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

When power is applied to the unit and the switch located on the rear is in the on position, the DAC is
powered up and ready to be turned on. If you would like to manually disconnect the power from the unit, the
switch on the rear is where you would want to do so. To prevent power surges, we recommend using quality surge
suppressor equipment. Turning the switch off on the rear of the unit will also protect against surges and spikes
should some occur without proper protection.

CAUTION: Disconnect the power cord or put the power switch in the off position before making any
connections to your DAC to minimize the risk of possible amplifier, and loudspeaker damage. Power up your
DAC after all final connections have been made and checked.
The input and output connections you will find on the DAC-2 are made of nothing but the best. The
RCA (unbalanced) output, and Coax input jacks are made with high quality gold plated copper, and should be
properly connected with interconnects of the same value. The Neutrik XLR (balanced) connectors are the finest
balanced connector on the market, and are the best possible option for connecting your DAC to your
preamplifier. The Toshiba Toslink inputs offer optimum connection with SPDIF sources without the possibility
of creating any ground loops.
Using the new W4S power and interconnect cables would be a great way to ensure your system is closer to
what we call “our reference”. We are now offering superior cables at an affordable rate that anyone can afford.
