The revised user interface is more responsive to user commands and it is more compatible with automation systems. A new AUTO-ON function allows automatic startup using a switched AC source. The DIM function has been improved so that DIM always reduces the volume by 20 dB from any volume control setting. The volume control setting is stored in nonvolatile memory and is recalled when unit is turned on. The DIM state (DIM on or DIM off) is also stored in memory.
After installing the upgrade kit your unit will be reset to the factory defaults including the USB mode. Factory default is USB 1.0 and if you were using USB 2.0 you will need to change the USB setting back to 2.0 by holding the input up and down buttons at the same time (or the USB on the remote) for a full 3 seconds.

Version 2.3 is designed to make your DAC2 D manufactured before 11/14/2018 easier to use. This upgrade makes the user interface on the DAC2 D resemble that of the DAC3.
