TECHNICAL DESIGN FEATURES

◆ TRANS•ANA

(TRANSconductance Active Nodal Amplifier)

The

TRANS•ANA

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• highly stable and linear while utilizing the advantages of a nonfloating power supply.

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

◆ TOP AZ (Tracking Operation Pre-Amplifier Zone)

The

TOPAZ

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.

◆ MOSFET Devices

Rockford Fosgate is one of the few manufacturers in the sound community to utilize MOSFET devices in both the the

output stages. MOSFET

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 impedance and wider bandwidth linearity. In addition, MOSFETs operate very similarly to vacuum tubes in that they are more linear than bipolar 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.

◆ 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.

◆ NOMAD (NOn-Multiplying Advanced Decision)

All Rockford Fosgate amplifiers use an maximize safe output power under all operating conditions. The innovative 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.

◆ High Level Inputs

The high level inputs on the Rockford Fosgate amplifiers convert the speaker line outputs (high level) to preamp line inputs (low level). This allows amplifier compatibility with a variety of source units as well as the ability to integrate into factory systems without the need for external adapters.

THE RESULT: Allows compatibility with factory and aftermarket source units.

◆ XCard Crossover (2.6x & 4.6x)

The 2.6x and 4.6x 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 modification, 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.

INSTALLATION CONSIDERATIONS

The following is a list of tools you will need for installing the amplifier: Wire Cutters #2 Phillips Screwdriver

Wire Strippers Assorted wire connectors Wire Crimpers Battery Post Wrench Voltmeter Electric Hand Drill with assorted bits

This section focuses on some of the vehicle considerations for installing your new amplifier. 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 on the layout of 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 –

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 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

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.

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 performance of your Rockford Fosgate amplifier, we suggest the use of a heavy duty battery, high output alternator and an energy storage capacitor.

WIRING THE SYSTEM

CAUTION:

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. Remove the cover and configure the internal XCard crossovers prior to installation. Refer to “Using the XCard” (page 13) 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 1/2" of insulation from the end of the wire. Insert the bared wire into the B+ terminal and tighten the set screw to secure the cable in place.

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.

Avoid running power wires near the low level input

– 9 –

Trim the power cable within 18" of the battery and strip 1/2" of insulation from the end of the wire.

Cut the wire loop that is attached to the fuseholder in half and splice the fuse into the power line using appropriate inline connectors. Use the

section of cable that was trimmed earlier and connect it to the other end of the fuseholder.

4. Strip 1/2" 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 the Ground cable for attachment to the amplifier by stripping 1/2" of insulation from the end of the wire. Insert the bared wire into the GND terminal and tighten the set screw to secure the cable in place. 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 1/2" of insulation from the wire end. Insert the bared wire into the REM terminal and tighten the set screw to secure the cable into place. Connect the other end of the REM wire to a switched 12 volt positive source. The switched voltage 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.

Cut here

7. Securely mount the amplifier 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 1/2" and insert 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.

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 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 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 (lowpass) operation. Orient the card with the desired operating edge, indicated by the arrow, toward the socket terminals inside the ampli-

fier. Firmly, but carefully, plug the card into the socket.

DYNAMIC POWER MEASUREMENTS

About the Dynamic Power Measurements

The Audio Graph PowerCube is a test instrument used to measure the output of an amplifier in accordance with IHF-202 industry standards. 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 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.

What is an Amplifier?

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!

Leggere le seguenti istruzioni per l'installazione del prodotto. Evitare di seguire le istruzioni potrebbe risultare pericoloso per Voi e per il vostro veicolo.

INTRODUZIONE

Questo manuale offre informazioni sulle caratteristiche, sull'installazione, e sul funzionamento degli amplificatori Rockford Fosgate 2.3, 2.6x e 4.6x. Vi suggeriamo di conservare questo manuale per riferimento futuro.

Noi raccomandiamo fortemente di far installare il vostro nuovo amplificatore da un installatore autorizzato. Se invece preferite installare da soli il vostro amplificatore, assicuratevi di leggere l'intero manuale prima di cominciare.

POSIZIONAMENTO

Installazione nel bagagliaio

Montare l'amplificatore su una superficie verticale con le alettature dall'alto al basso servirà a raffreddare meglio l'amplificatore.

Posizionamento nell'abitacolo

L'amplificatore installato nell'abitacolo funzionerà se avrà a disposizione una quantità d'aria sufficiente per raffreddarlo. Se intendete montare l'amplificatore sotto un sedile del veicolo, è necessario avere al minimo una distanza di 2.5cm tra l'amplificatore e ciò che lo circonda.

INSTALLAZIONE

• Per ragioni di sicurezza, disconnettere il cavo negativo dalla batteria prima di iniziare l'installazione.

Terminale B+ positivo

La terminazione siglata B+ deve essere protetta da un fusibile posto a non più di 40cm dalla batteria del veicolo. Preparare il cavo ed installare il porta fusibile nel vano motore. I collegamenti devono essere a tenuta d'acqua.

Terminale GND Negativi

Preparate uno spezzone di cavo per la massa. Preparate il punto di massa togliendo la vernice dalla superficie del metallo ed eliminado sporcizia e grasso. Fissate il cavo al punto di massa impiegando un anello ed una vite.

Terminale REM Consenso

Connettere il terminale REM ad un segnale proveniente dal cavo antenna elettrica o accessori dell'autoradio. In caso questo segnale non sia disponibile, la soluzione più raccomandata è di cablare un interruttore su una sorgente 12 volt permanente per attivare l'amplificatore.
