Connecting Your Micro DAC and Ultra Micro DAC to your Computer.

The most convenient and common way to get a high quality signal out of your computer is with USB output. (If you have optical or coaxial outputs on your machine, then skip to the next section.) Simply plug a USB cable into your computer, and plug the smaller end into the back of the amp. In most cases your computer will instantly recognize the amplifier, but you will need to restart your music management program. If your computer does not recognize the device, restart; if it still is not recognized, you may need to go into your control panel/audio devices or system preferences/sound output and select ‘USB Audio Codec’ as your default audio device. Make sure to switch the Digital Input Selector Switch to‘USB’.

Plug the mini-to-mini cable into the line input of the Amp and line output of the DAC.
