amplifier. Check system with known working source and repair or replace original source as needed.

  • Page 48 The IHF-202 standard is a dynamic power measurement and was developed as a means of measuring power in a manner that best represents the Real World operation of an amplifier. Many manufacturers, including Rockford Fosgate, at times will measure amplifier power into a fixed resistor (4 ohm, 2 ohm). While this method is useful in some types of evaluation and testing, it is not representative of an amplifier that is connected to a speaker and playing music.
