The most convenient and common way to get a high quality signal out of your com-
puter 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 de-
vice, 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.
- Switch the Digital Input Selector Switch
to‘USB’.
