Frequently Asked Questions:
Q1. How do I power the DAC-Q4?
A: You will need to use the supplied Micro-USB cable to power it, I recommend using the PC-USB port/5V to power it. Note: The Micro-USB cable cannot be fully inserted into the device power port, please do not force it. Subsequent revisions have been made.
