◆TRANS•ANA
(TRANSconductance Active Nodal Amplifier)
The TRANS•ANA (TRANSconductance Active Nodal Amplifier) is a circuit
thatallows the audio signal to pass through the amplifier atlowvoltage.The
signalisdirectly level-shiftedtothefixedhigh voltagerailsviaapairofdriver
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
loopnoiseproblemscommontoautomotiveamplifierdesign.Thisinnovative
newdevelopmentallowsvastlyimprovedisolationoftheinputsignalgrounds
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: Eliminationof troublesome ground loop noisebetweensource
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
FosgateistheonlyAmericanamplifiermanufacturertohaveinvestedmillions
intothisprocess.DSMcomponentsdifferfromconventionaldiscretecompo-
nents in different ways. They are more compact, more rugged, and they
efficientlydissipate generated heat.Usingthem wherever appropriateallows
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. 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.
THERESULT: Allowscompatibilitywithfactoryandaftermarketsourceunits.

◆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
severalimportantinherentadvantagesoverthe30yearoldtechnologyofbi-
polar design. These advantages include: thermal stability, switching speed,
ultra low output impedance and wider bandwidth linearity. In addition,
MOSFETsoperateverysimilarly tovacuum tubesinthattheyare morelinear
thanbi-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 sophisticated version of
thistechniqueeverused,bringingpreviouslyunavailablelevelsofaccuracy,
stability,temperatureimmunityandreliabilitytothiscriticalprocess.NOMAD

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.

Thissectionfocuses 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
installationtime. Whendecidinghowtolayoutyournewsystem,besurethat
each component will be easily accessible for making adjustments.
Before beginning any installation, be sure to follow these simple rules:
1. Besuretocarefullyreadandunderstandtheinstructionsbeforeattempt-
ing to install the amplifier.
2. For safety, disconnect the negative lead from the battery prior to
beginning the installation.
3. Foreasierassembly,wesuggestyourunallwirespriortomountingyour
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 connec-
tions 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
Themountinglocationandpositionofyouramplifierwill haveagreateffect
on its ability to dissipate the heat generated during normal operation. The
design of our cast aluminum heatsink serves to easily dissipate the heat
generatedoverawiderangeofoperatingconditions.However,tomaximize
theperformance of youramplifier,care shouldbetaken to ensureadequate
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
aregoingtomounttheamplifierundertheseatofthevehicle,youmusthave
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
– 9 –
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,wesuggesttheuseofaheavydutybatteryandanenergystorage

W IRING THE S YSTEM
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.
•Forsafety,disconnectthenegativeleadfromthebatterypriortobeginning
the installation.
1. Plan the wire routing. Take care when running signal level RCA cables
tokeepthemclosetogetherbutisolatedfromtheamplifier'spowercables
and any high power auto accessories, especially electric motors. This is
doneto prevent coupling thenoisefromradiated electrical fields intothe
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"ofinsulationfromtheend ofthe wire.Insert thebaredwireintotheB+
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"ofinsulationfromtheendofthewire.InsertthebaredwireintotheGND
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. PreparetheREM turn-onwireforconnectiontotheamplifierbystripping
1/2" of insulation from the wire end. Insert the bared wire into the REM
terminalandtightenthesetscrewtosecurethecableintoplace.Connect
the other end of the REM wire to a switched 12 volt positive source. The
switchedvoltageisusuallytakenfrom thesource unit'sauto antennaor
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
speakerterminal and tighten the set screwto secureinto place. Besure

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.

U SING P ASSIVE C ROSSOVERS
Apassivecrossoverisacircuitthatusescapacitorsand/orcoilsandisplaced
onspeakerleadsbetweentheamplifierandspeaker.Thecrossoverdelegates
aspecificrangeoffrequenciestothespeakerforoptimumdriverperformance.
A crossover network can perform one of three functions: High-Pass (capaci-
tors),Low-Pass(inductorsorcoils)andBandpass(combinationofcapacitor
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/octavecancause impedance problems if not professionally designed.
Passivecrossoversaredirectlydependentuponthespeaker'simpedanceand
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
impedancewhendetermining amplifier loads. CAUTION: The Punch ampli-
fiersarenotrecommendedforimpedanceloadsbelow2Ωstereoand4Ω
