TECHNICAL DESIGN FEATURES

◆ TRANS•ANA

(TRANSconductance Active Nodal Amplifier)

The

TRANS•ANA

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•
highly stable and linear while utilizing the advantages of a non­floating power supply.

THE RESULT: An extended frequency bandwidth accurately supplied
to the output stages of the amplifier.

◆ TOP AZ (Tracking Operation Pre-Amplifier Zone)

The

TOPAZ

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.

◆ MOSFET Devices

Rockford Fosgate is one of the few manufacturers in the sound
community to utilize MOSFET devices in both the
the

output stages. MOSFET

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 similarly to vacuum tubes in which they are more linear than bi­polar 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.

◆ 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.

◆ 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.

◆ XCard Crossover

The 5.3x amplifiers utilize internal active crossovers. These cross­overs 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 modifica­tion, 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.

◆ Signal Switching Network

The Signal Switching Network allows the RCA input signals to be
distributed to the amplifier channels in many different configura­tions. Among the many possible configurations, one setting uses a
single RCA (L mono) to feed the subwoofer channel, thus simplifying
connections needed.

THE RESULT: Allows input signals to be distributed to amplifier
channels in many different configurations.

INSTALLATION CONSIDERATIONS

The following is a list of tools you will need for installing the amplifier:
Wire Cutters #2 Phillips Screwdriver

Wire Strippers Assorted wire connectors
Wire Crimpers Battery Post Wrench
Voltmeter Electric Hand Drill with assorted bits

This section focuses on some of the vehicle considerations for
installing your new 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 on the layout
of 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.

– 7 –

MOUNTING LOCATION

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 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

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.

BATTERY AND CHARGING

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:

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. Remove the cover and configure the internal XCard crossovers
prior to installation. Refer to “Using the XCard” (page 13) 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 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.

Avoid running power wires near the low level input

– 9 –

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.

4. 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.

5. 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.

6. 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.

7. 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.

8. Connect the source signal to the amplifier by plugging the RCA

cables/high level inputs into the input jacks at the amplifier.

9. 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.

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.

USING PASSIVE CROSSOVERS

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 Rockford Fosgate amplifiers are not recom-

mended 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. 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 (low­pass) operation. Orient the card with the desired operating edge,
indicated by the arrow, toward the socket terminals inside the ampli-

fier. Firmly, but carefully, plug the card into the socket.

High Level Input – “Single Ended” Type

This configuration is used for source units that have “Single Ended” speaker
outputs. Only the “+” output is “hot,” whereas the “–” or “common” are
common grounded. To verify your source unit has these outputs, connect an
ohm meter across the “–” output and radio chassis for a reading of 0Ω.

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
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.

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!
