INSTALLATION

1. Read this manual carefully and in its entirety before installing the
DCX-730.

2. Always disconnect the battery or remove the fuses for circuits you
will be working on.

3. Check for clearance of any hazards such as wiring harnesses or
heater core before mounting the equalizer to any panels in the
vehicle.

4. Mount the DCX-730 controller and processing module in a location
that is easy to access. The processing module should be mounted
within the passenger or trunk compartments. Do NOT mount the
processing module in the engine compartment.

5. Route all power wires and audio cables away from sharp metal
edges that can cause shorts to ground and any moving parts that
can tangle the wires such as heater controls or wiper motors.

6. Route all power and signal cables as far as possible from other
vehicle wiring harnesses. Loom when appropriate.

7. It is recommended that the DCX-730 processor be grounded at a
chassis point (preferably bare or scraped sheet metal) near to where
the processor is mounted. The DCX-730 controller should be
grounded at a chassis point (preferably bare or scraped sheet metal)
other than the factory head unit ground wire or under dash brackets.

8. Use only the supplied machine screws to mount the DCX-730 or
damage to the circuitry could occur.

2. Arrows. Use the arrow buttons to navigate through the menus and to adjust a
menu setting.

3. LCD Display. Backlit display, soft-blue background for easy viewing at night.

4. Presets. Five preset buttons to allow you to select from 5 settings that you
have entered. Examples of these presets would be for the type of music,
different volume settings, different audio sources.

5. USB. Open this cover to plug in a mini-USB connector. This port is used to
upgrade the software in the controller and to allow the installer to load in
parameters for known vehicle acoustical environments using a pc.

The controller connects to the processing module (shown below) by means of a
long cable at the back of the controller. This cable powers the controller from the
processing module and and gives the audio settings to the processing module.

The top panel has a green power on indicator LED and a red clipping (out)
indicator LED. If the clipping LED indicator is illuminating, the DCX-730 requires
adjustment. Damage to your speakers could result from the DCX-730 being
improperly adjusted.

PROCESSING MODULE

The processing module is designed so that it can be integrated into almost any
installation. All of the audio flows through the processing module prior to going to
the amplifier. This allows the processing module to be mounted in a remote
location where the audio signal path length can be kept to a minimum. The unit
must be mounted in a location where it will not be subject to excessive
temperature or vibration. The processing module should be installed in the
passenger compartment or the trunk of the vehicle. Do NOT install this unit in the
engine compartment, as the unit will be exposed to extreme temperatures and
weather.
