NTRODUCTION

Rockford engineers designed the Punch 100.2 and Punch 120.2 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 .1 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 crossover.
The use of a protection circuit called NOMAD, along with MOSFET and DSM
(Discrete Surface Mount) technologies 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.

◆ 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.

◆ TOP AZ (T racking 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.

◆ 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

◆ 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.

◆ 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

(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 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 Bass

The Punch Bass helps correct for acoustical deficiencies in the listening
environment. This unique circuit compensate for the response errors present
in most car environments. The Punch Bass helps reproduce full range sound
without providing excessive boost in areas where it is not needed.

THE RESULT: Provides better low bass response.

6. High Level Inputs – The high level inputs use a detachable connector
terminated with 20 AWG leads. These inputs should be used if the source
unit has only speaker line (high level) outputs and not RCA outputs.

7. Gain Control – The input gain control is preset to match the output of
most source units. They can be adjusted to match output levels from a
variety of source units.

8. RCA Pass-Thru Jacks – The Pass-Thru provides a convenient source for
daisy-chaining an additional amplifier without running on extra set of
RCA cables from the front of the vehicle to the rear amplifier location. One
of the internal XCards can be designated to the Pass-Thru, creating a
dedicated low-pass, high-pass, or full range output.

9. Punch Bass – The Punch Bass control helps correct for acoustical
deficiencies in the listening environment. The Punch Bass allows a
narrow band adjustment at 45Hz to help reproduce full range sound
without excessive boost.

10. Variable Crossover – The amplifiers have a built-in 12dB/octave
Butterworth filter with a crossover point variable from 50Hz to 210Hz.
The crossover can be set to Low-Pass (LP) or it can be bypassed by
setting it to Full Range (FULL).

11. LED Power Indicator – The LED illuminates when the unit is turned on.

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.

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.

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.

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. 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.

2. 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.

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.

3. 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.

4. 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.

5. 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.

6. 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.

7. Connect the source signal to the amplifier by plugging the RCA cables/

high level inputs into the input jacks at the amplifier.

8. 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.

9. 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.

ROSSOVERS

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 ampli-

fiers are not recommended for impedance loads below 2Ω stereo and 4Ω
bridged (mono) loads.

EASUREMENTS

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 represent the shifts in impedance
and phase that can occur in a typical loudspeaker.

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.

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!

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

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

NTRODUZIONE

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.

D

OVE POSIZIONARLO

– 34 –

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.
