◆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.

◆TOPAZ (Tracking Operation Pre-Amplifier Zone)

The

TOPAZ

(TrackingOperationPre-AmplifierZone)circuitry solves

Thisinnovativenewdevelopmentallowsvastlyimprovedisolationof

the input signal grounds from the power supply ground of the

amplifier.Thisisaccomplishedbyallowingthe sourceunitto control

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.

◆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 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 imped-

ance and wider bandwidth linearity. In addition, MOSFETs operate

very similarly to vacuum tubes in that they are more linear than bi-

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.

◆DSM (Discrete Surface Mount) Technology

The

DSM

(Discrete Surface Mount) manufacturingprocesscombines

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

◆NOMAD (NOn-Multiplying Advanced Decision)

All Rockford Fosgate amplifiers use an

analog computer process

maximize safe output power under all operating conditions. The

innovative

NOMAD

(NOn-Multiplying Advanced Decision) system

isthemostsophisticatedversionofthistechniqueeverused,bringing

previously unavailable levels of accuracy, stability, temperature

immunity and reliability to this critical process. NOMAD makes

advanceddecisionsbasedondevicevoltagestopreciselycontrolthe

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.

◆High Level Inputs

Thehighlevelinputs 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 (2.6x & 4.6x)

The2.6xand4.6xamplifiersutilizeinternalactivecrossovers.These

crossovers have many performance advantages such as using dis-

crete 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

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 poten-

tiometer designs.

1. Extruded Heatsink

The extruded aluminum heatsink of the RF amplifier dissipates

heat generated by the amplifier's circuitry.

2. Power/Speaker Barrier Strip

The barrier strip uses screw terminals that will accept #10 spade

lugs or bare speaker and power wire sizes from 10-18 AWG.

These gold-plated connectors are immune to corrosion that will

cause signal degradation.

3. RCA Input Jacks

The industry standard RCA jack provides an easy connection for

signal level input. They are gold-plated to resist the signal

degradation caused by corrosion.

4. High Level Inputs

The high level input connectors accept 1/8" spade lugs for the

connectionofasourceunitthathasonlyspeakerline(highlevel)

outputs.

5. Input Sensitivity Controls

The input level controls are preset for 500mV which will match

the output of most source units. They can be adjusted to match

output levels from a variety of source units.

6. Internal Crossover

The built-in crossover card is configurable for a multitude of

operating frequencies. The orientation of the card in its socket

determines its function of high-pass, low-pass or full range

operation.

7. LED Power Indicator

The LED gives a visual indication of the status of the amplifier,

lighting when the unit is turned on.

8. Bias Controls

The Bias controls are preset at the factory and are not user

adjustable. CAUTION! ANY ADJUSTMENT TO THE BIAS

CONTROLS WILL VOID YOUR WARRANTY!

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

wiringrouteswillsaveinstallationtime. Whendecidingonthelayout

of 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.
