More features that can be found in the setup menu are volume Min/Max settings that can be set
differently for each type of input. The volume table for the DAC is 70 steps in size and offers different size
steps depending on the location of the step. When a system doesn’t have enough gain to utilize the bottom
several steps, you can remove them from the table by setting the volume minimum setting to with-in the
playback range of the system. Because of the high output level of the DAC, it may offer the possibility of
higher levels than needed. To prevent the possibility of amplifier overdrive, or possible speaker damage, we
recommend setting the volume Max level with-in your personal preferences. The features listed above are
some of the ways the DAC can adapt to everyone’s system for optimal integration without the worry of having
too much or too little gain.
Example:
When the minimum level for the corresponding input is set to 5, the maximum level will be 65. Basically the
min level is the amount of steps skipped in the first position. When used, the min level is subtracted from the
70 possible steps total. With an inefficient system requiring a volume level of 12 to hear anything, a min level
of 10 removes steps 1-10 and max equals 60. The volume table offers from 3db to 1dB steps as follows: 0 =
mute; steps 1-9 = 3dB; steps 10-24 = 2dB; steps 25-70 = 1dB
