No. The front USB connection is designed for use with Apple iOS devices such as iPods and iPhones, or for streaming via the Bluetooth dongle, but it is not designed to connect to a computer directly. Consider a USB DAC or if your computer has a coax or optical audio output you could connect that to an input on your Rotel unit instead.
