TABLE CONTENTS OF Introduction ................................................................................................ 1 Punch Amplifier Accessory Pack ................................................................... 1 Technical Design Features ............................................................................ 2 Design Features .......................................................................................... 5 Installation Considerations ....................................
INTRODUCTION Rockford engineers designed the Punch 55.2, 75.2, 125.2 and 225.2 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 .2 amplifiers that lets the music sound crystal clear and very real, even when played at high volume levels.
TECHNICAL DESIGN FEATURES ◆ 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.
◆ DSM (Discrete Surface Mount) Technology 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.
◆ 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 bipolar design. These advantages include: thermal stability, switching speed, ultra low output impedance and wider bandwidth linearity.
D ESIGN FEATURES 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 – The unique end caps conceal the wiring and input cables, giving the amplifier a clean “stealth” look.
7. 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. 8. Punch Equalization Controls – The Punch EQ helps correct for acoustical deficiencies in the listening environment. The Bass control allows a narrow band adjustment of up to 18dB centered at 45Hz. The Treble control is a wide band hinged adjustment with a maximum of 12dB at 20kHz.
I NSTALLATION C ONSIDERATIONS The following is a list of tools you will need for installing the Punch amplifier: Allen wrenches 9/64" & 3/32" (included) Voltmeter Wire strippers Battery post wrench Electric hand drill w/assorted bits Wire cutters 17' (518.16cm) Red Power Wire Assorted connectors 12' (365.76cm) Remote Turn-On Wire Wire crimpers 1.5' (45.72cm) Black Grounding Wire This section focuses on some of the vehicle considerations for installing your new Punch amplifier.
M OUNTING L OCATION The mounting location and position of your amplifier will have a great effect on its ability to dissipate the heat generated during 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 amplifier, care should be taken to ensure adequate ventilation.
B ATTERY AND C HARGING Amplifiers will put an increased load on the vehicle's battery and charging system. We recommend checking your alternator and battery condition to ensure that the electrical system has enough capacity to handle the increased load of your stereo system. Stock electrical systems which are in good condition should be able to handle the extra load of any Rockford amplifier without problems, although battery and alternator life can be reduced slightly.
Punch 55.2, 75.2, 125.2 Trim the power cable to within 18" of the battery and install the protective rubber boot, which is packed with the fuseholder, over the end of the wire. Strip 3/8" of insulation from the wire and insert into the end of the fuseholder, then crimp it in place. Slide the rubber boot into place to cover the connection. Use the section of cable that was trimmed earlier and connect it to the other end of the fuseholder. Punch 225.
amplifier. Connect the other end of the REM wire to a switched 12 volt positive source. The switched signal is usually taken from the source unit's auto antenna or the accessory lead. If the source unit does not have these outputs available, the recommended solution is to wire a mechanical switch in line with a 12 volt source to activate the amplifier. 7. Securely mount the amplifier (with supplied screws) to the vehicle or amp rack. Be careful not to mount the amplifier on cardboard or plastic panels.
USING PASSIVE CROSSOVERS 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-Pass (inductors or coils) and Bandpass (combination of capacitor and coil). The most commonly used passive crossover networks are 6dB/octave systems.

U SING XCARD 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. Orient the card with the desired operating edge, indicated by the arrow, toward the socket terminals inside the amplifier.
a d v a n c e d R ESISTOR C HART Our tests have shown that using 0.047µf capacitors for frequencies below 100Hz, and 0.022µf capacitors for frequencies above 100Hz, result in more linear crossover control. Refer to the Specifications page to determine the capacitor value of each supplied XCard.

The capacitors also have the natural ability to filter AC ripple caused by the alternator, reducing the chance of noise in the system. The Punch Caps are available in a variety of values and will maximize both the sound quality and performance that Rockford Fosgate amplifiers can deliver.

D YNAMIC P OWER M EASUREMENTS About the Dynamic Power Measurements The Audio Graph PowerCube is a test instrument used to measure the output of an amplifier in accordance with IHF-202 industry standards. 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).
Information Cubed The data acquired in the testing procedure is then graphed in the form of a 3-dimensional cube, hence the name PowerCube. The Phase Angle is expressed on the horizontal axis, the Output Voltage is presented on the vertical axis and the Impedance is displayed on the Z axis. Output Power, in watts, is listed on the left hand side for each impedance at each phase angle.
