NTRODUCTION

The PA2 is a stereo 4-band equalizer and preamplifier used to compensate
for differences in music format and to correct for response problems
associated with mobile audio installations.

Two different sources can be fed into the PA2 and independently selected
using the front panel A/B input switch. All input and output connections are
made via gold-plated RCA jacks. Inputs are monitored utilizing signal present
and signal clipping LEDs and can be level matched using the input gain
controls. Three pairs of outputs (Front, Rear and Subwoofer) can be adjusted
using the front/rear fader and subwoofer volume controls. A master volume
control adjusts the overall output level.

Each EQ band can accommodate up to 10dB boost or cut to compensate
for insufficient bass response, excessive mid-bass, and high frequency roll
off. The low frequency EQ center is variable from 40Hz to 80Hz, the midrange
controls are centered at 250Hz and 1kHz, and a special high frequency
hinge filter spans from 1kHz-20kHz.

The PA2 packs powerful features into its small but stylish 1/2 DIN size, and
its red/green backlighting allows for easy integration into any automobile,
making it a great addition for center consoles or in-dash use.

1. A/B Input Switch – Selects between two different sources fed into the
preamp. Sources can be designated as CD/TAPE, CD/VCR AUDIO, CD/
VIDEO GAME AUDIO, etc.

2. Signal Strength/Clipping LED – Illuminates red when a predetermined
threshold is reached. Refer to “clipping LED trim potentiometer” for setup
options.

3. Signal Present LED – Illuminates green when signal is detected on any
of the inputs.

4. Master Volume Control – Controls the overall output amplitude of the
front/rear/subwoofer outputs. The control can be set to its full counter­clockwise position for zero output or its full clockwise position for
maximum output.

5. Front/Rear Fader – Attenuates the front or rear outputs for the desired
“front stage/rear fill” effect. When set to the rear position, the rear output
level is maintained and the front output level is attenuated. When set to
the front position, the front output level is maintained and the rear output
level is attenuated.

6. Subwoofer Volume Control – Controls the signal amplitude of the
subwoofer outputs.

7. Subwoofer Frequency – Selects the center frequency for the subwoofer
boost/cut control.

8. Subwoofer Boost/Cut – Increases or decreases the amplitude of the
subwoofer center frequency. The control is set to flat (0dB) when
adjusted to its center detent position.

9. 250Hz Boost/Cut – Increases or decreases the amplitude of the 250Hz
center frequency. The control is set to flat (0dB) when adjusted to its
center detent position.

10. 1kHz Boost/Cut – Increases or decreases the amplitude of the 1kHz
center frequency. The control is set to flat (0dB) when adjusted to its
center detent position.

11. 1kHz-20kHz Hinge Filter – Increases the amplitude of the high
frequency hinge filter. The control is set to flat (0dB) when adjusted to
its full counterclockwise position. Maximum boost at 20kHz occurs
when adjusted to its full clockwise position.

12. RCA Input/Output Jacks – The industry standard RCA jacks provide
easy connection for low level preamp signals. They are gold-plated to
resist the signal degradation caused by corrosion.

13. Input “A” – These L & R inputs feed the preamplifier when the front panel
A/B input switch is set to input “A.”

14. Input “B” – These L & R inputs feed the preamplifier when the front panel
A/B input switch is set to input “B.”

15. Front Output – These full range (20Hz to 20kHz) fadable stereo outputs
connect to the amplifier driving the “front stage” speaker system.

16. Rear Output – These full range (20Hz to 20kHz) fadable stereo outputs
connect to the amplifier driving the “rear stage” speaker system.

17. Subwoofer Output – These full range (20Hz to 20kHz) fadable stereo
outputs connect to the amplifier driving the “subwoofer” speaker system.

Technical Note: Creative installations can use the subwoofer outputs as
a full range center channel with dedicated volume control. Just
remember to keep the subwoofer boost/cut control to its flat (center)
position and always think “center channel.”

18. Power Connector – The power connector provides a convenient
connection for ground, power and remote. The connector uses “screw
lock” terminals to secure the power wires and is removable for quick
disconnects.

19. Input “A” Gain Control – The input gain control is factory preset to
match the output of most source units. It can be adjusted to match the
source unit to tape/VCR audio/video game audio inputs.

ONSIDERATIONS

This section focuses on some of the vehicle considerations for installing your new
PA2. Pre-planning your system layout and best wiring routes will save
installation time. When deciding how to lay out 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 PA2.

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 PA2
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 the appropriate fuseholder and 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.

The following is a list of tools you will need for installing the PA2.
Red power wire Wire strippers

Blue remote turn-on wire Wire cutters
Black grounding wire Voltmeter
Electric hand drill w/assorted bits Jeweler's slotted screwdriver

OCATION

The mounting location for the PA2 should allow easy access to the controls for
making necessary adjustments. The PA2 will most likely be adjusted only at the
time of installation and will not need further adjustment unless changes to the
audio system are performed. To ensure optimum performance, care should be

taken when mounting the preamplifier in the following locations:

Engine Compartment

Mounting the PA2 in the engine compartment will void your warranty. The only
thing that should be mounted in the engine compartment is that big metal thing
that makes the vehicle go fast.

Instrument Panel

Mounting the PA2 in the instrument panel provides optimum access. The unit
should be securely mounted to ensure optimum safety.

Center Console

Mounting the unit in the center console provides optimum access. Be sure the
installation does not interfere with the operation of the gear shift or parking brake.

Glove Box

Mounting the unit in the glove box is adequate, but does not provide easy
access. Glove box mounting should only be done if “Instrument Panel” or “Center
Console” mounting is not acceptable (i.e., maintaining integrity of older vehicles
with metal dashboards).

Under Dash

Mounting the unit under the dash is adequate, but does not provide easy access.
Under dash mounting should only be done if “Instrument Panel” or “Center
Console” mounting is not acceptable. Mount the unit off to the side of the driver's
area to reduce interference with the parking brake, gear shift or operating pedals.

IRING THE

S

YSTEM

For safety, disconnect the negative lead from the car battery prior to beginning
the installation.

1. Wire the Power Connector

The B+ lead should be connected to a source of non-switched 12 volts DC .
Prepare a length of cable from the constant +12V by stripping 3/8" of insulation
from the end of the wire. Insert the bared wire into the B+ terminal of the power
connector and fasten the screw.

NOTE: The B+ lead of the audio system MUST be fused 18" or less from
the vehicle's battery. Install a fuseholder, along with the necessary fuse,
under the hood. Connections should be water tight.

The REM lead should be connected to the remote turn-on or power antenna
output from the source unit. Prepare a length of cable from the source of
switched voltage by stripping 3/8" of insulation from the end of the wire. Insert
the bared wire into the REM terminal of the power connector and fasten the
screw. Total current consumption through this lead is negligible.

The GND lead should be connected to the chassis ground of the vehicle.
Prepare a length of cable (approximately 12" long) to be used for the ground
lead by stripping 3/8" of insulation from each end. Insert one end of bared
wire into the GND terminal of the power connector and fasten the screw.
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 non­anodized screw and star washer.

2. Connect the Source Inputs

Connect the primary source unit cables to INPUT “A.” If adding a secondary
source (tape player, VCR audio, or video game audio), connect the primary
source unit to INPUT “B” and the secondary source unit to INPUT “A” in order
to take advantage of the variable input gain for matching both sources.

3. Connect the Outputs to the Amplifiers

Connect the appropriate outputs from the PA2 to the corresponding inputs on
the amplifiers.

Standard Mounting

The PA2 can be installed in a variety of ways. For installations where mounting
brackets are needed, refer to the diagram below. If your dash or center console already
has provisions for a 1/2 DIN preamp, you may use alternative installation methods.

• Attach brackets to preamp using supplied screws

• Position preamp in desired location (brackets are adjustable)

• If needed, make holes using mounting bracket as a template

• Secure to dash or center console using appropriate screws (not included)

WARNING: DO NOT use bracket screws longer than 4mm into the PA2

– 10 –

ISO-DIN + 1/2 Mounting

The PA2 is also sized to fit import vehicles that accept DIN +1/2 configurations. Using
factory brackets or an installation kit, the PA2 can be coupled with standard DIN sized
radios (like the Rockford Fosgate RFX-8115 CD player) and installed in the dash or
center console.

NOTE: The faceplate may be
trimmed down on each side to
accommodate various trim
panels and installation kits.

Subwoofer Volume

The subwoofer volume controls the output amplitude of the subwoofer outputs relative
to the front/rear outputs. This allows the bass level to be properly matched with the front/
rear speaker system.

Frequency Controls

The frequency controls are used to increase or reduce emphasis in a specific octave of
music. Each control provides up to 10dB of boost or cut to the selected frequency. The
following graph shows the effect of each control at the full boost (+10dB) and full cut
(–10dB) positions. Note that the Subwoofer center frequency is variable and illustrated
at its minimum (40Hz) and maximum (80Hz) positions.

Setting System Gains

The following procedure will set the radio's volume control to a fixed level, allowing
the PA2 to control the level of the audio system.

• Adjust the balance, fader, and tone controls on the source unit and PA2 to their
center positions

• Turn input gains on PA2 and amplifiers to minimum

• Adjust source unit to 3/4 volume or maximum undistorted output

A. If adjusting by ear…

• Play a music track with high dynamic content

• Turn PA2 master volume and subwoofer volume to maximum

• Slowly increase gain control on the PA2 until distortion is barely audible

• If needed, gain controls on each amplifier may be adjusted for more gain overlap

• Before stopping the music track, proceed to “Setting the Signal Strength/Clipping
LED”

B. If adjusting with the aid of test equipment…

• Connect test equipment (oscilloscope, Radio Shack speaker, etc.) to the output
of the amplifier

• Play an “all bits high” (0dB) test tone1. NOTE: You may need to play different
frequencies for systems utilizing crossovers. (i.e.: Play a 1kH 0dB test tone for
high frequency amplifiers and a 40Hz 0dB test tone for low frequency amplifiers.)

• Turn PA2 master volume and subwoofer volume to maximum

• Slowly increase gain control on PA2 and set it for maximum unclipped output

• If needed, gain controls on each amplifier may be adjusted for more gain overlap

• Before stopping the test tone, proceed to “Setting the Signal Strength/Clipping
LED”

Setting the Signal Strength/Clipping LED

This LED is used as a visual indicator for displaying signal strength or clipping level.
We recommend performing the above procedure (“Setting System Gains”) for properly
adjusting the signal strength/clipping LED.

• Play the music track or test tone as described above in “Setting System Gains”

• Adjust the “Clipping LED Trim Pot” until the LED begins to flash

Ajustando las Ganancias del Sistema

El procedimiento siguiente colocará al control de volumen del radio en un nivel fijo,
permitiendo que el PA2 controle el nivel de audio del sistema. Si dos entradas ( A y
B) son usadas, calibre cada entrada indpendientemente usando los siguientes
procedimientos.

• Ajuste los controles de tono, balance y desvanecedor en la unidad fuente hasta
quie estén centrados.

• Lleve las ganancias de entrada del PA2 y los amplificadores al mínimo.

• Ajuste la unidad de origen hasta 3/4 del volumen ó el máximo de salida sin
distorsión.

A. Si el ajuste es a oído…

• Toque una pista musical con un contenido altamente dinámico

• Lleve el volumen Master y de Subwoofer del PA2 al máximo

• Lentamente aumente el control de ganancia (gain) del PA2 hasta que la
distorsión apenas se escuche

• Si es necesario, los controles de ganancia en cada amplificador pueden ser
ajustados para mayor solape de ganancia

• Antes de parar la pista musical, proceda a “Ajustando el LED de Signal Strength/
Clipping”

B. Si el ajuste es con la ayuda de un equipo de prueba…

• Conecte el equipo de prueba (osciloscopio, parlante Radio Shack, etc.) a la
salida del amplificador

• Toque un tono de pruebas de 0dB1. NOTA: Puede que necesite tocar varias
frecuencias para sistemas utilizando divisores de frecuencia. (Ej.: Genere un tono
de 1kHz 0dB para amplifacadores de alta frecuencia y un tono de 40Hz 0dB para
amplificadores de baja frecuencia)

• Lleve al máximo los controles de volumen y del subwoofer del PA2

• Lentamente aumente el control de ganancia del PA2 y ajústelo para una salida
máxima sin distorsión

• Si es necesario, los controles de ganancia en cada amplificador pueden ser
ajustados para mayor solape de ganancia

• Antes de parar la pista musical, proceda a “Ajustando el LED de Signal Strength/
Clipping”

Ajustando el LED de Signal Strength/Clipping

Este LED es usado como inidcador visual para mostrar la fuerza de la señal ó el nivel
de distorsión. Recomendamos desempañar el proceso arriba mencionado (“Ajuste de
Ganancias del Sistema”) para poder ajustar correctamente el LED.

• Toque la pista musical o tono de prueba como se describe en “Ajustando las
Ganancias del Sistema”

• Ajuste el potenciómetro del LED de clipping hasta que el mismo empiece a
parpadear

Réglage du gain du système

Cette procédure vous permet d'ajuster le contrôle de volume de l'unité PA2 par rapport
au niveau injecté par la source.

• Réglez la balance gauche droite, la balance avant arrière et les réglages de
tonalitées de la source et du PA2 à leur position médiane.

• Ajustez la sensibilité d'entrée du PA2 et des amplificateurs au minimum.

• Réglez le niveau de sortie de la source au maximum de niveau sans entendre la
moindre trace de distortion. Généralement cette position se situe deux hiers de la
plage de réglage.

A. Réglage à l’oreille…

• Ecoutez un passage musical contenant une importante échelle dynamique.
Mettre le contrôle de volume du subwoofer au maximum sur le PA2.

• Réduisez doucement le contrôle de gain général sur le PA2 pour ne plus
percevoir la moindre trace de distorsion.

• L’ajustement de la sensibilité de tous les amplificateurs doit être faite pour une
bonne cohérence.

B. Réglage avec des appareiles de mesures.

• Connectez les appareiles de mesures (oscilloscope, voltmètre etc.) à la sortie
de l’amplificateur.

• Lissez une plage quantifiée à 16 Bits (0dB) en régime sinusoïdal Note: vous
devez lire différentes plages de fréquences pour les systèmes utilisant un filtre
actif (écoutez une plage de 40Hz pour le réglage de l’amplificateur de grave,
une plage de 1kHz pour le réglage du médium, et 5.5kHz pour le réglage de
l’amplificateur aigu).

• Tournez le réglage de volume général et subwoofer du PA2 au maximum.

• Doucement faite décroître le niveau du PA2 pour obtenir le niveau maximal
sans déformation.

• Le réglage de la sensibilité d’entrée de chaque amplificateur, devra être ajusté
pour minimiser la déformation.

• Après avoir terminé cette procédure, le réglage de la D.E.L. de signalisation,
(Strength ou Clipping) doit être fait.

Réglage de la D.E.L. de signalisation

Cette D.E.L. est un système de visualisation du niveau de sortie de votre PA2, elle
vous donne deux informations (Strength ou Clipping)compression ou écrétage.
Il est recommandé de contrôler la procédure faite précédemment.(Réglage du gain
du système).
Lire un passage musical et régler le potentiomètre ajustable pour que la D.E.L.
s’illumine uniquement sur les crêtes des signaux les plus élevés.

Einstellen der Eingangsempfindlichkeit

Die folgende Prozedur wird die Lautstärke des Steuergerätes fixieren, so daβ die
Kontrolle des Audio Systems vom PA2 ûbernommen wird. Wenn zwei Quellen (A&B)
benutzt werden, kalibrieren Sie beide Eingänge unabhängig voneinander.

• Die Balance, Fader und Tonkontrollen sollten sich bei dem Steuergerät und dem
PA2 in Mittelstellung befinden. Stellen Sie die Eingangsempfindlichkeit der
Verstärker und des PA2 auf ein Minimum. Drehen Sie den Ausgangspegel des
Steuergerätes auf max. unverzerrte Lautstärke (meiβtens 3/4 des Vollanschlages).

A. Wenn Sie nach Gehör einstellen…

• Wählen Sie einen Musiktitel mit einem hohen Dynamischen Umfang.

• PA2 master Volume und Subwoofer Volume auf Maximum stellen.

• Drehen Sie die Eingangsempfindlichkeit des PA2 hoch, bis Sie die Verzerrungen
gerade hören und drehen dann wieder ein kleines Stück zurück, bis die
Verzerrungen verschwinden.

• Wenn nötig, verstellen sie die Eingangsempfindlichkeit der einzelnen Verstärker,
um eine höhere Lautstärke zu erzielen.

• Stoppen Sie den Musiktitel und fahren Sie fort mit “Einstellen der Signalstärke/
Clipping LED.”

B. Wenn Sie mit entsprechender Testausrüstung einstellen…

• Verbinden Sie die Ausrüstung (Oscilloscope, Radio Shack, etc.) mit dem Ausgang
des Verstärkers.

• Benutzen Sie einen max. ausgesteuerten (0dB) Testton. Beachten Sie:
Möglicherweise müssen Sie verschiedene Frequenzen wählen, wenn Sie aktive
Frequenzweichen benutzen. (Wählen Sie einen 1kHz 0dB Testton für die
hochfrequenten Verstärker und einen 40Hz 0dB Testton für die tieffrequenten
Verstärker)

• PA2 master Volume und Subwoofer Volume auf Maximum stellen.

• Drehen Sie die Eingangsempfindlichkeit des PA2 so ein, daβ Sie maximale
unverzerrte Signale erhalten.

• Wenn nötig, verstellen Sie die Eingangsempfindlichkeit der einzelnen Verstärker,
um eine höhere Lautstärke zu erzielen.

• Stoppen Sie den Musiktitel und fahren Sie fort mit “Einstellen der Signalstärke/
Clipping LED.”

Einstellen der Signalstärkek/Clipping LED

Die LED wird als visueller Indikator benutzt, um die Signalstärke oder ein Clipping
anzuzeigne. Wir empfeheln das System zuvor wie o.a. einzustellen, bevor die LED
angepaβt wird.

• Wählen Sie einen Musiktitel, wie o.a.

• Drehen Sie das “Clipping LED Potentiometer” bis die LED anfängt zu flackern.

Regolazione delle sensibilita

La procedura seguente fissera un volume dell'autoradio, permettendo al PA2 di
controllare il livello del sistema.

• Portare il bilanciamento, fader e controlli di tono alla loro posizione centrale

• Sensibilita di intresso del PA2 e degli amplificatori al minimo

• La sorgente a 3/4 del volume o al massimo livello indistorto

A. Se si regola ad orecchio…

• Suonare una traccia musicale con elevato contenuto dinamico

• Portare il volume principale e del subwoofer al massimo

• Aumentare la sensibilita del PA2 fino ad udire un minimo di distorsione

• Se necessario, le sensibilita degli ampkificatori possono essere aumentate

• Interrompere la traccia musicale e continuate dalla sezione “Regolare l'intensita
del led di segnalemassimo/clipping”

B. Se si regola con l'ausilio di apparecchiature di prova…

• Collegare le uscite dell'amplificatore agli strumenti test (oscilloscopio o altoparlante
prova)

• Impiegare una traccia test (1) incisa a 0dB. Nota: potrebbero essere necessaria
tracce a diverse frequenze per sistemi impieganti un crossover elettronico (es.
impiegare una traccia a 1000Hz per le medio alte e 40Hz per il subwoofer)

• Portare il controllo di volume principale e del subwoofer al massimo

• Aumentare la sensibilita di ingresso del PA2 fino a raggiungere la massima uscita
indistorta

• Se necessario, le sensibilita degli amplificatori possono essere aumentate

• Interrompere la traccia musicale e continuate dalla sezione “Regolare l'intensita
del led di segnalemassimo/clipping”

Regolare l'intensita del led di segnalemassimo/clipping

Questo led e impiegato per visualizzare la massima intensita del segnale od il suo
clipping.

• Consigliamo di impiegar la procedura sopra descritta per un corretto funzionamento
del LED

• Regolare il potenziometro “Clipping LED Trim Pot) fino a quando il LED
lampeggia
