Storing Presets

While in any of the parameter menus, you can save any changes to settings by pressing the desired number button that you wish these settings to be saved to. The parameters which have changed will replace the default parameters in the preset.

When a preset is being saved the following screen displays.

Sensitivity

The sensitivity parameter adjusts the unit’s gain (input attenuation) to match the corresponding head unit. This allows you to run the head unit, DCX-730, and amplifiers at their optimum gain settings for minimum noise. The attenuation setting allows further reduction of the input level to allow inputs up to 12 volts to be accommodated.

Input Level:

0 to 2.9V

Attenuation:

0db to -12db (when adjusted to -12db the input

 

level is now 0 to 12 v.

When adjusting the system you should avoid running the DCX-730 into clipping. Use the built-in clip indicator for reference. Clipping in the digital domain can be much harsher.

NOTE: Because of the nature of the analog/digital audio conversion process, the sensitivity setting allows for 6dB of headroom (that is, an input level of 1 V rms drives the sensitivity setting of 0.5V rms to near clipping) prior to digital clipping.

Volume

The volume parameter adjusts the output level of the DCX-730. For normal use this would be set to approximately -10 to -15dB. Then adjust the sensitivity of the amplifier following normal gain adjustment guidelines provided with the amplifier.
