Page 5: Introduction
N T R O D U C T I O N The Punch 160x deliver 160 watts and 240 watts RMS respectively. Both ampli- fiers utilize a 2/4-channel input switch to eliminate the need for signal splitters. A pair of internal XCard crossovers allow the amplifiers to be configured for use with many popular system designs without the added cost of external processors. -

ECHNICAL TRANS•ANA 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 driver transistors at ultrasonic frequencies. - Page 8 The DSM (Discrete Surface Mount) manufacturing process com- bines the advantages of both discrete components and integrated circuitry. Rockford Fosgate is the only American amplifier manu- facturer to have invested millions into this process. DSM compo- nents differ from conventional discrete components in three ways.
- Page 9 THE RESULT: Extremely fast protection system that always protects the amplifier and never degrades the sound. 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.

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 15 3. Punch 160x Trim the power cable to within 18" of the battery and install the protective rubber boot packed with the fuseholder over the end of the wire. Strip 3/8" of insulation from the wire and insert it into the end of the fuseholder, then crimp it in place. Slide the rubber boot into place to cover the connection.
- Page 16 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.

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. 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. -

Page 33: Dynamic Power Measurements
Many manufac- turers, 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. -
