4 Testing
Installation
The HagUsb plugs into your computer via a standard USB cable. The bus itself supplies
power, and the LED should light up immediately. After a few seconds, the operating
system (XP or OS-X) will recognize and enumerate the new device, configuring it as the
new audio output port. All computer sounds will then be routed to the HagUsb.
Connect standard headphones and try playing a CD. Volume is controlled by software,
so make sure it is not muted. If using the S/PDIF output, connect via a quality 75-ohm
coaxial cable to your DAC. If you experience difficulties, contact the factory for help.
