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.

Power Out

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.
