INTRODUCTION
Rockford engineers designed the Punch 2-channel amplifiers to
withstand the rugged automotive environment while delivering
superior sound quality in a flexible, reliable, and efficient pack-
age. A grounding technique called TOPAZ was used to eliminate
noise problems associated with car audio systems, while flexibil-
ity was accomplished with the use of a built-in XCard. Reliability
was accomplished with the use of protection circuits called RTP
and NOMAD, while MOSFET and DSM technology 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, some exclusively
designed by Rockford, are described in the Technical Design
Features.

ROCKFORD FOSGATE ACCESSORIES
The following accessories were designed to enhance the perfor-
mance of the Punch 2-channel amplifiers.
Energy Storage Capacitor
The Punch capacitors are used to provide extra current needed by
amplifiers to reproduce musical transients. The Punch Caps also
have the natural ability to filter AC ripple caused by the alternator,
reducing the chance of noise in the system. The Punch Caps will
maximize both the sound quality and performance that Rockford
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
the coupling process, the Punch Link adds the finishing 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
custom crossover

TECHNICAL DESIGN FEATURES
◆ TOP AZ (Tracking 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.
◆ RTP (Real Time Protection)
NOMAD (NOn-Multiplying Advanced
Decision)
The Punch and Power amplifiers use an
analog computer
process
to maximize safe output power under all operating
conditions. Rockford Fosgate pioneered and developed
RTP
(Real Time Protection), a crucial element in the performance
edge of our amplifiers. The innovative
NOMAD
(NOn-Multiply-
ing Advanced Decision) system is the most sophisticated version
of this technique ever used, bringing previously unavailable
levels of accuracy, stability, temperature immunity and reliabil-
ity 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.

◆ DSM (Discrete Surface Mount) Technology
The
DSM
(Discrete Surface Mount) manufacturing process com-
bines the advantages of both discrete components and integrated
circuitry. Rockford Fosgate is the only American amplifier manu-
facturer to have invested millions into this process. DSM compo-
nents differ from conventional discrete components in three
different ways. They are more compact, more rugged, and they
take much better advantage of the PC board to allow them to get
rid of any heat they generate. 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 “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.

◆ XCard (Internal Crossover)
The Punch and Power 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 config-
ured for high-pass, low-pass and full range operation. 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 poten-
tiometer 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
(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 and vacuum tubes share many important
operating characteristics. However, the MOSFET device is much
faster, wider in bandwidth, measurably lower in distortion and far
more linear than vacuum tubes.
THE RESULT: Operational characteristics of vacuum tubes
without the performance limitations of tube design.
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. Speaker Terminals – The heavy duty, gold-plated terminal block
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 AP (auto
power) or remote turn on of the Punch amplifier.

6. RCA Input Jacks – The industry standard RCA jacks provide
easy connections for signal level input. They are gold-plated to
resist the signal degradation caused by corrosion.
7. Input Sensitivity Controls – The input level controls are preset
for 825mV which will match the output of most source units.
They can be adjusted to match input levels ranging from 150mV
to 3V.
8. Punch Equalization Controls – The Punch EQ helps correct for
acoustical deficiencies of 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 18dB 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.
