TOPAZ (Tracking Operation Pre-Amplifier Zone)

The TOPAZ (Tracking Operation Pre-Amplifier Zone) circuitry solvesground loop noise problems common to automotive amplifier design.This innovative new development allows vastly improved isolation ofthe input signal grounds from the power supply ground of theamplifier. This is accomplished by allowing the source unit to controlthe potential “environment” of the entire input structure or “zone” ofthe amplifier. This process improves the noise rejection of theamplifier by 30-40dB – an astounding 30-100 times better thanamplifiers without TOPAZ.

THE RESULT: Elimination of troublesome ground loop noise betweensource and amplifier.

TRANS•ANA(TRANSconductance Active Nodal Amplifier)

The TRANS•ANA (TRANSconductance Active Nodal Amplifier) is acircuit that allows the audio signal to pass through the amplifier at lowvoltage. The signal is directly level-shifted to the fixed high voltagerails via a pair of driver transistors. Signal linearity is assured by anactive node formed by the drive transistors at ultrasonic frequencies.This allows amplifier performance similar to trans•nova which ishighly stable and linear while utilizing the advantages of a non-floating power supply.

THE RESULT: An extended frequency bandwidth accurately suppliedto the output stages of the amplifier.

Pass-Thru OutputThe Pass-Thru output provides a convenient source for daisy-chain-ing an additional amplifier without the need for extra RCA cables or“Y” adapters. The Pass-Thru signal is derived from summing the Frontand Rear Left inputs to create a Left output, and summing the Frontand Rear Right inputs to create a Right output. When the amplifier isused with 4-channel inputs, the Pass-Thru provides constant outputregardless of the source unit fade position. Additionally, the Pass-Thru has an XCard that can be set for High-Pass, Low-Pass or Full Range.

THE RESULT: Constant non-faded output for adding woofer amplifiers.

DSM (Discrete Surface Mount) Technology

The DSM (Discrete Surface Mount) manufacturing process combinesthe advantages of both discrete components and integrated circuitry.Rockford Fosgate is the only American amplifier manufacturer to haveinvested millions into this process. DSM components differ fromconventional discrete components in three ways. They are morecompact, more rugged, and they efficiently dissipate generated heat.Using them wherever appropriate allows the advantages associatedwith discrete circuitry to be retained while also providing room forboth highly advanced processing features and generous PC boardcopper paths where needed. Their short lead-out structures allowmaximum audio performance and highest signal-to-noise ratios to beobtained in amplifiers of desirable package size without resorting to“amplifier-on-a-chip” shortcuts. These advantages are shown in Figure 1.

Surface MountThru-Hole

Solder SolderComponentFigure 1

THE RESULT: Fewer connections, improved reliability, shortersignal paths, superior signal-to-noise ratio and awesome sonicperformance.

XCard (Internal Crossover)The Punch amplifiers utilize internal active crossovers. Thesecrossovers have many performance advantages such as usingdiscrete components for exact frequency adjustments which arefar superior to potentiometers. Additionally, the XCard can beconfigured for high-pass, low-pass and full range operation. Withslight modifications, many crossover frequencies and slope con-figurations can be achieved.

THE RESULT: Increased system design flexibility with a preciseelectronic crossover without the limitations of conventionalpotentiometer designs.

NOMAD (NOn-Multiplying Advanced Decision)

The Punch amplifiers use an analog computer process to maximize safeoutput power under all operating conditions. Rockford Fosgate pio-neered and developed RTP (Real Time Protection), a crucial element inthe performance edge of our amplifiers. The innovative NOMAD (NOn-Multiplying Advanced Decision) system is the most sophisticated ver-sion of this technique ever used, bringing previously unavailable levelsof accuracy, stability, temperature immunity and reliability to thiscritical process. NOMAD makes advanced decisions based on devicevoltages to precisely control the awesome levels of current available inthe output MOSFETs to safe values – but only when absolutely needed.

THE RESULT: Extremely fast protection system that always protects theamplifier and never degrades the sound.

MOSFET DevicesRockford Fosgate is one of the few manufacturers in the soundcommunity to utilize MOSFET devices in both the power supply andthe output stages. MOSFET (Metal Oxide Semiconductor Field EffectTransistor) devices offer several important inherent advantages overthe 30 year old technology of bi-polar design. These advantagesinclude: thermal stability, switching speed, ultra low output imped-ance and wider bandwidth linearity. In addition, MOSFETs operatevery similar to vacuum tubes in which they are more linear thanbipolar transistors. However, MOSFETs can deliver the midrangeclarity without the limitations of transient response and high fre-quency phase shifting normally associated with tube operation.

THE RESULT: Operational characteristics similar to vacuum tubeswithout the performance limitations of tube designs.

INSTALLATION CONSIDERATIONS

This section focuses on some of the vehicle considerations for installingyour new Punch amplifier. Checking your battery and present soundsystem, as well as pre-planning your system layout and best wiring routeswill save installation time. When deciding how to lay out your newsystem, be sure that each component will be easily accessible for makingadjustments.

Before beginning any installation, be sure to follow these simple rules:

1. Be sure to carefully read and understand the instructions beforeattempting to install the amplifier.

2. For safety, disconnect the negative lead from the battery prior tobeginning the installation.

3. For easier assembly, we suggest you run all wires prior to mountingyour amplifier in place.

4. Route all of the RCA cables close together and away from any highcurrent wires.

5. Use high quality connectors for a reliable installation and to mini-mize 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 wiringwhen working on any vehicle.

7. Never run wires underneath the vehicle. Running the wires inside thevehicle provides the best protection.

8. Avoid running wires over or through sharp edges. Use rubber orplastic grommets to protect any wires routed through metal, espe-cially the firewall.

9. ALWAYS protect the battery and electrical system from damage withproper fusing. Install the appropriate fuseholder and 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 fromthe metal to ensure a good, clean ground connection. Groundingconnections should be as short as possible and always be connectedto metal that is welded to the main body, or chassis, of the vehicle.

The following is a list of tools you will need for installing the Punchamplifier:

Allen wrenches 9/64" & 3/32" (included) VoltmeterWire strippers Battery post wrenchElectric hand drill w/assorted bits Wire cuttersWire crimpers Assorted connectors

MOUNTING LOCATION

The mounting location and position of your amplifier will have a greateffect on its ability to dissipate the heat generated during normal opera-tion. The design of our cast aluminum heatsink serves to easily dissipatethe heat generated over a wide range of operating conditions. However,to maximize the performance of your amplifier, care should be taken toensure adequate ventilation.

Trunk MountingMounting the amplifier vertically on a surface with the fin grooves runningup and down will provide the best cooling of the amplifier.

Mounting the amplifier on the floor of the trunk will work but provides lesscooling capability than vertical mounting.

Mounting the amplifier upside down to the rear deck of the trunk will notprovide proper cooling and will severely affect the performance of theamplifier and is not recommended.

Passenger Compartment MountingMounting the amplifier in the passenger compartment will work as longas you provide a sufficient amount of air for the amplifier to cool itself. Ifyou are going to mount the amplifier under the seat of the vehicle, youmust 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 theamplifier's heatsink in the passenger compartment will not provide propercooling and will severely affect the performance of the amplifier and is notrecommended.

Engine Compartment MountingRockford Fosgate amplifiers should never be mounted in the enginecompartment. Not only will this void your warranty but could create anembarrassing situation caused by the ridicule from your friends.

Amplifiers will put an increased load on the vehicle's battery andcharging system. We recommend checking your alternator and batterycondition to ensure that the electrical system has enough capacity tohandle the increased load of your stereo system. Stock electrical systemswhich are in good condition should be able to handle the extra load ofany Rockford amplifier without problems, although battery and alterna-tor life can be reduced slightly. To maximize the performance of yourRockford Fosgate amplifier, we suggest the use of a heavy duty batteryand an energy storage capacitor.

BATTERY AND CHARGING

WIRING THE SYSTEM

CAUTION: Avoid running power wires near the low level input cables,antenna, power leads, sensitive equipment or harnesses. The power wirescarry substantial current and could induce noise into the audio system.

• For safety, disconnect the negative lead from the battery prior tobeginning the installation.

Configure the internal XCard crossovers prior to installation. (Refer topage 14 for more information.)

1. Plan the wire routing. Take care when running signal level RCA cablesto keep them close together but isolated from the amplifier's powercables and any high power auto accessories, especially electricmotors. This is done to prevent coupling the noise from radiatedelectrical fields into the audio signal. When feeding the wires throughthe firewall or any metal barrier, protect them with plastic or rubbergrommets to prevent short circuits. Leave the wires long at this pointto adjust for a precise fit at a later time.

2. Prepare the B+ cable for attachment to the amplifier by stripping 5/8"of insulation from the end of the wire. The use of 8 gauge power cablecan interfere with the installation of the end caps. Proper wire dresscan prevent this from occurring. To prevent the wire from fraying, stripthe insulation at a 45° angle. Insert the bared wire into the B+ terminalwith the long side of the insulation on the top. Bend the cable downat a 90° angle. Tighten the set screw to secure the cable in place.

– 9 –

3. Mount the fuseholder within 18" of the battery using two (2) #8screws. Disassemble the fuseholder. You should have 2 blackplastic end caps, 2 gold-plated fuse clips, a plastic spacer and thefuseholder body. Trim the amplifier power cable to reach thefuseholder and strip the wire 3/8". Slide one of the end caps overthe wire (narrow end first) and insert the wire into one of the fuseclips. Tighten the set screw. Screw the black end cap to thefuseholder body to secure the cable. Use the section of cable thatwas trimmed earlier and connect it to the other end of thefuseholder. Install the plastic spacer in the fuseholder and attachthe cable to the fuseholder body.

NOTE: The B+ cable MUST be fused 18" or less from the vehicle'sbattery. Install the fuseholder under the hood and prepare thecable ends as stated above. Connections should be water tight.

4. Strip 3/8" from the battery end of the power cable and crimp thelarge ring terminal to the cable. Use the ring terminal to connectto the battery positive terminal. Do not install the fuse at this time.

5. Prepare a length of cable to be used for the GND connection. Strip5/8" of insulation from the end of the cable as described previouslyand connect to the appropriate terminal of the amplifier. Preparethe chassis ground by scraping any paint from the metal surfaceand thoroughly clean the area of all dirt and grease. Strip the otherend of the wire and attach a ring connector. Fasten the cable to thechassis using a screw.

6. Prepare the REM turn-on wire for connection to the amplifier bystripping 1/4" of insulation from the wire end and crimping aninsulated spade connector in place. Slide the connector over theREM terminal on the amplifier. Connect the other end of the REMwire to a switched 12 volt positive source. The switched signal isusually taken from the source unit's auto antenna or the accessorylead. If the source unit does not have these outputs available, therecommended solution is to wire a mechanical switch in line witha 12 volt source to activate the amplifier.

7. Connect the source signal to the amplifier by plugging the RCAcables into the input jacks at the amplifier.

8. Connect the speakers. Strip the speaker wires 5/8" and insert intothe appropriate terminal on the amplifier. Insert the bared wire intothe speaker terminal and tighten the set screw to secure into place.Be sure to maintain proper speaker polarity. DO NOT chassisground any of the speaker leads as unstable operation may result.

9. Perform a final check of the completed system wiring to ensure thatall connections are accurate. Check all power and ground connec-tions for frayed wires and loose connections which could causeproblems.

After the final inspection is complete, install the power fuse andenjoy listening. During the initial listening period, you may needto “fine tune” any phasing and level settings within your particularvehicle. To aid in this procedure, play a track with high musicalcontent and cruise around your neighborhood. After fully evaluat-ing the transient response of your system and making any finaladjustments, all your neighbors within a 1 mile radius will assumethat you have just successfully completed another upgrade to youraudio system for which they will probably spill thumbtacks onyour driveway.

USING PASSIVE CROSSOVERS

A passive crossover is a circuit that uses capacitors and/or coils and isplaced on speaker leads between the amplifier and speaker. Thecrossover delegates a specific range of frequencies to the speaker foroptimum driver performance. A crossover network can perform one ofthree 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/octavesystems. These are easy to construct and require one component perfilter. Placing this filter in series with the circuit will reduce power tothe speaker by 6dB/octave above or below the crossover pointdepending on whether it is a high-pass or low-pass filter. Morecomplex systems such as 12dB/octave or 18dB/octave can causeimpedance problems if not professionally designed.

Passive crossovers are directly dependent upon the speaker's imped-ance and component value for accuracy. When passive crossovercomponents are used in multiple speaker systems, the crossover'seffect on the overall impedance should be taken into considerationalong with the speaker's impedance when determining amplifierloads. CAUTION: The Rockford Fosgate amplifiers are not recom-mended for impedance loads below 2Ω stereo and 4Ω bridged(mono) loads.

USING THE XCARD

The crossover functions are controlled through the use of an XCardand can be set for high-pass, low-pass or full range operation. Eachcrossover card has two faces: one face operates Full Range, the otherhas 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 theamplifier. Firmly, but carefully, plug the card into the socket.

The crossover point can be altered by changing the 4 resistor values.Use the following formula to select the appropriate resistor value tobe placed on the XCard.

DYNAMIC POWER MEASUREMENTS

About the Dynamic Power MeasurementsThe Audio Graph PowerCube is a test instrument used to measure theoutput of an amplifier in accordance with IHF-202 industry standards. TheIHF-202 standard is a dynamic power measurement and was developedas a means of measuring power in a manner that best represents the realworld operation of an amplifier. Many manufacturers, including RockfordFosgate, at times will measure amplifier power into a fixed resistor (4 ohm,2 ohm). While this method is useful in some types of evaluation andtesting, it is not representative of an amplifier that is connected to a speakerand playing music.

MusicMusic is dynamic; the sound waves are complex and constantly changing.In order to simulate this, the IHF-202 standard calls for the input signal tothe amplifier to be a 1kHz bursted tone. This signal is input (on for 20milliseconds) and reduced 20dB for 480 milliseconds. The signal isgradually increased in level until the amplifier's output exceeds 1% TotalHarmonic Distortion (THD). At 1% distortion becomes audible, therefore,any power produced above that level is considered not usable. Manymanufacturers represent their amplifiers' output power in excess of 10%distortion. They use many names for this measurement, such as TotalMaximum Power or Maximum Output Power. This is not indicative of theactual usable output power.

Listening to Loudspeakers - Not ResistorsA loudspeaker is not a resistor. A resistor's value (resistance measured inohms) is fixed. A loudspeaker's impedance is dynamic. It is constantlychanging in value, dependent upon the frequency of the input signal.Therefore, measuring power with the amplifier loaded into a 4 ohmresistor is not the same as measuring power with the amplifier connectedto 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 thanits nominal (printed) impedance. A speaker will also create phase shifts inthe signal that is passed through it. These phase shifts happen because aspeaker is an inductor (voice coil) and a capacitor (compliance of thesurround/spider), as well as a resistor (voice coil wire).

To simulate a speaker the Audio Graph PowerCube measures outputpower into 20 different loads. It tests at 8 ohms, 4 ohms, 2 ohms and 1ohm. Each of these impedances is also tested at –60°, –30°, 0°, +30° and+60° phase angles. These different impedances and phase angles repre-sent the shifts in impedance and phase that can occur in a typicalloudspeaker.

– 37 –

Information CubedThe data acquired in the testing procedure is then graphed in the form ofa 3-dimensional cube. Hence the name PowerCube.

The Phase Angle is expressed on the horizontal axis, the Output Voltageis presented on the vertical axis and the Impedance is displayed on the Zaxis. Output Power, in watts, is listed on the left hand side for eachimpedance at each phase angle.

What is an Amplifier?An amplifier by definition is a voltage generating device, recreating thesignal which is input to it identically but with increased volume. It will beconnected to a reactive load (the speaker). The impedance of this load andphase of the signal passing through the load will vary, dependent upon thefrequency of the input signal (music).

Therefore, a perfect amplifier will be able to maintain the same outputvoltage regardless of load characteristics and will not alter the signal it isreproducing. A perfect amplifier when measured by the AudioGraphPowerCube would present data that forms a perfect cube. Unfortunately,amplifiers are not perfect. The laws of physics generally prevent it. A greatamplifier 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!

Montage dans le coffreMonter l'amplificateur verticalement avec les rainures de haut en bas cequi lui permet de refroidir plus facilement.

Montage dans l'habitacleMonter l'amplificateur dans l'habitacle ne pose aucun problème, dumoment qu'il y ait assez d'air pour le refroidir. Si vous montez l'amplien dessous du siège, prévoyez 3 cm d'air autour du radiateur.

InstallationPour votre sécurité, déconnectez la borne négative de la batterie duvéhicule avant de commencer l'installation.

Terminal B+Il est impératif qu'il y ait un fusible sur le câble pour la connexion à lamasse. Préparez le châssis en grattant la peinture de la surface métalliqueet nettoyez la saleté et l'huile. Attachez le câble au châssis avec une vis.

Terminal GNDPréparez une longueur de câble pour la connexion à la masse. Préparezle châssis en grattant la peinture de la surface métallique et nettoyez lasaleté et l'huile. Attachez le câble au châssis avec une vis.

Terminal REMConnectez le fil REM à une commande 12 volts positive de la source. Lacommande 12 volts est habituellement prise sur la sortie antenneélectrique de la source ou la commande accessoire. Si la source nedispose pas de ces sorties, nous vous recommandons d'installer uninterrupteur qui fournira un positif 12 volts au REM de l'amplificateur.

EINBAUORT

EINLEITUNG

Im FahrzeugkofferraumDer vertikale Einbau der Endstufen, das bedeutet, daβ die Kühlrippenvon oben nach unten verlaufen, gibt dem Verstärker die beste Kühlung.

Auf der BeifahrerseiteSollte der Verstärker auf der Beifahrerseite montiert werden, so ist es sehrwichtig, für eine ausreichende Kühlung zu sorgen. Sollte der Verstärkerz.B. unter dem Beifahrersitz montiert werden, sollte dem Kühlkörpermindestens ein Luftspalt von 3 cm bleiben, um so für eine ausreichendeKühlung zu sorgen.

EinbauZur Sicherheit klemmen Sie den Negativ-Pol der Batterie während desgesamten Einbaues ab.

B+ AnschlussDie Plus-Leitung MUβ ca. 40 cm nach dem Plus-Pol der Batterie abgesichertsein. Preparieren Si die Kabellängen und montieren Sie den Sicherungshalter imMotorraum. ALLE Verbindungen müssen wasserdicht sein.

GND AnschlussPreparieren Sie Ihr Kabel für die Negativ Leitung (Erdung). PreparierenSie die Anschluβstelle des Erdungskabels, indem Sie das Metall gründlichreinigen und vom Lack befreien. Befestigen Sie nun die Erdung an dieserStelle mit einer Schraube.

Die Punch 400.4 ist ein 4-Kanal Verstärker, welcher 400 Watt RMSliefern kann. Dieser Verstärker hat einen 2/4-Kanal Schalter, um dieBenutzung eines Y-Adapters zu vermeiden. Vier interne Aktivweichen-Module erlauben es, den Verstärker optimal an alle Systeme anzupassen,ohne daβ Sie externe Prozessoren benötigen. Der Punch 400.4 ist einkraftvoller Verstärker, mit integrierten Besonderheiten, zu einemkonkurenzlos günstigen Preis.

Wir empfeheln Ihnen, Ihren neuen Verstärker, von einem unsererautorisierten Rockford Händler einbauen zu lassen. Sollten Sie denVerstärker selber einbauen, so beachten Sie bitte diese Hinweise, bevorSie mit dem Einbau beginnen.
