GETTING STARTED

Welcome to Rockford Fosgate! This manual is designed to provide

informationfortheowner,salespersonandinstaller.Forthoseofyou

who want quick information on how to install this product, please

turn to the Basic Connections in the Installation section of this

manual. Other information can be located by using the Table of

Contents. We, at Rockford Fosgate, have worked very hard to make

sure all the information in this manual is current. But, as we are

constantlyfindingnewwaystoimproveourproduct,thisinformation

is subject to change without notice.

INTRODUCTION

ThePunch160x4 and240x4are4-channelamplifierswhichcan

deliver 160 watts and 240 watts RMS respectively. Both ampli-

fiers utilize a 2/4-channel input switch to eliminate the need for

signal splitters. A pair of internal XCard crossovers allow the

amplifiers to be configured for use with many popular system

designswithouttheaddedcostofexternalprocessors.ThePunch

160x4and 240x4are powerful 4-channel amplifiers with inte-

grated features which are offered at a competitive price.

We strongly recommend you have your Authorized Rockford

FosgateDealerinstallthenew Punchamplifier.If youdochoose

to install it yourself, please be sure to read the entire manual

before beginning.

ROCKFORD FOSGATE ACCESSORIES

Thefollowingaccessorieswere designed to enhance the perfor-

mance of the Punch 160x4and 240x4amplifiers.

Energy Storage Capacitor

ThePunchcapacitorsareusedtoprovideextracurrentneededby

amplifiers to reproduce musical transients. The Punch Caps also

havethenaturalabilitytofilterACripplecausedbythealternator,

reducing the chance of noise in the system. The Punch Caps will

maximizeboththesoundqualityandperformancethatRockford

Fosgate amplifiers can deliver.

Punch Link (FG-LINK)

The Punch Link is a specially cast heatsink interconnect which

allows you to join any of our current Punch or Punch Power

amplifiers together. While providing additional cooling through

thecouplingprocess, the PunchLink adds thefinishing touch by

giving you the look of one awesome amplifier.

XCard

Additional crossover card frequencies are available for special-

ized requirements. You can get the following XCards from your

Authorized Rockford Fosgate Dealer.

XM50 = 50Hz XM275 = 275Hz

XM70 = 70Hz XM400 = 400Hz

XM100 = 100Hz XM4.5k = 4,500Hz

XM150 = 150Hz XM6.5k = 6,500Hz

XM200 = 200Hz XM00 = Blank card for

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

amplifierat

low voltage

.Thesignal isdirectly level-shifted tothe

fixed high voltage rails via a pair of driver transistors. Signal

linearity is assured by an

active node

formed by the driver

transistorsatultrasonicfrequencies. Thisallowsamplifierperfor-

mance 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

amplifierdesign.Thisinnovativenewdevelopmentallowsvastly

improved isolation of the input signal grounds from the power

supplygroundoftheamplifier.Thisisaccomplishedbyallowing

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 com-

binestheadvantagesofbothdiscretecomponentsandintegrated

circuitry.RockfordFosgateistheonlyAmericanamplifiermanu-

facturertohaveinvestedmillionsintothisprocess.DSMcompo-

nents differ from conventional discrete components in three

ways.They aremore compact,more rugged,and theyefficiently

dissipate generated heat. Using them wherever appropriate al-

lows 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 “ampli-

fier-on-a-chip”shortcuts.TheseadvantagesareshowninFigure1.

THE RESULT: Fewer connections, improved reliability, shorter

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

performance.

◆XCard (Internal Crossover)

The Punch and Power amplifiers utilize internal active cross-

overs.Thesecrossovershavemanyperformanceadvantagessuch

as using discrete components for exact frequency adjustments

whicharefarsuperiortopotentiometers.Additionally,theXCard

can be configured for high-pass, low-pass and full range opera-

tion. 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

potentiometer designs.

◆RTP (Real Time Protection)

NOMAD (NOn-Multiplying Advanced Decision)

ThePunchandPoweramplifiersusean

analogcomputerprocess

maximize safe output power under all operating conditions. Rock-

ford Fosgate pioneered and developed

RTP

(Real Time Protection),

a crucial element in the performance edge of our amplifiers. The

innovative

NOMAD

(NOn-MultiplyingAdvancedDecision)system

is the most sophisticated version of this technique ever used,

bringing previously unavailable levels of accuracy, stability, tem-

perature 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.

◆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 impedance and wider bandwidth linearity. In

addition, MOSFETs operate very similar to vacuum tubes in

which they are more linear than bipolar transistors. However,

MOSFETscandeliverthemidrangeclaritywithoutthelimitations

oftransientresponse andhigh frequency phaseshifting normally

associated with tube operation.

THE RESULT: Operational characteristics similar to vacuum

tubes without the performance limitations of tube designs.

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 – Interchangeable end caps conceal the wiring and

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

3. SpeakerTerminals–Theheavyduty,gold-platedterminalblock

connectors (+ and –) will accept wire sizes from 8 AWG to 18

AWG. These gold-plated connectors are immune to corrosion

that can cause signal deterioration.

4. Power Terminals – The power and ground connectors on the

Punch amplifier are gold-plated and will accommodate up to 8

AWG wire maximizing the input current capability of the

amplifier.

5. REM Terminal – This spade terminal is used for the auto power/

remote turn-on of the Punch amplifier.
