The USBPre is a digital system made up of many
components. USBPre can be thought of as a com-
bination of stand-alone products - a stereo micro-
phone preamplifier, A/D converter, S/PDIF format
converter, D/A converter, and headphone amplifier
in a single box. The convenience of having all of
these components in a single, compact product
powered from the computer is obvious. The block
diagram below shows one analog input of the
USBPre.
