CONTROL FUNCTIONS
1. Inputs - The inputs use a balanced input circuit to help minimize induced noise. They are also
designed to handle very high signal voltages up to 15 volts.
2. Outputs - The outputs should be connected to a component auch as a crossover, equalizer, or
amplifer. Note: The RTLDBP should be inline before a crossover.
3. Dash Remote Control Connector
4. Power Connector
5. Para-Bass Controls - The two knobs control the Para-Bass functions of the RTLDBP. The SWEEP
knob picks the desired center frequency to be maximized. The WIDE knob adjusts how wide of a
frequency range the RTLDBP will effect.
6. PFM Subsonic Filter Switch - The RTLBDP utilizes a PFM Subsonic Filter Switch which will help
with speaker control and power management. The PFM Subsonic Filter Switch comes with three
frequency selections: 35Hz / 50Hz / 80Hz. On most systems, setting the switch at 35Hz is ne. A
higher frequency setting will provide even more protection to your system. Often a higher
frequency actually sounds louder and cleaner.
7. Bass Maximizer Indicators: These three LED indicators ash when the bass maximization circuit
is activated.
8. Power On LED
9. Input Grounding Jumpers - For most systems the jumper can be left in the BALANCED position. In
some systems, the source unit may look for a ground through the RCA connectors. In this event,
the jumpers should be moved to the UNBALANCED position.
10. Ground Isolation Jumpers - Occasionally alternator whine may appear in a system because the
source unit and amplier may use different grounding. Alternate grounding connections have
been provided to help in this situation. Make sure the system is turned OFF before these jumpers
are removed.
11. Bass Output Control Jumpers - Not all systems are designed the same. Some are designed
strictly for SPL (sound pressure level) while other are a little more tame. The Bass Maximizer
circuit can either increase or decrease the signal voltage of the Bass Restoration Circuit.
Depending upon the system, these jumpers may be changed to a higher or lower setting to
maximize the bass output and protect your speakers. In most systems the factory setting should
be ne. It is recommended to try the factory setting rst.

ADJUSTING THE PARA-BASS CONTROLS
The bass response in a system is affected by four factors:
1. The acoustics of the vehicle
2. The location of the speakers
3. The music being played
4. The speakers and speaker enclosures
The RTLDBP was developed to help restore any low frequencies lost due to varioations in the
recording process. However, the acoustics of various environments are different.
The SWEEP control allows the user to select a center frequency (the frequency most affected)
between 27 and 63 Hz. The WIDTH control then allows the user to control the shape of the lter
centered around the SWEEP frequency.
SETTING THE BASS OUTPUT CONTROLS
The RTLDBP is a powerful bass component. This device is equipped with several different Bass
Output selections. If the settings need to be changed, please use the chart below for guidance. It is
recommended to listen to the factory setting before changing the Bass Output settings.
Recommended Settings:
Setting Amplier Input Voltage Minimum Speaker Size
2.5V 3V or Less 8"
5V 5V or Less 10"
7.5V 7.5V or Less 12"
10V 10V or Less
FEATURES
Bass Driver - The RTLDBP contains a Bass Driver circuit that accurately recreates and injects low
frequency information back into the signal path. This means that the RTLDBP will give more bass
impact to music sources, even older compact discs and tapes.
Bass Equalization Circuit - The RTLDBP has a unique equalizaition circuit that contours the restored
bass to the speaker systems.
Dash Mount Remote Control - The RTLDBP comes with a Dash Mountable Remote Control that allows
the user to control the bass processor without having to leave the driver’s seat. The LED indicator will
become brighter as the bass is increased, and will dim as the bass is decreased.
Bass Maximizer Indicator - These three LED indicators will ash when the bass maximization circuit
has been activated.
PFM Subsonic Filter Switch - This unique feature has the ability to ne tune the bass response of any
system. Why waste power on nasty subsonic information when the PFM Subsonic Filter Switch can
help to clean things up?
Bass Output Control - The RTLDBP has the ability to produce large amounts of deep, mind blowing
bass without damaging the speakers. The Bass Output Control circuit allows the RTLDBP to maximize
the bass output of any audio system while restraining destructive bursts.

TROUBLESHOOTING
The unit does not turn on and / or the power indicator LED is not illuminated:
1. Make sure that the B+ and GND wires are not reversed.
2. Make sure that all power wires are properly connected and have the appropriate potential
(11-16V).
3. Make sure that all fuses are intact.
Experience high audible distortion or low output volume:
1. Make sure that the input and output levels are set correctly. The input should match the source
and the output should match the sensitivity of the host.
2. Make sure that the crossover settings are correct. For high “Q” systems, set the crossover half
an octave above the desired point. For low “Q” systems, set the crossover one octave or more
above the desired point.
Experience whining or engine noise:
1. Make sure that the GND connection is secure and that the conductor (wire) is not too thin and
unnececessarily long.
2. Make sure that the B+ wire is not too thin and unnecessarily long.
3. Change the power source. Try taking power from a different point.

FUNCIONES DE CONTROL
1. Entradas - Las entradas utilizan un circuito de entrada equilibrada para ayudar a minimizar
el ruido inducido. También están diseñados para manejar muy altos voltajes de señal de hasta 15
voltios.
2. Salidas - Las salidas deben estar conectados a un componente, como un crossover, ecualizador,
o amplicador. Nota: El RTLDBP debe estar en línea antes de un crossover.
3. Control remoto que se monta al tablero
4. Conector de alimentación
5. Controles Para-Bass - Los dos mandos controlan las funciones para-Bass del RTLDBP. El mando
BARRIDO recoge la frecuencia central deseada para maximizar. El mando ANCHA ajusta el
ancho de un rango de frecuencia de la RTLDBP afectará.
6. PFM interruptor ltro subsónico - El RTLBDP utiliza un conmutador de ltro subsónico PFM que
ayudará con el control de altavoz y de gestión de energía. El interruptor de ltro subsónico PFM
viene con tres selecciones de frecuencia: 35Hz / 50Hz / 80Hz. En la mayoría de los sistemas,
poniendo el interruptor en 35Hz está bien. Un ajuste de frecuencia más alta proporcionará aún
más protección a su sistema. A menudo, una mayor frecuencia en realidad suena más fuerte y
más limpio.
7. Bajo indicadores maximizador: Estos tres indicadores LED parpadean cuando se activa el
circuito de la maximización de graves.
8. Encendido LED
9. Los puentes de conexión a tierra de entrada - Para la mayoría de los sistemas el puente se puede
dejar en la posición de equilibrio. En algunos sistemas, la unidad fuente puede buscar un
terreno a través de los conectores RCA. En este caso, los puentes deben moverse a la posición
desequilibrada.
10. Puentes de aislamiento de tierra - Ocasionalmente zumbido del alternador puede aparecer en un
sistema porque la unidad de la fuente y el amplicador pueden utilizar diferentes a tierra.
Conexiones a tierra alternativos se han proporcionado para ayudar en esta situación. Asegúrese
de que el sistema esté apagado antes de retirar estos puentes.
11. Puentes de control de salida de graves - No todos los sistemas están diseñados de la misma.
Algunos están diseñados exclusivamente para SPL (nivel de presión sonora), mientras que otros
son un poco más dócil. El circuito Bass Maximizer puede o bien aumentar o disminuir el voltaje
de la señal de la Restauración Circuito Bass. Dependiendo del sistema, estos puentes se pueden
cambiar a un ajuste más alto o más bajo para maximizar la salida de graves y proteger sus
altavoces. En la mayoría de los sistemas de la conguración de fábrica debe estar bien. Se
recomienda probar el establecimiento de la primera fábrica.
