DACs.
Digital Connections
There are two methods for extracting digital signals from your computer. The universal
serial bus (USB) connection is the de-facto standard for just about all peripherals: printers,
digital cameras, etc. The USB allows the computer to speedily recognize a connected device.
Some computers also incorporate the Sony/Philips Digital Interconnect Format (S/PDIF), a
coaxial connection with excellent transfer properties.
USB Audio and Performance Optimization
USB specifications define a standard interface: the USB audio-device class, which allows a
software driver to work with the currently available USB sound devices. Microsoft
Windows, Apple Mac and many Linux versions provide support for USB audio devices.
NuForce Desktop USB DACs convert USB digital data to the analog signal headphones and
amplifiers require. Equally as important, how the USB DAC performs affects sound quality.

Some Optimization Tips
To minimize noise and dropouts, connect your audio interface to a port at the back of your
computer. Generally speaking, ports on the computer’s face, monitor or keyboard don’t
perform as well.
