Headphone Gain Setting
The default gain setting of the headphone amplifier (4 Vrms output)
is more than adequate in almost all situations. For those desiring a
slightly higher power, the headphone amp gain can be increased
with internal jumpers.
Before opening the cover, be sure to unplug the AC power
cord from the D2 DAC. Failure to do so can result in
electric shock.
(1) Unplug the AC power cord from the D2 DAC.
(2) Wear an antistatic wrist strap and affix its alligator clip to
grounded bare metal, such as the metal chassis of a desktop
computer that is connected to AC mains. Failure to do so can
damage the components inside the D2.
(3) Remove only the 8 flat-head screws from the side of the DAC (4
on each side) using a 1/16” hex driver.
(4) Remove the top cover by pulling it up
vertically
. Avoid pulling it
toward the back as it will interfere with the PCB.
(5) Locate the two 2x2 headers near the front of the D2. Insert the
four jumpers, making sure that the jumpers are inserted in the
correct orientation as shown in the photo.
