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. This is matched with TOPAZ, a unique grounding circuit used to eliminate noise problems associated with car audio systems and their installation. Flexibility is accomplished with the use of a built-in XCard. Reliability is all but guaranteed with the use of a protection circuit called NOMAD, while MOSFET and DSM (Discrete Surface Mount) technology improve amplifier efficiency. The result of these components give the Punch amplifier awesome sound quality in a “Bullet Proof” package. An explanation of these technologies, most of which are exclusively designed and patented by Rockford, are described in the Technical Design Features. P UNCH A MPLIFIER A CCESSORY P ACK The accessory pack shipped with the Punch 2-channel amplifiers includes the mounting hardware necessary to secure the amp to the vehicle and to attach the end caps to the amplifier.

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 highly stable and linear while utilizing the advantages of a non-floating power supply. THE RESULT: An extended frequency bandwidth accurately supplied to the output stages of the amplifier. ◆ MEHSA (Maximum Efficiency Heat Sink Application) The MEHSA (Maximum Efficiency Heat-Sink Application) is a proprietary process that yields up to 5 times better heat transfer than traditional FET mounting techniques using the exact same components. A multi-layer insulated metal substrate operating with minimal thermal resistance spreads heat both downward & outward to quickly dissipate heat from each device across the heat sink. This process combined with our DSM technology and MOSFET devices allow us to squeeze more watts per cubic inch from every output device as well as provide consistent thermal stability. THE RESULT: Optimized power output, enhanced thermal stability, and maximum component reliability. ◆ TOPAZ (Tracking Operation Pre-Amplifier Zone) The TOPAZ (Tracking Operation Pre-Amplifier Zone) circuitry solves ground loop noise problems common to automotive amplifier design. This innovative new development allows vastly improved isolation of the input signal grounds from the power supply ground of the amplifier. This is accomplished by allowing the source unit to control the potential “environment” of the entire input structure or “zone” of the amplifier. This process improves the noise rejection of the amplifier by 30-40dB – an astounding 30-100 times better than amplifiers without TOPAZ. THE RESULT: Elimination of troublesome ground loop noise between source and amplifier. –2– ◆ 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 associated with discrete circuitry to be retained while also providing room for both highly advanced processing features and generous PC board copper paths where needed. Their short lead-out structures allow maximum audio performance and highest signal-to-noise ratios to be obtained in amplifiers of desirable package size without resorting to “amplifier-on-a-chip” shortcuts. These advantages are shown below in Figure 1. THE RESULT: Fewer connections, improved reliability, shorter signal paths, superior signal-to-noise ratio and awesome sonic performance. Figure 1 Component Solder PC Board Solder PC Board Thru-Hole Surface Mount ◆ XCard (Internal Crossover) The Punch amplifiers utilize internal active crossovers. These crossovers have many performance advantages such as using discrete components for exact frequency adjustments which are far superior to potentiometers. Additionally, the XCard can be configured for high-pass, low-pass and full range operation. With slight modifications, many crossover frequencies and slope configurations can be achieved. THE RESULT: Increased system design flexibility with a precise electronic crossover without the limitations of conventional potentiometer designs. –3– ◆ 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. In addition, MOSFETs operate very similarly to vacuum tubes in that they are more linear than bi-polar transistors. However, MOSFETs can deliver the midrange clarity without the limitations of transient response and high frequency phase shifting normally associated with tube operation. THE RESULT: Operational characteristics similar to vacuum tubes without the performance limitations of tube design. ◆ NOMAD (NOn-Multiplying Advanced Decision) The Punch amplifiers use an analog computer process to maximize safe output power under all operating conditions. The innovative NOMAD (NOnMultiplying Advanced Decision) system is the most sophisticated version of this technique ever used, bringing previously unavailable levels of accuracy, stability, temperature immunity and reliability to this critical process. NOMAD makes advanced decisions based on device voltages to precisely control the awesome levels of current available in the output MOSFETs to safe values – but only when absolutely needed. THE RESULT: Extremely fast protection system that always protects the amplifier and never degrades the sound. ◆ Punch EQ The Punch EQ helps correct for acoustical deficiencies in the listening environment. Two unique potentiometers that control bass and treble compensate for the response errors present in most car environments. Unlike conventional tone controls, Punch EQ corrects the specific problems of poor low bass response and high frequency rolloff. THE RESULT: Full range sound without excessive boost in areas where it is not needed. –4– 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.

Checking your battery and present sound system, as well as pre-planning your system layout and best wiring routes will save installation time. When deciding how to lay out your new system, be sure that each component will be easily accessible for making adjustments. Before beginning any installation, be sure to follow these simple rules: 1. Be sure to carefully read and understand the instructions before attempting to install the amplifier. 2. For safety, disconnect the negative lead from the battery prior to beginning the installation. 3. For easier assembly, we suggest you run all wires prior to mounting your amplifier in place. 4. Route all of the RCA cables close together and away from any high current wires. 5. Use high quality connectors for a reliable installation and to minimize signal or power loss. 6. Think before you drill! Be careful not to cut or drill into gas tanks, fuel lines, brake or hydraulic lines, vacuum lines or electrical wiring when working on any vehicle. 7. Never run wires underneath the vehicle. Running the wires inside the vehicle provides the best protection. 8. Avoid running wires over or through sharp edges. Use rubber or plastic grommets to protect any wires routed through metal, especially the firewall. 9. ALWAYS protect the battery and electrical system from damage with proper fusing. Install a fuseholder and appropriate fuse on the +12V power wire within 18” (45.7 cm) of the battery terminal. 10. When grounding to the chassis of the vehicle, scrape all paint from the metal to ensure a good, clean ground connection. Grounding connections should be as short as possible and always be connected to metal that is welded to the main body, or chassis, of the vehicle. –7– 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. Trunk Mounting Mounting the amplifier vertically on a surface with the fin grooves running up and down will provide the best cooling of the amplifier. Mounting the amplifier on the floor of the trunk will work but provides less cooling capability than vertical mounting. Mounting the amplifier upside down to the rear deck of the trunk will not provide proper cooling and will severely affect the performance of the amplifier and is strongly not recommended. Passenger Compartment Mounting Mounting the amplifier in the passenger compartment will work as long as you provide a sufficient amount of air for the amplifier to cool itself. If you are going to mount the amplifier under the seat of the vehicle, you must have at least 1" (2.54cm) of air gap around the amplifier's heatsink. Mounting the amplifier with less than 1" (2.54cm) of air gap around the amplifier's heatsink in the passenger compartment will not provide proper cooling and will severely affect the performance of the amplifier and is strongly not recommended. 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. –8– 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. To maximize the performance of your Rockford Fosgate amplifier, we suggest the use of a heavy duty battery and an energy storage capacitor. W IRING THE S YSTEM 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. • For safety, disconnect the negative lead from the battery prior to beginning the installation. 1. Configure the internal XCard crossovers prior to installation. Refer to “Using the XCard” (page 14) for further information. 2. Plan the wire routing. Take care when running signal level RCA cables to keep them close together but isolated from the amplifier's power cables and any high power auto accessories, especially electric motors. This is done to prevent coupling the noise from radiated electrical fields into the audio signal. When feeding the wires through the firewall or any metal barrier, protect them with plastic or rubber grommets to prevent short circuits. Leave the wires long at this point to adjust for a precise fit at a later time. 3. Prepare the Power cable for attachment to the amplifier by stripping 5/8" of insulation from the end of the wire. To prevent the wire from fraying, strip the insulation at a 45° angle. Insert the bared wire into the B+ terminal with the long side of the insulation on the top. Bend the cable down at a 90° angle. Tighten the set screw to secure the cable in place. –9– INSULATION STRIP WIRE > < 5/8" AMP > > > 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 225.2 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 section of cable that was trimmed earlier and connect it to the other end of the fuseholder. Install the plastic spacer in the fuseholder and attach the cable to the fuseholder body. NOTE: The B+ cable MUST be fused 18" or less from the vehicle's battery. Install the fuseholder under the hood and prepare the cable ends as stated above. Connections should be water tight. 4. Strip 3/8" from the battery end of the power cable and crimp a large ring terminal to the cable. Use the ring terminal to connect to the battery positive terminal. Do not install the fuse at this time. 5. Prepare a length of cable to be used for the ground connection. Strip 5/8" of insulation from the end of the cable as described previously and connect to the appropriate terminal of the amplifier. Prepare the chassis ground by scraping any paint from the metal surface and thoroughly clean the area of all dirt and grease. Strip the other end of the wire and attach a ring connector. Fasten the cable to the chassis using a non-anodized screw and a star washer. 6. Prepare the REM turn-on wire for connection to the amplifier by stripping 1/4" of insulation from the wire end and crimping an insulated spade connector in place. Slide the connector over the REM terminal on the – 10 – 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. Doing so may enable the screws to pull out from the panel due to road vibration or sudden vehicle stops. 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 all power and ground connections for frayed wires and loose connections which could cause problems. 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. After fully evaluating the transient response of your system and making any final adjustments, all your neighbors within a 1 mile radius will assume that you have just successfully completed another upgrade to your audio system for which they will probably spill thumbtacks on your driveway. – 11 – 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. These are easy to construct and require one component per filter. Placing this filter in series with the circuit will reduce power to the speaker by 6dB/octave above or below the crossover point depending on whether it is a high-pass or low-pass filter. More complex systems such as 12dB/octave or 18dB/octave can cause impedance problems if not professionally designed. Passive crossovers are directly dependent upon the speaker's impedance and component value for accuracy. When passive crossover components are used in multiple speaker systems, the crossover's effect on the overall impedance should be taken into consideration along with the speaker's impedance when determining amplifier loads. CAUTION: The Punch amplifiers are not recommended for impedance loads below 2Ω stereo and 4Ω bridged (mono) loads. – 12 – a d v a n c e d O p e r a t i o n a d v a n c e d TABLE OF CROSSOVER COMPONENT VALUES C L 6dB/Octave Low-Pass 6dB/Octave High-Pass Speaker Impedance Freq.

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. Firmly, but carefully, plug the card into the socket. ➝ LP ➝ Full Range ➝ ➝ HP Low-Pass HP High-Pass FULL ↕ LP The crossover point can be altered by changing all 4 resistor values.

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. Music Music is dynamic; the sound waves are complex and constantly changing. In order to simulate this, the IHF-202 standard calls for the input signal to the amplifier to be a 1kHz bursted tone. This signal is input (on for 20 milliseconds) and reduced 20dB for 480 milliseconds. The signal is gradually increased in level until the amplifier's output exceeds 1% Total Harmonic Distortion (THD). At 1% distortion becomes audible, therefore, any power produced above that level is considered unusable. Many manufacturers represent their amplifiers' output power in excess of 10% distortion. They use many names for this measurement, such as Total Maximum Power or Maximum Output Power. This is not indicative of the actual usable output power. Listening to Loudspeakers - Not Resistors A loudspeaker is not a resistor. A resistor's value (resistance measured in ohms) is fixed. A loudspeaker's impedance is dynamic. It is constantly changing in value, dependent upon the frequency of the input signal. Therefore, measuring power with the amplifier loaded into a 4 ohm resistor is not the same as measuring power with the amplifier connected to a 4 ohm speaker. Most people do not listen to music through a resistor. A 4 ohm speaker may experience a drop in impedance 4-6 times lower than its nominal (printed) impedance. A speaker will also create phase shifts in the signal that is passed through it. These phase shifts happen because a speaker is an inductor (voice coil) and a capacitor (compliance of the surround/spider), as well as a resistor (voice coil wire). To simulate a speaker the Audio Graph PowerCube measures output power into 20 different loads. It tests at 8 ohms, 4 ohms, 2 ohms and 1 ohm. Each of these impedances is also tested at –60°, –30°, 0°, +30° and +60° phase angles. These different impedances and phase angles represent the shifts in impedance and phase that can occur in a typical loudspeaker. – 29 – 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.

An amplifier by definition is a voltage generating device, recreating the signal which is input to it identically but with increased volume. It will be connected to a reactive load (the speaker). The impedance of this load and phase of the signal passing through the load will vary, dependent upon the frequency of the input signal (music). Therefore, a perfect amplifier will be able to maintain the same output voltage regardless of load characteristics and will not alter the signal it is reproducing. A perfect amplifier when measured by the Audio Graph PowerCube would present data that forms a perfect cube. Unfortunately, amplifiers are not perfect. The laws of physics generally prevent it. A great amplifier is about the best one can hope to attain. As you can see by the PowerCube and as you will experience by listening, your Punch amplifier is a GREAT AMPLIFIER! – 30 – – 31 – PUNCH 55.2 120 Watts 85 Watts Per channel into a 2Ω Load Per channel into a 4Ω Load 105 Watts 160 Watts 320 Watts PUNCH 75.2 Signal-to-Noise Ratio Crossover Slope Factory Default Crossover Frequency RMS continuous power mono into a 4Ω load from 20 to 20,000 Hz, with less than 0.1% Total Harmonic Distortion (THD) RMS continuous power per channel, both channels driven into a 2Ω load from 20 to 20,000 Hz, with less than 0.1% Total Harmonic Distortion (THD) RMS continuous power per channel, both channels driven into a 4Ω load from 20 to 20,000 Hz with less than 0.05% Total Harmonic Distortion (THD) 110 Watts 55 Watts 27.5 Watts 250 Watts 125 Watts 62.5 Watts 145 Watts 220 Watts 440 Watts PUNCH 125.2 > 100dB A-weighted 12dB/octave Butterworth 80Hz adjustable (.047µf) 150 Watts 75 Watts 37.5 Watts Continuous Power Rating (Competition Standard) - Measured at 13.8 Battery Volts 240 Watts Mono into a 4Ω Load Dynamic Power Rating (IHF-202 Standard) - Measured at 14.4 Volts S P E C I F I C AT I O N S 450 Watts 225 Watts 112.5 Watts 220 Watts 345 Watts 690 Watts PUNCH 225.2 – 32 – Input Impedance Equalization Fuse Type Battery Fusing Rates (External to Amplifier) Protection Input Sensitivity (+0dB gain overlap) Source Unit Compatibility (+15dB gain overlap) IM Distortion (IHF) Slew Rate Damping Factor @ 4Ω (at output connector ) 95/8" (24.4cm) W 139⁄32" (33.70cm) L 25/8" ( 6.6cm) H PUNCH 225.2 ATC ATC 40 amps 20k ohms Bass: +18dB Maximum at 45Hz Treble: +12dB Maximum at 20kHz ATC 30 amps Specifications are subject to change without notice. 20 amps AGU 50 amps NOMAD - Internal analog-computer output protection circuitry limits power in case of overload.

EINBAUORT Im Fahrzeugkofferraum Der vertikale Einbau der Endstufen, das bedeutet, dab die Kühlrippen von oben nach unten verlaufen, gibt dem Verstärker die beste Kühlung. Auf der Beifahrerseite Sollte der Verstärker auf der Beifahrerseite montiert werden, so ist es sehr wichtig, für eine ausreichende Kühlung zu sorgen. Sollte der Verstärker z.B. unter dem Beifahrersitz montiert werden, sollte dem Kühlkörper mindestens ein Luftspalt von 3 cm bleiben, um so für eine ausreichende Kühlung zu sorgen. Einbau Zur Sicherheit klemmen Sie den Negativ-Pol der Batterie während des gesamten Einbaues ab. B+ Anschluβ Die Plus-Leitung MUβ ca. 40 cm nach dem Plus-Pol der Batterie abgesichert sein. Preparieren Si die Kabellängen und montieren Sie den Sicherungshalter im Motorraum. ALLE Verbindungen müssen wasserdicht sein. – 39 – GND Anschluβ Preparieren Sie Ihr Kabel für die Negativ Leitung (Erdung). Preparieren Sie die Anschlubstelle des Erdungskabels, indem Sie das Metall gründlich reinigen und vom Lack befreien. Befestigen Sie nun die Erdung an dieser Stelle mit einer Schraube. REM Anschluβ Verbinden Sie das Ein-und Ausschaltungskontroll-Kabel mit Ihrem Radio (12 Volt positiv). Normalerweise verwenden Sie hierfür die Ant.-Remote Ihres Radios oder ein eigens dafür vorgesehenes Kabel (Amp-Remote). Sollte Ihr Radio diesen Anschlub nicht besitzen, so verwenden Sie eine 12 Volt Spannung, die Sie durch einen Schalter ein- und ausschalten können.

INTRODUZIONE Gli ingenieri Rockford hanno progettato la serie di amplificatori Punch.2 per resistere all'ostico ambiente automobilistico mentre suonano con una musicalitá superiore, offrendo un insieme versatile, affidabile ed efficiente. Trans•ana é un circuito a bassa tensione dello stadio preamplificatore del Punch.2 che permette al suono di essere cristallino e reale anche in presenza di volumi molto elevati…tutto questo é accoppiato TOPAZ, un exclusivo circuito di massa impiegato per eliminare i problemi di rumore comunemente presenti negli impianti car audio. Il massimo della versatilitá é raggiunto con l'impiego delle XCard. L'affidabilitá é completamente garantita dall'impiego di un circuito di protezione chiamato NOMAD, mentre l'uso di MOSFET e della tecnologia DSM (Discrete Surface Mount) permette di raggiungere efficienze elevatissime. Il risultato finale di tutte queste tecnnologie moderne é che gli amplificatori Punch suonano meravigliosamente e sono indistruttibili, a “prova di proiettile.” Una spiegazione di queste tecnologie innovative, molte coperte da brevetti Rockford, sono descritte in un'altra sezione di questo manuale. DOVE POSIZIONARLO Nel Bagagliaio Montando l'amplificatore su una superficie in verticale con le alette direzionate dall'alto verso il basso si garantirá un miglior raffreddamento dell'amplificatore. Nell'abitacolo Montare l'amplificatore nell'abitacolo si avrá un funzionamento regolare se si garantisce un flusso d'aria sufficiente. Per l'installazione sotto un sedile, é necessario avere uno spazio di almeno 3 cm attorno a tutto l'amplificatore. Installazione Per sicurezza, scollegare il polo negativo della batteria dell'auto prima di iniziare l'installazione. Terminale B+ (cavo positivo) Il cavo positivo deve essere protetto da un fusibile a non piú di 45 cm dalla batteria. Terminare il cavo e installare il fusibile nel vano motore. Tutte le connessioni devono essere a prova d'acqua. – 41 – Terminale GND (cavo negativo) Decidere la lunghezza del cavo e terminarlo. Preparare la massa grattando la vernice dal telaio dell'auto ed eliminando tracce di olio o sporco. Fissare il cavo di massa al telaio con una vite. Terminale REM (Consenso di accensione) Collegare il cavo REM ad un positivo presente solo ad autoradio accesa (normalmente il cavo pilota dell'antenna elettrica o il cavo accessori dell'autoradio). Se la sorgente non dovesse essere equipaggiata con queste uscite, la soluzione raccomandabile é di inserire un interruttore su un cavo positivo e connettersi all'amplificatore.
