IMPORTANT NOTICE
It is unlawful in most jurisdictions for a person to drive a
motor vehicle which is equipped with a television viewer or
screen that is located in the motor vehicle at any point
forward of the back of the driver’s seat, or that is visible,
directly or indirectly, to the driver while operating the
vehicle.

SDB45 System Overview
TheSDB45isa versatile audio/videoswitching system andhas thecapacity for four Audio/Videoinputs and fiveAudio/
Videooutputs alongwitha separate audiooutputfor connectinganFM modulatortothe vehicle radio.
TheSDB45 consists ofaSignal Distribution Box(SDB)andtwo Control Stations(CS)along with cablingfortwosignal
sources(SDBSC) and cabling(CSSC)for connecting twovideoscreens.
Additionalcontrol stations (CS),SignalDistributionBox SourceCables (SDBSC),aMasterControl Station(MCS) and
a Game Control Station (GCS) can be purchased to further enhance the system.
Each CS is comprised of a control station, a trim ring, a DIN cable for connecting the control station to the SDB, a
control station source cable (CSSC) for connecting the output of the SDB to a video screen. Each control station has
avolume control andtwoheadphone jacks forlisteningto the selectedsource.In addition, eachcontrolstation has an
IR sensor that allows each user to control the source component that is selected on the control station.
TheOptional MCS iscomprisedofa master controlstation,aDIN cable forconnectingthemaster control stationtothe
SDB,a control stationsourcecable for connectingtheaudio output oftheSDB to anFMmodulator (which isincluded)
and a trim ring.
The MCS can switch the audio from any of the four A/V sources to the FM modulator (or to the low-level input of a
receiver) so that the audio can be played through the vehicle radio. The MCS also has the capability of setting a
10-minute delay. When the delay is enabled, the system will remain on for 10 minutes after the vehicle is turned off.
The MCS also has an IR sensor for controlling the source components.
(NOTE: The MCS is NOT required for the system described above.)
The optional GCS is comprised of a game control station that has RCA jacks on the front and back, a 15-foot RCA to
RCA cable and a trim ring. The GCS can be used as a game port for easy access when connecting a video game,
camcorder, portable DVD or other A/V input device.
The SDB45 can be used with essentially any source component and any video screen available.
(NOTE: The IR repeater in this system may not work with non-Audiovox components.)

1. Decideupon system configurationandoptions that
willbe installed (i.e.:whatcomponents, VCP,DVD,
TV Tuner, Video Game, Monitors, etc.).
2. Reviewall manualstobecome familiar withelectri-
cal requirements and hook ups.
3. Decideupon mountinglocationsofall components
and method of mounting.
4. Prep the vehicle by removing any interior trim nec-
essary to gain access to vehicle’s wiring as well as
allareas where interconnectingwireharnesseswill
need to be located. If any access holes need to be
cutintothevehicle(headliner, other trimcomponents
etc.), this should be done now as well.
5. Routethe wiringharnessesthroughout thevehicle
as necessary. (Refer to the Wiring Diagram Sheet
attached as well as the wiring instructions for the
individual components and accessory options be-
ing installed). Be sure that all wiring is protected
from sharp edges and is routed in such a manner
thatit willnot bepinchedwhen allcomponentsand
interior trim are fully installed. Be sure to leave
enough slack in the wiring at each component to
allow working room.
6. Remove all A/V system components from their
packaging and place them loosely in the vehicle at
their respective locations.
7. Connectall componentstogether(electrically) and
verify proper operation of all system functions.
Note: This is best done BEFORE components have
been permanently mounted.
8. After verifying proper operation of the system,
proceed to mount each component.
9. Whenallcomponentsaremountedrechecktheentire
system to be sure it is functioning correctly and
ensure that no wiring was pinched or connected
improperlyduringfinalinstallation. Use the supplied
cable clamps on the control station interconnect.
VEHICLE PREPARATION
1. Locate a constant power source (+12 Vdc at all
times) and an accessory power source (+12Vdc
present when the ignition key is in the accessory
and run positions. 0Vdc should be present when
the ignition key is in the OFF position). Generally,
these wires can be found at the ignition switch or
fusebox. (NOTE: Ensure that the constant and
accessary power are fused at their sources. Failure
to do so may result in vehicle wiring damage.)
Groundthe Blackwireto a chassisgroundclose to
the mounting location of the SDB box.
2. The mounting method and location will vary from
vehicleto vehicle,sothis manual willonlyfocus for
the installation of SDB45 A/V Signal Distribution
System in the package.
3. Generally, the best locations for SDB45 System
components are:
a) SDB Trunk
b) MCS Doorpillarneardriver,dashboard or
console
c) CS Door pillar near passenger or console
d) GCS Rear deck or console
Note: Atemplate is includedatthebackof this manual
for mounting the control station.
GENERAL INSTALLATION APPROACH:

Output Connector Layout of the SDB
1. Audio Output L/R (RCA Jacks)
These jacks accept the red and white RCA plugs
from the Master Control Station Source Cable and
transmit the left and right audio output signals to
the FM Modulator (MCSFMM). (Note: In order to
routethe signalstothe modulator,amaster control
stationis required. The MAINPOWER buttonmust
be pressed along with the FM POWER button on
the Master Control Station.)
2. Master Control Station Input (8-pin Din)
This 8-pin jack provides the interconnection from
theSDB AudioVideoSignal Distribution Boxtothe
MasterControl Station.
NOTE: This cable is different from the other 5-Din
cables. Be sure to use Din cable part
number MCSDIN.
3. 12VDC Output for FM Modulator
This jack accepts the black barrel type power
connector from the Master Control Station Source
Cable. This supplies power to the FM Modulator.
4. Audio Output L/R (2-RCA Jacks)
These jacks accept the red and white RCA plugs
and apply the left and right audio output signals to
the user monitor; (Example LCM4000, LCM5600
etc.). Use the Control Station Source Cable
(CSSC).

Game Control Station (Optional)
The game control station is a set of RCA jacks that
allow the user to plug in the audio/video outputs of a
video game, camcorder, portable DVD or other audio/
video source into the SDB45 system. It provides a
readily accessible A/V input without having to access
the jacks on the SDB box.
ViewingaVideoSource/VideoGameUsingtheGCS
To use the GCS, plug in the A/V source to the GCS
RCA jacks, turn the source on and use the source se-
lect button (S) on the control station to access the
source to which the game control station is wired.
