GETTING STARTED

INTRODUCTION

Rockford engineers designed the Punch 40.2, 60.2, 100.2and 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 .2amplifiers 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.

Flexibilityis accomplished with theuseofa 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-

nologyimproveamplifierefficiency.Theresultofthesecomponents

give the Punch amplifier awesome sound quality in a “Bullet Proof”

package. An explanation of these technologies, most of which are

exclusivelydesignedand patentedbyRockford,aredescribedinthe

◆TRANS•ANA

(TRANSconductance Active Nodal Amplifier)

The

TRANS•ANA

(TRANSconductance Active Nodal Amplifier) is a

circuitthatallowstheaudiosignaltopassthroughtheamplifieratlow

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.

Thisinnovativenewdevelopmentallowsvastlyimprovedisolationof

the input signal grounds from the power supply ground of the

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.

◆DSM (Discrete Surface Mount) Technology

The

DSM

(Discrete Surface Mount) manufacturing process combines

the advantages of both discrete components and integrated circuitry.

RockfordFosgateistheonlyAmericanamplifiermanufacturertohave

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

maximumaudioperformanceandhighestsignal-to-noiseratios tobe

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,superiorsignal-to-noiseratioandawesomesonicperformance.

◆XCard (Internal Crossover)

The Punch amplifiers utilize internal active crossovers. These cross-

overs have many performance advantages such as using discrete

componentsforexactfrequencyadjustmentswhicharefarsuperiorto

potentiometers. Additionally, the

XCard

can be configured for high-

pass, low-pass and full range operation. With slight modifications,

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

(MetalOxideSemiconductor FieldEffect

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

verysimilarly to vacuumtubesin whichtheyare more linearthanbi-

polartransistors.However,MOSFETscandeliverthemidrangeclarity

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

sophisticatedversionofthistechniqueeverused,bringingpreviously

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

levelsofcurrentavailableintheoutputMOSFETstosafevalues–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

listeningenvironment.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.

DESIGN FEATURES

1. Cast Aluminum Heatsink –The cast aluminum heatsink of the

Punch amplifier dissipates heat generated by the amplifier's

circuitry. The inherent advantage of casting provides a 30%

improvement of cooling over conventional extrusion heatsink

designs.

2. End Caps –The unique end caps conceal the wiring and input

cables, giving the amplifier a clean “stealth”look.

7. Input Sensitivity Controls –The input level controls are preset

tomatchtheoutput of most source units. They can be adjusted

to match output levels from a variety of source units.

8. Punch Equalization Controls –ThePunchEQhelpscorrect for

acoustical deficiencies in the listening environment. The Bass

control allows a narrow band adjustment of up to 18dB

centered at 45Hz. The Treble control is a wide band hinged

adjustment with a maximum of 12dB at 20kHz. The Punch EQ

can be bypassed by turning the controls to their minimum or

counterclockwise position.

9. LED Power Indicator –The LED illuminates when the unit is

turned on.

10. XCard (Internal Crossover) –This built-in crossover card is

configurable for a multitude of operating frequencies. The

orientation of the card in its socket determines the function of

high-pass, low-pass, or full range operation.

This section focuses on some of the vehicle considerations for

installing your new Punch amplifier. Checking your battery and

presentsoundsystem,aswellaspre-planningyoursystemlayoutand

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.

Beforebeginninganyinstallation,besuretofollowthesesimplerules:

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. RoutealloftheRCAcablesclosetogetherandawayfromanyhigh

current wires.

5. Use high quality connectors for a reliable installation and to

minimize signal or power loss.

6. Thinkbeforeyoudrill! Becarefulnottocutordrillintogastanks,

fuel lines, brake or hydraulic lines, vacuum lines or electrical

wiring when working on any vehicle.

7. Neverrunwiresunderneaththevehicle. Runningthewiresinside

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+12Vpowerwirewithin18”(45.7cm)ofthebatteryterminal.

10. When grounding to the chassis of the vehicle, scrape all paint

from the metal to ensure a good, clean ground connection.
