How do I connect the ZEN DAC 3 to my computer or phone?
You connect the ZEN DAC 3 to your source using the included USB-C cable — plug the USB-C end into the DAC and the other end into your computer or compatible phone. It uses USB audio to bring digital audio into the unit’s DAC section and convert it to analog sound for headphones or line outputs.
Quick take

Do I need an external power supply?
Not necessarily. You can power the ZEN DAC 3 directly from your computer’s USB port, but many Crutchfield customers and our experts recommend adding a quiet external 5 V power supply to improve sound quality by reducing noise and freeing the USB cable for data alone.

USB power works out of the box

Optional 5 V supply (like iFi’s iPower2) can clean up noise

Cleaner sound with dedicated power suggested
How do I hook up my headphones or speakers to it?
Plug headphones into the front balanced 4.4 mm or standard 1/4″ outputs. For active speakers or a stereo amp, use the RCA line outputs on the back. There’s also a variable/fixed switch to choose whether the ZEN DAC 3’s volume knob controls output level (variable) or acts as a pure preamp (fixed).
