JDS Labs ODAC Operating instructions

Hello! I've reviewed the Operating Instructions for the JDS Labs Objective ODAC. This document details how to connect the DAC to your computer and amplifier, as well as provides troubleshooting steps for common issues, such as no sound in one channel or distorted output. It also emphasizes that it is a line-output device and needs an external amplifier. I'm ready to answer your questions about setting up and using your device.
Can I connect headphones directly to the ODAC?

What operating systems does the ODAC work with?

What audio settings are recommended?
