Upgrade
There are two ways to upgrade your DAC - changing the DAC PCB to a higher 24-bit version and adding an optional
ADAT board. To upgrade your DAC or add an optional ADAT board remove the screws indicated on the picture 1 and 2
with a screw driver.
Carefully pull the top part of the case. Use a flat object to carefully pull up the DAC PCB that is located on the picture 3.
Install the new PCB and softly push it down on the main board.
To add an ADAT PCB just install it as per picture 3. Put the top part of the case back and assemble it with the screws.
Turn on the DAC. The display will show its current model and presence of ADAT board inside. Note that opening the case
will cancel your 90 days warranty period.
