 INTRODUCTION
Rockford engineers designed the Punch 40.2, 60.2, 100.2 and 200.2
amplifiers to withstand the rugged automotive environment while
delivering superior sound quality in a flexible, reliable, and efficient
package. 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. Reliabil-
ity is all but guaranteed with the use of a protection circuit called
NOMAD, while MOSFET and DSM (Discrete Surface Mount) tech-
nology 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.

 T ECHNICAL D ESIGN F EATURES

◆ 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
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.

◆ 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 ampli-
fier 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.

 ◆ 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.

PC
Board PC

Thru-Hole Surface Mount

THE RESULT: Fewer connections, improved reliability, shorter signal

paths, superior signal-to-noise ratio and awesome sonic performance.

◆ XCard (Internal Crossover)

The Punch amplifiers utilize internal active crossovers. These cross-
overs 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 potenti-
ometer designs.

 ◆ 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 vacuum tubes in which 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 (NOn-Multiplying 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 deci-
sions 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 cor-
rects 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.

The following is a list of tools you will need for installing the Punch
amplifier:
Allen wrenches 9/64" & 3/32" (included) Voltmeter
Wire strippers Battery post wrench
Electric hand drill w/assorted bits Wire cutters
17' (518.16cm) Red Power Wire Assorted connectors
12' (365.76cm) Remote Turn-On Wire Wire crimpers
1.5' (45.72cm) Black Grounding Wire
This section focuses on some of the vehicle considerations for
installing your new Punch 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 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.

 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 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 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.

 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.

WIRING THE SYSTEM

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 at- INSULATION

tion 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°

 Punch 40.2, 60.2, 100.2
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 200.2
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 ampli-
fier. 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 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 evalu-
ating 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.

USING PASSIVE CROSSOVERS

d p
v e
a r
a
n t
c i
e o
d n

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 imped-

ance 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.

 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 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.

 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 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 repre-
sent the shifts in impedance and phase that can occur in a typical
loudspeaker.

Downloaded from www.Manualslib.com manuals search engine
 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.

• Example of a Punch 200.2 PowerCube

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 gener-
ally 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!

INSTALACION DEL PRODUCTO. EVITARA POSIBLES DAÑOS A VD., AL
VEHICULO O AL PRODUCTO.

INTRODUCCION
Los ingenieros de Rockford han diseñado los amplificadores Punch.2
para ofrecer en el dificil entorno de un automóvil una calidad de sonido
superior en un producto flexible, fiable y eficiente. Trans•ana es un
circuito de baja tensión en la etapa de preamplificación de los
amplificadores Punch.2 que permite que la musica suene limpia y
cristalina y muy real, incluso a altos niveles de audicion. Esto se
complementa con el TOPAZ, un circuito exclusivo de masa utilizado
para eliminar los ruidos asociados con las instalaciones de car-audio. La
flexibilidad esta garantizada con el uso de la XCard incorporada. La
fiabilidad se refuerza con el uso de un circuito de proteccion llamado
NOMAD, mientras que los MOSFET y la tecnologia DSM (montaje
discreto en superficie) aumentan la eficiencia del amplificador. La
combinacion de todos estos componentes dan al amplificador Punch
una impresionante calidad de sonido en un chasis discreto. Mas
adelante encontrará mas explicaciones de todas estas tecnologías, la
mayoria de ellas usados en exclusiva y patentadas por Rockford.

INTRODUCTION
Les ingénieurs de Rockford Fosgate ont conçu l'amplificateur Punch.2
pour supporter l'environnement rude de l'automobile en délivrant une
qualité de son supérieure dans un ensemble efficace, fiable et flexible.
Trans•ana est un circuit de bas voltage dans l'étage de préamplification
de tous les ampificateurs Punch.2 qui reproduit un son musical clair
comme du cristal et très réel, même à très haut volume. Ceci est
accompagné du TOPAZ, un circuit unique employé pour éliminer les
problèmes de bruits parasites associés aux systémes audiomobile et leur
installation. La flexibilité est assurée par l'emploi d'une XCard incorporée.

La fiabilité est garantie grâce au circuit de protection NOMAD, la

technologie MOSFET et DSM (Composants Montés en Surface) améliorent
l'efficacité de l'amplificateur.

L'ensemble de ces atouts donne à l'amplificateur Punch une qualité de

son inégalable sous une carrosserie “pare-balles.”

Vous trouverez de plus amples informations sur ces technologies,

exclusivement conçues et brevetées par Rockford, dans la rubrique
technique.
MONTAGE
Montage dans le coffre
Monter l'amplificateur verticalement avec les rainures de haut en bas ce
qui lui permet de refroidir plus facilement.

Montage dans l'habitacle

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

Installation
Pour votre sécurité, déconnectez la borne négative de la batterie du
véhicule avant de commencer l'installation.

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

 BITTE LESEN SIE DIESE GEBRAUCHSANLEITUNG ZUERST SORGFÄLTIG
DURCH. DAS KANN SIE VOR DEM FALSCHEN EINSATZ, AUSFALLEN
ODER SOGAR BESCHÄDIGUNG DES PRODUKTES ODER IHRES
FAHRZEUGES SCHÜTZEN.

EINLEITUNG
Rockford Ingenieure haben die Punch.2 Verstärker entwickelt. Mit
höchstem Technologie-Standart, hervorragender Klangqualität, einfacher
Handhabung und bester Servicefreundlichkeit Trans•ana ist eine Nieder-
Volt Schaltung im Vorverstärkerteil aller Pünch.2 Verstärker die für
kristallklaren Klang auch bei sehr hohen Lautstärken sorgt. TOPAZ, eine
einzigartige Erdungsschaltung verhindert und unterdrückt Einstreuungen
und Störungen die nur allzu oft Car Audio Systeme beeinträchtigen.
Flexibilität durch die Vielfalt der Aktivweiche mit ihren XCards, lange
Lebensdauer durch die Schutzschaltung NOMAD und der Einsatz von
MOSFET Transistoren und DSM (Discrete Surface Mount), machen
diese Verstärker so effizient. Das Ergebnis all dieser Komponenten
machen Punch-Verstärker so einzigartig und in ihrer Klangqualität
nahezu unschlagbar. Eine genauere Beschreibung dieser Technologien,
die gröβtenteils einzigartig und von Rockford patentiert sind, finden Sie
unter Technical Design Features.

EINBAUORT
Im Fahrzeugkofferraum
Der vertikale Einbau der Endstufen, das bedeutet, daβ 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+ Anschluss
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.

 GND Anschluss
Preparieren Sie Ihr Kabel für die Negativ Leitung (Erdung). Preparieren
Sie die Anschluβstelle des Erdungskabels, indem Sie das Metall
gründlich reinigen und vom Lack befreien. Befestigen Sie nun die
Erdung an dieser Stelle mit einer Schraube.

REM Anschluss
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 Anschluβ 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.

 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.
