INTRODUCTION Rockford engineers designed the Punch 40x , 60x , 100x and 2 2 2 200x amplifiers to withstand the rugged automotive environment 2 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 amplifiers that lets the music sound crystal clear 2 and very real, even when played at high volume levels. This is matched with TOPAZ, a unique grounding circuit used to eliminate noise problems a

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. This allows amplifier performance similar to trans•nova which is hig

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. Using them wherever appropriate allows the advantages ass

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. These advantages include: thermal stability, switching speed, ultra low output imped- ance and wider bandwidth linearity. In addition, MOSFETs operate very similarly to vacuu

DESIGN 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 – Interchangeable end caps conceal the wiring and input cables, giving the amplifier a clean “stealth” look. 3 8 7 6 6 7 3 8 Speaker Speaker +L – +R – Left Left Right Right Treble Bass Gain Input Input Gain 9 5 4 11 LED

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. 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. The Punch EQ ca

MOUNTING LOCATION 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 condi- tions. However, to maximize the performance of your amplifier, care should be taken to ensure adequate ventilation. Trunk Mounting Mounting the amplifier vertically on a surface with the fin grooves running

> > > BATTERY AND CHARGING 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. To maximize the perfo

Punch 40x , 60x , 100x 2 2 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 200x 2 Mount the fuseholder within 18" of the b

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. 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 mech

USING THE XCARD 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. Orient the card with the desired operating edge, indicated by the arrow, toward the socket terminals inside the ampli- fi
