INTRODUCTION The Punch 360.6, is a 360 watt, 6 channel amplifier with integrated features for accommodating “single amplifier” system designs. Built into the amplifier are four internal XCards and a Signal Switching Network. These features simplify signal processing and enable custom signal distribution for each set of channels. Also integrated is a Phase Switch and Bass EQ circuit designed to improve system tuning. The engineering effort applied to the Punch 360.6 amplifier represents how an im

TECHNICAL DESIGN FEATURES u 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

u 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

u 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

360.6 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 – The unique end caps conceal the wiring and input cables, giving the amplifier a clean “stealth” look. R R R LED + L – + R – Ch. C Ch. C Ch. B Ch. A L L L Gain Gain Ch. C Bass EQ Gain Ch.

8. 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. 9. Bass EQ Control – The Bass EQ allows a narrow band adjustment of up to +18dB centered at 45Hz. The bass boost can be bypassed by turning the control to its minimum or counterclock- wise position. The Bass EQ is dedicated for “Channel C” only. 10. Internal Crossovers – These built-in crossover cards are con

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

Mount the fuseholder within 18" of the battery using two (2) #8 screws. Disassemble the fuseholder. You should have 2 black plastic end caps, 2 gold-plated fuse clips, a plastic spacer and the fuseholder body. Trim the amplifier power cable to reach the fuseholder and strip the wire 3/8". Slide one of the end caps over the wire (narrow end first) and insert the wire into one of the fuse clips. Tighten the set screw. Screw the black end cap to the fuseholder body to secure the cable. Use the sect

8. Connect the source signal to the amplifier by plugging the RCA cables into the input jacks at the amplifier. 9. Connect the speakers. Strip the speaker wires 5/8". Insert the bared wire into the speaker terminal and tighten the set screw to secure into place. Be sure to maintain proper speaker polarity. DO NOT chassis ground any of the speaker leads as unstable operation may result. 10. Perform a final check of the completed system wiring to ensure that all connections are accurate. Check a

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 XCard installed in 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. Firml

RESISTOR CHART 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.
